Get matched with top heat pump installers and replacers in Rock Hill, SC

"Horne replaced my 2-ton HVAC unit. I was impressed by the extra detail and quality in the estimate, such as putting pressure-treated timbers under the composite pad on the outside, as well as adding a surge protector and noticing that I needed to change my outside flue to comply with newer building codes. Sales did not do a good job communicating the added purchase of retrofitting my existing outdoor unit with timbers and leveling the unit. The installation crew had no knowledge of this or the addition of antivibration pads, which are in agreement. However, they made it right and completed the work successfully. The installers, Colin and Mason, are the shining stars! They worked diligently, without complaint, in the cold rain and muddy landscape, adding the additional work that they were not expecting. They were thorough and completed the job to our satisfaction."

"<p>GSM has been in business for a very long time.  I know why.  GSM was professional from the original contact, to the quote, to the install, the testing, and the follow up.  The advisor answered my questions, and was available later for follow up questions.  They gave me a range of quotes which I really appreciated and helped me make a fair comparison to other quotes I received.  This company guarantees your satisfaction and comfort, and they give that to you in writing.  They were willing to work with me on scheduling the installation, and kindly provided a portable unit to keep me cool overnight.  The weather was in the high 90s and this was a two day job.  The technicians who actually did the work were courteous and respectful of my home.  I felt completely comfortable with them coming in and out as needed.</p> <p>Once the installation was done, they gave me good clear instructions on using the system; I feel comfortable with the programmable thermostat.  They cleaned up after themselves well too.  They have provided detailed information on how I can reach them with any questions or concerns.  These guys understand customer service.  I anticipate a long business relationship with them.</p> <br />"

"We started beginning of August with the Central AC going out ( but only in downstairs of home). Technician came out and diagnosed issue, we needed major component MOTOR. It had to be ordered. He offered us a window exhaust/ portable AC for some very small relief from August heat to use our kitchen area. The motor was supposed to take a month to come in. Several months passed and another technician called to come put the motor in but it now was noticed we also needed the fan that attaches to the motor, another ordered part. Very Long Story short, in DECEMBER, the actual repair was done but guess what, it would not heat like it should it made wobbly noises and I knew it wasn’t right, the heat never came up to temperature as it was not blowing with any pressure. So I called them again. They finally were giving us there best technician Robert, what a life saver! When he finally diagnosed the computer part of system as being issue as well. This was after we replace all the ductwork in our crawl space. We spent a TON of money on this repair but a replacement would have been more and we are so grateful for Robert being hardworking, respectful, knowledgeable, patient, to stick with this repair that until he showed up at our door was an absolute nightmare. Robert you deserve a HUGE raise."

"Customer service is the worst ever. Technicians are great had new Heat Pump installed 3 weeks later AC went out. Two days later finally got tech out found problems with leak in new coil in inside unit. Could not fix because was a factory weld Supposed to replace coil have not heard anything weeks later. Call CS told manager would call me. Still waiting"

"Service Tech msg when he was on his way. Arrived on time and was very professional. However, the estimate for the replacement unit was 3 times higher than what a unit should cost to replace. So needless to say, I was disappointed in their quote."

"The service was amazing! Very thorough and walked my husband and I through the entire process. I will definitely be recommending this company to anyone in need of HVAC services! "
