Gem is always reliable. Technician was very knowledgeable, really understood steam system, burner components and was a good communicator, able to answer all my questions and give guidance on aspects of water levels and valve settings.

Tony from GEM was amazing! He came to our home and diagnosed the issue, picked up the part, and had hot water to our home within a short period of time! He’s professorial and intelligent! Highly recommend!

Everything is good 100×100 perfect

Omar and the guys were very professional. They did a great job installing the mini-split. They were very informative. They showed me how to run the cold air and the heat. Omar put down cloths on my floor to protect them, I was thankful for that. I will definitely refer Gem if any of my friends are interested in a mini-split or mini-split.

GEM's arrived on time, checked the HVAC and made recommendations. The gentlemen were neat, clean and polite.

Brody was amazing and helped get the system up and running.

They were on time, very quick, very polite and provided a link to something that I can purchase on my own to save money.

We had a oil furnace and oil tank installed. They took great care of our home and went above and beyond my expectations. They made a very stressful situation something easy to deal with from the communication to sales to install. I thought at first the price was a little high but for the level of professionalism I received it was worth it.

Aiden was great!! Diagnosed problem, went to get part;All in time wise less than 3 hours and that included a service on our generator. He was knowledgeable, efficient and polite.

Great service! Professional, detailed, good communication with all services involved. I would highly recommend them for plumbing and heating needs!

The service was good and the team was very professional, thank you.

Chris was on time, friendly and extremely competent. He replaced the thermocouple and answered my many questions about the heating system while he worked. 5 stars.

I had very stubborn severely clog drain. Edward and Caleb arrived to clear out a clog in my kitchen drain. They were prompt, very polite and professional. They made me feel at ease. They snaked the pipe, cleared the clog and ran an over flow of water to be sure the pipes were cleared. I felt very safe home having these gentlemen here, and would recommend them to friends and family. If I need services from Gem in the future, I would be pleased to have them again

Very pleased with the installation of the two new boilers, a 100,000 btu steam boiler and a forced hot water heater since needing the heating systems separated for my tenants. The crew and management worked together well and strove for customer satisfaction. The crew worked with me addressing issues and worked to resolve all issues. Tim, Tony and Rob, the field supervisors are on the ball and work to resolve all issues both with the boilers and electrical. Roselio, Jacob and Byron are amazing employees and hard workers. Had Eric and his assistant come back out to the property to do Some service on the brand new boiler since there was a lot of residue in the pipes. They got the situation quickly resolved, and everything is running to standard and well. The crew was very professional and honest.

Service tech , very friendly , knowledgeable and outgoing. Very happy with the service

Nicole was absolutely great and on top of diagnosing and quickly resolving a problem, a leaky radiator valve, she went beyond and made sure the whole system was functioning properly and was all buttoned up for the winter. Many thanks Nicole!

They were smart, communicated well, professional. Explained things to me. They felt trustworthy.

Great job by Timothy and Aidan

Very professional

Great professional and friendly service. Easy to set an appointment and they came early in the appointment window, showed me before and after pics/videos and did a great job!

Super fast and professional service!

Dori of GEM did a great job flushing my boiler and replacing the boiler control board. He was professional and focused. He went beyond the call of duty and reset my thermostat to a higher temperature in anticipation of the cold weather expected tomorrow. I would definitely request that he work on any HVAC-related repairs that may come up in the future. He also brought a lot of positive energy to the house.

Great job, and very knowledgeable!

I would recommend GEM to everyone. Quick Serve and do professional!!

Michael did and excellent job and was thoughtful enough to carefully cut the drywall to make the repair easier. Huge bonus. Straight shooter who do good work. Definitely recommend.
