GEM plumbing recently installed a ductless minisplit system in my home. The installers did an excellent job. They were extremely knowledgeable, courteous, and patient. They communicated with me every step of the way and took the time to answer all of my questions. The system is working beautifully. If you are looking for a contractor to install a ductless minisplit system, I highly recommend GEM plumbing.
I do wish it hadn’t been so expensive, but I will say I really did feel like my technician understood what he was doing. He was knowledgeable and professional. He explained things well and I’d be happy to work with him again.

Both service calls to my house were with Nick, and I can't say enough good things about him. He's professional, courteous, communicative, and thorough.

great guy! vaery talented and professional
Joseph (Junior) from GEM Plumbing & Heating came out to do a check on our HVAC system for this season. He was very thorough, knowledgeable, and honest. Our system is in great shape after 16 years. Thank you Joe!!! We were on a contract plan, which was very reasonable, so we paid nothing at the time of service.
Our tech was Joseph (junior), Incredible experience came out the same day.Billed me for the service. Exceptional diagnostics, developed a number of options to fix the problem. We called four other places.First three never showed one showed and walked away, without figuring anything out. Our A/C has been out for 6 wks waiting for people to not show up. YOU ABSOLUTELY MUST CALL GEM FIRST
GEM responded very quickly. I was out of state when my tenant called stating the A/c system wasn't working. I called GEM to see if they would be willing to help me. I didn't have an account with them but they were more than willing to assist me with my broken A/C system.
Nick the technician was very knowledgeable and worked with me while I was out of state and with my tenants. He articulated very well, explaining all the issues, what the repair process would involve and the cost. There were no surprises. My tenants informed me that Nick was terrific !
Nick got the system up and running. Overall, it was a very positive experience and I would highly recommend GEM to anyone.
Great service. Timely response and got the job done. It’s on the pricey side but that’s expected given their quick response time. Joe was particularly good and have had him out twice on our property. Thanks!
From beginning to end the experience was amazing. It started with my man Walter who calmly with humor explained the process and my guys Ben and his partner who took cared of me and my family. They were professional and very knowledgeable about the process. Their patience when not finding my well was welcome. Awesome job
Thank you
The people are nice, punctual, pleasant.
And best of all great prices. I'm very happy with the service.
I was very impressed with Dory . He was extremely knowledgeable and very helpful.


How to Know When You Need a New Water Heater Installed

Some water heater issues can be fixed with a simple repair, but others mean it’s time for a full replacement.

Here’s how to tell when your Weymouth home needs a new water heater.

Water heaters typically last 8 to 12 years. Once yours approaches that range, performance declines and the chance of failure goes up. Replacing proactively means you choose when it happens.

Moisture around your water heater often signals a slow leak or tank corrosion. These issues only get worse over time. New water heater installation in Weymouth stops a small problem from becoming a flooded utility room.

If hot water temperatures vary unpredictably or the supply runs out faster than it used to, your water heater is losing capacity. Aging components and sediment buildup reduce performance over time.

An inefficient water heater uses more energy to produce the same amount of hot water. If your bills have crept up but usage hasn’t changed, your water heater may be the culprit. A new, efficient model brings those costs back down.

We Install All Types of Water Heaters in Weymouth

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 Weymouth:

Tank water heater installation in Weymouth 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 Weymouth 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 Weymouth 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 Weymouth home.

Water Heater Installation FAQs

What type of water heater is best for my home?

The right water heater depends on household size, hot water demand, and available space. Tank water heaters work well for most families and cost less upfront. Tankless provides endless hot water at higher initial cost. GEM evaluates your situation and recommends the best option.

How long does water heater installation take?

Standard tank replacements complete in two to four hours. Tankless jobs take longer, especially if your home needs electrical upgrades or gas line modifications. GEM provides time estimates before work starts.

How do I know if I should repair or replace?

Age is the biggest factor. Water heaters under 8 years old with isolated issues can often be repaired. Systems over 10 or showing multiple problems are usually better replaced. GEM provides honest recommendations.

Mass Save offers rebates on qualifying high-efficiency water heaters. GEM identifies eligible models and assists with the rebate process.

Does GEM remove the old water heater?

Yes. Removal and proper disposal are included with every installation.
