Commercial Split & Package
Repair, Service & Replacement
Split systems and packaged units serve offices, retail spaces, restaurants, and medical facilities throughout the Bay Area. When the condenser fails outside and the building heats up inside, tenants and customers notice immediately. We repair, maintain, and replace commercial split systems, packaged heat pumps, and dual-fuel units from every manufacturer.
Split & Package System Services
Complete repair, maintenance, and replacement for commercial split and packaged HVAC systems.
Compressor & Refrigerant Repair
Compressor replacement, refrigerant leak detection and repair, TXV and metering device service, and proper charge verification. We handle R-410A, R-22 systems, and all commercial refrigerants under EPA 608 compliance.
Condenser & Evaporator Coil Service
Coil cleaning, leak repair, and replacement. Dirty condenser coils on ground-level units collect debris, reduce efficiency, and shorten compressor life. Evaporator coil leaks cause gradual refrigerant loss and declining performance.
Blower Motor & Air Handler
Blower motor replacement, ECM motor diagnostics, belt drive service, bearing lubrication, and airflow verification. A weak blower motor means poor air distribution, hot and cold spots, and tenant complaints.
Heat Pump & Dual-Fuel Service
Heat pump reversing valve repair, defrost board service, auxiliary heat troubleshooting, and dual-fuel system optimization. Heat pumps are increasingly common in the Bay Area as businesses shift toward electrification.
Thermostat & Controls
Thermostat replacement and programming, control wiring diagnostics, zone damper service, and smart thermostat integration. Proper controls setup prevents short-cycling, reduces energy waste, and improves occupant comfort.
System Replacement
Complete system changeouts including condenser pad or wall bracket, line set, air handler or furnace, thermostat, and ductwork modifications. We size systems properly using Manual J calculations — oversized systems waste energy and create humidity problems.
Commercial Split & Package Systems: What to Know
Commercial split systems and packaged units are the most common HVAC configuration for small to mid-size commercial spaces. A split system has a condenser outside and an air handler or furnace inside, connected by refrigerant lines. A packaged unit combines both components in a single cabinet, usually on the ground or rooftop. Both types serve the same purpose but have different maintenance and repair considerations.
Split systems are found in offices, medical practices, retail stores, and restaurants where the outdoor condenser sits on a pad next to the building. Packaged units are common in strip malls and standalone commercial buildings. Both work well for spaces under 5,000 square feet — for larger spaces, rooftop units or VRF systems are usually more appropriate.
Common Problems We See
Refrigerant leaks (especially at indoor coil connections and service valves), compressor failures on units over 10 years old, condenser fan motor burnout from debris accumulation, blower motor failures, contactor and capacitor wear, and thermostat misconfiguration causing short-cycling. In the Bay Area, ground-level condensers are particularly prone to debris buildup from landscaping and foot traffic.
