Excellent work as always.
MELISSA PALANZA
Great Service and results!!!!!
I came home on Sunday after working all day and found my kitchen sink full of sewerage. Called Gem from a list because I recognized the name from the trucks I have seen around town. They actually answered the phone at 6:30 on Sunday night. The guy was great very helpful (I know nothing about plumbing) took all my info put me on hold then came right back to say they could have somebody out to me that night and that they would call me. Within the hour they called and said be there in 15 minutes and they were. Guy was great answered all my stupid questions, gave me a price before starting work. He was very knowledgeable and friendly. ( even when I accidentally flushed while he was working!) I had roots in sewer line going to street he was upfront with what was done. About How long I could expect it to last and what I needed to do to fix problems. He even found a leaking pipe I need to fix in bath! When I asked for exact prices for other fixes he either had them or could refer me to who did. I thought the price was a bit steep but it was a Sunday night! And when I checked with other places found they were pretty normal if you could even get service on Sunday night!

Services were very good. Technician was very polite, respectful and knowledgeable. I was very pleased.
Lawrence Galardi
Anthony was proactive, thorough, and responsive for what was an unexpected rush repair.
Amanda Bishop
I scheduled my first HVAC Maintenance appointment and Emanuel Q came out. Emanuel was great! He answered all of my questions and explained everything he was doing. While he was outside he noticed the wiring for the AC unit wasn't wired correctly and coordinated with his supervisor to come back and install an electrical whip a few days later. I didn't have to do anything with the scheduling, he took care of everything! I'm very happy with the service received!
Thomas Ladd
Solved our problem! Terrific! Patient and polite technician.
Gem has always been my lifesaver and yesterday they came through again. When GEM came yesterday for the annual boiler cleaning they discovered that my boiler was leaking carbon monoxide gas. It had not been leaking the year before so carbon monoxide leaking from your burner. Itโ€™s like a tire thatโ€™s going flat in the air is coming out. It only gets worse. They gave me an estimate on replacing it, I did some research and they said that they couldnโ€™t install it the next day. The price was in line with everything I had researched and the Bernar rated very high on Trustpilot as did the warranty. Having worked with GEM before, I trust them and I made the deal. Today two men arrived two more came then the Electrician.They got the old burner out they got the new burner installed. They cleaned up the basement and I now have heat and no carbon monoxide.Thanks for being there again GEM.

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.
