Quick answer
- Attach drawings, equipment lists, and access constraints.
- Require a line-item response to inclusions — crane, curb, controls, documentation.
- State how alternate manufacturers will be evaluated.
When this applies
You are soliciting multiple contractors
You need structured responses so the low number is not just the thinnest scope.
You were burned by change orders last project
Encode the surprises you hit — curb adapters, crane permits, after-hours fees — into this RFP.
Design is incomplete but budget is due
Say what is known, what is allowance, and how design-assist or alternates will work.
How it works
Describe intent, site, and constraints
Building use, occupied hours, crane limits, roof warranties, bilingual site rules, and blackout dates. Include photos of curbs and electrical service when drawings are thin.
List mandatory scope modules
Demo, new equipment, curb/adapter, duct transitions, electrical/gas, controls, start-up, Title 24 forms, TAB/Cx, training, warranty, and refuse. Require bidders to mark included/excluded per module.
Define evaluation and award
Price, schedule, relevant light-commercial experience, insurance, CSLB status, and clarification rounds. Reserve the right to interview — lowest price need not win if scope is incomplete.
Failure modes to avoid
Specifying “furnish and install HVAC” with no inventory
Every bidder invents a different job. Attach a schedule of equipment.
Silent exclusions on crane, curb, and documentation
Those three create the largest change orders on RTU work. Make them explicit.
Brand lock without an alternate path
If you allow alternates, say how equality is proven (capacity, efficiency, controls, warranty). If you require Bryant via an authorized dealer, say so — Precision can respond on that path honestly.
Proof & local context
- • Precision Heating & Cooling responds to commercial RFPs across San Jose / South Bay and Central Valley with transparent inclusions — CSLB #1056688, Bryant-authorized.
- • We will flag unclear scope in writing rather than win on omissions.
- • Perfection Guaranteed starts with a clear agreement about what “done” means.
Next step
Guidance reflects light-to-mid commercial HVAC, refrigeration, and server/edge cooling practice across San Jose / South Bay and Central Valley (Hanford, Clovis) jobs. Not for hospitals or hyperscale data centers. Confirm site conditions, Title 24 path, and manufacturer data before bidding.
FAQs
How detailed should the RFP be?
Detailed enough that two qualified contractors would price the same modules. If design is incomplete, use allowances and design-assist language rather than fake precision.
Should we require a site walk?
Yes for occupied roofs and kitchens. Mandatory walks reduce fantasy pricing and uncover access issues early.
What insurance and license items should we require?
Active CSLB license appropriate to the work, insurance certificates meeting your GC/owner minimums, and workers’ compensation. Ask for the license number on the bid form — Precision’s is CSLB #1056688.
