Subscribe to our RSS Feed Change the Furnace Filter Regularly and Enjoy Efficient Heating and Cooling

Saturday, March 14, 2015

The furnace filter in your HVAC system is designed to remove dust, hair and other debris from the air supply before it enters the furnace. This protects the blower fan, heating coils and other sensitive components from damage. Changing the furnace filter is an easy job that not only helps protect your system, but also keeps it running efficiently and improves your indoor air quality.

The Furnace Filter's Job

Most furnace filters are designed to protect the internal components of HVAC systems from dust accumulation that can cause unnecessary friction, overheating and other system damage. Higher quality filters also help to remove airborne particles such as mold spores, dust, pollen and pet dander from the conditioned air, making your indoor air healthier, especially for those with asthma, allergies or other breathing difficulties.

When the furnace filter is dirty or clogged, it will reduce the amount of harmful particles removed from the air and force your HVAC system to work harder to keep your home at your preferred temperature. With the increased workload, the heating and cooling system will require more energy than normal, increasing utility bills. It will likely need more frequent maintenance as well.

Changing the Furnace Filter

Disposable filters usually last about one or two months before they need to be replaced, and reusable filters can often go from two to four months between cleanings. It's a good idea to check the air filter monthly to make sure it's in good condition.

Before changing the furnace filter, shut off the power to the HVAC system. Locate the access panel for the filter, usually found near the air intake for the blower fan, and open it. Refer to the owner's manual of the HVAC system, if necessary. Slide the old filter out and replace it with a new one or, if it's reusable, clean it and let it dry completely before reinstalling it.
