The process of building your new home starts long before you lay the foundations. One of the most important considerations to make is whether or not the land that you’re planning to build your new property on is suitable for your construction project. When planning the build of your own home, there are many different surveys that might be worth getting in order to ensure that you’re protected against future issues with the property and to make sure that everything you do is in line with the laws and legislation that surround protected tree and wildlife species in the UK.

When building your own property on a plot of land, you will need to consider any protected tree species, or wildlife species such as bats and badgers that might be present and how you are going to ensure that their natural habitat is protected throughout and after the construction process.

different surveys when building a new home

Biodiversity Net Gain

Part of getting various surveys carried out when building your own property is due to biodiversity net gain. This is a concept where the state of biodiversity of an area is improved rather than damaged when land development projects are complete. It is worth having a biodiversity net gain consultant as part of your project to ensure that the land is preserved as much as possible, natural habitats are retained, and biodiversity loss is prevented. Specialist consultants can provide you with more information on the biodiversity of the area and recommend specific surveys that are worth having carried out in order to preserve it.

Tree Survey

If there are various trees located in the area you are planning on building your home, then it’s worth having a tree survey. This might be a legal requirement if you know or suspect that there are protected tree species in the area. Along with this, it can also help you prevent any issues that might arise from building your property too close to trees, which can cause problems like subsidence when the roots take moisture from the soil around the property foundation. A tree surveyor or arborist is the best professional to conduct a thorough tree survey, which will provide you with more detailed information about the trees in the area and how they will be taken into consideration when building your new home.

Badger Survey

Badgers and their setts are a protected species by law in the UK. If you are building on land where there may be badgers present, or any other type of protected wildlife, then you should have a thorough survey carried out to find out more about where the badgers are and how you should proceed with the building plans to ensure that they remain protected throughout. It’s important to know how your project might impact badgers and other wildlife in the area, what measures you can take to ensure that local wildlife is protected and undisturbed throughout the process, and more. This will help you avoid problems down the line and the risk of delaying your project if you find protected species present during the construction process.

Bat Survey

Another protected species in the UK that is worth surveying for before you start your new home build protect is bats. It is illegal to kill bats or move them from their natural habitat in the UK, so it’s especially important to survey for them if you are planning a project that involves renovating old buildings, which bats are often present in. A custodial sentence or fine are common consequences of harming or disturbing bats in their natural habitat, even if you did so unintentionally. It’s best to have a bat survey carried out by a professional to get more information regarding the presence of bats on the land or in any buildings on it. The survey will also provide you with further information going forward to help you work around any bats that might be present on the plot and ensuring that their natural habitat is protected.

Soil Survey

Boggy land, tipped areas, and running sand are all signs of poor ground conditions that might cause serious issues with your construction project further down the line if you do not investigate them thoroughly at the start. Before you begin the process of construction, it’s a good idea to have a survey conducted on the land itself, allowing you to find out more about what’s present underneath the topsoil, how easy or difficult it is going to be to build on, and if any additional work should be conducted beforehand when it comes to making sure that you are fully prepared for starting your project and the land is safe to build on. This might be a survey that you have done on its own, or as part of a larger land survey that can include other aspects such as odd-shaped sites, obstacles and more allowing you to go into the project fully prepared.

How To Pursue A Career In Environmental Management

Structural Building Survey

If you are not building your new home from scratch but are rather going to be convert or renovate a derelict property that already exists, then it is worth having a survey carried out on this property before you get started. In most cases, a full structural survey is the best option to get before you start, as this will give you a better idea of the condition of the building and how safe or even possible it is to complete the conversion or renovation that you are hoping for. This survey will give you a more in-depth look into the overall condition of the building including uncovering any issues that might not be immediately obvious when you look at it. This can help you not only determine what kind of preparatory work needs to be done before you can start the project but will also help you budget better.

Whether you are planning to build a property from the ground up on a plot of land or have an old building you are planning to convert, there are various surveys that are worth getting to help you prepare the best way forward.

How Can Oil-Free Air Compressors Benefit The Environment?

