General Service Mechanical, LLC Air Conditioning & Heating

I had a really old oil boiler that was leaking water and had to be replaced. I had a spare gas boiler and Gary did a awesome job swapping out the boilers. He was one time, clean and a great personality with good prices. I highly recommend Gary for all your HVAC needs!! TY

Gary was great. He came out the same day that my heater broke and he made sure that it was working before he left our home! It went down the day after a major snow storm so we were very concerned if anyone would make it here but, he did! What an awesome job and human being. Thank you so much Gary for your services and being the real great person that you are!! Not only this but our heater is old. This man figured a way to get it working for us when he didn’t have to. If you need someone that actually cares for his customers and does a great job then this is the guy!!!

Very good experience with Gary. Friendly, very helpful, gave a better price than a big company. He did same day diagnosis and fixing of the problem.

Gary is a great guy and very knowledgeable at what he does. Excellent customer service and a grade A+ on his work.

Excellent service, Gary was on time and changed everything, left everything clean and working properly the same day. I am so happy having a warm house 🏠 100% recommended!
