In a world where you call HVAC companies and either get no answer, an AI receptionist or a human who takes all your information just to tell you they can’t service you until next week, these guys were a breath of fresh air! Same day service. Fair price. Incredibly kind people from the receptionist to the service worker. Thank you guys!

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.

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.
