Excellent knowledge followed by superior customer service
Jim was great! Pleasant, knowledgeable and helpful. He took the time to give me a few options and explained pros and cons. I am very thankful for his input and careful work! He replaced and upgraded faucets outside and new hoses to my washing machine!

Nick was great! He was presented with an unfixable AC problem. I was so impressed that he found this little piece of broken plastic tha caused such a water leak. He was very helpful in explaining options and estimate cost. He also climbed high up on a ladder inside and out to clean my filters. I’m so thankful.

Employee was great. He explained what needed to be done and costs. Unfortunately, I had a leak in the AC line where it connected to a head unit on a system that I had installed by another company 4 years ago. All the refrigerant leaked out over that 4 year period. I feel this should have never happened and been found during their pressure test.
Anyhow, $3100 later, repaired. Just wished it hadn’t cost so much but not GEM’s fault. As far as the pricing, I have no idea.
Eric and the young lady were wonderful. They worked continuously and neatly all day
Michael M. from GEM was professional, knowledgeable, and courteous. He diagnosed the blockage problem and rectified it promptly. Five stars for his expertise!
David was a terrific through out the entire process. Great water filtration system installation and also great walking me through the process. Highly recommended.
Courteous, professional and a job well done. I will gladly refere and use Gem services again. Pricing was also responsible. Thank you
Friendly, very helpful and did a great job!
Dude was awesome, he knew his stuff and very professional
Bob showed up and was very professional and went out of his way to explain the problems being addressed with furnace and AC.
Nathan is very professional and knowledgeable. Highly recommend
Listened to my concerns and provided great customer service.
They do excellent meticulous work. The only reason I can’t give five stars is through no fault of theirs. They found the gas leak, but it would require ripping out more walls, so going with an electric range
We had Chris come out and fix a significant mini-split issue on a tight timeline. He did a great job on a complicated system, was super responsive, and we are very grateful for the excellent work.
David was an amazing representative of Gem. Explained everything in detail, very professional, and fixed our A/C issue.
Jim Dowdy replaced a 10 ft piece of cast iron pipe with PVC and I can’t say enough about him and Gem Plumbing. They came to my rescue over Labor Day weekend! I have used them in the past and will continue to. Job well done Jim.
Excellent response, installation and knowledgeable services. Technicians were polite, prompt, professional, and kept us informed throughout the job. Would gladly use them for all future HVAC work and service.
Thanks!
Great technician!
Dory came and repaired by air conditioner. He did an excellent job efficiently. Very pleasant I would love to have him again if needed.
Update! Just had John P from GEM provide maintenance on my central AC unit. He was fantastic! Explained everything and performed his work efficiently with great communication andcrespect for my home! He was just great! I appreciate being able to get an appt so quickly with GEM. It's so helpful to be able to schedule appointments around my availability and as a FT worker who commutes via rail, I value that scheduling flexibility. Their work is exceptional. I highly recommend GEM!

The GEM plumbers were fantastic. They hooked up a new spigot and a back flow preventer for the drip irrigation system I will have installed soon. They explained everything, they were fast and respected my home during the job. I highly recommend GEM for your next plumbing repair or upgrade.
Today Nicole from GEM extended the pipe and added a female adapter for the irrigation system. She was speedy and fantastic!
Jacob from GEM was very nice, fixed problem, and worked around my kids and their toys

How to Know When You Need a New Water Heater Installed

Here’s what to watch for with an aging water heater.

Johnston homeowners should pay attention when these issues appear. GEM can determine whether replacement is your best option.

Water heaters don’t last forever. Once yours reaches 10 to 12 years, components wear out and efficiency drops. Replacing before failure lets you plan the upgrade instead of reacting to an emergency.

Water or dampness around your water heater signals trouble. Even small leaks indicate tank corrosion that will only worsen. Catching this early and scheduling replacement prevents water damage to your home.

If your household used to have plenty of hot water but now runs out quickly, the tank is losing capacity. Sediment buildup and aging components reduce how much hot water your system can deliver. New water heater installation in Johnston restores the supply you need.

An aging water heater works harder to heat the same amount of water, using more energy in the process. If your bills have increased without other explanation, your water heater may be the reason. A new, efficient system brings those costs down.

We Install All Types of Water Heaters in Johnston

Modern water heaters come in several varieties, each designed for specific household needs and priorities.

GEM helps Johnston homeowners navigate these options and install the best system. Here’s what we offer:

Tankless technology heats water on demand rather than storing a heated supply. When you open a faucet, cold water flows through a heating element and emerges hot instantly. This eliminates standby energy loss while providing unlimited hot water. GEM installs tankless water heaters in Johnston for homeowners seeking efficiency and endless supply.

Conventional tank systems maintain a reservoir of heated water ready whenever you need it. These reliable, proven systems offer affordable installation and dependable daily performance. Most Johnston families find tank water heaters meet their needs effectively without unnecessary complexity.

Hybrid units extract warmth from surrounding air to heat water, achieving efficiency far beyond conventional heaters. They keep a tank of hot water available while dramatically reducing energy use. Johnston homeowners focused on long-term savings and rebate eligibility often choose hybrid systems. GEM installs these throughout town.

Water Heater Installation FAQs

Are high-efficiency water heaters worth the extra cost?

For most Johnston 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 Rhode Island Energy rebates, the net cost difference shrinks significantly while the savings continue for the life of the equipment.

Can GEM handle water heater emergencies in Johnston?

Yes. We provide 24/7 emergency service throughout Johnston and the Providence metro 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.

Should I get a gas or electric water heater for my Johnston home?

That often depends on what’s already in your home. If you have natural gas service and existing gas lines to your water heater location, a gas unit typically offers faster recovery times and lower operating costs. If you’re electric-only, an electric water heater or heat pump model avoids the expense of running new gas lines. GEM evaluates your Johnston home’s infrastructure and helps you choose the option that makes practical and financial sense.

What maintenance does a water heater need?

Regular maintenance includes annual flushing to remove sediment, periodic anode rod inspection, and checking the pressure relief valve. These simple tasks extend equipment life and maintain efficiency. Many Johnston homeowners find it easier to have GEM handle maintenance through our Home Comfort Club, which includes scheduled service visits and priority scheduling if problems arise.

What rebates are available for water heater installation in Johnston?

Rhode Island Energy offers rebates on qualifying high-efficiency water heaters, including heat pump models that can significantly reduce energy costs. The rebate amounts vary by equipment type, and eligibility requirements change periodically. GEM stays current on available incentives and helps Johnston homeowners identify which models qualify. We can also assist with the paperwork to make sure you capture available savings.
