What should Fond Du Lac homeowners ask before hiring an "AC Repair" contractor?
- 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 residential AC contractors in Fond Du Lac also handle light commercial systems?
- Some companies handle both residential and light commercial systems, but capabilities vary. Ask whether technicians are trained on commercial equipment, if larger refrigerant capacities are supported, and whether the contractor carries commercial-specific parts and permits.