If you already have an air compressor, you will be aware of how they are an incredibly valuable tool for industries and DIY enthusiasts. Commonly used to power pneumatic tools but can be used for a variety of applications. Air compressors provide you with complete power over spraying, nailing, sanding and hammering at a fraction of the time it would take with manual tools.

You can also find these smaller sized air compressors everywhere that are very portable and best at doing small work. Bob Robinson of BestOfMachinery swears by these portable tools. “Small air compressors essentially push air from the tank in the unit, into the tools that you want to use for either DIY, hobbies or work purposes without the need to lug heavy stuff.”, he commented.

These machines can also be used for inflating tyres, auto repairs and even creating home-made snow machines. Sandblasters, impact wrenches, grease guns, die grinders and angle disc grindles can also be attached.

We all love our power tools and would be lost without them; however, we are becoming more aware regarding the issue of carbon emissions. Reducing our carbon footprint is one of the most important things companies and individuals can do in their lifetime. Small changes within your business and homes can be a great start to decrease our carbon emissions and help save the planet.

If you are looking to purchase your first air compressor or to update an existing model, Direct Air has created a guide on why an oil-free air compressor is a great choice, not just for the environment, but to help you save on energy bills. You can see their full range of oil-free air compressors at https://www.directair.co.uk/products/oil-free-air-compressors/.

Every air compressor requires lubrication in order to efficiently and safely draw in air to its cylinder, commonly using a piston movement. The traditional method to achieve this is using oil, while oil-based air compressors do have their benefits as they are more robust and can handle large-scale applications, they are higher in initial cost, harder to maintain and far heavier than their oil-free counterparts.

Oil-free air compressors gain lubrication through a non-stick coating, generally Teflon. As extra elements to hold oil are eradicated from these machines, they are far lighter and smaller than oil-based air compressors which make them ideal for applications that are not static. Due to less components, oil-free air compressors are often cheaper to purchase.

Oil-based air compressors must remain static and upright when in use, oil-free are far more versatile. As you do not need to consider the oil flow, they can be positioned wherever you see fit. They are also operatable at any temperature, oil can become viscous in cooler climates and can cause problems when attempted to start the motor, oil-free erases this issue.

With these benefits in mind, you can achieve even more with your oil-free air compressor by helping to reduce the use of fossil fuels maintain the planet’s natural resources. You can also make a direct impact on your running costs, saving you and your business money on your energy bills.

With an oil-free air compressor, all costs to collect and dispose of oil-laden condensate will be removed, not to mention the initial cost of the oil itself. These compressors are less wasteful as they do not require the replacement of the air/oil separator and filtration elements which are required to get rid of oil aerosols, these parts are notorious for wearing down quickly. You will not needlessly be sending these parts to landfill and be bearing the cost of new ones on a regular basis.

If you are worried about direct harmful emissions from your air compressor, oil-free air compressors produce the purest form of air which will reduce any negative impact into the atmosphere, great for the planet and for those working around it. You will also not have the trouble of potentially contaminated products from oil spills during projects.

A big bonus of oil-free air compressors is that they are safer than their counterparts, as there is no oil, you eliminate the risk of compressed air pipeline fires. An incredibly important factor to consider for the safety of you, your staff and your premises.

Oil-free air compressors can dramatically reduce your energy bills compared to the oil-based counterpart as they require less energy to run which will cut down your environmental impact. Oil-free air compressors do not need increased forces of power when the unit has a drop in the filtration in the downstream pressure, unlike oil-based. Oil-free units can, on average, unload in 2 seconds of your command which only uses around 18% of its full load horsepower.

Of course, all machines come with their downsides and oil-free air compressors are no exception. Oil-free air compressors are known to generate more noise which can be an annoyance and hazard to those using it and those around them.

There is a solution, you can invest in a low-noise air compressor. These reduce noise levels to around 40dB. The lowest safe level is considered 60 dB and anything over 80dB can cause long-term problems with hearing.

