See What Our Customers Say

I had to give them a call when a bird flew into and messed up my cooling system. They made it out to my property that same day. The technician was very professional, courteous and sympathetic (I'm an animal lover and the bird did not survive). I would definitely recommend this company! Excellent work!

Marie Campbell


J and G Heating is the only place to go for heating and Ac needs. More then one time upon calling Jason with issues with one of our heat pumps. He provided extremely fast service and came out if not the same day it was first thing the next day. He actually cares about customer service unlike a lot of other repair shops who are only out for a buck. So if you are looking for a loyal, trustworthy, HVAC mechanic. Do not hesitate to call Jason.

I realized our air conditioning was not working this morning. I call J & G @8:30 AM. Our air was fixed by 10:30 AM. Totally impressive! The Service Tech was wonderful. Very kind and friendly. He even took the time to have a conversation with my 5 year old grandson. They installed our geothermal system 13 years ago. We've only had minor service 2 times since then. I would definitely recommend this company!

They've taken care of my parents' HVAC for years and my parents highly recommended them. I was very happy with their service. They were on time, professional, and very good-natured. Will definitely stay with them going forward.

Corey just got done doing my heater, I've had all kinds of companies do things in my home for 25 years and I've never had work done as good as he did for J and G. And myself. Very Great!
