How to Change Your Air Filter, And Why You Must Do So

For the most part, HVAC system maintenance is something that must be completed by qualified professionals. What the average homeowner can and should do, however, is change the air filter as needed. Generally, this should be done once a month or every three months. Refer to your owner’s manual and the type of air filter that you are using to figure out which is appropriate in your case. 

How Do I Change the Air Filter?

Changing an air filter is simple, provided that you take the time to familiarize yourself with the proper steps. First, be sure you are replacing your air filter with the right make and model. Once you’ve determined which air filter to use and have a procured a replacement, you are ready to swap it out. Turn your HVAC system off, as this will protect you from potential safety risks. If you don’t know how to shut off your system, shut off the circuit breaker that the system is on. It should have its own designated circuit.

Remove the old air filter from its slot. Take your new air filter, and be sure to slide it in so that it is facing the right way. There will most likely be arrows or colors in order to differentiate the front from the back. You need to have it facing the right way if it is to function properly.

You need to change your air filter regularly to protect your HVAC system and its efficiency. Yes, the air filter can help to reduce the amount of pollutants blown throughout your home, but maintaining high indoor air quality is not its primary function. It prevents the buildup of pollutants within the system itself. If you let your air filter sit in your system too long, it can clog up, increasing airflow resistance and putting unnecessary strain on your system. This also will negatively affect efficiency levels.
