Our Hercules bonus room over the garage never cools down. Would a Cooper&Hunter head fix it?

Very likely. A room over a garage has warm surfaces on several sides, and a central system seldom sends enough air there. A wall head sized for the room's load handles it directly. We check where the outdoor unit can go and how the line set will reach it, then quote in writing.

Can one outdoor unit run heads in two upstairs bedrooms?

Yes, a multi-zone Cooper&Hunter outdoor unit can serve two or more heads, and each room gets its own control. A multi-zone system has more joints and longer lines, so installation quality matters even more, and on a repair we leak-test every connection.

We're in a Hercules townhome with little outdoor space. Where does the outdoor unit go?

Options include a small ground pad, a wall bracket or a spot on a patio, depending on your HOA rules and how far the lines have to run. The unit needs clear air around it and a drain path for defrost water. We look at the site before quoting.

Cooper&Hunter in Hercules

Cooper&Hunter heating and cooling in Hercules.

Hercules is mostly two-story homes, detached and attached: the 1970s and 1980s subdivisions along Refugio Valley Road, plus newer areas like Hercules by the Bay and Victoria by the Bay. Even with central air, an upstairs bedroom or a bonus room over the garage can run warmer than the rest of the house.

A Cooper&Hunter wall head or concealed-duct unit gives that room its own zone. The climate is mild Mediterranean, so the equipment runs at moderate loads, and trouble tends to trace back to installation and upkeep rather than weather. The technician for Hercules is based in Benicia. The $99 diagnostic is credited toward the repair when you go ahead.

Common repairs we handle.

Upstairs head short on charge from a slow leak. An upstairs head on a long line set shows a charge problem first, cooling weakly on the warmest afternoons. We check superheat and subcooling, leak-test the flare joints at both ends, repair the leak, evacuate and weigh in the charge. ADRIUM holds EPA 608 Universal certification for this refrigerant work.
Concealed-duct unit with a clogged filter or drain. Concealed-duct units sit in an attic or soffit, where filters and condensate drains are easy to forget. A blocked filter starves the coil and a clogged drain trips the overflow switch or spills. We clean the filter and coil, flush the drain and confirm the unit shuts off safely if it backs up again.
Remote or wall controller not talking to the head. A dead remote, a lost pairing or a loose wire on a wired controller can look like a failed system. We check the controller and its wiring, reset the head to its defaults, and only then move on to the indoor board.
