Jerome Went beyond to make sure that my New Furnace and Air Conditioner was installed and working properly. When I had Questions he Answered or returned my call even on the Weekend.

Thumbtack customerJul 2026

GMH responded quickly and was able to install my wall air conditioner same day. The technician was very knowledgeable and a pleasure to talk to. I would highly recommend GMH

Thumbtack customerJun 2026

Honesty, integrity, and efficiency—qualities very few in this business possess; I am very satisfied.

Thumbtack customerJun 2026

The guy showed up to check on my AC and said that my AC don't need freon recharge and that I need to change my filter. Basically he didn't do any service and he charged me $160. On the app his service charge is $75. I asked him why he is charging me double because he didn't perform any service - he said that someone needs to cover his gasoline. Total rip off and ridiculous man to work with. I would never recommend him to anyone. Stay away!

Gerome got right back to me after I requested a quote. He sent out a employee of his within 30 mins. Jim was so helpful, he explained everything he did to my furnace and took pictures before and after! Great work ethic. I would use them again and recommend them to anyone. the price was very good also.

Justine Michael b.May 2025

Gerome provided me with a quote that was really competitive and reasonable. Him and his partner came in right away the next day after negotiating to an agreement. Great install and was very thorough with the run down of the ac and furnace.

One of the best services I have ever received. Gerome was Punctual, responsive and provided great quality work. He was a complete life saver and got the work done quickly. I would recommend him to everyone and will definitely use him again for any work needed!

Sandra M.Jan 2025

Gerome and his assistant. Very straightforward and knowledgeable. We will definitely use them in future and recommend them to our neighbors and friends.

Sam D.Dec 2024

I hired Gerome to fix my furnace and humidifier and I could not be happier with the work he performed. On the first visit he fixed the humidifier within an hour and special ordered parts for the furnace. He returned 2 days later and fixed the furnace promptly as well. Could not recommend enough!

Arthur R.Nov 2024

ABSOLUTELY one of the nicest, trustworthy, clean, professional on time like a Marine individuals I have ever met. His price was DRAMATICALLY lower than EVERYONE on Thumbtack and every "big name company". He installed my furnace in a beyond exceptional time frame and left zero debris on my floors. I'm going to be 100 and tell you all I haven't run my heater days consecutively but I'm willing to bet my paycheck if there's ANYTHING wrong he'll do whatever it takes to rectify. BRAVO Gerome