With the addition of an acoustic cylinder to contain this noise, opting for a low-noise air compressor is an investment worth making. It is recommended when using any power tool that protective gear is worn to eliminate lasting damage and long-term effects, even with a low-noise machine.

If you were considering purchasing a new air compressor or have simply been doing research on them, you should now have a comprehensive understanding of the benefits an oil-free air compressor possesses.

How Biofuel is Impacting Our World in 2023

  By | | , ,
3 Comments

The world is changing. We’ve come a long way from the days when the only option for fuel was the fossil-fueled version. However, more strides can be made. In 2021, fossil fuels still accounted for 79% of U.S. energy consumption. While it’s hard to leave behind our dependence on it, fossil fuels must eventually go, and renewable energy sources must take their place.

In 2021, renewable energy contributed only 12% to the total U.S. energy consumption. Of course, that rate is gradually growing upward. Now, you can find renewable fuels and even hybrid engines that combine both traditional petroleum-based fuels and biofuels. What are these biofuels?

how biofuels is impacting the world

The best way to explain them is by looking at how they work and what they do for our planet’s future. Biofuel is one of the renewable energy sources that contributed to the U.S. energy consumption in 2021. Of all the other renewable sources, biofuel was the joint-second most popular one, alongside hydroelectric energy. As time progresses, we’ll see this energy source contributing more to our energy sector and the environment.

Having said all that, here are a few ways biofuel is impacting our world today and will continue impacting it in 2023 and beyond.

Producing Biofuels is Better for the Environment

Biofuels are a renewable, clean-burning source of energy that can be used to replace fossil fuels. When you burn biofuel, you aren’t releasing greenhouse gasses into the air. In fact, when considering the life-cycle carbon footprint of biofuels—from cultivation through production and use—they actually emit fewer greenhouse gasses than petroleum or other fossil fuels.

Diesel engines and diesel are used in trucks and heavy equipment like tractors and bulldozers, buses, trains, and ships. Biofuel can be used as an alternative fuel instead of diesel fuel in these vehicles without requiring any modifications to them because it is chemically compatible with petroleum diesel.

Many colleges and universities across the world are heavily invested in research involving biofuels. Even courses are specifically designed to involve their students in either generic or extensive ways. Studying Strayer University’s notebooks will help you realize just that. Students use these notebooks to gain a better understanding of their biology and chemistry lessons. They also use them for research down the line. A quick look at these notebooks will reveal just how invested these universities are in biofuel and other green energy alternatives.

Biofuel is Less Expensive Than Other Petroleum Alternatives

When it comes to cost, biofuels have a distinct advantage over petroleum alternatives. On top of these high prices, consumers are also paying high taxes on their fuel purchases due to their carbon emissions being harmful to the environment and society at large.

Coal is another fossil fuel whose prices fluctuate depending on how much demand there is for it from utilities across North America. Coal-produced energy is also costly. Thus, biofuel needs to be embraced by the masses if they want to limit their spending on fossil fuels.

Biofuel Consumption Increases the Gross Domestic Product

The more fuel you use, the more money you spend on that fuel. When you buy biofuel, your purchase creates jobs in areas like agriculture, transportation, and distribution. This creates a ripple effect throughout your local economy as well as in other sectors around the world.

In addition to this direct benefit, governments also benefit from rising GDPs because they can collect taxes on these sales. Consumers will also have more disposable income to spend on goods and services outside of their normal budgets, increasing economic activity worldwide.

Biofuel Can be Better for Your Engine’s Lifespan

In addition to being better for the environment, biofuel can also be better for your engine’s lifespan. The reason is that the different chemicals in biofuels react differently with your engine. As a result, you may need a different blend of biofuel than your car is used to running on. This means that you should consult with an auto mechanic before using any kind of alternative fuel in your vehicle.

Biofuels Are More Efficient Than Gasoline and Diesel

Biofuels are more efficient than petroleum fuels. They have a higher energy density than conventional gasoline and diesel, which means you can get more power out of a smaller amount of fuel. This is especially important for cars that rely on internal combustion engines (ICE), which are the standard vehicle in many parts of the world.

impact of biofuels on air quality

Biofuels are increasingly being used to power vehicles around the world

The majority of ICEs cannot burn biofuel blends directly. They require some kind of modification first. However, they can use it by converting existing gasoline or diesel engines with special hardware.

