A clean air filter is vital to the performance of your home’s heating and cooling system. As air flows to and from your system, the air filter traps dust, dust mites, pollen, pet dander and other particles, removing them from your air. Over time, these particles build up on the filter, reducing its effectiveness.

Check the filter monthly. If it appears dirty, change it. At a minimum, the filter should be changed every three months.

Dirty air filters:

  • Affect the air quality in your home.
  • Restrict the air flow into your system, making the fan motor work harder, consuming more energy and costing you more money to stay comfortable.
  • Forcing the motor to work harder will shorten the life of the motor again costing you more money to have the motor replaced prematurely.
  • Reduced air flow across your furnace will cause the temperature of the furnace to rise which will put more stress on the metal heat exchanger and could cause it to crack and even leak dangerous Carbon Monoxide into your home.

There are many types of air filters available. Using the correct size and type of filter for your system will provide optimum results. The most efficient filters may not be the best option for your system. Today’s highly-efficient filters cause an increase in the level of airflow resistance, which can restrict airflow and cause damage to older heating and cooling systems. Consult your system’s operating manual for recommended filters.Here at Acosta Heating & Cooling, we’re happy to answer your questions about air filters, or to offer expert advice regarding your heating and cooling needs.
