I am very pleased with ALex's service. He is knowledgeable and polite.
The technician arrived. He came in and diagnosed the problem with my ductless system. He was able to get my system functioning, even though he didn’t have the pot needed to be replaced so temporarily we can run the system as it is he did he did his job by diagnosing the issue and doing a temporary fix?
I called GEM for a weekend, short notice pipe repair, and everyone was great from Hendry who I spoke to on the phone, to the two technicians Alec and Danny. They worked quickly, communicated clearly, and worked with me to come up with a solution I was happy with the price and result of. I would definitely call them in the future when things pop up.
Can’t say enough good things about Gem Plumbing and Thomas in particular. I easily got a came day appointment, Thomas the tech was here in the agreed upon window, provided 2 alternative estimates and once we selected, he completed the job right away – no need to make another appointment and come back another day. Great work, and even better service!
Chris A diagnosed my tankless water heater problem and repaired it quickly and efficiently. He answered all my questions with clear answers and was very helpful in alleviating any of my concerns. He gave excellent service!
Fast and knowledgeable service technicians.
William and Mark were excellent! They explained everything that they were doing and included us through the whole process. Would recommend them highly.
Very prompt and professional service!
The service provided by Mark and his partner was incredible. They took the time to explain all details of the situation and even helped make a call to a remediation company. They cleaned up after themselves and were very easy to discuss the repair process with.
Always a pleasure, professional expert service. Solving any problem simple or difficult!
Came even late at night to make sure we had working air conditioning
The team that installed the unit (Luis Herrera Mezquita Et al) was very professional and explained things thoroughly. I would highly recommend them.
Great customer service and understanding with us, and answered all our questions.
Knowledgeable technician attended to services thoroughly and had answers to all questions. Also helped with moving some furniture to ensure he could have enough working space. Very well done!

. GEM came for heat pump ac semi annual maintenance
As always very pleased to have GEM for all of my plumbing and electrical needs!
Thank you GEM
Was very impressed with Gems
Tech who was able to repair our AC units during our first real heat wave.
Hope to do business with Gem at our new home soon
Thomas from GEM came out today for my annual air-conditioning service, and I couldn’t be more impressed. He performed a thorough inspection, topped off all the necessary fluids, checked and adjusted my filters, and made sure everything was running smoothly and efficiently.

What really went above and beyond was that he noticed a hornets’ nest growing next to my air-conditioning unit and took care of it for me on the spot. That was something I hadn’t even realized needed attention, and it saved me from a potentially unpleasant surprise later on!

Thomas was professional, knowledgeable, and incredibly helpful throughout the entire visit. It’s rare to find someone who pays such close attention to the details and takes such pride in their work. GEM is fortunate to have him on their team. Thank you, Thomas, for the outstanding service!
Technicians were highly qualified. Very knowledgeable and professional. Respectful towards me and my home. Completed installation with in timeframe and cleaned up the areas they worked in. My issue is with whoever issued the system’s equipment. After 6 hours of working the technicians discovered they had been given the wrong system until! Resulting in them having to return for another 6 hour work day! This resulted in an additional day of inconvenience for myself and my family. No one from the Gem administration/management team has contacted me to apologize or offer reconciliation. I am happy with the product and the performance of the technical staff. But not with the treatment from management.
We had a tree branch fall and take out all of our electric equipment. GEM answered immediately and got someone out quickly. Mike Alberto got the job done quickly and explained everything as he went along. Great job!


How to Know When You Need a New Water Heater Installed

Not all water heater issues mean you need to replace the system.

Some can be repaired, while others will require an entire replacement. Keeping yourself aware of the most common signs you need water heater replacement in Boston can help you make the right choice for your home.

Water heaters will usually last between 8-12 years before needing to be replaced. If your water heater is at the older end of this range or even beyond it, it’s likely losing efficiency and could fail at any time. Replacing it now can help you avoid unexpected breakdowns and ensure consistent, reliable hot water. If your system is aging, water heater replacement in Boston is a smart investment.

Even small leaks around your water heater can signal serious internal damage, often caused by corrosion or a failing tank. Ignoring these leaks can lead to water damage and mold growth, so it’s best to schedule new water heater installation in Boston before a minor issue turns into a major problem.

If you’ve noticed your utility bills creeping up without increased usage, your water heater may be losing efficiency. Older systems need more energy to heat the same amount of water. For many Boston homeowners, upgrading to a newer, energy-efficient model means lower costs long-term.

When your water never seems to get hot enough or fluctuates in temperature, it’s a clear sign your system is struggling. Over time, sediment buildup and worn-out heating components reduce performance, making water heater replacement in Boston the most reliable fix.

We Install All Types of Water Heaters in Boston

Looking for a new water heater? You have a few options to choose from, each coming with its own set of unique benefits.

GEM can help you find and install the right water heater for your home, whatever it may be. Here’s a look at the types of water heaters we install in Boston:

As the name implies, tankless water heaters don’t rely on a tank to constantly heat the water within. Instead, they heat water as needed. Whenever you turn on the hot water, cold water flows through a heating element that instantly warms it before it reaches your faucet or shower. This on-demand process provides endless hot water, saves energy, and takes up far less space than traditional tank models. GEM installs tankless water heaters in Boston homes looking for efficiency and space savings.

Traditional water heaters are built with large storage tanks that are constantly heating the water within. This makes sure hot water is ready whenever you need it. These systems are dependable, affordable to install, and available in multiple fuel options, making them a popular choice for many Boston homeowners seeking reliable, consistent hot water for their entire home.

Hybrid water heaters, also known as heat pump water heaters, combine the best features of traditional and tankless systems. They use advanced heat pump technology to pull warmth from the surrounding air to heat the water, reducing energy use while still storing a supply of hot water for immediate access. GEM installs hybrid water heaters for Boston homeowners looking to maximize efficiency and take advantage of available rebates.

Frequently Asked Questions

What’s the right type of water heater for my home?

The right water heater depends on your household size, hot water usage, and energy preferences. GEM’s experts can assess your needs and recommend the best traditional, tankless, or hybrid system for your home.

How long does it take to install a water heater in Boston?

Most water heater installations can be completed in just a few hours. Larger or more complex systems, such as tankless models, may take a bit longer to ensure proper setup and testing.

How much energy do new water heaters use?

Modern water heaters are designed to be far more energy-efficient than older models. Tankless and hybrid systems, in particular, use significantly less energy because they heat water on demand or recycle ambient heat.

How long do water heaters last?

Traditional water heaters typically last 8–12 years, while tankless and hybrid models can last up to 20 years or more with proper maintenance. Regular tune-ups can help extend the lifespan of any system.

Can I install a new water heater by myself?

Installing a water heater yourself is not recommended due to safety risks and code requirements. A licensed professional from GEM will ensure your water heater installation in Boston is done safely, efficiently, and in compliance with local regulations.
