after day, your high-efficiency HVAC system dutifully provides excellent and efficient home comfort. However, something as simple as a dirty air filter can bring that all to a halt.

Clogged Air Filters Bring Trouble

Your home’s central cooling and heating systems rely on a steady, balanced flow of air to operate at peak efficiency. The air filter’s main role is to trap various types of airborne particles before they find their way into the air handler and ducts. As the filter traps more airborne pollutants, this reduces the amount of air that’s able to pass through the filtration media.

Eventually, the air filter becomes so clogged that little to no air can pass through at all. Some of the airflow may even bypass the filter, causing dust and other debris to collect on the blower fan blades and the interior of the ductwork. Pollen, mold spores and other airborne irritants are allowed to circulate and proliferate throughout conditioned spaces.

Meanwhile, the blower fan has to work harder to compensate, wasting precious energy in the process. Eventually, the blower motor will burn itself out. The evaporator coils may also freeze over due to the lack of air being blown over the coils and an overabundance of moisture in what little air flow is present.

Going with the Flow

Getting rid of that dirty air filter does wonders for restoring your HVAC system’s airflow, with the welcome side effect of improving your home’s indoor air quality. It’s a good idea to change or clean your air filter every 30 to 90 days, depending on the manufacturer’s suggestions and other factors such as how much the system is operating and the number of pets you possibly own. Replacing those dirty filters also will help lower energy consumption and your utility bills.
