Mount Olympus HVAC, Electrical & Plumbing

The first variable is the road. Sunset Plaza Drive is a 22-foot easement after parked cars eat into it. Lookout Mountain in Laurel Canyon narrows to 16 feet on the worst curves. Beachwood narrows to one lane at the Hollywoodland gate. None of this matters until equipment arrives, and then it matters more than anything. Our standard practice on hillside addresses is a pre-quote walkthrough with measurements: driveway grade, road width at narrowest curve, overhead clearance to the property entry, and any tree canopy that limits truck height. The numbers go directly into the labor estimate.

Sun exposure on view-home parcels controls the cooling load in ways that flat-lot houses don't experience. A south- or west-facing glass wall above the canyon takes direct solar gain from 11am to 7pm in summer. The slab and interior masonry hold that heat until midnight or later. A 4-ton system that handles the daytime load can fail at 9pm because the building is still releasing absorbed heat into the air. Our approach here is rarely larger equipment. It is variable-speed equipment that can run low-stage continuously in the evening and pull the slab temperature down before the next morning's cycle starts.

Glass-wall homes in the Bird Streets and Trousdale-adjacent ridges respond particularly badly to oversized standard-stage equipment. The system short-cycles, the humidity climbs because the dehumidification cycle never completes, and the owner experiences "clammy comfort" — air that's at setpoint but feels wrong. The fix is modulating compressors (Carrier Infinity 26, Trane XV20i, Daikin Fit) that can ride the load. We have replaced more correctly-sized 2-ton variable-speed systems that work better than the 4-ton single-stage units they replaced than the other way around.

Ductwork in this cluster is often the constraint. Hillside homes built 1950–1975 commonly have ducts routed through 2x4 stud bays or floor joists that were never sized for modern airflow. A 1968 Hollywood Hills modern with 14-inch supply trunks throttling a new 4-ton air handler will measure 1.0+ in. w.c. static pressure when it should be 0.5. Equipment manufacturers' warranties don't cover field installations operating outside spec, and we will not install premium variable-speed equipment on a duct system that throttles it. The duct rebuild becomes part of the scope or we walk away from the bid.

Wildfire smoke is a hills-specific design constraint that didn't exist as a default consideration five years ago. After the 2024 Palisades smoke event we now include Aprilaire MERV-16 cabinets, Lifebreath ERV options, and PurpleAir-integrated automation as standard on premium installs in this cluster. Indoor PM2.5 holds below 20 µg/m³ during smoke events when outdoor levels exceed 175. Most owners who have lived through one event consider this baseline; owners who haven't are increasingly briefing themselves before signing.

Condensate routing on hillside parcels is where small mistakes cause expensive damage. A condensate drain that gravity-feeds across a 30-foot slope into a planter looks fine on paper and floods the foundation in three years. We route condensate to dedicated dry wells, code-pitched lateral runs, or pumped lifts to a verified discharge point — never to a garden bed.

Electrical load on hillside parcels is variable. Older Laurel Canyon and Beachwood houses still run 100-amp service, sometimes 60-amp on the smallest cottages. Newer Bird Streets, Trousdale-edge, and Mount Olympus rebuilds typically run 200-amp or 320-amp. Heat-pump conversion math is completely different on each. We pull the panel inventory before scoping, every time.
