Heating & Air Conditioning in Sunol, CA

What makes Sunol different for heating and cooling work?

Sunol is not a city. The Sunol Citizens’ Advisory Council site describes it as a rural, unincorporated community with fewer than 1,000 residents spread over 86 square miles, and Alameda County provides its local government services. That shapes a few things about your project:

• Permits go to the county. There is no Sunol building department.
• Electricity comes through Ava Community Energy, the county’s community power provider, with PG&E delivering it.
• Homes are spread out. Sunol sits inland in the hills between Fremont and Pleasanton, and summers away from the bay can run warmer, so a well-maintained AC or heat pump matters.

Which services do Sunol homeowners use most?

Pick the area that fits your home:

• Cooling: AC repair when the system runs but won’t cool, and an AC tune-up for $135 before summer.
• Heating: furnace service and heat pumps that cover heating and cooling with one outdoor unit.
• Water heaters: replacements and heat pump water heaters.
• Indoor air quality: duct cleaning and dryer vent cleaning.

For yearly upkeep, the Comfort Club Single System plan is $9.95/month or $115/year for one visit a year, and the Full plan is $18.95/month or $225/year for two visits.

What do Sunol homeowners ask us?

Where do I get a permit for a new AC or water heater in Sunol?

From Alameda County. The county’s building permit page serves its unincorporated areas and names Sunol among them. The Public Works Agency’s permits page sends applicants to the Alameda County Permit Portal to apply, submit plans, schedule inspections and check status. The agency’s office is at 399 Elmhurst Street in Hayward. We file the application as your contractor and set up HERS testing when the new system needs it (an independent test California’s energy code calls for on many installs).

Is Sunol covered by Ava Community Energy?

Yes. Ava’s Alameda County page lists Sunol by name among the unincorporated communities it serves. Ava’s jurisdiction table shows Bright Choice as the default plan for unincorporated Alameda County homes as of November 2026. Ava was formerly East Bay Community Energy.

Are there rebates for a heat pump in Sunol?

Check Ava’s Savings & Incentives page, which has a finder for rebates, tax credits and discounts. Because programs and eligibility shift, we leave amounts off this page. For a heat pump or heat pump water heater, you may qualify; call us and we’ll check what applies to your home.

Have you worked near Sunol?

Our nearest posted projects are in Fremont, just over the hills: a furnace replacement and a mini-split service call. One tip for rural lots: keep about 2 feet clear around the outdoor unit, free of brush, leaves and stored items.
