The service was good.Aiden was very good. It’s just they said they were on there way 2hrs and30 min they finally arrived. Waited all afternoon
The 2 service men were on time, assessed the problem, diagnosed the issue, came up with a plan and offered several solutions for fixing our mini split. They took pictures, tried clearing out mice debris , attempted to get the outside machine to work ( apex 2 hours) Alas a no go, so we decided to scrap it and go with baseboard heater for the room over the garage. Up front information and pricing , no nonsense. Affable techs and so far great service.

I was thoroughly impressed with the superb HVAC maintenance service I received from David Santiago and trainee, Kevin today! Before David and Kevin arrived I was very disappointed with having had my original service date rescheduled to what I thought were spurious reasons? In fact David and Kevin arrived after the designated rescheduled date and time today. GEM's communication was excellent throughout and their people seemed genuine and concerned. When David and Kevin arrived it turned the whole situation around. They could not have been more professional and knowledgable! I am now firmly committed to GEM and their Home Comfort maintenance program.

We just had our heating system replaced. We went from forced hot water system to a central heating and air conditioning system done by GEM plumbing and heating company We had Omar and Michael work in our home for 5 days they installed all the ductwork, the furnace and the condenser. These guys were very professional, kind, clean and informative throughout the whole install every day they explaind what they did and what is the expectation for the next day. Today was the last day they walked me through the whole system, how to change the filter how to operate the new thermostat and what to look for when things are not working properly. I say thank you to the whole team from planing to done, all went great to expectations

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.
