I was not a service call. It’s just a yearly check up on the air conditioner. I did not meet Thomas personally, but my wife said he was very nice man. you must’ve needed a garden hose for something. I noticed it was moved, but it was wrapped very nicely and put back where where he found it. I appreciate that. overall, we were very pleased with the service. Thank you.
Outstanding
Extremely happy
fantastic technician and service!
Great company to work with! Good communication, availability and the plumbers who came to pull a gas line were professional. Would definitely use their services again.
We received great service and happy with the results!
Tony and Kevin were great, very professional and very knowledgeable- they listened to what I thought was going on, started there and quickly solved the A/C airflow issue. In this day and age and how expensive everything seems to be it was refreshing that Tony seemed very aware of pricing and as a result of their experience and efficiency make the bill very reasonable
Aaron was knowledgeable and extremely helpful
Technicians Steve Gray and Chase were Outstanding in every detail from presentation to knowledge , expertise and commitment to resolving my problem. I am a very please customer and I just need to say Steve and Chase represent your company extremely well. I will continue to be a very loyal customer. Thank you
Xavier and Mike did an excellent job.
We were very happy with the Service! Jacob and his “understudy” showed a very professional and efficient service. Jacob seem to be very experienced, and knowledgeable, and can think outside of the box. For over 20 years every time we had the boiler serviced, louvre was recommended as a solution for the low air supply.. Jacob saw the unused 4 inch dryer duck which is already in place and with minor modification can provide more air, which I thought was a brilliant idea. Highly recommend this team to anyone!
Nicholas from GEM was very informative and fixed our problems and gave good advice. Thank you!
Generator maintenance. Excellent in all respects.
Douglas is terrific!
Orlando and Marcello are true superstars of your business! Polite, very quick at helping me fix my problem with my Plumbing. The whole process from start to finish was handled beautifully thank you so much for making a stressful situation so much easier!
Excellent work on a variety of household electrical needs. Service techs were professional, friendly, and all work done to high standards!
Excellent service! Gem Plumbing was professional, responsive, and arrived on time. They quickly identified the issue with the roof drain pipe, clearly explained the repair, and completed the work efficiently. The quality of the workmanship was excellent, and everything was left clean when the job was finished. I would definitely recommend them to anyone looking for a reliable plumber.
Excellent service with clear explanation. On time, friendly professional communication. Issues resolved with creativity!
Cory was very knowledgeable and respectful.
The technical aspects of the job he explained so I could understand.

Efficient professional and quick service excellent!! Thank you Eric
Devontay Vaz and his colleague did an excellent job servicing our scheduled maintenance on our Heating and Cooling Mini Split system which is part of our Maintenance Plan. They took the time to explain the process from start to finish. They also made sure to explain the future unit maintenance after the summer season, which we found VERY helpful. We have been members of Gem Heating and Plumbing for years now. As always, the technicians were polite, professional, and knowledgeable about their work. With life being busy, Gem always call us as a reminder to make these scheduled appointments. Thank you, Gem Plumbing!!
John is great.

Warning Signs It’s Time for AC Replacement in Cambridge

Your air conditioner sends clear signals when replacement makes more sense than another repair.

These warning signs tell you it’s time to consider new air conditioning installation in Cambridge.

Repeated service calls drain your budget while providing no long-term solution. Aging systems develop cascading problems where fixing one issue reveals another. You’re maintaining failing equipment instead of investing in reliable cooling for your Metro Boston home. Air conditioning installation in Cambridge ends this expensive cycle and delivers dependable performance you can count on throughout summer.

When cooling costs climb month after month despite stable usage, your system is losing efficiency. Age and component wear produce this gradual decline. What once cooled your home efficiently now struggles, consuming excessive electricity while delivering diminishing results. Modern air conditioning installation in Cambridge cuts energy consumption dramatically while providing superior cooling performance and long-term reliability.

Air conditioners generally perform well for 12 to 18 years before efficiency naturally drops and problems multiply. Equipment beyond this age costs more to operate and repair than modern replacements justify. When your system reaches 15 years, replacement typically delivers better long-term value. Contemporary systems incorporate technology that achieves superior cooling with minimal energy consumption, reducing both monthly costs and breakdown frequency for Cambridge homes.

Your air conditioner shouldn’t operate continuously just to maintain barely adequate temperatures. When your system runs all day but rooms stay warm, it’s revealing it can no longer meet your cooling demands. This constant operation wastes energy while failing to deliver proper comfort. Professional air conditioning installation in Cambridge provides properly sized equipment that maintains consistent temperatures throughout your home without excessive runtime.
