Home Energy Retrofit performed a complete energy audit. They did an extensive safety check of the water heater, furnace and stove to make sure no gasses got where my kids could breathe the exhaust. They pressurized the house with a blower door and did the same with the ducts to see how much they leaked. They made cost-effective recommendations about how I could make the house more comfortable and lower the energy bills.

No carbon footprint and a great investment! A1 Sun, Inc. efficiently installed the perfect solar installation to zero out my PG&E electric bill. Installed in 2005, my system has paid for itself already and I charge my electric car for free! A1 Sun was awesome from the free site survey to expediting the cash rebate.
