Insulation and other home improvements can help you reduce heating and cooling energy waste and lower your monthly energy bills, and weatherization assistance programs in California help make these services affordable for more families and households.

Full home weatherization helps close up air leaks, improve your home’s energy efficiency, and raise your overall home comfort. Greencat offers full home weatherization services throughout California, including Los Angeles, Orange, Western Riverside, and Western San Bernardino Counties.

How Do Weatherization Programs Work?

Some homeowners hear “weatherizing” and think of low-cost home improvements like adding weatherstripping to doors and windows to keep out drafts and replacing light bulbs to reduce energy waste. But whole-home weatherization is much more comprehensive—it involves looking at many different elements in your home, from your insulation and your building envelope to your electrical system, appliances, heating and air conditioning systems, and more, and making improvements that lead to significant savings on your electric bills and utility bills.

Full home weatherization helps you save money in the long run and makes your home more comfortable, but many families can’t afford the upfront costs. Weatherization programs offer financial assistance to low-income households to help. Different programs have different rules about who qualifies for weatherization assistance programs and what weatherizations measures are covered, but many offer reduced costs on services including:

  • Energy audits

  • Insulation upgrades

  • Air sealing to close up holes around windows, pipes, and doors

  • Water-saving low-flow showerheads

  • Repairing and replacing windows and doors

  • Rebates on energy-efficient appliance upgrades

  • Hot water heater and HVAC upgrades

  • And more!

What Home Energy Assistance Programs Are Available for Me?

Weatherization assistance programs are changing all the time, but no matter what programs are currently available, Greencat is here to help. Whether it’s the Los Angeles Department of Water and Power (LADWP) rebates, SoCalGas’s RES DI program, the Department of Energy’s Weatherization Assistance Program (WAP), the Department of Health & Human Services (HHS)’s Low Income Home Energy Assistance Program (LIHEAP), or other efficiency programs, our team of qualified whole-home professionals can work with you to upgrade your California home.

Lower your energy costs and improve your home comfort with full home weatherization from Greencat. Call 323-208-9071 or contact us today to learn more.
