How Often Do You Change Your HVAC Air Filter?

As much as we talk about professional air conditioning maintenance, one point we can’t stress enough is that there is a maintenance task that you can and should perform on your own. That is changing or cleaning the air filter in your HVAC system on a regular basis.

Your HVAC system’s air filter protects the cabinet which houses your air conditioner and furnace, or heat pump. It prevents dust, dirt, and other debris from entering the system and your home via the return air vents from creating damage. But if your air filter is ignored, then it can and will become clogged, resulting in an obstruction to your airflow and an air conditioning system that’s both inefficient and in danger of breaking down prematurely. There are a few factors that will determine how often you should change or clean your air filter, including what type of filter it is. Keep reading to learn more.

Permanent Filters

As a rule, we do not recommend that you invest in a permanent air filter. These are not as effective at actually filtering the air as temporary filters are. Additionally, these types of air filters can develop harmful and inconvenient mold and mildew over time. That being said, if you do have a permanent filter, you’ll want to have it removed and cleaned gently with a garden hose every 1–2 months.

Panel Filters

Of all the types of air filters, the panel variety is the least expensive, and thus typically the most popular. Though still efficient, they do have less powerful filtration levels than most pleated filters, and as a result need frequent changing—typically once a month. Make sure that you use a permanent marker to note the last time you changed your filter in order to avoid delaying this for too long.

Pleated Filters

Pleated filters are a bit more costly than their panel counterparts. This is largely because they are constructed of polyester rather than fiberglass. As a result, they are more powerful at air filtration. Be aware, you don’t want your air filter to be too powerful as it may restrict airflow. This typically only needs to be replaced every 3–6 months. Be sure to check on your pleated air filter more often than this, however, just to check its progression.
