The company behind the name
Oren's HVAC Services does one thing: keep East Bay homes and businesses comfortable. Through hot inland Tri-Valley and Concord summers, damp bayside winters, and wildfire-smoke season in the hills, our technicians repair, replace, and maintain heating and cooling systems across both counties — from first-time AC in older Oakland and Berkeley homes to multi-zone systems in newer construction.
We’ve stayed deliberately focused. No franchising, no call-center layers between you and the people doing the work — just a licensed local contractor whose word means what it says.
We’re based in Oakland at 10127 Dante Ave, Oakland, CA 94603, and our service area covers all of Alameda County and Contra Costa County.
