Mass Save Rebates for High-Efficiency Heating
Upgrading to a high-efficiency gas heating system or boiler is exactly the kind of work Mass Save exists for. We install high-efficiency equipment and handle the rebate paperwork that goes with it. Which programs apply, and who qualifies for them, changes from year to year, so we check what is current when we quote your job. The live program details are on masssave.com.
Comprehensive Gas Heat Services
Gas Piping & Sizing
New and replacement gas piping sized for the appliance load, pressure-tested and permitted — for heating equipment, stoves, dryers, grills, and fire pits.
Appliance Connections
Making the final connection to a furnace, boiler, water heater, or range, with the shutoff, sediment trap, and flex connector the code calls for.
Gas Leak Repair
Repair of the piping once the utility has made the house safe. Leave the house first, then call the gas utility or 911 from outside. Do not use switches, phones or anything that sparks inside the building, and do not go looking for the source. Call us afterwards, once it is safe, for the repair.
Oil-to-Gas Conversions
The piping and appliance side of a conversion, coordinated around the utility’s own timeline for bringing gas to the house.
Meter & Regulator Work
House-side piping from the meter, including re-piping a run that no longer meets the load after an equipment upgrade.
Pressure Testing & Permits
Pressure test on every connection we make, inspection paperwork pulled and closed out, so the work is signed off rather than just finished.
Looking for the equipment rather than the gas line?
This page covers the gas-fitting side. The appliance itself has its own page — that is where the repair, replacement and pricing detail lives.
