Many homeowners wonder how often they should change their home air conditioning (AC) filters and how to do it? This article can help answer these questions so that you know when and how to do these tasks.
The easy answer: It depends. Answer these questions first before you decide to change your AC filter and always consult a professional for your AC repair and AC service needs.
There are seemingly an infinite number of filter size options. The sizes and types of AC filters on the market can vary. Call the manufacturer or your favorite expert tech to learn the “right” air filter for your AC system. Visit your AC manufacturer’s website to learn where you can buy the air filters your AC system uses or ask your tech expert for the size you need. You could also remove the one you now use and look on the frame for the labeled dimensions (width, depth, and height).
Many people do not think about their AC system until it doesn’t work. You only need to take these three simple steps to improve the efficiency of your AC by 5 to 15%, by changing clogged filters.
Older systems typically use fiberglass air filters. You should replace these regularly, around every 30 days. Newer systems often use pleated filters, also rectangular with a depth of about one inch. You should replace these about every 90 days if you have no allergies, but AC pros typically recommend every 45 days for max efficiency.
Be sure to replace them with the right size and type of air filter. If your AC was working properly, you could remove the filter and buy one that is identical to it. If you have a “media filter” you’ll only need to replace it every 6 to 8 months. These look like pleated filters, but last longer.
It is vital that you choose the right filter for your AC system. The key is to change them (or clean them) regularly. Always replace a clogged filter with a new, clean one. If you suffer with allergies or have a pet, change filters more often than the “rules of thumb” appearing earlier in this article.
