Customer Reviews

Mary D.

Best service technicians and customer support, often able to get same day service. Today our air conditioning went out, called Gregg Heating, Kyle came right out found our problem replaced wire and we are cooling 😎.

Jeff T.

Kyle and his team replaced my aging furnace and AC. Kept in contact for scheduling and any updates. Did a great job on the install, taking extra care putting down runners and plastic as not to damage or dirty my floors as they came in an out. They were in and out in a half day. Walked me though the unit, answered any questions I had. ...

Diane C.

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 ...


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.

Lloyd B.

Gregg Heating and A/C is awesome! Their service is excellent, and they give really straight answers to questions about equipment, repairs, service, everything. They are people you don’t mind having in your home, and they have always done everything they said they would. Zero problems with scheduling too. In the past 15 years I have purchased two furnaces and one a/c unit, and have had them ...

Jane M.

Gregg Heating and Air Conditioning did a great job of installing our new air conditioner. The owner answered all questions we had prior to purchase and came out with a sample base pad to make sure that if we ordered the air conditioner it would fit properly. Their work was very professional. They also provided little extras like putting dirt I supplied around the base of ...

Donovan C.

I have had greggs come and do work for me numerous times many of the times with a demand of urgency they have always taken care of me in some way shape or form. Will always be my first reference when anyone needs work done.

Alex G.

I have been a Gregg Heating Customer since 1995. They put in my first gas furnace in 1995 along with my first central AC. I had Gregg Heating install a new furnace in 2014 and they just replaced my 25-year-old AC today. The technicians did a wonderful job installing all of my equipment. Throughout my years with Gregg Heating I have been impressed with their excellent ...

Mike T.

I have used the products and services of Gregg Heating and AC for 26 years. They have never done me wrong and the service has been excellent. They are one of just a few businesses that I have the confidence in to recommend to my 88-year-old mom. They did great at her house too. Thank heavens!

Pamela G.

I had my A/C unit and furnace replaced at the same time. Kyle, the owner, came out promptly to give me an estimate and he was there the following day to install the units. He was on time and very professional. When he finished, he went through the new units with me and showed me how to program the thermostat. I would definitely recommend his company ...

Wayne G.

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. ...

David P

Kyle and his team replaced my AC system quickly and ahead of schedule. Thankful to have such a reliable company in the area. You won’t be sorry for using Gregg Heating & Air Conditioning for all your HVAC needs.

Mike B.

Fantastic service; came out and properly diagnosed my problem and they moved things around to install a new furnace first thing on Monday morning. I even priced checked them and they were much lower and provided great quality service…they will be my heating and AC company for life.

Bryce C.

Look no further if you are seeking professional, honest, and high quality HVAC service.

Anand P.

Kyle and his team are the best. Our furnace crashed over the weekend, and Kyle was very gracious about helping us that very day. Knowing we have small children, he rearranged his schedule so that we would have working heating as quickly as possible. He diagnosed other problems that were causing known inefficiencies in our heating and fixed those as well. Also, because the original problem ...

Rebecca L.

Excellent service. They were very responsive when our air conditioning was not functionally properly. Fast and reliable turn around time for installation of new furnace and zoning system. Thanks!

Lynn T.

The hottest day of the year and the AC froze up. It was old and replacement was what we were looking at. I thought it would be about a week before we could have it installed. Greggs had a new unit installed the same day! Awesome service and super friendly detailed guys. They are definitely gonna be our go to from now on.

Gail H.

I hired Gregg’s heating and A/C to put in a whole new central air unit, including condenser. Our home has a boiler system, and hot water heat, so the unit had to go in the attic. They quoted me a very good price for a very good unit, and on top of that my unit had a very very good warranty/ above and beyond other warranties. ...

Tyler S.

My family and I just returned from vacation and our A/C wasn’t working on the hottest day of the year. I called Gregg Heating & Air Conditioning and Kyle was at my house within an hour. Kyle found multiple problems with my A/C unit and had it up and running within an hour. You have a new customer for life!

Nikolai M.

My furnace and AC unit were pretty old. The furnace finally went last week. My dad had a furnace installed by them previously and had a great experience. He sent me their contact and after giving them a call, I can say the same. Very pleased with the entire experience. Staff were all friendly and did a great job. The next day everything was finished and ...