Biofuels Improve Air Quality in Urban Areas

Biofuels reduce the amount of particulate matter (PM), carbon monoxide (CO), and nitrogen oxides (NOx) in urban areas. PM is a collection of solid particles that get into the air and cause health problems like lung cancer and asthma. CO causes smog that can irritate your eyes and make it hard to breathe normally. NOx gasses contribute to the formation of ozone, another pollutant that is harmful to human health.

The concentration of all these gasses and particles in biofuel emissions is low. Thus, vehicles running on biofuel do not heavily harm the air quality.

Bottom Line

Biofuel is the future of clean energy. The sooner we understand this fact and accept biofuel, the better it is for us and this planet.

Challenges in Hazardous Medical Waste Management

  By | | , ,
6 Comments

Medical waste management is a concern of healthcare facilities all over the world; about 10-20% of the facility’s budget every year is spent on waste disposal. According to the WHO, about 85% of the total amount of generated waste is non hazardous but the remaining 15% is considered infectious, toxic or radioactive. While non-hazardous medical waste poses less problems, the risks and challenges of hazardous medical waste management must be considered carefully, since incineration or open burning of hazardous medical waste can result in emissions of dangerous pollutants such as dioxins and furans. If you’ve been injured due to hazardous waste emissions, contact Pittsburgh Injury Lawyers, P.C. to learn your legal options.

medical-waste-management

For this reason, measures must be taken to ensure safe disposal of hazardous medical waste waste in order to prevent negative impact on the environment or biological hazards, especially in developing countries.

1. Health Risks

Biologically hazardous waste can be a source of infection due to the harmful microorganisms it contains; the most exposed are hospital patients, hospital staff, health workers. However, the situation is potentially harmful for the general public as well. The risks include chemical burns, air pollution, radiation burns and toxic exposure to harmful pharmaceutical products and substances, such as mercury or dioxins, especially during the process of waste incineration.

Other risks can also derive from the incorrect disposal of needles and syringes; worldwide, it is estimated that, every year, about 16 billion infections are administered. Unfortunately, not all needles are safely eliminated, creating risk of infection but also the possibility of unintentional reuse. Even though this risk has decreased in recent years, unsafe infections are still responsible for many new cases of HIV, hepatitis B and hepatitis C.

2. Environmental Impacts

Incorrect disposal of untreated healthcare waste can contaminate drinking and ground water in landfill, and also release dangerous chemical substances in the environment. Deficient waste incineration can also release hazardous pollutants in the air, and generate dioxins and furans, substances which have been linked to cancer and other adverse health conditions. Heavy metals, if incinerated, can lead to the diffusion of toxic metals in the environment.

The Way Forward

There is still a long way to go in order to ensure safe disposal of hazardous healthcare waste. A joint WHO/UNICEF assessment conducted in 2015 found that only 58% of analyzed facilities over 24 countries had appropriate medical waste disposal systems in place.

Strategies to improve healthcare waste segregation is an essential step in medical waste management

In the workplace, it is important to raise awareness and promote self-practices. Training in the areas of infection control and clinical waste management is important in order to maintain a clean, safe environment for patients and staff alike. Specialized industrial cleaning can also be effective in reducing risk of infection.

It is also essential to develop safe methods and technologies of treating hazardous medical waste, as opposed to medical waste incineration, which has already been shown to be ineffective and dangerous. Alternatives to incineration, such as microwaving or autoclaving, greatly reduce the release of hazardous emissions.

Finally, developing global strategies and systems to improve healthcare waste segregation is another essential step; since only about 15% of clinical waste is hazardous, treatment and disposal costs could be reduced significantly with proper segregation practices. Furthermore, these practices also reduce risks of infections for those workers who handle clinical waste.

