Understanding the Impact of Clogged Air Filters On Energy Consumption

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 filters that are making the HVAC waste more energy than it should need.

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 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 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.

Saving Energy and Money With Effective Heating and Air Conditioning

Did you know that heating and air conditioning can make up for half of your total energy bill? That’s a lot of money and a lot of energy use. If your heating and air aren’t working properly they can’t effectively use that energy and that costs you money and sends more greenhouse gases into the environment. Below we will list a few ways you can keep your energy bill low and your heating and air systems running smoothly and efficiently.

Limit Use

Use the seasons to your advantage and limit your use of heating and AC. Close your blinds in the summer to keep the sun from working against your air conditioning and open the curtains in the winter time to have the sun help your heating.

Consider if your thermostat has a feature that can be set on a timer so you can limit the use of your heating and air conditioner when no one is in the house or at night. These seem like simple things but they can reduce your costs significantly when done regularly.

Regular Maintenance

Don’t forget to do regular maintenance to ensure your HVAC system is working efficiently. Simple things like changing you air filters can make a huge impact on how well your heating and air conditioning runs. Have a professional come at least once a year to check for any problems you may miss and ensure everything is OK.

Your contractor should measure the voltage of your motors and tighten electrical connections. They should also check for drainage that may cause water damage to your home. These regular check ups also ensure your systems are running properly and safely.

Sealing Ducts and Leaks

Ducts are responsible for distributing the air around your home. However, about 20 percent of air is lost through leaks and poorly connected ducts. This means you’ll be pumping up the AC to no affect and losing money in the process.

Sealing leaks that are visible in the attack, crawl space, or basement of your home is as easy as buying a sealant or tape meant for insulating your ducts. Check for and seal any visible leaks or poor connections. If you prefer to stay away from dirty attics or crawl spaces a contractor can easily do this for you as well.

Insulation

Insulating your home can save you up to 10 percent on your annual energy bill and make your home comfortable all year long. The attic is an ideal place to add insulation to your home and when done correctly can save the most money and energy. Also consider your windows and doors.

Heating and cooling can easily escape through old doors and windows making your system inefficient. Have a contractor look at these places in your home and see if they can help insulate your home so it can run comfortably.

These are just a few examples of ways you can make your home more energy efficient thus saving your wallet and giving a little help to the environment. Find a contractor like Empire HVAC that can look at your home and determine the best route for your house. Different systems have different needs and a professional can tell you everything your house needs to keep you comfortable, regardless of weather  conditions.
