Replaced and installed our new furnace including duct cleaning before installations. The crew was fantastic and did an excellent job. Shout out to Peter and his guy for doing the duct cleaning quick and fast. It only took an hour for 2 returns and 4 supply vents. Special thanks to Raymundo and his partner for patiently removing the OLD BOY furnace and they both diligently work together fabricating the ductworks including the layout of intake and exhaust piping for the furnace. Job well done gentlemen and Salute! I highly recommend this company and special thanks also to Mr. Peter Nosal for giving us the best quote and affordable price and warranty compare to other suppliers and to Ms. Maria Loboda who patiently did her job communicating with me by giving us the options in our convenience the schedule before this installation. We will be doing business again with this company in the future! ⭐️⭐️⭐️⭐️⭐️

Was a pleasure working with you Great and professional service , Thank you

Responsive, efficient, and effective service to repair lighting that had gone out and another company (I had used for 30 years) was too busy to fully address. Dawid and Oscar identified and addressed several issues with wiring in my home/garage. Very happy with the service.

Dawid and his crew installed a whole house backup generator system and did an amazing job. Work was professionally done and the entire crew was extremely friendly and knowledgeable. We couldn’t be happier. Just had the inspection done. Passed with flying colors. Thanks again for all the great work

WOW!!! Great Service! Great Product! Great Price! Great professional Service!!!

Great service very friendly and reliable

I own a 3 flat and had to replace, urgently, three hot water heaters. GSHA came in at 9 AM, I was very happy with the quote and GSHA proceeded with the installation of all three hot water heaters and were done by 6 PM. The quality of service was excellent, and all units are working perfectly. Thank you GSHA.
