1. Clean or replace your filter
A furnace filter will remove all kinds of particulates, including dust, dust mites, pollen, pet dander, bacteria, spores, and more.
2. Make sure blower motor is functioning correctly
The furnace blower motor drives the fan that provides air movement for the furnace.
3. Reduce home’s heating load
Any weakness in the structural shell of your home allows cold winter air to seep in and warm air to leak out. Sealing up your home’s envelope reduces heat load, which is the amount of heat needed to keep your house comfortably warm.
4. Make sure all household vents are free
In order for your heating system to work properly, the air in your house must circulate completely throughout the system.
5. For gas furnaces, verify the exhaust flue to the outside is clear
There are three main reasons an exhaust flue needs regular attention: carbon monoxide, nitrogen dioxide, and sulfur dioxide. These three components can be found in the fumes from your furnace, especially if it hasn’t been serviced in awhile.
6. Clean your heating systems vents and ductwork
As with all systems, your entire heating and cooling system needs to be cleaned and regularly maintained to ensure it’s in good operating condition.
