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!

Alec and Scott made quick work of what turned out to be a simple solution. Very efficient, pleasant and explained the issue and recommendation clearly.
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 Holbrook

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 Holbrook.

Certain rooms feel uncomfortable while others stay cool? This inconsistent performance wastes energy and disrupts your comfort throughout your property. Uneven temperatures indicate your system can’t distribute cooling effectively anymore. For Holbrook’s single-family homes, this often signals equipment that no longer handles the cooling load properly. Modern replacement restores balanced comfort in every room.

When you’re scheduling AC repairs every season, you’re investing in equipment that’s fundamentally worn out. Repair costs accumulate without solving underlying problems. Aging systems develop cascading issues where fixing one component reveals another failing. Air conditioning installation in Holbrook ends this frustrating cycle and delivers the dependable cooling your Norfolk County home deserves.

Most air conditioners deliver reliable performance for 12 to 15 years before efficiency naturally drops and problems multiply. Systems beyond this age cost more to operate and maintain than they’re worth. When your cooling equipment passes 15 years, replacement typically makes better financial sense. Contemporary systems incorporate technology that achieves superior cooling with dramatically reduced energy consumption, lowering monthly costs for Holbrook homes.

Grinding, squealing, or banging sounds reveal serious mechanical problems developing inside your equipment. These noises signal deteriorating components or escalating stress that worsens with each cooling cycle. What starts as occasional noise typically accelerates toward complete breakdown. Replacement solves these issues permanently while giving you quiet, reliable cooling backed by modern technology and warranty protection.
