Monday overview — AZ HVAC / mechanical

• 3 high-relevance HVAC / mechanical items (mostly school/facility; several just closed or closing soon)
• 2 adjacent facility / CMAR items where mechanical scope is plausible but not confirmed in the public abstract
• 1 major ADOT letting (highway) — low direct HVAC fit; included only as noise-filter example

Sources checked: ADOT Current Ads (cnsads.azdot.gov/current, last updated 9/16/2026 11:57 AM), Maricopa County BidNet Direct, Cartwright Bonfire notice, Aguila / Florence / Phoenix aggregator + portal references.

High — pure HVAC service

Scope summary

• FACT District RFP for HVAC maintenance and repair services covering cooling units at schools and district facilities.
• FACT Responses due online via Bonfire; contact named in public notice: Jazmin Shiner (Purchasing).
• ASSUMPTION Expect routine PM, corrective repair, and possibly filter/coil work typical of K–12 HVAC service contracts — confirm in RFP packet.
• ASSUMPTION Multi-site occupied campuses → after-hours / phased work likely; verify in specs.
• FACT Public notice published Aug 20, 2026.

Confidence: High on title/agency/due/portal. Scope depth beyond the notice headline is UNKNOWN without the Bonfire PDF. Title, due date, Bonfire URL, and “HVAC maintenance and repair” wording = FACT. Any claim about tonnage, brand standards, or bonding = ASSUMPTION / UNKNOWN.

High — capital HVAC conversion

Scope summary

• FACT Seeking a qualified general contractor for multipurpose-room HVAC conversion at Aguila Elementary.
• FACT (CLEATUS) Division 23 mechanical work; IMC/IPC/NEC compliance; asbestos inspection Jul 2024 reported no asbestos in sampled multipurpose/roof materials.
• FACT (CLEATUS) Funded with Arizona Division of School Facilities involvement referenced in summary; lowest responsible/responsive bidder framing.
• FACT (CLEATUS) Mandatory pre-bid site visit (Aug 11, 2026 cited); occupied campus — only visit opportunity.
• ASSUMPTION Mechanical sub under GC is the realistic path for most HVAC shops; confirm bid form allows listed subs.

Confidence: High that the project exists and is HVAC-titled. Exact equipment schedule (tons, refrigerant, controls) = UNKNOWN without OpenGov package. Note: CLEATUS page mixed unrelated Job Corps text in places — treat equipment details as needing primary-doc verify.

High — central plant / chillers

Scope summary

• FACT RFQ for construction services to replace a cooling tower and two chillers.
• FACT Each chiller minimum capacity 350 tons and 1,050 GPM; electrical 480V / 3-phase / 60 Hz.
• FACT Released ~Aug 14, 2026 per aggregator; addendum PDF referenced (RFQ_202607001_Addendum_1).
• ASSUMPTION QSLB path implies prequalification / select bidders list before hard bid — check district procurement rules.
• ASSUMPTION Large plant work → crane, rigging, electrical coordination, water treatment startup likely in full package.

Confidence: High on tonnage/GPM/electrical FACTS from aggregator description quoting scope. Official Florence portal URL = UNKNOWN in our fetch (Starbridge intermediary).

Medium — adjacent facility CMAR (mechanical likely)

Scope summary

• FACT Open solicitation titled “Durango Office and K-9 Facility” under CMR (construction manager at risk) designation on BidNet.
• ASSUMPTION New multipurpose MCSO office + K-9 facility typically includes full MEP (HVAC, plumbing, electrical) — not confirmed in the public list abstract alone.
• FACT Login/registration may be required on BidNet for full docs (list page visible without login).
• ASSUMPTION HVAC shops should watch for CMAR teaming / subcontractor outreach, not only prime bid.
• FACT Among 9 open Maricopa solicitations as of research pull Sep 16, 2026.

Confidence: Medium. Title + due + portal = FACT. Explicit HVAC scope language in abstract = UNKNOWN without BidNet packet. Label honestly: adjacent, not pure-HVAC confirmed.
