Replacing your air conditioning filter is one of the most important steps you can take to ensure optimal system performance and cleaner air in your home. It can be found in the air, and when deactivated, it prevents dust and sand from entering the system. If you have an electronic media filter, you don't need to replace it every 1-3 months, but rather wait 6 months to a year before doing so. It's important to replace it with the exact filter of the model, which may require ordering it on the brand's website.
Dirty air conditioner or oven filters are the number one problem when forced air heating and cooling systems don't work well. It may be more convenient to buy replaceable filters if you don't want to take the time to wash the filter. Replacing a clogged or dirty filter can help make your home more comfortable because air flows freely through the system. Some may accept air filters with higher ratings, but if it goes up too high, you can introduce an airflow restriction that reduces efficiency as much as a dirty air filter does.
It's also a good idea to check the filter every month and change it when it's dirty and when the summer season heats up, and use the air conditioner more often. While you need to know how to change an air filter, professional HVAC maintenance is a good idea, even when you're keeping up with regular air filter changes. Clean permanent filters or replace disposable filters in the forced air system every six months, unless they become clogged with dust first. If you perform proper filter maintenance and your air conditioner or heater breaks down, your home warranty plan will repair or replace your HVAC unit. Not changing the filter can mean you'll face repair, higher energy bills, and a shorter air conditioner life.
