I’m very pleased with the work done by Cristian & his helper. Communication was very much appreciated – every question was answered and explained throughout the entire project. It’s rare to find someone who takes pride in their work these days. I would highly recommend GEM to anyone looking for a skilled contractor.
Had a leaking T&P relief valve on my water heater. Called GEM, they came out just a few hours later, replaced the valve with a new one, and they could not have been nicer or more professional. Very satisfied and grateful for their speed and knowledge. Would absolutely call on them again. I did not pay anything because I am under warranty.

We needed a new furnace. They sent someone out the next day to provide an Estimate. The price seemed reasonable and the discounts made it even better so I booked them to complete the job. I received a call later the same day and had the furnace installed the following day by Ethan and Kevin. The following Monday, my furnace would not fire. After evaluating the situation it was found that we needed to relocate our exhaust pipe. Ethan and Kevin were sent to do the job. The original installation was done in less than a day and assessing and relocating the exhaust pipe was done in a few hours. I am happy with the service.

Both David C was excellent! Hecame on time, walked me through what needed to be done, and when completed showed me the final product. He was very professional, pleasant and respectful of our home. I strongly recommend him for any repairs needed.
Their $99 promotion — main drain cleaning + camera inspection — is a great deal. The guys who did the work were very systematic, surveying the drain pipe both before and after cleaning it out, and explaining what they found very clearly. They followed up with a proposal for fixing the pipe. I will of course bid out the repair, and I have no information about how efficient and economical they are for doing this work.

Living on the Cape finding a reliable service company can be difficult. GEM is now my go to for HVAC and plumbing service.
> Five stars for Davontay V. He came out to our Foxborough building for a no-heat call, found a loose heat-call wire in minutes that the previous tech had walked right past, reconnected it, and there was no charge for the visit. Professional, fast, and honest. He's our requested tech from now on. Additionally, Davontay also put the lock cover back on, locked up every door, shut off the lights, and took care of a few small cleanup items that weren't part of his job — all without being asked. Great job!
