There has never been a better time to upgrade your home and make it more energy efficient. With cash incentives from BayREN, upgrading your home to improve the overall air quality and reduce your energy use is a cost-efficient way to add upgrades to your single family home.

Upgrading to an energy efficient home isn’t just about increasing your home’s value. Making these upgrades can contribute to your overall health through improved indoor air quality. In addition, home energy upgrades reduce your energy bill and improve the sustainability to your home. Taking advantage of BayREN’s cash incentive program offers many long-lasting benefits to you and your family. Home Upgrade combines multiple improvements to increase your home’s overall energy efficiency, saving you energy and money. Eligible home improvements include:

  • Air sealing
  • Duct replacement/sealing
  • Insulation to your attic, wall, floors, and/or ducts
  • High-efficiency installations of:
    • Furnace
    • Air-conditioner
    • Water heaters
    • Windows

The More Upgrades You Make, The Greater The Incentives (up to $3150!)

The way it works is simple: the more upgrades you make to your home, the more cash incentives you are eligible for.

All upgrade measures are worth a pre-determined number of points that count toward your Home Upgrade incentive. You must choose at least three measures. The more points you earn by combining upgrades, the higher the incentives you can receive.

Incentives are awarded at $10 per point up to a maximum of $3,000. An additional $150 incentive is also included to offset the cost of the required combustion safety testing on completed projects. There is a minimum of 150 points for a $1,500 rebate.
