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!

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.


How to Know When You Need a New Water Heater Installed

Don’t get caught by surprise when your water heater fails.

If your Lexington home’s water heater shows these symptoms, it may be time to consider replacement. GEM can help you decide.

Most water heaters last 8 to 12 years with proper care. If yours is in that age range or older, efficiency has dropped and failure could come any time. Replacing now gives you control over the timing.

Rust or corrosion visible on the outside of your water heater usually means worse conditions inside. Once corrosion sets in, tank failure is a matter of time. Replacing before a leak occurs prevents water damage.

If showers are getting cut short or you’re running out of hot water during normal use, your tank may be losing capacity. Sediment buildup and aging components reduce how much hot water the system can deliver.

Metallic or sulfur odors coming from your hot water indicate problems inside the tank. Bacteria growth or a failing anode rod are common causes. In older systems, these issues often mean replacement is the better path forward.

We Install All Types of Water Heaters in Lexington

Every home has different hot water demands. GEM helps you choose the right water heater based on your household size, space, and budget.

Here’s a look at the types of water heaters we install in Lexington:

Tank water heater installation in Lexington is the tried-and-true choice for most households. These units store 40-80 gallons of heated water, ready whenever you need it. Tank models work with gas or electric power, install affordably, and deliver dependable performance for families running showers, laundry, and dishes throughout the day. For consistent hot water without surprises, a properly sized tank water heater gets the job done.

Tankless water heater installation in Lexington appeals to homeowners who want endless hot water and energy savings. These compact units heat water on demand as it passes through, so you never run out mid-shower. Tankless systems mount on walls, freeing up floor space in tight basements or utility closets. GEM installs tankless water heaters in Lexington homes looking for efficiency and long-term value.

Whether tank or tankless, today’s high-efficiency water heaters cut energy use without sacrificing performance. GEM installs ENERGY STAR certified models that qualify for rebates and lower your monthly utility bills. We’ll help you weigh upfront costs against long-term savings to find the smartest choice for your Lexington home.

Water Heater Installation FAQs

How long do water heaters typically last?

Standard tank water heaters last 8 to 12 years with proper maintenance. Tankless units can last 20 years or more. Factors that affect lifespan include water quality in your Lexington home, how hard the unit works, and whether maintenance tasks like flushing and anode rod replacement are performed. GEM’s Home Comfort Club helps extend equipment life through regular maintenance.

Does Mass Save offer incentives for water heater replacement?

They do, for qualifying high-efficiency models. The program offers rebates that can make upgrading to efficient equipment more affordable for Lexington homeowners. GEM helps you navigate the options and choose equipment that qualifies for maximum savings. We’re familiar with the current programs and can guide you through the application process.

How quickly can GEM install a new water heater at my Lexington home?

Most installations are completed in a single visit, typically two to four hours for a straightforward tank replacement. Our technicians serving Lexington arrive prepared with equipment and parts to handle the job efficiently. We know you need hot water, so we work without unnecessary delays while still doing the job right.

Can GEM handle water heater emergencies in Lexington?

Yes. We provide 24/7 emergency service throughout Lexington and the Greater Boston area. If your water heater fails unexpectedly, leaks, or poses a safety concern, call us immediately. Our technicians can respond quickly to assess the situation and get your hot water restored as soon as possible.

Are high-efficiency water heaters worth the extra cost?

For most Lexington homeowners, yes. High-efficiency models cost more upfront but reduce monthly energy bills, often paying for themselves within a few years. Heat pump water heaters in particular can cut water heating costs by 50% or more compared to standard electric tanks. Combined with Mass Save rebates, the net cost difference shrinks significantly while the savings continue for the life of the equipment.
