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

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!
Cory was very knowledgeable and respectful.
The technical aspects of the job he explained so I could understand.

I had a great experience with my recent HVAC appointment. David the technician was punctual, polite, and very thorough while performing the annual maintenance of both our heating and cooling systems. He explained what was doing, reviewed the results of the tests that were done and provided estimates for potential future component replacement.

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. Update I also had them move my electrical panel which was not up to code and was the worst thing they have ever seen lol the team who handled the move was amazing once again fantastic work by the gem team!
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

When repair isn’t the right answer anymore.

These warning signs are telling you something important. GEM helps Portsmouth homeowners understand the message.

Water heaters have a limited service life. Once yours enters the 10 to 12 year range, efficiency drops and the risk of sudden failure climbs. Replacing before breakdown lets you plan the upgrade on your schedule.

Water pooling around the base of your water heater indicates internal failure. Once a tank starts leaking, it cannot be repaired. Replacing it quickly prevents water damage to your home.

When hot water swings between too hot and lukewarm without pattern, your water heater is struggling. Failing thermostats, sediment buildup, or aging heating elements can all cause this. If basic service doesn’t solve it, water heater replacement in Portsmouth is the answer.

A single repair on a younger system makes sense. But if you’ve called for service multiple times in the past year or two, those costs are adding up. At some point, water heater replacement in Portsmouth becomes the better investment.

Water Heater Installation FAQs

How does GEM determine what capacity water heater my household needs?

We look at several factors specific to your Portsmouth home: how many people live there, number of bathrooms, whether you have high-flow showerheads or standard fixtures, and when your peak usage occurs. A household where everyone showers in the morning has different needs than one where usage is spread throughout the day. We also consider your existing infrastructure since upgrading from a 40-gallon to an 80-gallon tank may require electrical or venting modifications.

Does Rhode Island Energy 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 Portsmouth 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.

I’m not sure what size tank my family needs. How do you figure that out?

GEM’s technicians assess your household’s hot water demands during the consultation. We ask about family size, bathing habits, whether you run the dishwasher and washing machine simultaneously, and what your busiest times are. For Portsmouth’s colonials, farmhouses, and waterfront estates, we often recommend 40 to 50 gallon tanks for families of three to four, but we customize recommendations based on your actual usage patterns rather than applying a one-size-fits-all formula.

What’s the difference between gas and electric water heaters?

Gas water heaters typically heat water faster and cost less to operate if you have natural gas service. Electric models are simpler to install and maintain, and don’t require venting. Heat pump electric models are highly efficient but need adequate space around them. For Portsmouth’s colonials, farmhouses, and waterfront estates, the best choice depends on your existing utilities and installation location. GEM can advise which makes sense for your specific situation.

How long does water heater installation take in Portsmouth?

Most standard tank replacements are completed in two to four hours. GEM’s technicians arrive with a fully stocked truck, so we have the fittings, connectors, and parts needed to handle typical installations without delays. If your Portsmouth home requires modifications like updating old galvanized pipes, relocating the unit, or upgrading electrical service, the job may take longer. We’ll give you a realistic timeframe before we start.