Combined Heat and Power Systems in the Biomass Industry

  By | | , ,
11 Comments

Combined heat and power systems in the biomass industry means the simultaneous generation of multiple forms of useful energy (usually mechanical and thermal) from biomass resources in a single, integrated system. In a conventional electricity generation systems, about 35% of the energy potential contained in the fuel is converted on average into electricity, whilst the rest is lost as waste heat. CHP systems use both electricity and heat and therefore can achieve an efficiency of up to 90%.

CHP technologies are well suited for sustainable development projects because they are socio-economically attractive and technologically mature and reliable. In developing countries, cogeneration can easily be integrated in many industries, especially agriculture and food processing, taking advantage of the biomass residues of the production process. This has the dual benefits of lowering fuel costs and solving waste disposal issues.

CHP systems consist of a number of individual components—prime mover (heat engine), generator, heat recovery, and electrical interconnection—configured into an integrated whole. Prime movers for CHP units include reciprocating engines, combustion or gas turbines, steam turbines, microturbines, and fuel cells.

A typical CHP system provides:

  • Distributed generation of electrical and/or mechanical power.
  • Waste-heat recovery for heating, cooling, or process applications.
  • Seamless system integration for a variety of technologies, thermal applications, and fuel types.

The success of any biomass-fuelled CHP plant is heavily dependent on the availability of a suitable biomass feedstock freely available in urban and rural areas.

Rural Resources Urban Resources
Forest residues Urban wood waste
Wood wastes Municipal solid wastes
Crop residues Agro-industrial wastes
Energy crops Food processing residues
Animal manure Sewage

Technology Options

Reciprocating or internal combustion engines (ICEs) are among the most widely used prime movers to power small electricity generators. Advantages include large variations in the size range available, fast start-up, good efficiencies under partial load efficiency, reliability, and long life.

Steam turbines are the most commonly employed prime movers for large power outputs. Steam at lower pressure is extracted from the steam turbine and used directly or is converted to other forms of thermal energy. System efficiencies can vary between 15 and 35% depending on the steam parameters.

Co-firing of biomass with coal and other fossil fuels can provide a short-term, low-risk, low-cost option for producing renewable energy while simultaneously reducing the use of fossil fuels. Biomass can typically provide between 3 and 15 percent of the input energy into the power plant. Most forms of biomass are suitable for co-firing.

Steam engines are also proven technology but suited mainly for constant speed operation in industrial environments. Steam engines are available in different sizes ranging from a few kW to more than 1 MWe.

A gas turbine system requires landfill gas, biogas, or a biomass gasifier to produce the gas for the turbine. This biogas must be carefully filtered of particulate matter to avoid damaging the blades of the gas turbine.

Stirling engines utilize any source of heat provided that it is of sufficiently high temperature. A wide variety of heat sources can be used but the Stirling engine is particularly well-suited to biomass fuels. Stirling engines are available in the 0.5 to 150 kWe range and a number of companies are working on its further development.

A micro-turbine recovers part of the exhaust heat for preheating the combustion air and hence increases overall efficiency to around 20-30%. Several competing manufacturers are developing units in the 25-250kWe range. Advantages of micro-turbines include compact and light weight design, a fairly wide size range due to modularity, and low noise levels.

Fuel cells are electrochemical devices in which hydrogen-rich fuel produces heat and power. Hydrogen can be produced from a wide range of renewable and non-renewable sources. A future high temperature fuel cell burning biomass might be able to achieve greater than 50% efficiency.

Here’s What To Expect With Your First Environmental Inspection

An environmental inspection gives the organization crucial information that will help it create a successful program for ongoing environmental improvement. All investigations, from on-site visits to data gathering and analysis, are taken into account to control their environmental impact. It also assists in finding ways to improve waste management, and eventually comply with environmental laws. The process may seem daunting if you are a business owner undergoing an environmental inspection for the first time. Here is a brief guide to the entire environmental inspection process to calm your nerves.

environmental inspection process

Steps in Environmental Inspection

Environmental inspections cover various domains. Although the procedure may differ slightly, the standard process of an environmental inspection follows 7 steps. These are:

1. Planning

  • Defining The Context

It’s crucial to establish the inspection plan’s context. According to the mission’s goals, statutory tasks, and competencies, the inspection authorities determine the mission’s scope according to the context. Setting the backdrop is crucial to focus on the dangers that must be examined.

