I was not a service call. It’s just a yearly check up on the air conditioner. I did not meet Thomas personally, but my wife said he was very nice man. you must’ve needed a garden hose for something. I noticed it was moved, but it was wrapped very nicely and put back where where he found it. I appreciate that. overall, we were very pleased with the service. Thank you.
Outstanding
Extremely happy
fantastic technician and service!
Great company to work with! Good communication, availability and the plumbers who came to pull a gas line were professional. Would definitely use their services again.
We received great service and happy with the results!
Tony and Kevin were great, very professional and very knowledgeable- they listened to what I thought was going on, started there and quickly solved the A/C airflow issue. In this day and age and how expensive everything seems to be it was refreshing that Tony seemed very aware of pricing and as a result of their experience and efficiency make the bill very reasonable
Aaron was knowledgeable and extremely helpful
Technicians Steve Gray and Chase were Outstanding in every detail from presentation to knowledge , expertise and commitment to resolving my problem. I am a very please customer and I just need to say Steve and Chase represent your company extremely well. I will continue to be a very loyal customer. Thank you
Xavier and Mike did an excellent job.
We were very happy with the Service! Jacob and his “understudy” showed a very professional and efficient service. Jacob seem to be very experienced, and knowledgeable, and can think outside of the box. For over 20 years every time we had the boiler serviced, louvre was recommended as a solution for the low air supply.. Jacob saw the unused 4 inch dryer duck which is already in place and with minor modification can provide more air, which I thought was a brilliant idea. Highly recommend this team to anyone!
Nicholas from GEM was very informative and fixed our problems and gave good advice. Thank you!
Generator maintenance. Excellent in all respects.
Douglas is terrific!
Orlando and Marcello are true superstars of your business! Polite, very quick at helping me fix my problem with my Plumbing. The whole process from start to finish was handled beautifully thank you so much for making a stressful situation so much easier!

Excellent service! Gem Plumbing was professional, responsive, and arrived on time. They quickly identified the issue with the roof drain pipe, clearly explained the repair, and completed the work efficiently. The quality of the workmanship was excellent, and everything was left clean when the job was finished. I would definitely recommend them to anyone looking for a reliable plumber.
Excellent service with clear explanation. On time, friendly professional communication. Issues resolved with creativity!

Joan handled our house today. Great technician.
Hands down the best service, communication is top notch. My Ac and furnace needed to be replaced and I must say Alecs Reyes and team were amazing, polite and professional and informative every step of the way. I highly recommend Gem.

Efficient professional and quick service excellent!! Thank you Eric
Devontay Vaz and his colleague did an excellent job servicing our scheduled maintenance on our Heating and Cooling Mini Split system which is part of our Maintenance Plan. They took the time to explain the process from start to finish. They also made sure to explain the future unit maintenance after the summer season, which we found VERY helpful. We have been members of Gem Heating and Plumbing for years now. As always, the technicians were polite, professional, and knowledgeable about their work. With life being busy, Gem always call us as a reminder to make these scheduled appointments. Thank you, Gem Plumbing!!
John is great.


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.
