Homeownership is exciting and comes with maintenance responsibilities, like cleaning gutters, mowing the lawn, and cleaning or change HVAC filter. The later is what we are going to discuss here today.
The general recommendation to clean or change air conditioning filter or HVAC filter is once a month, and many homeowners will replace the batteries in their smoke detectors at the same time. This regular maintenance step will ensure that the air conditioner or HVAC system is working at in top condition without having to work harder than necessary.

While changing or cleaning the AC or HVAC filter is one of the simplest things you can do, if you have never done it before, review the instructions in the owner’s manual first. This should tell you what size and shape of filter to purchase – and there are many and it does make a difference. If your home is an older home and there is not manufacture manual handy, you will be able to see what shape, size, and type of filter it requires when you remove the current one.
Also, if you do not follow the recommendations given by the manufacturer, you could be voiding any warranty or any HVAC warranty plans that may have come with the unit and your home. The owner’s manual should also advise you how to change the HVAC filter, but if not, we offer the following general instructions:
There are reusable filters for air conditioners and HVAC system these days. They are more expensive to purchase, but they are reusable because they can be washed and returned to the system, thus getting your money’s worth.
A window AC unit filter is much easier to get to than an HVAC system. You simply, but carefully, pull off the front grill and the filter will either snap out or is pulled up or down. Rinse it with nothing but clear water in the bathtub, kitchen sink, or outside with a water house. Allow it to stand up right where it can dry then return it, following the same steps in reverse.
After you have removed the filter through the access panel as instructed above, simply run clear water through it in the bathtub, kitchen sink, or in the yard with a water hose. You want the water to have force, but not too strong as to rip a hole through it. Then set it someplace where it can dry, and then return it to the HVAC system.
If you have a home warranty plan, like those offered by Liberty Home Guard, check with your policy to see if filter changing or cleaning is covered by the policy before you begin. If not, you should inquire how you can get full HVAC coverage that does offer this service.
