Eric Governor from GEM came to my house today. I was very overwhelmed with the electrical issues I was having and he took his time explaining everything to me and what my options were. He didn’t leave until I understood what was needed. They were very nice and made me feel comfortable.
Help with well for irrigation system.
Cory was great. Fixed my problem in no time.
Was able to receive last minute, same day service from Abe and Logan. They were prompt, courteous and saved us a boat load of money. They found our tub leak easily and took care of it immediately allowing us to choose the repair option that was in our budget. Thanks very much!
Every person I dealt with at GEM was very professional and very pleasant. No long wait for the house call or the installation.They installed my three mini-splits and condenser in under 7 hours and cleaned up after themselves. The entire team of four men knew exactly what they needed to do. I would highly recommend them.
Excellent Service
I had my A/C go down on a 90° Friday. GEM sent David Salvatore to my house same day, and he was back first thing Monday morning with the parts to repair. He was an honest gentleman and a clean worker. He even found me a first time customer coupon to save me a few dollars. Are they priced a bit higher than some other companies? Yes, they are. But my existing company, Mutual Engineering, wasn’t even going to come for a diagnosis for a week! This is a perfect example of you get what you pay for. In addition to this condenser repair, David showed me maintenance that I should have been doing on a separate mini-split system installed by my now previous company. Mutual Engineering never informed me of this requirement. Bottom line is when it’s extreme heat or cold and your HVAC goes down, you want service quickly. I got that, and it was worth every penny.
Outstanding service Brian … Thank you so much for fixing my electrical problems with such accuracy and professionalism!!
Great professionals
Bill & Anthony did a thorough job on my HVAC system maintenance call. Pleasant, friendly, & knowledgeable. Thank you both!
We discovered a leak under our kitchen sink and as luck would have it, we had company coming to our house the following day. A neighbor gave me the name and phone number to GEM Plumbing. They came to our rescue and their guys were here the following morning, right at the promised time. We were very happy with their two guys and all was fixed within a few hours. Thank you so much!!!!!!
Service was outstanding done in a timely fashion clean neat and professional a little expensive
Steven was great to work with and explained the issue we were having very well.
Edward was great. My mother was having a drainage issue. Other companies have come in and charged her money and not fixed the problem. Edward got down to the root of the problem and fixed it for us. Response time is quick. I booked the appt on Tuesday evening they were there Wednesday morning. In the past my husband and I have used GEM for an emergency where we called at 7am and they were there by 9 same day. Obviously those things cost money, but it is very reasonable for what you are getting. I would absolutely recommend GEM to family and friends.
Excellent service, soup to nuts 24/7!
Service tech was exceptional Joe Oxford
Very quick service! Answered the call had someone come same day for a quote next day they were able to install! Impeccable service
I had a water leak in the AC unit and while they were here also found out that the capacitor was old and needed to be changed to get to right cooling temperature.
A little pricy , l paid $750 for a new capacitor and removal of some debris in the water collector in Ac unit.

But it still great , since they showed up as same day appointment and fixed everything.
Nicholas was very professional and did the job quickly.
The service was great!! The technicians were very nice, professional and polite. They explained everything and did their best to help us. Thank you!
The technician John Pete was
Very thorough and professional. He identified a problem unrelated to the service call and took care of it.
Nick is really excellent at explaining the issue with my system
and articulated solutions perfectly. Excellent work!


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.
