Choosing the Right Clean Home Energy Upgrade and Contractor For Your California Home

Home performance covers several services, including:



Insulation helps keep conditioned air from your cooling and heating systems inside your home while preventing outdoor temperatures from infiltrating. Proper insulation in your attic, basement or crawlspaces, and exterior walls reduces energy waste and creates more even indoor temperatures.

Air Sealing

Air sealing

Air sealing closes up small holes and air leaks in your home’s exterior. Those holes and leaks can waste energy, create uncomfortable indoor drafts, and let outdoor air pollutants into your house. It is common for homeowners to complete air sealing and insulation upgrades at the same time.

Energy-efficient window upgrades

Upgrading a home’s windows can save 20-30% in heating and cooling costs for the average California homeowner. Energy-efficient windows reduce heat gain from the powerful summer sun, which is particularly important to a home’s energy efficiency in our state.

Starting Your Home Performance Upgrades the Right Way with an Energy Audit

Usually, a home energy audit is the recommended first step in any home performance upgrade. An experienced and certified auditor will inspect and run a series of building science tests to determine if your home is wasting significant amounts of energy through poor insulation or air leaks.

They’ll also talk with you about issues you might be having with air quality or indoor comfort so that they can recommend services that will make the most significant overall difference to you and your family’s health and comfort.
