"I can’t say enough good things about this company. They replaced my electric furnace and did an absolutely excellent job from start to finish. Everything was done professionally, efficiently, and with great attention to detail. The system works perfectly, and the install was clean and well organized. It’s clear they take pride in their work. I’d highly recommend them to anyone needing HVAC work—top-notch service all around!"

"Got my A/C unit replaced as the old one was 15 year old. Rhett and Nova from L3 HVAC did a very good job in installing and were very professional. I feel like they gave me a fair price. It has been onlt a day but new A/C seems to be working fine."

"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."

"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."

"The service was superior from the initial contact where I requested a quote to the installation. I spoke with Samantha to arrange for someone to come out to provide me with a quote and she promptly scheduled an appointment around my schedule. Mike came out and provided me with several options for a heat pump and promptly sent me an email with the heat pump options and prices. I had contacted 4 other HVAC companies in my area that also provided me with estimates. Accu-Rite Services was the only company that followed up to see if I had any questions and to see if I was still in the process of replacing my heat pump. I called Accu-Rite Services a couple times with questions and Samantha was quick to provide an answer and was very knowledgeable. I scheduled a date for my installation and Accu-Rite Services showed up on time for the scheduled appointment. The installation was really quick, old heat pump was removed, new heat pump installed, everything completely cleaned up and new thermostat was installed. Mike gave a thorough explanation of how the heat pump and thermostat worked. Accu-Rite Services took care of registering my heat pump, scheduled county inspection and also checked for any rebates that were available for me. I absolutely love my new heat pump. I highly recommend Accu-Rite Services for all your HVAC needs. Thank you Accu-Rite Services for your superior customer service, honesty, knowledge and for making this a smooth process for me."

"Mike came out and replaced the dual capacitor-took 15 minutes total- was expecting a huge bill as air conditioning problems usually have and was surprised and pleased. Haven't had any trouble with the downstairs unit since."
