Our professional furnace installation makes sure that your family stays comfortable during cold temperatures.
Your old furnace is costing you money every month it runs. New furnaces use 15-20% less energy than units from even ten years ago, which means real savings on your utility bills.
But the bigger win is reliability. No more middle-of-the-night breakdowns when it’s 15 degrees outside. No more uneven heating where your living room is comfortable but your bedroom feels like an icebox.
A properly installed furnace runs quietly, heats evenly, and gives you one less thing to worry about. You set the thermostat and forget about it, knowing your family stays comfortable no matter what New England weather throws at you.
Dempsey Energy has been keeping Brookline families comfortable through every winter storm and cold snap. We appreciate the distinct challenges of heating older New England homes, from the Victorian houses near Coolidge Corner to the colonial-style homes throughout the area.
Our team handles everything from gas furnace installations to complete heating system upgrades. We’re not the biggest company in Massachusetts, but our 12,000+ customers know they can count on us when their heating system needs attention.
The Dempsey Comfort Club gives our customers priority service and ongoing maintenance to keep their systems running smoothly year after year.
We start with a thorough assessment of your home’s heating needs. This isn’t about selling you the most expensive unit—it’s about finding the right size and efficiency level for your specific space and budget.
Once you approve the proposal, we schedule the installation at your convenience. Most furnace installations take 4-8 hours, depending on your home’s setup. We handle all the details: removing your old unit, installing the new furnace, connecting gas lines, testing all safety systems, and walking you through the new controls.
Before we leave, we run the system through a complete cycle to assure everything operates correctly. You get all warranty information, maintenance recommendations, and our contact information for any questions that come up later.

Your furnace installation includes removal and disposal of your old unit, professional installation of the new furnace, all necessary permits and inspections, and complete system testing. We also upgrade thermostats when needed and can install programmable or smart controls to maximize your energy savings.
Every installation comes with manufacturer warranty coverage plus our guarantee on the installation work. If something isn’t working right, we come back and fix it at no charge.
Many Brookline homes need minor modifications to accommodate newer, more efficient furnaces. We handle ductwork adjustments, gas line updates, and electrical connections as part of the complete installation process.
