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.

I had a great experience with my recent HVAC appointment. David the technician was punctual, polite, and very thorough while performing the annual maintenance of both our heating and cooling systems.

Joan handled our house today. Great technician.
Hands down the best service, communication is top notch. My Ac and furnace needed to be replaced and I must say Alecs Reyes and team were amazing, polite and professional and informative every step of the way. I highly recommend Gem. Update I also had them move my electrical panel which was not up to code and was the worst thing they have ever seen lol the team who handled the move was amazing once again fantastic work by the gem team!
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 You Need a New AC System

Recognizing when your air conditioner needs replacement helps you avoid uncomfortable breakdowns during Quincy’s warmest weather.

Pay attention to these indicators that it’s time to consider a new air conditioning installation.

When your system operates nonstop but can’t maintain comfortable temperatures, something has gone wrong. This pattern wastes energy, drives up utility costs, and leaves you uncomfortable in your own home. Quincy’s waterfront humidity makes cooling challenges worse for struggling systems. A new AC installation designed for these conditions becomes the most practical solution for your property.

A gentle hum when your system starts is normal. Loud grinding, persistent banging, or high-pitched squealing indicates mechanical problems that typically worsen with each cooling cycle. These noises usually mean worn components or mounting stress within your system. Replacing it with a newer, quieter model makes clear sense when sounds become disruptive.

Air conditioners generally function well for 12 to 15 years before efficiency naturally declines. Beyond this age range, systems lose both cooling capacity and energy efficiency even with regular maintenance. Contemporary technology delivers superior cooling while using less power. Replacing an older unit not only improves comfort but also provides the reliability of new, warranty-backed equipment.

Excessive moisture around your AC unit or musty odors when the system runs signal serious problems. These issues often indicate drainage failures or refrigerant leaks that compromise both performance and air quality. If your system produces these warning signs, replacement typically makes more sense than attempting repairs on aging equipment.
