- 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.

How long will a typical 'AC Replacement' take for Wilmington homes and what permits matter?
- 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 or large multi‑unit AC replacements in Wilmington need different permits than single‑family work?
- Yes. Commercial and multi‑unit replacements typically trigger additional permitting and plan‑review steps under the 2021 code. Projects may need engineered plans, mechanical drawings, and specified commissioning reports. Verify with the contractor which permits and submittals will be filed with the local building department before work begins.
