AC Replacement Company in San Jose: Costs, Permits & Service Answered
- 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 residential AC replacement contractors in San Jose also take small commercial jobs?
- Some residential contractors accept small commercial replacements, while others do not. Check each contractor's service description and licensing to ensure coverage of commercial scopes. For commercial work, request proof of experience with HVAC systems of similar size and ask about prevailing-wage or building-specific insurance requirements if applicable.
