High Efficiency Furnace and Gas Boiler Program

High Efficiency Natural Gas Furnace, Natural Gas Boiler HES Program

Up to $1,000 rebate!

Reduce your home heating costs with a high-efficiency furnace or natural gas boiler. You’ll enjoy clean, reliable heat and receive an instant discount of up to $1,000 when you install a qualifying natural gas furnace or natural gas boiler.

Achieve efficiencies as high as 97 percent!

In most homes, heating is the single biggest energy expense. Replacing your old furnace, boiler or boiler circulator pump with new high-efficiency heating equipment can take a bite out of your energy costs, plus make your home more comfortable. Older furnace and boiler systems have efficiencies in the range of 56 to 70 percent. High-efficiency heating systems achieve efficiencies as high as 97 percent, converting nearly all the fuel to useful heat for your home. That can mean big savings!

Before you invest in a new furnace or boiler, make your home as energy efficient as possible. Improving insulation and sealing air leaks to stop heat loss may allow you to purchase a smaller, less expensive heating system.
