HVAC Efficiency Program

The HVAC Efficiency Program is changing beginning November 1, 2019. Qualifying ENERGY STAR® certified central air conditioners, air source heat pumps, geothermal heat pumps, smart thermostats and ECM furnace motors must be purchased by October 31, 2019 to be eligible for rebates. Purchased equipment must be installed by November 30, 2019, and the rebate application and all required documentation must be received no later than January 31, 2020 from your participating contractor to qualify.


Improve the Efficiency of Your Heating and Cooling Equipment!

Upgrade to high-efficiency HVAC equipment and save for years to come through reduced energy costs. Nearly half of the energy in your home goes to heating and cooling. A properly installed and maintained system can reduce energy use, improve comfort, and help you save money.

Why upgrade to High-Efficiency Equipment?

  • Better Savings: You can save 10 to 30 percent annually on energy bills. A properly designed and installed system allows the equipment to perform at its maximum efficiency, providing you increased energy savings.
  • Increased Comfort: It’s a difference you can feel. With even temperatures, controlled humidity, less noise and dust, you will enjoy the new comforts of home.
  • Better Quality: High-efficiency equipment will last longer, and you’ll be less likely to need costly repairs.


If your heating or cooling system is more than 10 years old, replacing it with a new high-efficiency system can add up to big energy savings.

Seasonal Energy Efficiency Ratio (SEER), is most commonly used to measure the efficiency of a central air conditioner operating over an entire cooling season. The higher the SEER, the more efficient the system.

Energy Efficiency Ratio (EER) is a measure of how efficiently a cooling system will operate when the outdoor temperature is at a specific level (95°F). The higher the EER, the more efficient the system.
