- Commercial AC specialization. Provider lists commercial / rooftop-unit (RTU) / light-commercial cooling as a distinct service line, not a residential service stretched to fit.

What San Francisco homeowners actually ask about "AC Repair" — short answers for local conditions
- How is commercial AC repair different from residential?
- Commercial cooling means rooftop units (RTUs), lift or roof access, larger refrigerant charges, and downtime that costs the business by the hour. Jobs are bid on access and after-hours scheduling, not just tonnage — use a shop that documents real RTU and light-commercial work.
- Can a residential AC company fix my rooftop unit?
- Not always. RTUs have different controls, economizers, and access requirements than split systems. Confirm the contractor states commercial or rooftop-unit experience and can respond fast enough to limit business downtime before you rely on them.
- Do multiunit and commercial AC systems in San Francisco require different repair workflows than single-family systems?
- Yes. Multiunit and commercial systems involve shared ducting, access coordination, and sometimes different permit paths. Technicians evaluate ventilation impacts on neighboring units and may stage work to minimize tenant disruption. Confirm the provider's experience with multiunit repairs and any required building manager approvals.
