Dempsey Energy has been keeping Plymouth County families warm for years. We’ve built relationships with over 12,000 local customers who trust us for reliable heating solutions.
What sets us apart is our focus on getting it right the first time. We don’t rush installations or cut corners on the details that matter. Our team understands Onset’s unique heating challenges, from coastal humidity to the older home construction common in this area.
Our Dempsey Comfort Club gives you ongoing support and priority service, because we know furnace installation is just the beginning of a long-term relationship.
First, we’ll assess your home’s heating needs and existing ductwork. This isn’t a quick sales pitch – it’s a thorough evaluation to make sure you get the right size system for your space.
Next comes the installation itself. We’ll handle all permits, remove your old system safely, and install your new furnace with proper connections to gas lines, electrical, and ductwork. Everything gets tested before we leave.
After installation, we’ll walk you through your new system’s operation and maintenance schedule. You’ll know exactly how everything works and what to expect. We’ll also schedule your first maintenance visit to keep your warranty valid and your system running efficiently.

Your installation includes proper system sizing, permit handling, and complete removal of your old equipment. We’ll modify ductwork as needed and ensure all connections meet local building codes.
