Our air conditioner was freezing up and wouldn't cool or house. Sounds crazy right? Called several places to get availability and pricing. One Guy could come sooner so made appointment for a couple days out. They called next day because they had a cancellation and came first thing that morning. Tech was there for an hour and got us fixed up. He was courteous and knowledgeable. And pricing was better than all others I contacted. Give em a call.

This past year had a couple of issues with my heating/ac unit in the attic. Lee showed up on time and listened to what I said as to what I thought the problem may be, then Lee evaluated the issue and recommended a solution and repairs were done in time frame. This summer Lee came out and checked my attic AC and concluded that all that was needed was a new condenser, saving my HUGE amounts of money compared to the other repair persons wanted to replace the entire unit.

Then this past month needed a new heating vent in upstairs room. Lee's helper Jim did both fixes in my house and they were done in time frame and Jim cleaned up all his mess. This is by far the best Heating/AC folks out there. I highly recommend these folks. Lee is personable and friendly.

My husband was ill and couldn't do the regular evaporative cooling maintenance, so he called Oneguy. They came out right away and did a fantastic job this spring -- we were cool all summer, and also winterized our coolers in the fall. Very professional.

I had an emergency (to me), I found out my air conditioning was not running and I called Oneguy. They were able to get me in the same day, were professional and explained everything to me that was being done. I was even told how to do something myself so I wouldn't have to incur more expenses. Quick, professional and inexpensive. I love small businesses and found my HVAC company.

Lee, the owner, is the perfect example of honest, exceptional service. My husband and I prefer to work with local businesses that treat you fairly and honestly. That is OneGuy Heating. Jim, Lee's partner, did the furnace installation and he was so focused and did an amazing job. I did a TON of research on this. Both on installers and equipment.

We got the best of both worlds with OneGuy Heating. The best part? The prices were amazingly reasonable! Lee came in $2000 less than the bid we got from the vendor our home warranty company sent us. I would use Lee again, but I doubt I'll have to. Well, until our a/c goes. =
