GEM plumbing recently installed a ductless minisplit system in my home. The installers did an excellent job. They were extremely knowledgeable, courteous, and patient. They communicated with me every step of the way and took the time to answer all of my questions. The system is working beautifully. If you are looking for a contractor to install a ductless minisplit system, I highly recommend GEM plumbing.
I do wish it hadn’t been so expensive, but I will say I really did feel like my technician understood what he was doing. He was knowledgeable and professional. He explained things well and I’d be happy to work with him again.
William (Bill) and Antony arrived promptly and serviced my boiler system – everything is up and running smoothly (and the hot water is back).!

Both service calls to my house were with Nick, and I can't say enough good things about him. He's professional, courteous, communicative, and thorough. My only hiccup with Gem has been conflicting information from the office, but even with hiccups the staff have been professional and friendly. Thank you, Gem! You're the best, Nick!
great guy! vaery talented and professional
Joseph (Junior) from GEM Plumbing & Heating came out to do a check on our HVAC system for this season. He was very thorough, knowledgeable, and honest. Our system is in great shape after 16 years. Thank you Joe!!! We were on a contract plan, which was very reasonable, so we paid nothing at the time of service.
Our tech was Joseph (junior), Incredible experience came out the same day.Billed me for the service. Exceptional diagnostics, developed a number of options to fix the problem. We called four other places.First three never showed one showed and walked away, without figuring anything out. Our A/C has been out for 6 wks waiting for people to not show up. YOU ABSOLUTELY MUST CALL GEM FIRST
GEM responded very quickly. I was out of state when my tenant called stating the A/c system wasn't working. I called GEM to see if they would be willing to help me. I didn't have an account with them but they were more than willing to assist me with my broken A/C system.
Nick the technician was very knowledgeable and worked with me while I was out of state and with my tenants. He articulated very well, explaining all the issues, what the repair process would involve and the cost. There were no surprises. My tenants informed me that Nick was terrific !
Nick got the system up and running. Overall, it was a very positive experience and I would highly recommend GEM to anyone.
Great service. Timely response and got the job done. It’s on the pricey side but that’s expected given their quick response time. Joe was particularly good and have had him out twice on our property. Thanks!
From beginning to end the experience was amazing. It started with my man Walter who calmly with humor explained the process and my guys Ben and his partner who took cared of me and my family. They were professional and very knowledgeable about the process. Their patience when not finding my well was welcome. Awesome job
Thank you
The people are nice, punctual, pleasant.
And best of all great prices. I'm very happy with the service.
I was very impressed with Dory . He was extremely knowledgeable and very helpful.

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.
