A new HVAC system delivers more consistent temperatures from room to room and better humidity control throughout your home. Many systems also offer advanced filtration options that help reduce allergens, dust, and airborne pollutants.

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!

Is It Time to Replace Your HVAC System? Watch for These Common Signs

When your HVAC system starts to struggle, your comfort and energy bills often pay the price. Knowing the warning signs can help you plan ahead and avoid a sudden breakdown at the worst possible time.

Most HVAC systems are designed to last around 10–15 years with proper maintenance. If yours is reaching that range, a replacement may be more cost-effective than continuing to invest in repairs.

Occasional repairs are normal, but repeated service calls can quickly become expensive and frustrating. If you’re fixing your cooling or heating system every season, it may be time to consider upgrading to a more reliable solution.

An aging or inefficient system has to work harder to heat and cool your home, which can drive up your utility costs. A new high-efficiency system installed by GEM can help lower monthly energy expenses.

Hot and cold spots, weak airflow, or a system that constantly runs are signs it’s no longer performing at its best. Replacing your equipment can restore consistent comfort and give you better control over your indoor environment.


Start Your HVAC Replacement with a Team You Can Trust

When your HVAC system can’t keep up, you deserve a solution that’s efficient, dependable, and built to last.

Schedule your HVAC replacement consultation with GEM today to take the first step toward improved comfort and lower energy costs. Our team makes your HVAC replacement simple and stress-free from start to finish.
