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).!
Dory was friendly, respectful, and went above and beyond!

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.

Warning Signs It’s Time for AC Replacement in Somerville

These indicators tell you when investing in new equipment makes better sense than another repair attempt.

Watch for these signs that replacement makes financial sense.

Strong, steady airflow maintains comfortable temperatures throughout every room. When air movement feels weak even at highest settings, or when some areas get minimal cooling while others work normally, distribution problems have developed. This forces your system to operate longer while achieving less, increasing expenses without delivering adequate comfort. Professional replacement solves airflow issues and restores proper performance throughout Middlesex County homes.

Climbing utility costs despite unchanged usage patterns reveal declining efficiency. Component wear and aging produce this gradual performance loss. A technician should examine your system to identify causes and evaluate severity. Modern air conditioning systems deliver dramatically improved efficiency, consuming significantly less electricity while providing superior cooling. Replacement typically reduces monthly expenses substantially while improving comfort and reliability for years ahead.

Normal operation produces gentle background sounds. Persistent grinding, sharp squealing, or loud banging indicates internal problems developing. These noises signal component deterioration or mechanical stress intensifying with continued operation. When sounds grow louder with each cycle, installing newer, quieter equipment becomes the practical choice.

Your thermostat setting should deliver consistent comfort throughout your entire home. When specific areas stay warm despite proper settings, or when your system runs constantly without achieving desired temperatures, efficiency problems exist. Somerville’s many triple-deckers experience this frequently as aging systems struggle with multi-level cooling demands. These patterns waste energy while reducing comfort, making new AC installation the practical long-term solution.
