A few different types of HVAC systems have different ways to change their HVAC filter. There are a few tips that you will want to follow before you change out your HVAC filter. Changing your HVAC filter often is recommended for cleaner air and decreases the chance of pollutants in the air. This way, you’ll have safe air and a clean environment.
Tips for Changing Your HVAC Filter
There are certain things that are good to know before you start the process of changing your air filter.
1) Find your Air Filter Locations
It is essential to know where your HVAC systems are in your house to know where you should change your air filters. Also, if you have different types of air filters, this is good to note because each air filter will have to be changed differently. So, getting acquainted with the locations is recommended.
2) Correct Size
Each air filter has different sizing. To get the best measurements for each air filter in your home, it is best to measure the vents that the air filters go in and then buy the air filters that will fit your vent. You can also look at the last air filter in your HVAC system and go based on that size. Sometimes though, the previous air filter may not be the right size, so measuring will be more accurate. If you do not have the correct size, you could miss harmful pollutants coming into your home, which is not desirable.
3) Place the Filter Correctly
This tip is essential because if you do not place your air filter correctly, more pollutants may be pushed through the vent, causing your HVAC system to work harder. When your HVAC system works harder, you end up paying more on your energy bill, and your air is not clean. So, placing the air filter correctly is crucial.
