Oil to Gas Conversion Services in Worcester, Middlesex & Norfolk Counties

Heating your home with oil can feel like a constant hassle. Rising fuel costs, messy deliveries, and frequent maintenance make it hard to keep your system running smoothly. Older oil burners are often less efficient and produce more emissions, which can leave you spending more on fuel while getting less comfort in return.

At Landry Mechanical Inc Plumbing HVAC & Electric, we make it simple to switch to a cleaner, more efficient heating solution. Our oil to gas conversion services, in Millbury and across central and eastern Massachusetts provide a safe, cost-effective way to modernize your system. With expert planning, professional installation, and complete oil tank removal, we handle the entire process so you can enjoy reliable warmth and lasting savings. Contact us today to schedule your gas conversion service.

Understanding Oil to Gas Conversion and When It’s the Right Choice

An oil to gas conversion replaces your existing oil-fueled heating system with a natural gas system designed for cleaner, more efficient performance. The process typically involves removing the oil tank, installing new gas lines, and upgrading your boiler or furnace to run on natural gas. Once completed, you’ll notice quieter operation, more consistent heat, and a significant reduction in maintenance needs.

For many homeowners, the decision to convert comes down to cost, convenience, and sustainability. If you’re tired of scheduling oil deliveries, dealing with fuel odors, or facing rising oil prices, a gas conversion can make heating your home simpler and more affordable. Converting also adds long-term value to your property and helps lower your carbon footprint, making it a smart investment for the future.

Gas Conversion Services We Offer

Switching your home from oil to gas is a major step toward cleaner, more efficient heating. Landry Mechanical provides complete conversion services that take care of every detail so you can transition confidently and safely.

Comprehensive System Evaluation

We start with a full inspection of your existing oil heating system to determine the best conversion plan. Our team reviews your home’s heating requirements, fuel line access, and available gas service in your area. We’ll walk you through the entire process, explaining what’s needed for a smooth and cost-effective switch.

Safe Gas Line Installation

A safe, properly sized gas line is essential for dependable heating. Our licensed technicians install new gas piping, pressure regulators, and shut-off valves while following all local codes and manufacturer specifications. We coordinate with your utility company to ensure a seamless connection and secure, long-term performance.

Equipment Upgrade and Conversion Setup

Once the gas line is in place, we replace your oil burner with a compatible gas system or install a brand-new, high-efficiency furnace or boiler. Every installation includes proper venting, burner calibration, and full system testing to ensure clean, efficient operation from the first day of use.

Oil Tank Removal and Site Cleanup

When converting from oil, the old storage tank must be safely removed. We handle this step completely, draining and cleaning the tank before hauling it away. Our team follows Massachusetts environmental regulations to protect your property and the surrounding area.

Final Inspection and Performance Testing

Before we call the job complete, we perform detailed safety checks and combustion testing to confirm your new gas system is running at peak efficiency. We’ll also walk you through maintenance basics and provide clear documentation of your new setup so you can feel confident in your investment.

Ivan came to my house to do my fall maintenance service. You can't ask for a better person! He explained everything he was doing as he did it. Felt more at ease with him testing the part of the systems he was checking, knowing the values that the systems need to run at, and making sure they are working.

I will be asking for him from now on to service my system.

What did I pay? I pay $20 a month for a service contract and get 2 maintenance checkups, per year, free. Also an emergency call is a flat fee of $299 or $399 each call (Can't remember which one it was). If you have the contract, you pay $99 for the call, plus whatever work and parts they need.

Great company as long as they have people like Ivan. I only gave him 5 stars because i was prevented from giving him 10 stars.

Aaron from Landry was friendly and informative, and much less pressure than Heritage. He gave a second opinion on my furnace at no cost.

Working with Landry was very easy. I most appreciate that they send a picture of the technicians, along with a background check clearance before anyone comes to the house. Friendly, professional, and thorough. Cost is given up front with no surprises.

I had a leaking connection on my water heater. The technician came and assessed and gave me options to repair or replace but said I could probably get a few more years out of the tank. He provided 3 quotes. Repair only. Replace with new tank. Replace with a tankless water heater. No push to go with. Full replacement which I appreciated. Friendly, professional, respect for my property. All things I look for.

I had a fantastic experience with Sam and Nick from Landry. Both were highly professional electricians who went above and beyond.

They took the time to clearly explain the safety benefits of arc fault breakers, which was incredibly helpful. Their expertise was proven almost immediately when one of the new breakers tripped, signaling a real issue in my home's wiring. Sam and Nick quickly troubleshot the problem, identified some poor workmanship from a previous contractor, and fixed it on the spot. Once repaired, the breaker worked perfectly.

They also moved an outlet over to another wall for me and did a beautiful, seamless job. I highly recommend Landry Mechanical, and specifically Sam and Nick, for any electrical needs in the Worcester area!

We came home from vacation to find that our hot water heater had died and was leaking all over our utility room. I called up Landry, and they had a technician come out within about an hour, and we had a new hot water heater a few hours later! They were extremely professional and thorough, and left our house clean. We will definitely use them again!

Landry have done absolutely outstanding work again. I've written prior positive reviews, so I won't go into detail here. Landry replaced two large pressure tanks in our water treatment system. In summary: Extremely pleasant trustworthy reliable workers. This time they threw in replacement of a leaking water intake pipe - copper with brass fittings - for free.

Landry Mechanical just wrapped up the installation of a heat pump at my home. Normally, I’m not a testimonial giver, but I was so pleased with the team who came and the service I received that I felt compelled to do it this time. Wonderful transparency throughout the entire process – – from assistance with paperwork through scheduling, and then through the installation itself…. And then, before they left, ensuring I was comfortable with the equipment, including how to use the new thermostat.

The entire time the crew was on site, they were incredibly focused on delivering a quality product along with a quality installation, and took great care to ensure they kept our home clean of debris, both inside and out.

I’m not planning on a second heat pump for the other zone in my house, but if the need does arise, I know I will be calling Landry Mechanical again.

I had technicians Nick and Ricky at my house today to install hot water heater. These gentlemen are first class, extremely courteous, very nice to work with. And in my 130 year old house they were thrown curveball after curveball and knocked it out of the park every time. These guys did a great job.I recommend Landry Mechanical any day of the week.

Landry helped to resolve a problem with my boiler quickly. The initial evaluation showed the new boiler was working fine but lacked the electrical connected needed to fire up. Thankfully, Landry offers electrical services too so another tech was able to quickly wire a new connection and get us fired up in time for the cold. Thanks for the great service! Both technicians were friendly and knowledgeable
