Professional furnace installation that works when you need it most, backed by local expertise you can trust.
You shouldn’t have to worry about your furnace failing when temperatures drop. A properly installed gas furnace gives you consistent, efficient heat throughout your Rockland home, even during the coldest Massachusetts winters.
When your new furnace is installed correctly, you’ll notice the difference immediately. Even temperatures in every room. Lower energy bills each month. The confidence that comes from knowing your heating system won’t leave you in the cold.
That’s what happens when experienced furnace installers handle your installation from start to finish. No shortcuts, no guesswork, just reliable heating performance you can count on for years to come.
Dempsey Energy has been keeping Plymouth County homes comfortable through every type of Massachusetts weather. We understand how older New England homes heat differently and what it takes to install furnaces that perform reliably year after year.
Our approach is straightforward: we show up when we say we will, install your furnace right the first time, and make sure you understand how everything works. Over 12,000 local customers trust us with their heating and cooling needs.
We’re not the biggest company in the area, but we’re built around taking care of our neighbors in Rockland and surrounding communities. That’s why we created the Dempsey Comfort Club to make sure your new furnace keeps running smoothly long after installation day.
First, we’ll assess your home’s heating needs and existing ductwork to determine the right furnace size and type. This isn’t guesswork – proper sizing is critical for efficiency and comfort. We’ll also check your electrical and gas connections to ensure everything meets current Massachusetts building codes.
Next comes the actual installation. We’ll remove your old furnace safely, install the new unit, and connect all gas lines, electrical connections, and ductwork. Every connection gets tested for safety and proper operation before we consider the job complete.
Finally, we’ll walk you through your new system’s operation and maintenance requirements. You’ll know how to change filters, what sounds are normal, and when to call us. We’ll also discuss Dempsey Comfort Club membership to keep your furnace running efficiently for years to come.

Every furnace installation includes proper sizing calculations, safety inspections of gas lines and electrical connections, and testing to ensure your system operates at peak efficiency. We handle all necessary permits and ensure your installation meets Massachusetts building codes.
Your installation also includes a complete walkthrough of your new system’s operation, maintenance requirements, and warranty information. We don’t just install and leave – we make sure you’re comfortable operating your new furnace and know who to call if you have questions.
Many Rockland homeowners are surprised by how much more evenly their homes heat after a professional installation. That’s because we take time to properly connect and seal all ductwork connections, not just hook up the furnace itself. The details matter when it comes to home comfort and energy efficiency.
