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.

Conducted troubleshooting of Rannai combi boiler. Tech was knowledgeable and thorough. Explained everything.
Tech was prompt, informative and competent—-well done. When making appointment I requested ball park figure for general servicing. Was told a tech would contact me with that information—- that didn’t happen and I was blind-sided relative to service costs.
Walter and Anthony arrived to install my new washlet toilet (bidet) and it was Completed in no time. A great new addition to my guest bathroom with the excellent service that GEM Always provides!
serviced our split system in a competent and efficient manner
Very professional and knowledgeable
Jacob and his partner were great, professional, friendly took the time to show me how to shut the system off if I needed to in an emergency and tagged it for me.
Brain and partner were very Informative and explained what he was going to do , both were friendly
Upon turning on the water in a seasonal property, a dramatic, high-impact plumbing emergency was there to greet me!  I made a few calls – Gem Plumbing was quick to respond, and quite compassionate with their handling my excited concern.   Very shortly after as announced (time of arrival, name of tech. and photo) – Aaron P arrived in his van like one of the super heroes from the Saturday morning cartoons I used to watch.  Yet, I digress.  Aaron was clean, well dressed (for the job) and quite congenial.  Of course, the news that Aaron delivered was unfortunate (for me) and not what I wanted to hear – however – I could tell with Aaron's presence that everything would be ok in the end.  Aaron clearly has great mastery of his skilled profession.  Beyond that- Aaron was courteous, engaging, respectful, and unfazed by the mess he walked into.  So – as I sit here composing this accolade, Aaron is working on the last part of this multifaceted cluster of a plumbing problem.  I must say – the work is pricy – but – for one:  I couldn't do it, and for two:  I KNOW – I am FULLY confident that all of the issues will be resolved by the time Aaron gets back in his van and drives away.

I am NOT amused with my Higher Power's sense of humor today, but I am glad help was just a phone call away.  Thank Aaron – super-hero!

PS – unfortunately ***** I can't give a higher rating than 5 stars.
Just had a plumber out to check my pipes to ensure there were no issues and it was covered under my plan so it Didn’t cost me any out-of-pocket money. Great job as always.
The visit was for an HVAC check per our maintenance contract. Anthony did a great job. He was on time, on point, kind and courteous. He answered my questions and went out of his way to get the job done. Thank you Gem for sending Anthony our way. Thank you Anthony. You are an asset to Gem Plumbing.

Jordan did a great job. My wife called Gem Plumbing & Heating this morning and Jordan was at our home by the end of the day. The office kept us up to date on Jordan’s schedule so we were assured he was on his way.
Great tech. Very professional, efficient and expert in his advice. Just a great representative for Gem. Couldn’t be happier with the service.
When a tree came down on our power lines over Memorial Day, Steve responded and immediately put us at ease during a very difficult time. Our family is currently navigating a significant loss, and dealing with this unexpected situation felt overwhelming. Steve was compassionate, professional, and incredibly respectful throughout the entire process. He took the time to explain what needed to be done, answered our questions, and worked quickly to restore everything safely. His patience, understanding, and genuine care meant more to us than he probably realizes. We are truly thankful for his help and exceptional service. Thank you, Steve, for going above and beyond when we needed it most.
Steve came out on Memorial Day after a tree fell onto our electric lines, and we truly couldn’t have asked for a better person for the job. My family recently suffered an incredible loss and we honestly were not prepared to handle something like this on top of everything else. Steve was not only professional and knowledgeable, but incredibly understanding and patient with us during such a stressful time. He explained everything clearly, worked efficiently, and made us feel like we were in good hands the entire time. People like Steve are rare, and we’re beyond grateful for his kindness and help when we needed it most. Thank you Steve!
Christopher did an excellent job repairing our central air conditioning system. We were his last stop on what I’m sure was a long and busy day in May. He had to get into our attic through a small ceiling hatch in the dark and there was no complaint or negativity. He got the system up and running quickly and had a great attitude.
Christopher Cennamo checked my AC System. He explained things I was unaware of! I was extremely happy with him!!! Thank you Christopher!!!
He was prompt, honest, very thorough and extremely pleasant. I will hire him again in a heartbeat. I just did not get the invoice in my email as promised and the HVAC is not working again after a week -87 degrees in the house again. May need to replace and not repair something.
Technician explains work well and seems very competent. The inability to know, even within hours, his schedule is a substantial problem.
Great job by Nicholas!
Experienced and solution oriented, great work on a complicated set of systems!
Great service !

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.
