Gas Conversion Process Green Harbor

How We Handle Your Conversion

First, we check if natural gas is available on your street. Most Green Harbor neighborhoods already have gas lines, so connection is usually straightforward. If you need a new gas line from the street, we coordinate with the utility company to get it installed.

Next, we remove your old oil tank and heating equipment safely and properly. We handle all the disposal requirements and permits so you don’t have to worry about it.

Then we install your new high-efficiency gas furnace or boiler. We connect it to the gas line, test everything thoroughly, and make sure your new system is running perfectly before we leave. The whole process typically takes 1-2 days, and we often complete conversions during off-seasons to avoid any heating interruptions.

Your oil to gas conversion includes complete removal of your old oil tank and heating system, installation of new high-efficiency gas equipment, and connection to the natural gas line. We handle all permits, inspections, and coordination with the gas company.

Green Harbor’s coastal location means your heating system works overtime during nor’easters and winter storms. That’s why we only install high-efficiency gas systems that can handle whatever New England weather throws at them. These systems reach up to 97% efficiency, compared to older oil systems that might only reach 80%.

We also help you take advantage of Mass Save rebates and 0% financing options that can significantly reduce your upfront costs. Many Green Harbor homeowners qualify for rebates up to $1,000 on high-efficiency gas equipment, plus financing that makes the conversion affordable right away.
