Utility Company Rebates

Customers of Southern California Gas Company are entitled to a rebate for both attic and wall insulation which usually amounts to 8-12% of the total cost of insulation. Unlike most contractors Guardian will not only calculate your exact rebate but will submit all necessary paperwork to the gas company on your behalf. All you need to do is sign the application and provide us a copy of your gas bill. Some electric companies, such as Riversite Utility and Colton Electric Utility also offer rebates. SDG&E’s rebate for wall insulation ended in May 2016. Cities not serviced by Southern California Gas, such as Long Beach and Laguna Woods, are not eligible for a utility company rebate.

So Cal Gas Company Rebates have been established and required by the CA Public Utilities Commission to make a certain amount of money available to homeowners of older, under insulated homes.

These rebates are a mandatory condition for So Cal Gas for being allowed to continue their dramatic rate increases.

The amount of the rebate is a function of your square footage and of your existing level of insulation.

Our complimentary assessment allows us to calculate the exact amount of your rebate which we guarantee will be paid by Guardian Insulation in the unlikely event of a denial notice from So Cal Gas.

Federal Tax Credits

Solar customers are entitled to a 30% Federal tax credit. Insulation customers receive 10% of the cost of materials up to a maximum of $500. For this reason we technically “sell” our insulation to customers and provide labor at no charge. For solar customers we offer, as an alternative to a discount, to throw in free insulation, which allows the customer to receive a 30% tax credit on every dollar they spend


Guardian offers low interest financing through HERO (Home Energy Renovation Opportunity) which allows you to deduct the entire cost of your insulation & the full amount of the interest. Depending on your tax bracket this often allows for a net zero interest loan and allows you to pay for your entire project out of the savings on your energy bills. We can also assist you in acquiring a home equity line of credit which offers rates as low as 3.75%.

Additional Incentives

Edison and SDG&E Annual Credits of up to $250 per year on your electric bill are also available for homeowners whose residences are equipped with central air conditioning.