  • Establishing Priorities

Conducting a risk analysis is crucial to preparing for an environmental inspection. Priorities are established by determining the hazards associated with the various installations and activities at the inspected facility. The risk level is then categorized into high, medium, and low risk.

  • Settings Goals And Objectives

The inspection’s goals can be decided upon once the priorities have been established. Performance indicators should be used to keep track of the output and outcomes to determine whether these goals can and will be met. Compliance with relevant environmental regulatory requirements is always one of the goals.

  • Planning And Review

Based on the preceding processes, the inspection plan and schedule are established. The strategy, the objectives, and the pertinent conditions under which the inspection is to be conducted are all covered in depth in the plan. On the other side, the schedule contains the logistical information on the inspection and the appointed inspector(s).

2. Framework And Protocols

The framework for the inspection activities is established in this step. It is crucial to guarantee that the investigation will be conducted efficiently, expertly, and consistently. At this time, working guidelines and protocols are created.

3. Execution

Activities designed to confirm compliance are included  to carry out the inspection efficiently, and in accordance with the protocols established in the earlier steps. Everything is carried out in accordance with the protocols established in the earlier steps. A searchable database contains all the details of the inspection activities, findings, and follow-ups. The inspector(s) conclude their inquiry by issuing a report in which all the information and earlier reports are examined and analyzed.

4. Performance Analysis

Performance analysis enables the inspecting authority to determine whether goals and targets have been met and to report either internally or externally. Performance indicators show which methods and tactics are most effective in ensuring compliance and whether the inspection authority is carrying out its duties. The data provided in this stage can be used to analyze the inspection plan and potentially generate reports for usage by outside parties.

How Can UAV Benefit Inspections?

Drone technology offers access and insight that some individuals are unable to obtain on their own. There are several ways that UAVs benefit the environment. Besides wildlife conservation and reporting climate change, drones are quite helpful for gathering inspection data. The ability to gather data provides the opportunity to make more informed decisions. Drones primarily record, monitor, and take images of what is going on in the environment. Several organizations, like soar consulting, are now actively utilizing UAV technologies for environmental inspection.

Final Thoughts

Conducting an environmental inspection can reveal the precise state of an organization’s compliance with environmental laws. This enables proactive businesses to anticipate new regulations and set up businesses in accordance with the established regulations and compliances.

Is Tire Recycling Dangerous?

Not too long ago, mountains of old tires were to be found in virtually every town and city’s landfill, and toxic tire fires that would sometimes take months to subside were a common occurrence. Today, these tire piles are a rarity, and thankfully, so are the fires that used to go with them.

We have largely to thank the combined initiatives of scientists, entrepreneurs, and legislators from banishing unsightly these unsightly tire piles from the landscape. Today you’re more likely to see old tires in your yoga mat or the asphalt you drive on than in ugly piles that you can see from the distance.

However, there have been questions about the widespread use of tire chips, especially in playgrounds, as mulch, and as repurposed water containers for agriculture and livestock.

These concerns are quite understandable, as we are in direct contact with tire chips when they are used in the first two applications. When used for agriculture and livestock, there seems to be a distinct and logical risk that any toxins that are released in those applications may eventually end up in our bodies.

Recycled tire products are safe for consumers

Provided that you are not the one processing the tires yourself (more on that later), there is an extremely low toxicity risk in tire chips. A typical tire chip is made from old tires, which means that they have already off-gassed much of their volatile organic compounds (VOC’s).  New tires emit a good amount of VOC’s, which you can readily detect because of the unique new tire smell.

Many of these compounds have been linked to cancer. However, decades of research and uncontrolled use of old tires in different applications through the 20th century seem to strongly indicate that unless you are actually involved in producing or processing tires, your risks are quite low due to the low dosage of chemicals a typical consumer can expect. It’s the doses that makes a chemical toxic, and in the case of old tires where most tire chips are derived, the risk is negligible.

