GSHA Services installed a heater and AC unit in my home. It went great and I’m very happy with the result. It was a great price and great service. The installers were very professional and I’m very happy with their service. I would recommend them to my family and friends. Thank you

GSHA did a great job for me. They did the work for the exact amount quoted and even threw in a free thermostat, when they saw how old my current one was. I was able to get a quote easily, through a computer chat. I didn’t need a salesman to come out to my home. The installers come out the next day and were polite, friendly and did the job quickly and professionally.

Great job of scheduling, coming on time, doing a good job. The team was efficient, friendly and explained everything really well. The system is working really well and a big improvement from my old HVAC installation.


My AC and Furnace stopped working due to an electric shock (Probably weather related). I called Peter and their customer service and quality of work was great. I have seen many GSHA reviews online for AC and Furnace install, but I want to point out that they are great with electric work also. They fixed the short and replaced the electric panel and also ran a ground so this electric issue that I had will not happen again. Great Service.
