Not just new equipment — a system done correctly.
Packaged Unit Installation
ABC Service installs gas/electric, heat pump, and dual-fuel packaged systems for residential and light commercial properties. Selection is matched to building load, duct capacity, and the operating profile of the space.
Single-cabinet equipment simplifies refrigerant work and roof penetrations but punishes any compromise in sizing or curb fit. We measure existing curbs, verify adapter requirements, and pre-build transitions before the crane lift is ever scheduled.
Rooftop Replacement
We coordinate with roofing and structural trades for clean curb adaptation, crane lifts, and condensate routing. Done correctly, a rooftop or pad-mounted package unit is a 15+ year asset.
Roof loading, condensate drainage, and weather-tight flashing are coordinated with roofing and structural trades before the unit lands. The handoff between crafts is where most premature failures begin — we manage it as one continuous scope.
Repair & Diagnostics
Bay Area mornings recover significant free cooling through a properly set up economizer — and most performance complaints trace to dampers, sensors, or control logic that drifted out of spec. We service refrigerant, gas, electrical, economizer, and control-board faults across all major packaged platforms.
Economizer dampers, sensors, and control logic ship from the factory in a generic configuration that rarely matches the building. Field setup, low-ambient lockouts, and minimum outdoor-air settings are tuned to the actual operating profile and documented in the controls.
Commercial Maintenance
For restaurants, retail, and light commercial sites, uptime is the product. We offer quarterly and biannual maintenance plans that prevent the calls nobody wants on a Friday afternoon.
Our commercial maintenance plans cover filter, belt, refrigerant, combustion, electrical, and control checks on a documented schedule with photo records. For tenants whose business depends on uptime, that documentation is as valuable as the service itself.

Why this is worth doing right.
Small footprint
Packaged units keep equipment off the building floor — useful when interior mechanical space is at a premium.
Serviceability
Single-cabinet design simplifies long-term maintenance and refrigerant work.
Commercial uptime
For commercial spaces, the right unit and the right install translate directly to operating reliability.
Efficiency
Modern packaged units with proper economizer setup recover significant energy on cool Bay Area mornings.
