While most of their technicians do a good job, I have to give GEM a mixed rating:…read more 1. Their prices can be outrageous; e.g., $500 labor charge for 15 minutes installing a $125 replacement thermostat, when other electricians charge $100-150. They quoted me $6,000 for a job that I had performed by someone else for $3,600. 2. They have a terrible front office. They never bother to call to alert you that the tech will be hours late, they never leave or e-mail an itemized invoice for work performed, and they frequently give incorrect information to the tech about what service needs to be performed, wasting my time and the tech's. I suggest writing down the names of the techs who are good and demand that only one of them come to service your house.

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!
