Upgrade to Natural Gas Heating

Oil heating, while still effective, is often more expensive to operate and requires more ongoing maintenance than modern gas systems.

If your home still depends on an oil heating system to achieve the warm, consistent temperatures you expect, it may be time to consider a smarter, more efficient solution. Converting to natural gas can deliver steady, reliable comfort while helping you cut down on fuel costs and reduce system upkeep.

At GEM Plumbing & Heating Services, LLC, we handle the entire conversion process from start to finish, making it easy to upgrade your home’s heating system with confidence. Contact us today for oil-to-gas conversion services in Massachusetts and Rhode Island.

What to Expect During an Oil-to-Gas Conversion

At GEM, we follow a tried-and-true process that allows for a smooth transition from oil to gas with minimal disruption to your home and routine. Here’s how we do it:

We start with a detailed evaluation of your current oil system, your home’s layout, and your heating needs. This helps us determine the best path forward for a safe and efficient conversion.

Next, we design a tailored solution, including equipment recommendations, installation scope, and coordination with your local gas utility. You’ll have a clear understanding of the process, timeline, and expectations.

Our licensed technicians handle the full conversion, from removing or decommissioning your oil system to installing your new gas heating equipment and completing all necessary connections.

Once installation is complete, we thoroughly test your new system for performance and safety, then walk you through how everything works so you feel confident and comfortable moving forward.

Had a Kohler kitchen and Bathroom faucet installed with a vanity. Eric and Gem Plumbing did a fantastic job and kept us updated as they went along. Extremely knowledgeable, knew what they were doing, and gave us some information before they left. They explained their warranty and said “we’re around 24/7 if you need us”. I am not a plumber but train others in customer service. And Gem Plumbing gets an A++

As has consistently been the case with Gem, the service man was professional, the work was done right, and everything was clear and above board. But also, as always, it was not cheap. Still, it was an emergency and Gem was the only outfit to actually answer their phone (as opposed to leaving a message or filling out an online form that might be responded to the next day) and schedule an appointment quickly and appropriate to fixing the emergency.

5/5 Stars — Outstanding Service from GEM! I recently had GEM install a new radiator, and I couldn't be happier with the entire experience. From the moment they arrived, the technician , Roselio, was professional, knowledgeable, and extremely respectful of my home. The installation was done efficiently and with incredible attention to detail. They took the time to answer all my questions, made sure everything was running perfectly before they left, and left the work area spotless. It’s rare to find a company that combines such high-level craftsmanship with genuinely friendly customer service. If you need any heating or plumbing work done, I wholeheartedly recommend calling GEM. They truly delivered top-notch results!

Today we had our AC systems installed on the roof of our condo’s. The team from GEM were amazing. They were very professional, communicated every step of what they were doing which gave me great peace. The team, Omar who was the lead, John, Louis, Michael, Mike the electrician were phenomenal. Nick with the crane crew was very nice. I hope I didn’t miss anyone. It was so assuring watching them work so well together. Their respect for each other was present and refreshing. This job was done simultaneously between my neighbors condo and my condo which was huge. The team truly worked AMAZINGLY well together. Their checklist & cleanup was A PLUS PLUS. I would highly recommend GEM and their teams. Anthony Goris was very professional and expertly explained what was happening with my very old AC unit. He was very patient and kind with his time relieving my anxiety of a huge purchase. Edgar Pollino was also very professional and expertly explained my options. He was very knowledgeable explaining everything and very patient & kind answering all my questions. I would highly recommend GEM.

What are the Benefits of Switching from Oil to Gas Heating?

It can be intimidating to move away from what you know works.

Switching from oil to gas, though, can have tremendous benefits for your home. Here are some of the most enticing benefits of switching from oil to gas:

Natural gas is typically more affordable than oil, helping reduce your monthly heating expenses. Over time, those savings can really add up, especially during long New England winters.

Modern gas heating systems are designed to operate more efficiently than older oil systems. That means you get more consistent heat while using less fuel to keep your home comfortable.

Gas systems burn cleaner than oil, which means less buildup, fewer odors, and fewer maintenance concerns. You’ll spend less time worrying about upkeep and more time enjoying reliable heat.

With natural gas, you won’t need to schedule deliveries or monitor tank levels. Your fuel is delivered directly to your home, so you never have to worry about running out when you need heat most.

Installing a natural gas boiler or furnace can save you up to 30% on your energy bills. You might also qualify for rebates. For instance, Rhode Island Energy currently offers rebates of up to $1,000 for a gas boiler or $600 for a gas furnace.

Gas Heating Options in New England

Gas heating is flexible, and finding the right system for your home can make all the difference.

At GEM, we offer a variety of gas heating options to keep your home warm.

Gas furnaces are one of the most common heating solutions, delivering warm air through your home’s ductwork for fast, consistent comfort. They’re a great option if you already have ducts in place and want reliable, efficient heating with quick response times.

Gas boilers heat water and distribute warmth through radiators or baseboards, providing steady, even heat without blowing air. This option is ideal for homeowners who prefer quiet operation and consistent temperatures throughout their home.

Gas-powered or hybrid heat pump systems offer an energy-efficient way to heat and cool your home year-round. They work by transferring heat rather than generating it, making them a smart choice for homeowners looking to maximize efficiency and comfort in all seasons.

Proudly Serving Rhode Island and Massachusetts Homeowners

Choosing the right company is just as important as choosing the right heating system.

You want a team you can trust to do the job right, communicate clearly, and stand behind their work long after installation is complete.

At GEM, we’ve built our reputation on dependable service, quality workmanship, and a commitment to customer satisfaction across New England.

Since 1949, we’ve been helping homeowners stay comfortable in every season. That kind of experience means we’ve seen it all and know how to handle every detail of your conversion.

Our team is fully trained, licensed, and up to date on the latest heating technologies. You can trust that your system is installed safely and correctly the first time.

We handle every step of the oil-to-gas conversion process, so you don’t have to juggle multiple contractors. From planning to final testing, we make the process simple and seamless.

We take the time to explain your options, answer your questions, and keep you informed throughout the project. No surprises, just straightforward guidance you can rely on.

We install trusted, high-performance systems designed for efficiency and long-term reliability. That means better comfort for your home and fewer issues down the road.

Your comfort and satisfaction are always our top priorities. We’re not done until you’re confident in your new system and happy with the results.
