Joe did a wonderful job of coming to check my HVAC system prior to this coming summer. I was extremely pleased with his efficiency and the timely manner in which it was accomplished. Thank you Joe!
Always reliable and courteous service! We have relied on GEM for regular maintenance, repair services, plumbing, new HVAC installation, and even shower installation. We feel we can cou t on GEM to be there when we need them and always perform great work.
Excellent service, highly recommend
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.
While the repair was simple, Stephen and Eric were very professional and courteous.
We were very pleased with Gem’s air conditioner maintenance service. Dory and his team did an exceptional job. They explained what they were doing and shared helpful information about maintaining our HVAC system.
Joe, the service person who came to fix our water heater, was amazing. Calm, expert, efficient and best of all very interested in showing me (and teaching me about) what was going on. It's really important to be knowledgeable about your own home. The problem has been fixed and I also know what to look out for in the upcoming months and years. The service (and parts) weren't cheap. Phew. But I have a good sense that the good service that Joe provided will ultimately save us money in the long run as we care for our system.
great service again
Jared was great, super knowledgeable super personable, easy to work with.
Joe Kiff from GEM Plumbing & Heating came out for our annual central air system checkup. He arrived on time, clearly explained what he planned to do, walked me through everything afterward, and offered helpful suggestions for a few improvements. Overall, excellent service!
Outstanding job from response within 24 hours, to assessment within 48 hours and full job complete within 72 hours, all within a reasonable budget. Great team of Chris, Baxter and Joe. Couldn’t be more pleased with their work or them as friendly professionals.
I called upon Gem Plumbing for a washer / dryer install, in my condo. I needed water pipes moved and shut off valves installed – the whole nine yards. Gem sent Walter P to give an estimate and to do the job.
Walter in a fine young gentleman, very kind and courteous. He explained the work that needed to be done. He came in and did the job. Now I have a full laundry set up in my condo. Thank you Walter so for a Job Well Done. I will highly recommend Gem Plumbing to anyone who needs expert service. And I will certainly call upon them for any services I need in the future. Thank you.
Great work by all of the GEM workers at our house! Had a somewhat difficult situation to resolve and they got it done!
Timothy was great. Friendly, knowledgeable and professional
Bob was a very nice man. Fixed our ac and did the yearly maintenance. It was a pleasure meeting him.
Mason did an excellent job replacing my hot water heater. He was knowledgeable, professional, and personable. I was extremely happy with his service.
Very happy with the technician that came to our house- very thorough and informative.
Friendly, courteous and professional service. Happy to have them as my service provider.
Work was completed professionally and completely. Nick offered ideas and alternative approaches and recommendations. They responded quickly.
Mr. Liu and his GEM in training arrived on time and with phone calls that let us know their efforts were booked after our appointment. But…they took all the time they needed to assess what could have been a messy reinstall of a bath light/exhaust fan in a 1955 house. Although adequately warned that something other than pretty could happen, they made surgical cuts to enlarge the ceiling hole with minimal degradation of the ceiling. Despite the number of sawzall blades they’d used, we
were all smiling when we turned the fan on for the first time. Another successful visit by the GEMs.
(As always, my only hesitation in using GEM for future projects is the pricing process.)
The guys were professional and provided education on what was needed to fix our issue. Thanks to both of them!
This is third time we've used this service and they responded to an emergency a little outside their expertise when no one else would. They are quick, professional and knowledgable. Very responsive and worth the money!
Great communication and prompt service. Tyler was polite, knowledgeable and professional.
Efficient, friendly guys replaced my whole HVAC system in less than a day.
From the very beginning everyone we dealt with at GEM were professional, knowledgeable and helpful. The installation process was as promised and was efficiently completed. An outstanding job by all. Thank you.


How to Know When You Need a New Water Heater Installed

Recognize these signs before your water heater quits.

Watch for these warning signs in your Cambridge home. When they appear, GEM can help you determine whether repair or replacement makes more sense.

Most water heaters last 8 to 12 years. If yours is approaching or past the 10-year mark, efficiency has likely dropped and the risk of failure increases. Replacing now avoids unexpected breakdowns and the inconvenience that comes with them.

Discolored hot water or visible rust on the tank exterior signals corrosion inside. While sometimes caused by aging pipes, rust in hot water that clears up after running usually points to the water heater itself. This problem only gets worse.

If your water heater used to recover quickly between uses but now takes hours, age and sediment are catching up. When flushing no longer helps, the system is losing capacity. Replacement restores reliable hot water.

For gas water heaters, a pilot light that keeps going out indicates a failing thermocouple or other component. While sometimes repairable, recurring pilot problems in older units often point toward replacement being the better investment.

We Install All Types of Water Heaters in Cambridge

The right water heater depends on your household size, hot water habits, and available space. GEM helps you find the perfect match.

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

Tank water heater installation in Cambridge 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 Cambridge 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 Cambridge 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 Cambridge home.

Water Heater Installation FAQs

What’s the difference between gas and electric water heaters?

Gas water heaters typically heat water faster and cost less to operate if you have natural gas service. Electric models are simpler to install and maintain, and don’t require venting. Heat pump electric models are highly efficient but need adequate space around them. For Cambridge’s historic row houses, condos, and multi-family buildings, the best choice depends on your existing utilities and installation location. GEM can advise which makes sense for your specific situation.

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 Cambridge 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.

When should I start thinking about replacing my water heater?

Once your water heater approaches 10 years old, it’s wise to start planning for replacement even if it’s still working. That way you can research options, budget accordingly, and replace on your schedule rather than in an emergency. Many Cambridge homeowners find that proactive replacement avoids the inconvenience and potential water damage of an unexpected failure.

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 Cambridge 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.

Should I get a gas or electric water heater for my Cambridge home?

That often depends on what’s already in your home. If you have natural gas service and existing gas lines to your water heater location, a gas unit typically offers faster recovery times and lower operating costs. If you’re electric-only, an electric water heater or heat pump model avoids the expense of running new gas lines. GEM evaluates your Cambridge home’s infrastructure and helps you choose the option that makes practical and financial sense.
