Oakland
Need a HERS (ECC) test in Oakland? We’re already working there.
Replacing a furnace in a Rockridge bungalow, ducting an ADU in Fruitvale, or closing out units in a downtown mixed-use build — Oakland projects all pass through the same gate: independent ECC verification (the test everyone still calls HERS) filed in CHEERS before the City of Oakland finals the permit. We test across the city and the rest of Alameda County on regular routes, which means realistic windows.
