Just had my 16-year-old Lennox G23Q furnace serviced by Hunter from Knoechel Heating Company and I couldn't be happier! Knoechel installed our furnace in 2000 and have only had to be called for service a few times since then. Hunter was very thorough in checking and cleaning all components and explaining all along the way what he was doing and why. He is very neat, clean, well mannered, personable and competent. I've been happy with this company and the Technicians who have been sent to our home from the very beginning, and nothing, thank goodness, has changed. I recommend Knoechel Heating Company so highly that I will state here and now that when we need a new system I will be calling them!

Jason came out and identified the new HVAC system that we needed after listening to us and inspecting the current system. He explained the exact work that would be performed and identified everything that would be installed. The price quoted for the work was an honest, accurate quote and not inflated. Installers arrived on time, explained what they were going to do, were courteous, and thoroughly cleaned up before leaving. This is one of the best experiences I ever had with any type of home contractor.

Can't say enough about the quality of work and customer service provided by Knoechel Heating Co. Had complete heating and A/C replacement. The entire process from estimate to install was extremely professional. Bottom line is they did what they said, when they said they would do it and exceeded expectations. More than fair pricing. Highly recommend.

You WILL NOT be disappointed in hiring Knoechel heating. My oil furnace had been looked at by 2 other heating companies. This furnace is newer and has been down for almost 3 months. It had been deemed unrepairable and needed replaced by another heating company.. Knoechel was recommend as the best around with oil furnaces. I personally agree they are the BEST! Jeremey and his team were courteous and VERY reliable. They were able to have this furnace diagnosed and fixed within 2 hours. Look no further then Knoechel for your heating needs.

I had heating issues last evening when the wind chill was -20, called Knoechel, left message with the service, Jason promptly called me back to discuss the issue, told me when to expect them to get here. When Jason & Paul arrived, they were very professional, quickly diagnosed the issue & promptly fixed it. I would definitely recommend Knoechel! Cindi P.

I have called Knoechel at least 4 times since we purchased the house because they installed our systems and their name was on the furnace. Each time they were prompt to respond, the technicians were professional and friendly and the repairs were made quickly. They have been awesome to work with and the pricing fair as well.
