  • 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.

  • KNOW Heating has done the maintenance on our furnace and air conditioner for the past 2 years and I must say we have not had a problem one with our equipment ever since. It's great not to have to worry about our heating and cooling.
