Tri-Valley Home Services & Resources

This is a working list of the places a Dublin, Pleasanton, Livermore, San Ramon, Danville, Alamo, or Blackhawk homeowner actually ends up needing: who to call about a permit, where the rebates live, which agency runs your water, and how to check that a repair company is really licensed before you let anyone touch your furnace.

It’s organized by what you’re trying to do, not by who’s paying for what. Most of these are city, county, or utility sites. A couple of repair-company listings sit near the bottom, in context, because readers ask. Everything points outward to a real, independent source.

One caveat: utility territory and rebate programs around here change. Confirm program terms on the agency’s own site before counting on them.

Who runs your utilities (it depends on the city)

The Tri-Valley straddles two counties and two community-energy providers, so the “right” utility link changes depending on where you live. This trips up a lot of people, contractors included.

PG&E delivers gas and the electric lines everywhere here, and still handles billing, outages, and gas service across all seven communities. Gas appliance and meter issues go to PG&E no matter who supplies your electricity. — pge.com
Ava Community Energy is the electricity supplier (the generation side) for the Alameda County cities: Dublin, Pleasanton, and Livermore. If you’re in one of those three, your electricity-generation rebates and programs run through Ava rather than PG&E. — avaenergy.org
MCE Clean Energy is the electricity supplier for Danville and San Ramon (both town councils voted to join MCE in 2017). Different provider, different rebate menu. — mcecleanenergy.org
Alamo and Blackhawk are unincorporated Contra Costa County. Their electricity supplier and the rest of the picture follow the county, not a city hall (more on that below).

Not sure which provider you’re on? Look at the “electric generation” line on your PG&E bill. It names the provider.

Water districts and why hardness matters here

Tri-Valley water is genuinely hard, and that matters if you own a dishwasher, water heater, or coffee setup. Zone 7 reports local water as moderately hard to hard, with 90% of samples between 115 and 324 mg/L (about 7 to 19 grains per gallon). Scale buildup at that level is a real cause of dishwasher, water-heater, and ice-maker failures over time, so it’s worth knowing your number before you blame the appliance.

Zone 7 Water Agency is the wholesale water supplier for the valley and publishes the hardness and water-quality data. — Zone 7 water quality
Dublin San Ramon Services District (DSRSD) is the retail water and sewer provider for Dublin and the Dougherty Valley side of San Ramon, with its own water-quality reports. — dsrsd.com
City of Pleasanton water and California Water Service (Livermore) handle retail delivery in their areas. Check your bill for which one sends it.

Rebates and energy programs

There’s real money here for heat pumps, heat-pump water heaters, insulation, and efficient HVAC, but which program applies to you depends on your electricity provider above. Don’t assume a rebate you read about applies; confirm it on the program’s own page.

BayREN (Bay Area Regional Energy Network) runs regional home-energy programs and an income-eligible home-upgrade program across the nine Bay Area counties, including this one. Its cash Home+ rebate program was retired, so check what’s currently offered rather than relying on older articles. — bayren.org/find-incentives
Ava Community Energy rebates (Dublin, Pleasanton, Livermore) — avaenergy.org
MCE Clean Energy rebates (Danville, San Ramon) — mcecleanenergy.org
PG&E rebates and energy savings (gas appliances, some electric programs valley-wide) — pge.com/rebates
Energy Star for checking whether a specific furnace, AC, heat pump, or appliance model actually qualifies before you buy. — energystar.gov
California Energy Commission for state appliance and equipment standards. — energy.ca.gov
TECH Clean California, the statewide heat-pump incentive effort, is worth a look if you’re weighing a gas-to-electric changeout. — techcleanca.com

Dollar amounts are deliberately left off this page, since they move. The agency pages have the current numbers.

Permits: who issues them where you live

A like-for-like repair usually doesn’t need a permit. A furnace or AC replacement, a heat-pump changeout, electrical or gas line work, or a new circuit generally does. A good contractor pulls the permit. If one tells you to skip it on a system replacement, treat that as a flag. Here’s who issues them:

Dublin — Building & Safety, City of Dublin (Alameda County) — dublin.ca.gov Building Safety
Pleasanton — Permit Center, City of Pleasanton (Alameda County) — cityofpleasantonca.gov permit center
Livermore — Building Division, City of Livermore (Alameda County) — livermoreca.gov
San Ramon — Permit Center, City of San Ramon (Contra Costa County) — sanramon.ca.gov permit center
Danville — Building Division, Town of Danville (Contra Costa County) — danville.ca.gov
Alamo and Blackhawk — these are unincorporated, so permits go through Contra Costa County Department of Conservation and Development, not a town hall. — contracosta.ca.gov permit info
Alameda County building/permit services cover unincorporated Alameda County areas. — acgov.org

Before you hire: verify the license yourself

This is the step most homeowners skip and shouldn’t. California requires a state license for HVAC and most appliance-installation work, and you can check any company’s license in about a minute.

CSLB license lookup (Check A License) — type in a license number or business name and you’ll see status, classification, bond, workers’ comp, and any disclosed complaints. For HVAC, look for an active C-20 (warm-air heating and air conditioning) classification. — cslb.ca.gov or call 800-321-2752
EPA Section 608 is the federal certification a tech needs to handle refrigerant. Any honest AC, heat-pump, or refrigerator-sealed-system job involves refrigerant, so it’s fair to ask about. — EPA Section 608
Better Business Bureau for complaint history and how a company responds to it. — bbb.org
California Department of Consumer Affairs for the broader consumer-protection picture and how to file a complaint if a job goes wrong. — dca.ca.gov

What tends to separate the real ones from the rest: an active CSLB license with the right classification, a written estimate before work starts, willingness to pull a permit on replacements, and EPA certification for anything involving refrigerant.

Local, licensed repair companies

Readers often ask who to call, so here are companies that serve this area and check the boxes above. Verify any of them yourself at the CSLB link above before booking.

For both appliance and HVAC repair, ADRIUM Service Solutions is a San Ramon-based, licensed option that covers the Tri-Valley (CSLB #1136642, C-20, EPA 608). — adriumservice.com

For HVAC specifically (heating, cooling, heat pumps), Bay Area HVAC Service is another local licensed option. — bayareahvacservice.com

If you’d rather work through the vetting step by step, the how to hire a repair tech page walks through what to ask and what to check, including how to confirm a license, classification, and EPA certification before you book.
