What our customers say

Vent cleaning for clothes dryer. Was on time and very quick.

John Major

I have used GSHA for two complete home air and heating installations, my first was in Crystal Lake I never had any issues. Peter sent in a team that removed the old equipment and replaced all connected components that were to be attached to the new components, assuring smooth future operations. I felt confident that the job was done properly. I never had any issues. Service was never an issue either, they did annual service checks and through the fantastic warranty is all hands down and beat any other company we researched. Upon selling the home in Crystal Lake I move 100 mile south. My only concern was that GSHA didn’t service the area. Atter 6 month of moving into the new home and being discouraged with other companies I called Maria from GSHA and she said they do service the Bourbonnais area. Peter the owner drove all the way down here and in 2 days the heart and soul of my home was beating again with the quality and best warranty a company can offer. I had made other inquiries with the local Havc companies during the first 4 months of living down here and discovered return service calls were late in coming and the slap shot work done on some of my plumbing from Bennett Heating and Air was a disaster and disappointing. No warranties for the work done just give them the money. You don’t get that with GSHA, you call and they come and fix it, no worries. They are very professional, affordable and they work with you. I have peace of mind and know the work was done right and they will always be there. Hats off to Raymondo and his brother and also Jacob and D.J.. A huge thank you to Peter and Maria. My moto is….GSHA is, The best in the Midwest.
