HVAC Installation in Los Gatos

There is no single Los Gatos house. Downtown you have 1880s Victorians and Craftsman bungalows with gravity gas furnaces in the basement, original cast-iron radiators, or wall heaters in each room, and no forced-air ductwork at all. The hills hold mid-century redwood customs and post-2000 luxury builds, usually with full HVAC and multiple zones. Climate zone 4 here also varies by elevation and orientation, with cooling design running anywhere from 88 to 94 degrees depending on where the house sits on the hill.

On hillside homes the sizing problem is the hardest in our whole service area. A 4,000 square foot house with a west-facing master suite up top can have that room calling for cooling at 4 PM while the lower family room is still in morning shade. A single-zone system runs all afternoon trying to satisfy both and never does. For any hillside home over about 2,500 square feet we default to two or three zones with separate equipment per floor, and on the worst west-facing rooms a supplemental ductless head.

On the downtown historic stock, adding central HVAC usually means tearing into plaster to find a path for returns and ducts, which is the wrong answer in a period home. Our standard recommendation there is a multi-head ductless mini-split. One outdoor condenser, one head per primary room, full climate control without the wall and floor destruction, and the original architecture stays intact.

What we run into in Los Gatos

Hillside multi-zone design. On west-facing hillside homes we split cooling into two or three zones with separate equipment per floor. That way the hot upper master gets its own capacity instead of forcing the whole system to chase one room's afternoon load.

Multi-head ductless for Victorians and Craftsmans. Downtown homes with no ductwork get one outdoor condenser and a head per primary room. No plaster surgery, no hunting for return paths, and the period architecture stays untouched. We size each head to its room rather than the house total.

Hybrid central-plus-ductless setups. When a hillside home has good central ducts but a couple of impossible rooms, we keep the central system and add ductless heads only where the load demands it. That is usually cheaper than upsizing everything.

Load calculation per zone. We run Manual J per zone, not per house, on these varied homes. Orientation and elevation move the load room to room here more than almost anywhere else we work, and the numbers go on the estimate.

Permit coordination on historic and hillside lots. We pull permits and coordinate inspection, and on historic-core properties we account for any added review. We tell you the realistic lead time before the install date is set.

HVAC Installation in Los Gatos: common questions

You are in San Ramon. Will you really come out to Los Gatos for an install?

Yes. We cover the full Bay Area and do a good amount of Los Gatos hillside and downtown work. Installs are scheduled rather than same-day, so we book a site visit for the load calculation and estimate first, then set the install date. Call (925) 999-4095.

My downtown house has radiators and no ducts. Can I get central air?

You can get full cooling and modern heating, but running new ductwork through an 1880s home usually means tearing into plaster and still ending up with compromises. In nearly every case we recommend a multi-head ductless system instead: one condenser, one head per room, no structural surgery.

Why does one room in my hillside house never get cool?

Almost always a west-facing room on an upper floor with afternoon sun and a single-zone system trying to cover the whole house at once. The fix is zoning: separate capacity for that part of the house, sometimes a dedicated ductless head. We confirm it with a per-zone load calculation.
