It may also be wise to consider switching to a system that operates on solar or other forms of renewable energy––Providing if it can be afforded.

Here are some ways you can reduce HVAC energy consumption:

Programmable Thermostat to The Rescue

HVAC system design can be made to consume less energy with the help of programmable thermostats.

The DOE recommends reducing room temperature to 15 degrees in winters when you are not home for 8-10 hours. Similarly, they suggest increasing the temperature by around 15 degrees in summers when you are not going to be home for half the day. This will help you save about 15% more energy annually.

The benefit that programmable thermostat gives you is that you won’t have to manually adjust the temperature every day. You can simply program it to change the temperature and save energy. It also has the added plus of operating on a timer so you don’t have to worry about leaving it on throughout the day.

Maintain The Coils Of Your AC Unit

The outdoor unit of the AC can allow dirt and debris to pass through it and gather around the coils and reduce the efficiency of the AC, as a result the unit consumes more energy to keep the room cool.

Keep your outdoor unit clean from dirt, fallen leaves, and other debris to make it work perfectly. If you believe that your outdoor unit needs cleaning, shut it off and use a vacuum to pull out all the dirt.

Inspect Air Filters

Air filters need special attention as they can get blocked due to dirt and debris. They need to be replaced every season as damaged filters put extra pressure on the unit causing energy to be wasted.

Other than this, you should also replace the filters every now and then. This is not a very tough job and you can do it on your own.

Here’s how to do it:

  • Remove the filter and check for debris stuck in the filters.
  • Keep the filters under light to see if it’s able to pass through. If it doesn’t then you will have to wash the filters.
  • Clean the filters with a toothbrush, or another such tool first.
  • Put the filters in soapy water for a few hours, dry and see if the light passes again. If it does then you can re-apply those, otherwise, you may have to change the air filters.

The average life expectancy of air filters is about 2 to 3 months if they aren’t maintained. Otherwise, they can easily run for a year.

Out With The Old, In With The New

HVAC systems can be costly but if you have been using one for more than 10 years now then it’s time to replace it with a modern and an energy efficient HVAC system.