However, working in an environment where you can actually smell the “new tire scent” constantly can be a significant risk. By analogy, a bartender will be fine if they have a drink with one customer. But if they drink with every single customer that comes by every night, they’re in serious trouble.

Recycling large volumes of tires can be problematic

Unless you constantly work with tires, the risk is quite minimal. You can and should feel free to recycle or repurpose any tires you have around your house or yard into furniture, tire swings, planters, or pet beds. However, if you’re thinking of recycling dozens of tires a week, you should reconsider, as the particulate dust from carving up or shredding old tires can also be a risk over time if you don’t have the right equipment or safety gear.

Improper tire recycling can also heighten your exposure to dangerous chemicals in the tires, especially when they are subjected to the heat of a grinder or shredder that is not specifically meant for tire recycling. This can expose you to high levels of carcinogenic VOCs without you realizing it.

If you need to safely dispose of a high volume of tires, or tires that are difficult to recycle, such as those on tractors and OTR vehicles, be sure to contact a professional recycler like Western Tire Recyclers.

The Impact of Clogged Air Filters On HVAC Energy Consumption

  By | | , ,

As soon as the chill begins to set in with fall, the need for indoor heating starts to push electricity bills up significantly with each passing month. This continues until winter finally arrives and skyrockets electricity bills to ridiculous amounts. This is pretty much what happens in summer too if you happen to live in Texas, Florida or any of the other hot states.

In both situations though, it’s the HVAC system that consumes all the energy, which is not exactly unexpected. What most of us don’t realize is that it’s most likely those clogged air filters that are making the HVAC waste more energy than it should need. Let’s talk about the impact of clogged air filters on HVAC energy consumption

How Do Clogged Filters Affect Your HVAC System?

Before we can discuss how clogged filters affect electricity bills, it is important to understand how clogged filters affect HVAC units in the first place.

The role of an air filter is simple enough; it stops as much of the air impurities as possible from entering and circulating in the indoor environment. After a while, all that dirt, dust, debris, etc., that the filter prevented from getting in begins to congeal together, slowly closing off the airways.

Once the accumulated gunk becomes heavy enough, the HVAC system has to work extra hard to push air past these narrow airways. This is where the problem lies, as a number of negative effects from the increased exertion and dirty filters are seen.

The Effects of Extra Load on HVAC Units

Given that an HVAC system isn’t equipped to handle all that extra load on a regular basis, a number of negative impacts are seen as a result of clogged air filters.

  • The unit begins to consume more power, to be able to push air past the dirty air filters
  • The increased power consumption becomes evident, as energy bills surge in direct proportion
  • Excess load decreases the potential lifetime of an HVAC unit
  • The heat exchange mechanism can overheat and short-circuit
  • The cooling coil may freeze in absence of sufficient airflow for dissipating condensation during summer
  • Breakdowns become more common, further adding to the maintenance expenses
  • Both the heating and cooling capacities of the unit suffers; slower and less effective heating/cooling
  • Since the air is pushed through the gunk with force, it circulates all the dispersed pollutants throughout the house

How to Know When Your HVAC System Needs a Filter Change?

Some of the signs are pretty obvious, but you should act before they become too obvious and your unit breaks down in the middle of January! It can get a little costly to change air filters on a regular basis for sure, so try to get them from discountfilterstore.com.

Go through the following and it should provide a decent guide towards detecting the need for a HVAC filter change before the problems get too serious.

  • It has been more than three months since your last filter change
  • The filters are starting to look grey or develop spots
  • Increase in indoor dust accumulation
  • Increase in allergic reactions such as sneezing, skin rashes, etc.
  • Heating/cooling seems to be taking a lot longer than expected
  • Heating/cooling isn’t as effective as before

Air filters serve the vital function of keeping the indoor environment fresh and healthy for everyone, but those same filters can also become the cause for health and financial problems unless they are changed in time. As long as you keep track of the change cycle though, none of what we discussed should be a cause for concern.
