AC & Heating Installation in Half Moon Bay
A full AC or heating installation starts with a load calculation, not a guess. We check ductwork condition and electrical capacity against the home's actual square footage and design temperatures before recommending equipment, and we lay out heat pump versus gas-and-AC options with real numbers rather than a single default. The detail that matters in Half Moon Bay is the constant marine layer that limits real cooling days and the salt air that eats outdoor equipment.
Local climate and housing stock both shape an installation here. Half Moon Bay sits directly on the coast, and the marine layer is not an occasional visitor here, it is the default weather. Summer afternoons rarely climb out of the 60s, real cooling days are the exception, and heating is what actually keeps a house comfortable most of the year. Housing runs from the historic downtown core near Main Street to newer subdivisions up Highway 1 and along the ridge above town. Salt-laden coastal air reaches every outdoor unit here and corrodes coil fins, contactors, and cabinets faster than almost anywhere else we work.
In Half Moon Bay, the in-home evaluation for a new installation is free and covers the load calculation, the ductwork and electrical check, and the rebate review. New equipment carries a 10-year manufacturer parts warranty, with labor at 2 years standard and the full 10 years while the equipment stays on our maintenance plan.
What we run into in Half Moon Bay
Load calculation and right-sizing. We run Manual J against the home's actual design temperatures rather than defaulting to a bigger unit, which usually means correctly sized, more efficient equipment.
Heat pump conversions ahead of the 2029 rule. BAAQMD Rule 9-4 starts restricting new gas furnace sales in 2029. On end-of-life systems we lay out the heat pump conversion now so the decision is planned rather than forced.
Install planning built around local conditions. Older coastal homes here often have returns and duct runs sized for a mild climate that never expected much run time. The salt-laden coastal air here corrodes contacts, terminals, and coils noticeably faster than an inland climate would.
Ductless for additions and rooms ducts never reached. A dedicated ductless head sized to that room handles it without re-running ductwork through finished walls.
Permit and inspection coordination. We pull the permit and coordinate the inspection, and we build that lead time into the schedule honestly up front.
