Nice people, quick to respond and knowledgeable. Highly recommend them for emergencies. William T. was great, thank so much
First maintenance on our Generac. All went very smoothly!! Arrived within timeframe provided and even informed on actual arrival that day!
Very polite gentleman who went right to work, provided an update once maintenance was completed and explained basic process performed.
David S, our GEM technician was on time, respectful of our home and provided us with a thorough explanation of our GEM service contract and the scope of work completed and recommended. I would highly recommend him again!
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.
Awesome service and friendly guys.
My name is Fred Brundage West Dennis MA
I had one of Gem Heating and Plumbing plumbers Christopher Rogan repair two broken gas line on an emergency basis. Chris was very professional, courteous and willing to make sure that the inspector was available once the job was completed. I was on a tight schedule to open the house. Gem Heating and Plumbing is a company that can be relied on.
Joan was very helpful – but his arrival was very delayed and communication was not great
They came over right away, diagnosed the problem and fixed it. Fast courteous service.
Chris from GEM arrived as scheduled and resolved a no hot water issue. I even got a GPS map for his truck to our location, and notified when he would arrive. No other company after several calls ( including one we have used for over 7 years would be able to help us for 10 days. With three women in the house that would not work.
Chris diagnosed and fixed our furnace which controls the hot water.
I will be using GEM in future for sure!
Excellent response, installation and knowledgeable services. Technicians were polite, prompt, professional, and kept us informed throughout the job. Would gladly use them for all future HVAC work and service.
Excellent knowledge followed by superior customer service
Jim was great! Pleasant, knowledgeable and helpful. He took the time to give me a few options and explained pros and cons. I am very thankful for his input and careful work! He replaced and upgraded faucets outside and new hoses to my washing machine!

Nick was great! He was presented with an unfixable AC problem. I was so impressed that he found this little piece of broken plastic tha caused such a water leak. He was very helpful in explaining options and estimate cost. He also climbed high up on a ladder inside and out to clean my filters. I’m so thankful.

How to Know When You Need a New Air Conditioner Installed

Understanding the signs to install a new AC system before it breaks down can save you from serious frustration and discomfort during the hottest days of the year.

Here’s when we recommend considering a new AC installation.

You have an ideal temperature you’ve set on your thermostat, and your cooling system should be able to reach and maintain it consistently throughout your home. When certain rooms feel warmer than others or your system runs nonstop without keeping up, it’s a clear sign your air conditioner may be losing efficiency.

Over time, this can lead to higher energy bills and reduced comfort, making a new AC installation the best long-term solution for your home.

When your system turns on and begins a new cycle, you may hear your air conditioner turn on and produce a gentle hum; that’s normal and doesn’t signal issues. When you start noticing loud bangs, rattles, or grinding sounds, though, it’s often a sign that something isn’t working as it should.

Unusual noises can point to wear and strain within the system, which may worsen over time. If your AC is getting noisier with each cycle, it’s likely time to consider replacing it with a newer, quieter, and more efficient model.

Energy bills typically climb as system efficiency drops. This can happen over time due to wear and tear or system aging. Your technician should inspect your system and determine the cause and extent of the issue.

New air conditioning systems are designed to operate far more efficiently, using less energy to deliver better cooling performance. Upgrading your AC can significantly lower monthly utility bills while providing more consistent comfort and peace of mind for years to come.

Air conditioners typically have lifespans of around 15-20 years. As they age, they naturally become less effective and efficient. If your air conditioning unit is beyond 20 years of age, having it replaced with a newer model can save you money on both energy and repair costs in the long run.

Modern systems are built with advanced technology that improves cooling performance while using less power. Replacing an outdated unit not only enhances comfort and efficiency but also gives you the reliability and peace of mind that comes with a brand-new, warranty-backed system.

We Install All Types of Air Conditioners in Boston

GEM is here to help your home stay at the right temperature all summer long, no matter what type of system you count on to do so.

Here’s a look at the types of air conditioners we install:

The most common type of cooling system in Boston, central air conditioners are extremely reliable and effective. No matter how high the outdoor temperatures climb, central AC systems deliver consistent, even cooling throughout your entire home. They’re designed to maintain comfort across every room while keeping humidity levels in check.

GEM installs and services high-quality central air systems that are energy-efficient, durable, and tailored to your home’s layout.

Installing a heat pump is an energy-efficient way to keep your home cool during Boston’s hot summer months. Instead of generating cold air, they move heat from inside your home to the outdoors, maintaining a comfortable indoor temperature with less energy use.

The AC technicians at GEM can install modern heat pump systems designed to provide reliable, consistent cooling while keeping energy costs low.

Ductless mini-splits offer flexible, efficient cooling without the need for traditional ductwork. They’re perfect for individual rooms, additions, or homes where installing ducts isn’t practical, delivering precise temperature control wherever you need it.

GEM provides expert ductless mini-split installation and service, helping Boston homeowners enjoy targeted comfort and quiet, efficient cooling throughout the summer.
