We moved up to the Hayward Hills. Why does our AC run so much more than it did in the flats?

The hills sit above the marine air more often and run several degrees warmer, so the same system works harder. If it struggles to hold temperature, we check the charge, the coil and the airflow and show you what we find.

Our Tennyson house has a wall furnace and no ducts. What cooling fits?

A ductless heat pump, sized for the rooms you use. It heats as well, so it can replace the wall furnace when that finally quits. We look at the panel and a spot for the outdoor unit and quote it in writing.

Can a leak on our 94542 system be repaired rather than recharged every year?

Yes. We pressurize the system with nitrogen, find the leak with an electronic detector and repair it, then pull a vacuum and weigh in the charge. That work is done under ADRIUM's EPA 608 Universal certification.

AC Repair in Hayward

AC Repair in Hayward.

Hayward is two climates under one name. The flats through Mt Eden, Tennyson, Fairway Park and the Southland area sit in the path of marine air coming through the gap, and most summer afternoons stay in the 70s. The 1950s and 60s tracts there have furnaces in hall closets and garages, and some older blocks still run original wall furnaces, so cooling is light work in 94541, 94544 and 94545.

The Hayward Hills above the CSU East Bay campus climb out of the fog more often and run several degrees warmer. Homes in 94542 went up from the 1980s through the 2000s with central AC and bigger two-story loads, and those systems are old enough now for capacitors, contactors and coils to fail. We diagnose for $99, credited toward the repair, and quote in writing before any work.

Common repairs we handle.

Two-story hills home hot upstairs. A single system on a two-story house can leave the top floor warm even when the equipment runs fine. We check the airflow split between floors, the return path and the charge before suggesting any bigger change.
Pitted contactor on a 1990s hills condenser. A contactor with burned points can chatter or fail to pull in, so the outdoor unit never starts. We check the coil voltage and the contacts, replace it, and confirm the compressor and fan amps afterward.
Iced coil on a hall-closet furnace with add-on AC. A closet furnace with a cooling coil on top can freeze the coil when the filter is choked or the return is too small. We thaw it and measure airflow before we look at the charge.
A 1990s hills system losing its R-22 charge. Older R-22 equipment that loses charge is expensive to refill, because that refrigerant is no longer produced. We find and price the leak repair and set it beside a replacement quote so you can choose.
