- Commercial RTU specialization. Provider names rooftop-unit / packaged-unit / light-commercial replacement with scope detail (crane set, curb adapter, economizer) — not a residential job description.
- Manufacturer authorization. Factory-authorized status on commercial equipment preserves the warranty and reflects factory training.
- Google rating. A strong rating floor is the minimum trust threshold for commercial work.

Which AC Replacement questions do West Allis homeowners ask most — and what the answers are?
- How is commercial AC replacement different from residential?
- Commercial work usually means packaged rooftop units (RTUs) that need crane access, curb adapters, and electrical and controls integration, and it's priced by tonnage rather than a flat residential range. Look for an installer who documents RTU experience, not a residential shop scaling a job up.
- How is commercial replacement priced?
- Mostly by tonnage, plus crane set, curb adapter, electrical, and any controls or economizer work. Smaller 3–5 ton rooftop units and larger 7.5–10 ton units sit in very different ranges, so get an itemized, per-unit quote that separates the equipment from the access and crane costs.
- Do commercial and residential AC replacement rules differ in West Allis?
- Yes. Commercial AC replacements often trigger different permit and bonding thresholds and may require project-level plans or inspections. Business-license and bonding requirements still apply, but large commercial projects can involve additional inspections and coordination with the city's building department. Confirm scope and permitting responsibilities in writing before work begins.
