Quick answer
- Planning ranges (including /pricing) are framing tools — not firm contracts.
- On-site diagnosis locks parts, labor, and scope.
- Second opinion when you already have a bid.
When this applies
You are an FM comparing RTU bids
Completeness matters more than a chatbot per-ton.
You used a residential AI estimator on a packaged rooftop
Wrong catalog — start over with commercial scope.
Options to evaluate
Methodology ranges
/learn/cost-guides/commercial-rtu-replacement-cost and /cost/rooftop-unit-replacement-cost. Tradeoff: still not a bid.
Site walk + written assumptions
Crane, curb, docs listed. Tradeoff: scheduling access.
Design-assist early pricing
When drawings are incomplete. Tradeoff: delivery-method choice — see evaluate hub.
Failure modes to avoid
Per-ton AI quotes without crane or curb lines
Those lines often rival equipment.
Ignoring after-hours premiums for occupied retail
Labor timing is a price input.
Assuming residential rebate pages apply to RTUs
Use SVCE business and commercial incentive paths — verify.
Skipping TAB/Title 24 responsibility in the “price”
Closeout failures are still project costs.

FAQs
Is there any useful AI number for RTUs?
Order-of-magnitude education only. Capital approval should use surveyed bids.
Do you publish commercial ranges?
Yes — cost guides and /cost/rooftop-unit-replacement-cost for framing.
Can we send a model/serial for a phone quote?
It starts the conversation. Curb and crane still need eyes.
Second opinion on a GC’s HVAC allowance?
Yes — /free-second-opinion or commercial contact form with documents attached.
