Do I need a permit to replace my AC in San Marco?
Yes. Replacing an AC, furnace or heat pump in California requires a mechanical permit - in San Marco that comes from the City of Pittsburg Community Development, Building Division. 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 San Marco?
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 San Marco?
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 San Marco homes is mainly MCE's home energy programs for San Marco customers and BayREN's income-qualified EASE Home program. Programs change often, so we check what's open for your address when we quote.
