Covenant Heating

John, the owner of Covenant Heating, was outstanding from start to finish. He was incredibly thorough and detail-oriented, taking the time to properly diagnose everything instead of rushing to conclusions. He walked through the entire system step by step—inspecting the exhaust for blockages, checking the heat exchanger, and running combustion tests—all while documenting everything with photos so I could clearly understand what was going on. What really stood out was his professionalism and honesty. He identified a leak at the outdoor oil tank, shut the fuel supply off immediately, and made sure everything was safe before leaving. No guesswork, no shortcuts. If you’re looking for someone who actually knows what they’re doing and takes pride in doing it right, John is your guy. Highly recommend.

Prompt, thorough and very knowledgeable. We highly recommend them.

I found out I had to replace the entire boiler and called John on a weekend. He called right back. By Tuesday everything was installed, restored, and working better than before. I’m so grateful for the service time, responsiveness, efficient work, and the amount of time answering questions. John and Ben were amazing. Covenant Heating has a new life-long customer!

John is reliable, quick to return a call and charges a fair price. He is our “furnace man” since we bought our house 2ya. He explains what he is doing and why and is great with answering questions. He is decent and polite. We recommend him to EVERYONE and always here good things in return.
