Eric Governor from GEM came to my house today. I was very overwhelmed with the electrical issues I was having and he took his time explaining everything to me and what my options were. He didn’t leave until I understood what was needed. They were very nice and made me feel comfortable.
Help with well for irrigation system.
Cory was great. Fixed my problem in no time.
Was able to receive last minute, same day service from Abe and Logan. They were prompt, courteous and saved us a boat load of money. They found our tub leak easily and took care of it immediately allowing us to choose the repair option that was in our budget. Thanks very much!
Every person I dealt with at GEM was very professional and very pleasant. No long wait for the house call or the installation.They installed my three mini-splits and condenser in under 7 hours and cleaned up after themselves. The entire team of four men knew exactly what they needed to do. I would highly recommend them.
Excellent Service
I had my A/C go down on a 90° Friday. GEM sent David Salvatore to my house same day, and he was back first thing Monday morning with the parts to repair. He was an honest gentleman and a clean worker. He even found me a first time customer coupon to save me a few dollars. Are they priced a bit higher than some other companies? Yes, they are. But my existing company, Mutual Engineering, wasn’t even going to come for a diagnosis for a week! This is a perfect example of you get what you pay for. In addition to this condenser repair, David showed me maintenance that I should have been doing on a separate mini-split system installed by my now previous company. Mutual Engineering never informed me of this requirement. Bottom line is when it’s extreme heat or cold and your HVAC goes down, you want service quickly. I got that, and it was worth every penny.
Outstanding service Brian … Thank you so much for fixing my electrical problems with such accuracy and professionalism!!
Great professionals
Bill & Anthony did a thorough job on my HVAC system maintenance call. Pleasant, friendly, & knowledgeable. Thank you both!
We discovered a leak under our kitchen sink and as luck would have it, we had company coming to our house the following day. A neighbor gave me the name and phone number to GEM Plumbing. They came to our rescue and their guys were here the following morning, right at the promised time. We were very happy with their two guys and all was fixed within a few hours. Thank you so much!!!!!!
Service was outstanding done in a timely fashion clean neat and professional a little expensive
Steven was great to work with and explained the issue we were having very well.
Edward was great. My mother was having a drainage issue. Other companies have come in and charged her money and not fixed the problem. Edward got down to the root of the problem and fixed it for us. Response time is quick. I booked the appt on Tuesday evening they were there Wednesday morning. In the past my husband and I have used GEM for an emergency where we called at 7am and they were there by 9 same day. Obviously those things cost money, but it is very reasonable for what you are getting. I would absolutely recommend GEM to family and friends.
Excellent service, soup to nuts 24/7!
Service tech was exceptional Joe Oxford
Very quick service! Answered the call had someone come same day for a quote next day they were able to install! Impeccable service
I had a water leak in the AC unit and while they were here also found out that the capacitor was old and needed to be changed to get to right cooling temperature.
A little pricy , l paid $750 for a new capacitor and removal of some debris in the water collector in Ac unit.

But it still great , since they showed up as same day appointment and fixed everything.
Nicholas was very professional and did the job quickly.
The service was great!! The technicians were very nice, professional and polite. They explained everything and did their best to help us. Thank you!
The technician John Pete was
Very thorough and professional. He identified a problem unrelated to the service call and took care of it.
Nick is really excellent at explaining the issue with my system
and articulated solutions perfectly. Excellent work!

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.
