After a few quotes for new AC install, selected Gregg. Appreciated that it is a smaller company, Kyle the owner comes to do the quoting. He is knowledgeable, reasonably priced, and helped troubleshoot a few other minor issues unrelated to our AC install. Also always on time & responsive. Service: Install AC

I wanted to replace my 20 year old Rheem furnace before winter, and went with Gregg for two reasons: One, they are a Rheem "ProPartner" company, so they have the experience with that brand that I was expecting. As for reason number two, the previous reviews listed here gave Gregg Heating the edge. As for the work, swapping out the old for the new was a bit easier because in my case the Rheem fittings lined up well with the previous model.
The installers also helped improve our return air, increasing the flow via larger duct work where the return connections meet up with the furnace. The installers kept the place clean, they were on time, they answered my questions, and were out the door in less than a day. There was no hard sell, no upsell, just good service. The installer tested everything before leaving, and I'm looking forward to years of heat without worry.

We were extremely pleased with our recent experience using Gregg's Heating And Air-Conditioning. Our air went out on a VERY hot summer's day and as our senior dog just had major surgery we were very concerned for her wellbeing in the heat. My husband called and due to a cancellation they were able to come out within a 1/2 hour. They found the problem and were able to put in a new unit 2 days later!
They were professional, hardworking, honest and even put down a runner to protect the floor! We would highly recommend Gregg's Heating and Air Conditioning to anyone in need of service. Thanks for your great service.we slept great last night in our COOL house!

We just had Gregg Heating replace our 25 year old Rheem furnace and AC. After all those years of trouble-free service, we were only interested in Rheem products. Kyle was the third company we had come in to quote our needs. His presentation was the reason we had his company do the installation. He smoothly presented all of the product information, yet never tried to "up sell" our purchase. The day of our installation, he arrived on time, laid down carpet protection, repaired some ductwork, made the installation, and cleaned up. We are very pleased with Gregg Heating, and we will do it again in 25 years.

We replaced our baseboard electric heat with a forced air furnace. The technicians we're very helpful throughout the entire process keeping us well informed. They showed up promptly each day and gave us updates in the days progress, even walked me through the new thermostat. The price was right on board with the estimate and no surprise additional costs even our home provided some unique challenges. They kept on track with budget and schedule and gave us tips on how to maximize our new units efficiency. I would definitely recommend their services.
