    John was amazing! I called him late Friday evening and he was here by 9:55 Monday morning. Not only is he professional, but he's very knowledgeable and friendly. You can tell he truly cares about his clients. I would 100% recommend him for the job. Plus his pricing was incredibly fair. He even came back to ensure there weren't any gas leaks. Calling him thorough would be an understatement. I could go on and on about how awesome he was!

    I trust no one else other than John for our HVAC needs. We have needed his help three times over 10+ years of living in our home. He has always delivered in customer service, knowledge, and quality of work. He is communicative and is very transparent in the work that needs to be done and associated costs. I could not recommend him more to anyone needing the services he offers.

    This is the third time we've called Jon at Core Heating. The last time was five years ago in a different house where he installed a new furnace for us which we were super happy with. Now we're in a new house and he just came out and found the simple problem that was caused by some crazy old electrical confusion here. We have our heat back now that the weather is turning colder! Thank you, John. You are always warm, personable, and I appreciate your depth of experience and the advice you give for a new homeowner. You are the top of my list for who to call.
