HVAC Air Filters Are Your Best Friend And Worst Enemy

air filters

You probably know that your air filters filter the air in your home. Whether you have a central air conditioning system or a ductless air conditioning system, the air filters in your system keep the air clean.

When your air conditioning system kicks in, it immediately starts sucking air into the cold air return, pulling it across the air handler. After a quick pass, that air is pushed out through the ducts, to be collected again by the cold air return and put through the system again. In ductless air conditioning systems, the process is very similar except as you can tell by the name there is no ductwork involved.

Change Your Air Filters

As your air filter picks up more dust, hair and another airborne particulate, it gets harder for the air handler to suck air into the system. Eventually, air filters can get so dirty that there’s almost no airflow and, therefore, no climate control.

Surprise, this can lead to a massive drop in the efficiency of your central air conditioning system or your ductless air conditioning system. Strangely enough, most homeowners aren’t ever told how often to change their filters, and on top of that, the three-month estimate on a lot of filter packages is a ridiculous overestimation of how long that filter will last.

Listen To HVAC & Air Filter Experts

HVAC professionals recommend you check your filters at least once a month and replace them any time they start to look dirty. The cleaner your filter is, the better it will work and the more efficient your entire system will be. You will also have much cleaner air in your home, which is important for the health of you and your family.

If it’s been a while since you changed the filter and the system’s still kicking on, just blowing the wrong temperature, start at the filter. Change it, even if it’s only discoloured. This can indicate that the tiny passages in the paper are clogged.
