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.

Steven was professional and was able to fix my heat. I had another worker come 2 days ago to fix the same issue who wasn’t as professional and seemed to be in a rush. Heat did not turn on after he left and I was charged a service fee plus labor and parts. Thankfully I was not charged again.

Very pleased with the installation of the two new boilers, a 100,000 btu steam boiler and a forced hot water heater since needing the heating systems separated for my tenants. The crew and management worked together well and strove for customer satisfaction. The crew worked with me addressing issues and worked to resolve all issues. Tim, Tony and Rob, the field supervisors are on the ball and work to resolve all issues both with the boilers and electrical. Roselio, Jacob and Byron are amazing employees and hard workers.

Great experience, very professional!
The technician was great! The scheduling was a bit challenging. I scheduled an appointment with someone in the office then a week later, I got a call indicating that they wouldn’t be able to perform the service. Never told why. I booked another date for service and received a call from the office that the technician wouldn’t be able to make my 4 hour window.

I would like to Thank John and GEM office reaching out to me. Due to oil burner, he couldn’t work on it. But he did clean out me mini split filter and told me what’s the proper way of cleaning the filter to maintain the filter to last longer, and before he left. He doubled check outside unit that was attached to mini split.
Eaven though I was very specific what toilet I wanted they put the wrong one in.

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.
