Air Conditioning Question: Why Are Clean Filters So Important for Efficiency?

Your air conditioner cost money to operate – 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

Did you know that you can lower your air conditioner’s energy use by up to 15 percent by just keeping your filters clean? While that might seem surprising, it actually makes a lot of sense when you consider how the filter works.

The filter on your AC captures dust and debris that is circulated through your system. If you didn’t have a filter at all, the dust and dirt would not only cause problems with some of the mechanical parts of your AC but also reduce your indoor air quality. However, when a filter is clogged, your HVAC system has to work harder to draw air in. Your motor will need more electricity for the same amount of cooling.

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.
