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.

Evan from Landry Mechanical came last week to do our yearly heating plant review. He explained what he was doing as he proceeded, and completed review and, happy to say, everything was fine.

Update Aug 22, 2026:

We had three separate services completed yesterday and, as we've now come to expect from Landry, every technician was professional, knowledgeable, and courteous. Eddy Russell handled our HVAC maintenance and did a thorough job, explaining what he was doing along the way, adjusting his work order a bit, and completing the job in a timely fashion. Jose Viveiros took care of our plumbing service efficiently, fixed two issues he discovered (Kitchen sink & Bathroom shower), and left everything clean and in great shape. Jonathan Torres installed two mini-split dongles and he and his teammate were prompt, detail-oriented, and made sure everything was working properly before they left. Great communication, quality work, and a smooth experience overall. The only issue I have with to report is not related to the work that was done, but rather the fact that it took many many months for the dongles to be installed. I would have expected some kind of consideration for the prolonged delay. Having said that, I do highly recommend Landry Mechanical.

We engaged with Landry Mechanical and several other HVAC providers in November ‘22 to get bids to replace our aging AC system. The decision to go with Landry was beyond easy, it was a classic no brainer. Between their obvious depth of comprehensive HVAC experience, their knowledge of how to integrate the MASSSAVE incentives into the project, and their commitment to minimizing environmental impact I readily made the decision to leave my long time HVAC provider.

Because of their high value consultative sales approach (Ryan) we ended up contracting with them to replace not just the AC but to install a hybrid ((ductless (mini-split) and duct (heat pump)) system that was completed today under the direction of Jason and with the help of MANY of their team as they worked miracles to complete the install around our hectic holiday schedule. And to top it off, they have guided us through the MASSSAVE process every step of the way so that our actual out of pocket expenses are in part subsidized and part financed at 0%.

In short, without question they have exceeded all my unreasonable expectations from the point of initial engagement to the installation itself. Great team, great customer sensitivity, and now we are fully expecting great reduction in our environmental imprint.

My tankless hot water heat exchanger corroded and failed, called Landry for repair, Landry sent the technician on the same day. Technicians came on time and looked into the issue and worked with manufacturer to get the part overnight shipped under warranty, came next day and replaced the part. Great service.

It starts with the professionalism and courtesy from Anthony and Nick. Not only did they do a great job, but they clean any mess they make. (I know that sounds simple, but you’d be surprised how many contractors miss this point) They kept the noise down to a bare minimum out of respect for my neighbors. They also were working to complete the job from the minute. They came in till the minute they left. Very impressive

I will certainly use them again.

Drew was excellent. He was timely, polite and very knowledgeable. He identified our problem which was atypical with his thorough examination. Even gave us a plan B if the issue should happen again. We greatly appreciated his expertise as well as his teaching. We will definitely be keeping Landry as our provider of choice for HVAC service and products.
