UPDATE: After months of trouble with our previous oil company, GEM initially felt like a huge step…read moreup. Harrison came out expecting to be working on a gas system despite us telling the dispatcher we have an oil system. He and made a real effort to help us. But we were expecting him to give a quote and instead handled most of the major issues the same day. Or so we thought... His initial repair ultimately took three more separate visits to get right. The issues we ran into after the first visit could have been avoided if the initial work had been completed correctly, but I appreciate that GEM honored their warranty and kept coming back without charging us extra. The final technician, Steven, was the one who fully resolved everything. He corrected the earlier mistakes, updated the piping, bled the system properly, and fixed problems that had been building for years, even parts that weren't effected by the initial repair were replaced to ensure efficiency and to avoid further damage to the system. Our heat now works better than it ever has, and Steven genuinely deserves five stars. Because of the multiple visits and avoidable setbacks, I can't give the company a full five stars, but I'm grateful for the Steven seeing it through!

EXTORTION! AVOID AT ALL COSTS! I had a refrigerant leak in…read moremy whole house heat pump system. Gem came and refilled the coolant and charged over $800. They also added UV dye to find the leak, and said they should come back in a few months to track down the leak. All the coolant they added was gone (and the heat was not working again) in less than two days. Gem came out again and identified the leak in the curve of a copper pipe. They quoted almost $10,000 (!!!) to replace the line and refill the coolant. Another company came and did it for $1,800. Half of the price they quoted (almost $5k) was for the cost of the coolant, which shows that they put a MASSIVE mark-up on it. This made me realized that they had probably overcharged us for that $800 coolant refill -- which did not fix the problem anyway -- so I wanted to file a complaint and get my money back. But I couldn't because (get this!) THEY DON'T HAVE AN EMAIL ADDRESS. You can only call them. What kind of reputable company doesn't have an email address? I think that tells you everything you need to know about them.

Even better, everyone involved from Kyle to those in the office to the crew was readily available, friendly, and easy to talk to. Long story short: Martel is great and I strongly recommend them.

Adam looked at our air conditioner and immediately identified the problem, explained it and took care of everything. He wore foot protection and cleaned up everything. The price was very reasonable and Adam recommended cleaning once a year and changing the filters twice a year. I highly recommend this company.
