HVAC Efficiency Program



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.
