Regular Furnace Maintenance
If your furnace is operating at peak efficiency, it will use less energy and cost less to operate. You should have a heating contractor perform a yearly maintenance check on your furnace, venting, and cooling systems to ensure they are operating at peak efficiency. In between those visits, there are some simple do-it-yourself tasks to help keep your system working efficiently:
Change or clean your filter frequently (i.e., every one to two months) during the heating and air-conditioning seasons. A dirty air filter reduces the airflow to the operating equipment and forces it to run longer to heat and cool the house. Using a furnace filter alarm can let you know when the filter needs to be changed. Electronic air cleaner filters also need to be cleaned regularly (every one to two months).
Keep return air grills, hot air registers, radiators, and space heaters/baseboards clear of furniture, rugs, and drapes to allow free movement of air.
You can ensure more heated or cooled air reaches its destination by sealing the seams of accessible furnace ducting with aluminum foil tape.
TIP: Aluminum foil tape outperforms duct tape for this job, as duct tape has a tendency
to dry out.
Insulate all ducts in unheated or cooler spaces with commercial duct insulation – or make your own! Simply wrap the ducts with glass fibre batts, secure lightly with string, cover insulation with plastic, and tape all edges. You’ll be glad to know that making your home more energy efficient doesn’t have to cost a lot of money. There are many easy ways to keep your heating costs down.
