To ensure efficient and safe HVAC system operation, it's important to perform routine maintenance. Dirt and neglect are the top causes of heating and cooling system inefficiency and failure. We provide pre-season tune-ups before each cooling and heating season. In order to test and perform the maintenance on your system it must be residential and in good working order. To schedule your furnace or A/C tune-up Mon.- Fri., 8am- 5pm. call 614-678-6344 NOW.
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.
Just wanted to thank you for taking such good care of our AC this spring, and we look forward to your fall maintenance special to schedule for our furnace. We are very pleased with the service and will reccomend your company to our friends and family.
