Changing the filter during a Furnace maintenance

Furnace Maintenance

Furnace efficiency and safety

It is essential to perform routine maintenance on your furnace to ensure it is working efficiently and safely. Dirt and neglect are the top causes of heating system inefficiency and failure. Having regular maintenance performed on your furnace in the fall will ease the wear and tear on your system, prolonging the lifespan and saving you money by not having to replace it before its time. Your furnace will take less energy to run, and this could lower your utility bill. 

Yearly tune-up

We provide a pre-season tune-up for your furnace in the fall before the cold season starts to make sure it will work when you need it most. For our certified technician to perform the maintenance on your furnace, it must be residential and in good working order.

Customer Testimonial

I called KNOW Heating last fall to check my furnace and perform a thorough maintenance and saved 50% off their regular in-season price. When it got cold my furnace came on and ran all winter without any problems, the technician even gave me tips and showed me how to change the filter. Thank you KNOW.
