HVAC reviews in Durham, North Carolina

Frank was great to work with. He was professional and thorough. He explained everything clearly and was concise with our optionsmoving forward

Great job - replaced our geothermal system, good work, nice guys. On time, got it done. No complaints at all.

We were without heat days before Christmas; our home insurance service took 2 days to diagnose the problem and wasn't going to fix it until after the holiday~ Greg at Green Horizon did the job in 1 hour saving us from freezing and unnecessary big bills! Thank you for your speed, professionalism, ethics, and personable service.

Frank did a great job diagnosing and correcting our ac problem and took the time to show me how to correct it myself if it happens again. Excellent service!

Great experience with both the initial installation and recent repair of a gas tankless water heater. Customer service and technician experience were both excellent. Another plumber told us we would have to replace the whole unit but then Green Horizons correctly diagnosed that it was a simple part that needed replacing. These folks won’t scam you!

Great experience with the Green Horizons techs who came out to inspect an HVAC system in a home my clients are under contract to purchase. They were knowledgeable and courteous, and I’d gladly use them again!

The tech came to us in the rain on time.
He was informative in explaining the problem and fix quickly and heat was instantly working!!

Bobby was here slightly ahead of time, which was great! He was friendly, direct, and gave me recommendations on each question I asked. I like that he owns this company and was honest about why he chose to get connected to a franchise.

Tyler arrived on time, was nice, and had clear communication about our HVAC system. This was a regular maintenance call, and we were very satisfied with his work!

Green Horizon's two man crew worked very hard for 4 hours at our home on Th, 8-7-25. We are very happy with the results and are looking forward to lower heating and cooling bills.

Great experience and communication from Shedrick with Green Horizon - trust his expertise and advice.

Two nice fellows, Zahi and his assistant, sealed our attic and installed insulation to the standard of current recommendations. One of the men accidently broke a ceiling, but the company contracted ceiling specialists to fix it, which they did, as good as new. So no complaint.

Updated: These guys were timely in commucating, were priced reasonably, and showned up when they said. I initially gave these guys a 5 star review because Jason seemed professional. I took a look in my unit a week later and found that my evaporater coils and fan had mold buildup that was never mentioned to me. Cleaning these is not part of the regular service offered because chemical need to be used. I had asked for some air quallity information and was given a quote to replace the ducts in my house. They are not insulated in my crawspace. This is a good suggestion, but it seems like a better place to start is to clean the mold out of the unit itself. Anyway, probably won't be using these guys again.

Frank was respectful, thorough, and kind. He added some extra sealant that was needed and made sure that everything is ready for inspection. He wore booties over his shoes, as not to track mud in the house. Frank also offered to replace the grill on the return since ours was from 1983 and caused whistling noises. Happy with our interaction with Frank.

This was our first time with Tyler after only having Anthony for years so we were very concerned as to what type of technician he was going to be, but upon meeting him he was very respectful and appeared to be very knowledgeable and actually pretty much like our favorite guy Anthony and did the maintenance in around 30 minutes he then proceeded to tell us that everything looked good but that there was a part outside that was worn and would eventually go bad and showed us a picture and advised us what would happen and what to do when it happened and to call them they would order the part. I then asked him if they could go ahead and order the part so that we would not have to wait days for it to come in and he told me he could but honestly I am not very confident that this will happen and that is a concern to me but other than that he took the time to answer all the questions we had. I definitely think this company is a good solid company and I believe its because of the owner Bobby Ferrel so until something happens that makes me think otherwise they definitely will be my number one go to and who I will continue recommending to my friends and community to.

Anthony did a great job correcting a minor problem he discovered during previous visit to install condensate pump. He didn't have time during the earlier visit but he returned today to fix the other problem. He is very thorough and conscientious!

Called twelve times yesterday between 12:30 and 7:00 p.m. and kept getting a message saying "we are out of the office or busy with another client, leave a message." I didn't leave a message because I wanted to talk to someone since I don't keep my phone near me and often miss calls. I tried to book an appointment online and got no response from that.

Today I called again and got the same message. The second time I called, I decided to leave a message asking if there was a different number I could call to get through (I had been calling two different numbers and got the same message from both).

When I got through their "we're not here" message, it connected me not to voicemail, but to a person. When I tried to explain to the person what was happening, he copped an attitude and didn't seem to understand the issue, and as much as called me a liar. "I was here all day." Maybe you were, but that doesn't stop your outgoing message from making people think no one is available to talk to.

I see on the reviews that someone else was having the same problem, so maybe fix your phone system if you don't want to keep losing customers, as you have this one.

This is my 2nd time working with Green Horizon. They have been great to work with. From Lori coordinating calls and sending someone out timely, to the knowledgeable technician to complete the repair. Shout out to Ricky for keeping me updated during the repair and his dedication to ensure the job was done right!

Tyler arrived on time, was courteous, and had good knowledge of my system, a Daikin mini-split. He explained everything clearly and made sound recommendations for extending the life of my HVAC system.

Such a good experience! Our unit went out overnight GH had a tech out real fast. Tyler was amazing and fixed the issue quick and explained everything in detail to us. Will be using GH again!

Incredibly impressed with Bobby and Frank's thorough approach and attention to detail. We had a variety of concerning issues and of course wanted to address completely for the health of our family, and Frank left no stone unturned in making sure every part of our house and system was assessed. Recommend them highly!
