Replacing your home air conditioner filter is an important part of keeping your HVAC system running smoothly. Not only does it help keep the air in your home clean, but it also helps to keep your system running efficiently. In this article, we'll walk you through the steps of replacing your air conditioner filter, from locating the filter to choosing the right type for your system. When it comes to changing your air filter, ENERGY STAR recommends checking and changing it every month during peak season.
However, if you're not sure how to do it, it's best to ask your HVAC service technician for help. They can show you where the filter is located, how to remove the old one and insert the new one, and which type of filter is best for your system. If you're looking to improve the air quality in your home by eliminating pollen, mold, and other harmful contaminants, you should invest in HEPA filters with a MERV rating of 10 or higher. As for how often you should replace the air conditioner filter, it's recommended that homeowners do so at least twice a year between major seasons.
However, if you use your oven and air conditioner regularly, you may need to replace the filter more often. Pleated or polyester air conditioning filters are the most economical and practical option for most homeowners. When replacing the filter in an air conditioning system, you may need to open a metal panel (marked FILTER) on the front or top of the blower. You can also refer to the owner's guide for information on which type of filter is best for your system.
When reinserting the filter into the housing, make sure the arrow points away from the return and toward the air handler. It's also important to note that if you don't have a regular HVAC service technician to ask how to change an AC filter, you may have neglected other important maintenance tasks as well. A clogged filter can reduce airflow and force the air conditioner compressor or oven heat exchanger to work harder, potentially leading to overheating and breakdowns. If you no longer have the user manual, you can search online for the make and model of your oven and locate the corresponding AC filter.
Check if it is a disposable filter or if it needs to be cleaned and replaced. The edge of the filter should be marked with cleaning instructions, if applicable. Homeowners who are new to AC filter care should understand that AC filters come in different sizes and wattages.
