"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."

"It went very well. I had spoken to several contractors, including one that chose to bash other contractors. Acosta was always very professional and the price was equivalent or better than the others. The sales rep let me change my mind a few times and patiently worked with me. I also found out that they have a contractual relationship with Costco. So as a Costco member, I got good discounts and the assurance that they stood behind the work of Acosta. The day of the install they had 2 crews present. There was an initial mix up about equipment, but they were prepared to give me an even better deal if they could not sort out the problem. Turned out to be a non-issue after all. It was a long hot day (August), but they got the work done in the one day. Finally, they handled my Duke and Piedmont rebates directly and set up my inspection with a set day and small time window. I couldn't be happier."

"Always fearing the cost of replacing the furnace or air conditioning unit, Brothers replaced both when my furnace went out. Both units I had for 27 years. So it was time. I was suprised the cost was relatively cheap considering both units were replaced, new thermostat (that you can also hook up to your wi-fi) was installed and a carbon monoxide detector."

"The owner Mike made the call. Very professional and knowledgable. This house is new to us and we were quite sure the units had never had any maintenance done on air conditioners. The house was built in 2001. When the upstairs unit stopped cooling we called Accu-Rite. Got the name from our neighbor who had used them and was very pleased. We would use them again especially when we replace units. Would highly recommend. The company doesn't advertise much as the owner wants to build his reputation on quality work for his customers and word of mouth business. He took the time to answer all our questions and never ever tried to sell us more than was necessary or appropriate.

"Great experience. Gary, the estimator showed up on time, evaluated the existing upstairs AC, and gave me two options to replace the evaporator coil and outside condenser with firm prices. Included in the estimates was also addition work I requested. All of the work was done the following Monday. The new unit is 2.0 SEER2 better than the old unit. Bradham Brothers included a new programmable thermostat with WiFi access. They also provided two new CO2 detectors. The county inspector was pleased with their work. All total, Bradham Brothers exceeded my expectations."
