Ready for 5-Star Level Service?
Your new furnace runs efficiently from day one. No more waking up to a cold house or watching your energy bills climb every month.
You get consistent heat in every room. The right system, properly sized and installed, means even temperatures throughout your home instead of hot and cold spots.
Your heating worries end. When a gas furnace installer does the job right the first time, you’re not dealing with constant repairs or wondering if your system will make it through another Massachusetts winter.
Dempsey Energy has been installing furnaces for homeowners throughout Plymouth County. We understand how New England winters test heating systems and what it takes to keep homes comfortable.
Our team serves over 12,000 customers in the area through our Dempsey Comfort Club membership program. This isn’t a company that disappears after installation – we build relationships with homeowners for ongoing support.
We focus on residential heating and plumbing services, which means we’re not trying to be everything to everyone. We know furnaces, and we know what works in Massachusetts homes.
First, we assess your home’s heating needs. This means measuring your space, checking your existing ductwork, and determining the right size system for your house. No guessing – proper sizing prevents future problems.
Next comes the installation itself. We remove your old system, install the new furnace, and connect everything properly. This includes gas lines, electrical connections, and ductwork modifications if needed.
Finally, we test everything thoroughly. Your new system gets a complete checkout to ensure it’s running efficiently and safely. You’ll know exactly how to operate your new furnace and what to expect from it.
Ready to get started?
You get proper system sizing based on your home’s actual heating load. Many installation problems start with the wrong size furnace – too small and it can’t keep up, too large and it cycles on and off constantly.
All necessary permits and code compliance are handled. Massachusetts has specific requirements for gas furnace installations, and we know what inspectors look for.
Your installation includes connecting to existing ductwork or modifying it as needed. Sometimes older homes need ductwork adjustments to work properly with modern furnaces. We’ll let you know what’s needed upfront, not after we’ve started the job.
