Acosta Heating & Sheet Metal

Acosta Heating & Sheet Metal holds an unblemished 5.0-star rating drawn from 18 client reviews, reflecting consistent excellence in San Francisco's demanding HVAC market. This locally licensed contractor operates from the Bay Area, delivering heating and cooling solutions alongside custom sheet metal fabrication across San Francisco, Marin County, and the Peninsula. The company has maintained continuous operation since 1987, serving residential clients with installations, repairs, and system replacements.

The contractor distinguishes itself through in-house sheet metal capabilities, fabricating galvanized, stainless steel, and copper components for floor heaters, vent flues, and custom ductwork rather than outsourcing these elements. Their service menu covers the full residential spectrum, from gas forced air furnaces and central air conditioning to wall heaters, space heaters, and specialized ventilation for dryers, kitchens, and bathrooms. They maintain same-day or next-day availability across extended weekday hours and weekend service, ensuring residents of foggy neighborhoods and sun-exposed avenues receive prompt attention when systems fail.

Multiple reviewers recount encountering Ron during urgent heating failures. One homeowner described Ron arriving the same day after multiple competitors failed to return calls, completing a furnace replacement at the mother's residence with transparent pricing thousands below competing bids. Another reviewer credited Ron with identifying a carbon monoxide leak during a routine service call, then performing thorough repairs while proactively installing smoke and CO detectors. These scenarios illustrate the technician's commitment to safety verification and follow-through that reviewers repeatedly highlight.
