How long will an AC Replacement take in Lexington, KY — and who needs a DHBC license?
- 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 AC replacements in Lexington require different permits or DHBC credentials?
- Commercial projects often require additional permitting and may need contractor classifications beyond residential DHBC trade licensure. Owners should confirm project-specific permit types and contractor qualifications with Lexington building officials. Large systems may also trigger mechanical or energy-code plan reviews under the 2021 IECC.
