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!
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.

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.

Annual maintenance is recommended for all Medford homes, especially older systems working against river valley humidity.
