Serving Bethel Island
We serve every part of Bethel Island, including Delta Coves, Bethel Island Rd, Gateway Rd and Taylor Rd - it's about 10 miles east via East Cypress Rd and Bethel Island Rd from our Antioch shop. Bethel Island is unincorporated, so we pull permits through Contra Costa County, and we choose equipment that holds up to marina and waterfront exposure on an island reached by a single bridge. Many statewide heat pump rebates are closed for 2026, so when we quote we check what's still open for your address, such as MCE's home energy programs for Bethel Island customers and BayREN's income-qualified EASE Home program.

Questions before you call
Do I need a permit to replace my AC in Bethel Island?
Yes. Replacing an AC, furnace or heat pump in California requires a mechanical permit - in Bethel Island that comes from the Contra Costa County Dept. of Conservation & Development, Building Inspection. Levees are maintained by the Bethel Island Municipal Improvement District. Most replacements also need Title 24 duct leakage testing verified by a third-party HERS rater. We pull the permit and coordinate the inspection.
How much does a new AC cost in Bethel Island?
It depends on the size of the home, the type of system, the efficiency level and the condition of your ductwork. We give you a written quote after looking at the house, with more than one option.
Are there rebates for a new system in Bethel Island?
Some, but fewer than before. TECH Clean California and California's HEEHRA heat pump rebates are fully reserved, and the federal 25C tax credit ended for systems installed after 2025. What's left for Bethel Island homes is mainly MCE's home energy programs for Bethel Island customers and BayREN's income-qualified EASE Home program. Programs change often, so we check what's open for your address when we quote.
