When Did You Last Check Your Filter?
Dirty filters are a frequent source of issues when it comes to your heating and cooling system. Instead of calling an HVAC company first, you may be able to save yourself a little bit of money by checking out your filter.
In the summer, your air conditioner requires the use of your furnace in order to push the air into your home. This means that air is traveling thru your filter, which will cause it to get dirty. Not changing your filter will cause the evaporator coils to freeze up because the air flow is restricted. Not good when your trying to keep cool during these hot Portland, OR days.
In the winter, your heat exchangers will overheat and will shut down, so your house never warms up. The limit switch that is in place as a safeguard could eventually fail, and then your furnace won’t come on at all. With the winter we just had here in Portland, OR not having a properly working furnace can have serious consequences.
If you use a dirty air filter, then the blower fan must work harder to push air thru. This causes more energy use, which will affect your energy bill. Using a dirty filter will also spread any mold or bacteria growing on your filter throughout the house.
So make sure that in-between your annual maintenance’s, you are checking your filter every 2- 3 months, and replace as needed.
