Get matched with top geothermal heating or cooling system installers in Rock Hill, SC

"I hired GSM Services to replace my A/C unit and furnace with a newer, upgraded system. A few weeks ago Kelly came to my house to give me an estimate for a new heating and air system. He was on time and very professional. He surveyed my existing system, took measurements of my house, and did some calculations to determine exactly what type and capacity system that I would need. He showed and explained to me several options as well as their prices. He wasn’t pushy as he left in order to give me time to review the different options before making my decision. I called the office the next day with my decision and to set up a date and time for installation. Today (May 22) Kyle and Craig showed up on time and were extremely professional as well. They worked from 8:30 to 5:30 completing the replacement of my entire heating/air system. The field team leader also showed up just to ensure that everything was going smoothly. They were very helpful in answering any questions that I had throughput the day and they took the time to explain to me about the new system after installation was complete (I.e. how to operate the new programmable thermostat). Overall, it was a great experience and I will definitely use them again."

"I love this company! They did a fantastic job 6 years ago when they installed a new AC unit for us. They've provided us excellent service ever since. Last week we finally decided to replace the furnace, too. They gave us the quote on Wednesday afternoon, and they were here bright and early Friday morning to start the work. I strongly believe that these are honest and fair people. I'm not at all surprised to see that they've received stellar ratings from others. The best part of all is that they fixed my daughter's above garage/east facing bedroom cooling problem. Before the work, her room was like a frying pan during summer mornings. Bradham Brothers took care of that problem like it was nothing, and they did it for a very reasonable price. This is life altering stuff!"

"The owner, Chad Adams, came out to provide me an estimate.  He fully reviewed my options, the costs, and the details of each option.  There was no pressure, just informative.  Great guy.
I decided on 7/22 to get one of the options and told Chad.  He scheduled me same day, which was a pleasant surprise. 
The team arrived about 10 and were fully completed around 3.  The installation went well, they cleaned up fully and we'd never know they were there.    The new system is great.
Overall great experience, and I will continue to use American Air for my system.

"I met the owner, who came on short notice when a company doing conversion of our water heater to natural gas did something that ‘shorted out’ our AC.  I was so impressed with their service that we signed a continuing maintenance agreement.  They come out twice a year to check out your heating and cooling system to head off any potential problems.  They haven’t tried to upsell us anything upon their inspections, they did find a ‘switch’ that was going bad and replaced it this past spring.  They didn’t say we HAD to have it replaced but that it might not make it through the summer; so we did have it replaced. It cost around $80."

"They came out within 2 or 3 hours of my phone call. They charged me exactly what they quoted me. The work was done quickly and efficiently. The price was just a little higher than some of their competitors, but they do have solid warranties on parts and labor."

"The primary problem I needed to have addressed was my laptop, which would only boot to a yellow blank screen and I was looking for a local service in Huntsville so I could drop it off if necessary.  Another major consideration was that North Alabama Technical Services was available on Sunday, which was when the service was needed.  Jim suggested some steps to clear the problem, and I was able to get the laptop to boot properly.  There were operating problems with both the laptop and my desktop computers and I was sent software to allow remote access.  Jim, at North Alabama Technical Services, was extremely professional and capable in correcting the problems remotely.  The scan of the desktop took almost 4 1/2 hours to complete, and identified some 77 infected files.  Before the scans were initiated, a number of programs were identified that had unknown sources, and were deleted.  When we began the process, I was on the phone to initiate the remote access and was impressed with the professionalism and competence as Jim talked me through the processes on both computers, and showed me what he was doing.  We disconnected during the long duration scan, but I was able to monitor the progress on my monitors and Jim called me back at the end of the scan to go over the wrap up processes.  He showed me that my 2 MB of RAM could be upgraded to 4MB and found the appropriate memory on Amazon for under $20, and loaded 3 recommended scanning programs on my computers with 30 day free trials and provided costs of the programs, if I were to purchase.
I will definitely use this service again, if required, and would recommend North Alabama Technical Services for anyone needing computer services.

"I cannot say enough good things about them. They are the only ones authorized in this area to put an aresol inside the air vents. It seals little air  leaks in your vents. It also gives protection against future mold, that kind of thing. Signature Exteriors referred me to them. They did their job exactly the way they were supposed to. They were aware. I have dogs and they were aware, don't just open the front door, the dog might get out. They were here long enough that I couldn't just lock the dogs out. You've got these big fans and blowers and all that. They took such care with my house. It's big major equipment that can only be so dainty with it. They did their best.
We still have one more piece to do. The first thing they do is they clean all of your vents. That is included in the price to putting the aresol treatment in. The aresol treatment, there's a computer to tell it what it's doing and when it's done. Getting it set up is the biggest part of the job. It takes about 2 hours to clean up all the vents and that kind of thing. The computer comes on and says, yes you have things in good shape or no you still have a gap somewhere. Well, they came last week and on the downstairs the computer kept saying you've got a gap and the man the came up to me and said, Ma'am it says that you have a 27 square inch hole somewhere in all your venting. I said, oh my gosh, let me just pay you. You spent half a day and you didn't get to do your job but that's on me not on you and he said, no, ma'am, we're going to find the hole. Well, again, all this is closed up. They start taking out the vents, using their flashlights and using their cell phones to photograph all throughout the venting of the downstairs of my house until they find a phantom vent. When the house was built 31 years ago, they closed off where a vent was supposed to go. I have been heating and cooling the gap where the downstairs ceiling and the upstairs floor, I don't know how many square feet that is, we've been heating and cooling this for 30 years. So, they said, here, let us email you the photos and let us talk to our boss. We know that we don't do this kind of thing but somebody needs to take care of this. I said that I wanted to pay them and he said there is no way we are going to charge you to get nothing done. He said, you let you know when the vent is replaced and I'll send the guys out and they'll finish the job they came to do."

"Professional and knowledgeable! His Heating and Cooling was on time and the service was done in a timely manner. I would recommend this small business over the large companies. The family oriented, friendly and top notch service cannot be compared. His Heating and Cooling will soon be a household brand!"

"My home never had a HVAC system in before. I reached out to them for a quote and it was done in a timely manner. I had four companies to come in to provide quotes and they provided the most reasonable quote for the size of my house. They came out when they said they were going to come out. Great job!"
