An air filter is designed to remove impurities from the air like dust, pollen, pet dander, and mold spores, amongst others. When a filter is not performing properly, it does the exact opposite, by leaving the impurities in the air that could possibly lead to health problems for the occupants of the home. If a unit fails, the first initial reaction is that something is wrong with the air filter. An air filter must be cleaned and/or replaced as needed, due to the fact that dirty air filters may restrict the air flow and ultimately cause your system to burn out. In other instances, an air filter may not be the problem, the problem may be leaks in your ductwork on the return side of the HVAC system. If your ductwork has leaks, it reduces the efficiency of your unit and will effect your energy costs. Leaks cause your home to receive more air than it should, this can lead to the build up of dust and that can possibly lead to failure of the unit. A way to make sure your ductwork is sealed tight is to do a pressure test. This test will measure the air tightness of the air distribution system and will provide you with answers on whether or not your ductwork is sealed properly.
Other reasons for unit failure:
- dirty blades on the blower fan
- a fire damper that is stuck closed or partial closed
- collapsed sections of the flex duct
- insulation that has become loose in the ductwork
- dirt build-up on coils
To prevent your unit from failing, here are a few maintenance tips:
- change your filter regularly
- have a yearly check up on your HVAC equipment to ensure everything is working properly
- seal heating and cooling ducts
