New Equipment Installation Across Rhode Island
When a repair stops making sense and it’s time for a new system, Dupuis Energy handles the full job. We install HVAC systems, furnaces and boilers, ductless mini-split systems, and standby generators for homes across Rhode Island and Southern Massachusetts.
Every installation starts with sizing. We calculate the heating and cooling load for your home based on square footage, insulation, window count, and layout. An oversized system wastes fuel. An undersized system can’t keep up. We get it right the first time so your equipment runs efficiently for 15 to 25 years.
As Mitsubishi Electric Elite Diamond Contractors, we carry the highest certification level for Mitsubishi ductless systems and offer 12-year factory warranties on Mitsubishi equipment. Financing is available for all installations.
Our installations are meticulously tailored to meet the distinctive needs of Rhode Island residents. Contact Dupuis Energy to experience top-tier installation services today!
How Can We Help You?
Our Installation Services
We install heating, cooling, and power equipment for homes of all sizes. Here's what each service covers:
HVAC Installation
Full central heating and cooling system replacement, including air conditioning installation for homes upgrading or replacing outdated cooling systems. We remove the old equipment, install the new system, connect ductwork, and test everything before we leave. We work with oil, gas, propane, and electric systems. Most installations are completed in one day.
Furnace & Boiler Installation
Rhode Island is full of homes running 25 and 30-year-old oil boilers and furnaces. When it's time to replace, we handle the full swap: disconnect, removal, new equipment, piping, wiring, and final testing. We install both oil-fired and gas-fired systems.
Ductless Mini-Split Systems
Perfect for homes with no ductwork, finished basements, bonus rooms, or additions that the main system can't reach. Ductless systems heat and cool individual zones with their own thermostat. As Mitsubishi Elite Diamond Contractors, we install, service, and warranty these systems at the highest level.
Generator Installation
Rhode Island gets hit with ice storms, nor'easters, and power outages that last days. A standby generator kicks on automatically when the power goes out and runs on propane or natural gas. We size the generator to your home, pour the pad, run the gas line, and wire it to your electrical panel.
New Equipment Installation FAQ
-
If the repair costs more than half what a new system would cost, or if your system is 15+ years old and breaking down regularly, replacement usually makes more financial sense. Our technicians give you both options with honest pricing so you can decide. If a $300 repair buys you five more years, we'll tell you that.
-
Most residential installations are completed in one day. A straightforward furnace or boiler swap typically takes 4 to 8 hours. A full HVAC system with ductwork modifications can take a full day or occasionally two. We'll give you a timeline during the estimate.
-
Yes. We offer flexible financing options that let you spread the cost over time. Many homeowners finance their installation and pay it off in monthly installments rather than covering the full cost upfront.
-
We install equipment from major manufacturers. As Mitsubishi Electric Elite Diamond Contractors, we specialize in Mitsubishi ductless mini-split systems and can offer 12-year factory warranties on Mitsubishi equipment. For furnaces, boilers, and central systems, we recommend equipment based on your home's needs and budget.
-
In most cases, yes. A modern high-efficiency furnace or boiler can use 15 to 30% less fuel than a system from the 1990s. Ductless mini-splits are even more efficient for targeted heating and cooling. We calculate expected savings as part of every estimate so you know what to expect before you commit.
