Air conditioners cost a lot of money to operate in Tucson – even more when they don’t work at 100% efficiency. So, it is important to perform the various regular maintenance tasks that ensure the system uses as little electricity as possible. The first thing on your list (and the easiest) is cleaning those filters.
Keeping Filters Clean
The Department of Energy’s Energy Savers website states that you can reduce your air conditioner’s energy consumption by as much as 15% simply by keeping the air filters clean. Why do they matter so much? Consider the nature of a filter.
The filter on your AC unit is designed to capture any dust, debris and sediment in the air supply. If that dust and sediment was allowed in, not only would it gum up the mechanical workings of the device, it would get into your ductwork and reduce the air quality of your home. So, filters are used to capture such things. However, when a filter gets clogged, the system must work harder to draw the air in. As it works harder, the motor turns faster and more electricity is used.
It takes very little to clog the filter of an AC unit, especially if it is running 24 hours a day for two or three months out of the year. So, it’s best to check your filters once every 30 days regardless of what type of filter you are using.
Which Filters to Check
The main filter on your AC unit should be checked along with any air handler filters and any air cleaner filters you have installed in your system. Another thing to consider is the condition of your home and the area around your outdoor condenser. If you have pets, lots of plants or your condenser is located in a dusty area, you may need to check and change those filters even more often.
Most filters are located along the return length of the ductwork – sometimes in ceiling ducts and walls, though they may also be located in your furnace’s air handler or inside the air conditioning unit. If you have window units or mini splits, the filters are frequently in the unit.
Clean air filters are important for your health, your wallet and the longevity of your AC system. Stay on top of them and you will save money in more ways than you might expect.
