HVAC Efficiency Program

Improve the Efficiency of Your Heating and Cooling Equipment

Is your heating or cooling system noisy? Do you notice excess dust collecting in your home? These may be signs that it is time to replace your HVAC system. Upgrading to high-efficiency HVAC equipment can help you save up to 20% annually on energy costs.

Other signs it may be time to replace your HVAC system: 

  • Your equipment needs frequent repairs, and your energy bills are going up.
  • Some rooms in your home are too hot or too cold.
  • Your equipment is more than 10 years old.

Not sure how old your unit is or if it is time to replace it? Contact your contractor or click here to learn more.

Why Choose High-Efficiency Equipment?

  • Better Savings: 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.
  • 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.
