What is a Home Energy Assessment

 A home energy audit, also known as a home energy assessment, is the first step to assess how much energy your home consumes and to evaluate what measures you can take to make your home more energy efficient. An assessment will show you problems that may, when corrected, save you significant amounts of money over time.

The whole-home energy assessment will help you understand and decide which improvements would be most beneficial for your home and help determine the amount of cash-back incentives you can receive from your utility rebate program.

You could save 5%–30% on your energy bills by making efficiency improvements as identified in your home energy assessment.

The Residential Energy Efficiency Loan (REEL) program was designed to help California homeowners and renters access affordable financing for energy efficiency projects.

Owners of any residential property are eligible for the REEL program, as are renters at the discretion of the lender and with the property owner’s permission. Customers may upgrade a single-family home, townhome, condo, duplex, triplex, fourplex or manufactured home. And, with REEL, renovations for up to four units can be bundled into the same loan.

Eligibility requires that the property receive electric or natural gas service from Pacific Gas and Electric Company (PG&E®), San Diego Gas & Electric Company (SDG&E®), Southern California Edison (SCE®) or Southern California Gas Company (SoCalGas®). For complete program rules and regulatory information, please reference the REEL Program Regulations+.

Reduce before you produce! The REEL program prioritizes energy reduction (through energy efficiency) over energy production. At this time, lenders are not offering solar loans through the REEL program.

With different lenders and loan options, there’s a REEL solution for your home improvement needs.
