Super fast response time (called at 4:00 on Monday and Mike & Chris were at the house at 11:15 on Tuesday). Mike and Chris were excellent, diagnosed the source of the odor (bad wax ring) and completed the job by 12:15.
Everything from the initial phone call to the quick response from our techs and the repair of our system was an A+! Would recommend to everyone.
GEM was one of only services that got back to me and scheduled me on the same day! Colin was quick, professional, and someone I felt safe having in my home. You get what you pay for!

Khorey J. and his colleague did an excellent job inspecting our heating and cooling mini-split system. They took the time to explain the issues in detail and gave us peace of mind and at ease by ensuring that everything was working properly. They also explained and demonstrated when the condenser fan should turn on at various temperatures and settings. Both men were knowledgeable, professional, polite, and respectful. We have been customers of Gem Heating and Plumbing for many years, and, as always, they were there when we needed their services. Thank you, Gem Plumbing!

Have used GEM several times. After some rough experiences with some other HVAC companies, I can say GEM has been consistently outstanding. Highly recommended.
We had an emergency service performed on Saturday, the technician Chris was professional and talked me through everything he was doing. I’d rate his overall work on a scale of 1-10 as over 10 because he was that awesome. What gets me is the pricing of the service. As I mentioned it was an emergency, and as the customer I want an itemized breakdown of parts and labor. I just called GEM and they mentioned they do not provide that. I will continue to call until I get the satisfaction I want on full disclosure of MY billing statement the was paid for in FULL by MYSELF. I know GEM reads these reviews and I want my fully itemized bill for services rendered.
Very satisfied with the service

FAQ

Do you provide same-day AC repair throughout Somerville?

Yes. GEM offers same-day air conditioning repair across all Somerville neighborhoods, from Davis Square to Assembly Row to Winter Hill. Call before noon and we can usually get there the same day.

Can you service ductless mini-splits in Somerville?

Absolutely. Mini-splits are common in Somerville’s condos and multi-family buildings. Our technicians service all major brands and can repair or advise on replacement when needed.

What energy rebates are available to Somerville residents?

As a Mass Save® partner, GEM helps Somerville residents access rebates on qualifying high-efficiency equipment. Rebates change seasonally, so we check current offers and handle the paperwork for you.

Why does my Somerville home stay humid even with AC running?

Somerville’s dense housing and older construction often mean undersized equipment or systems that can’t keep up with humidity. You may need a capacity assessment, condensate drain cleaning, or whole-home dehumidification. Our technicians diagnose the actual cause.

How often should Somerville residents schedule AC maintenance?

Annual maintenance is recommended, ideally in spring before you need cooling. Older systems and units in triple-deckers that run hard all summer benefit especially from yearly tune-ups that catch refrigerant leaks, electrical wear, and airflow problems early.
