What Janesville homeowners ask most about hiring "AC Repair" pros
- 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.
- Can residential Janesville AC contractors handle small commercial systems?
- Some residential contractors service small commercial systems, while others focus strictly on homes. Confirm a contractor's commercial experience, insurance limits, and whether they have the tools for rooftop or packaged-unit work. Request references for similar commercial jobs when applicable.
- Do Janesville AC repairs usually require permits for refrigerant or compressor work?
- Permitting requirements vary by project scope and local rules. Janesville's known requirements focus on business licensing and bonding rather than specific municipal AC permits. Homeowners should ask the contractor whether the city or county requires a permit for the planned work and confirm who will obtain it.
