73 of the 179 active public K-12 and municipal HVAC projects across the Greater Los Angeles metro (Los Angeles, Orange, Riverside, San Bernardino, Ventura, Kern, and Santa Barbara counties) are still ahead of the public bid board: funded or in design, before the RFP ever posts. Only 6 are live bids today — roughly one on the board for every twelve moving toward it. Behind the pipeline sit 652 public buyers across 7 counties, led by 290 school districts.

Three California programs behind the work

  • CalSHAPE money is visibly working through this pipeline. The California Energy Commission's California Schools Healthy Air, Plumbing, and Efficiency Program funds HVAC assessment, maintenance, repair, and replacement in public schools — and it isn't an abstraction here: multiple early-stage projects in this dataset carry "CalSHAPE" in their titles, from district-wide controls upgrades to full ventilation replacements. When a state program pays for the assessment, the replacement project follows it into design and bid.
  • The federal relief era ended — and pushed the remaining work into local capital plans. ESSER funded a wave of school HVAC and indoor-air-quality work; with obligation deadlines now passed, districts that assessed and prioritized under federal relief are moving the unfinished list into bonds and local budgets — exactly the funded-and-designing stage where projects surface in SymplSignal.
  • Indoor air quality is a standing requirement, not a trend. EPA's Indoor Air Quality Tools for Schools guidance keeps ventilation performance on every facility director's list, and classroom IAQ scrutiny hasn't receded since the pandemic. Filter, controls, and ventilation upgrades recur on a cycle.
  • Every code cycle pushes replacements toward heat pumps. California's Title 24 Building Energy Efficiency Standards update every three years, steadily raising the efficiency and electrification bar — so like-for-like RTU swaps increasingly become heat-pump conversions with controls scope, on school and municipal buildings alike.

The buyer landscape

SymplSignal tracks 652 public buyers that procure K-12 or municipal HVAC work across the 7 counties of the Greater LA territory. School districts dominate — 290 of the 652, 44% of the market — followed by municipal governments (151) and public works departments (80). Buyer depth is greatest in Los Angeles County (161), with San Bernardino (80) and Orange (79) close behind. (499 buyers carry a specific county tag; another 153 are recorded at the metro-area level within these same seven counties and are included in the total.)

The pipeline

Of 188 tracked K-12 & municipal HVAC projects, 179 are active (anything not yet completed) and 73 are still ahead of the public bid board — funded, proposed, in design, or pre-bid, before a live solicitation posts. Against those 73 sit 6 live bids today. The mass of the early work is in pre-bid (21) and design-in-progress (19) — the highest-intent window before an RFP — with another 15 funding-approved: money in hand, design not yet underway.

The early-stage map does not mirror the buyer map: Riverside County ranks second for early-stage volume (11) despite ranking sixth for buyers, while Orange County — third in buyers (79) — shows just one mapped early-stage project right now.

On timing: activity has built steadily through 2026 — monthly project counts rose from 3 in January to 7 in each of May and June, the two largest months in the dataset. Most early-stage work does not yet carry a firm public date, so treat the calendar read as directional; the actionable signal is stage.

Representative early-stage projects

  • Orcutt USD District-Wide HVAC System Modernization (Campus-by-Campus RTU Replacement & Controls Upgrade): school district, early signal.
  • SBUSD District-Wide CalSHAPE HVAC Controls Upgrade: school district, design in progress.
  • Santa Maria Administrative Building HVAC Equipment Replacement: public works, early signal.

These are 3 of 73. The full ahead-of-bid pipeline, with owner, stage, and county for each, lives in SymplSignal.

How contractors use this

If you perform commercial or institutional HVAC work in Southern California: lead with the school districts — 44% of the buyer base, and the CalSHAPE paper trail tells you which campuses have assessed systems and funded scopes before any RFP exists. Prioritize LA and Riverside counties, where the early-stage volume concentrates — and note Riverside punches four spots above its buyer rank. Engage during funding-approved and design (the 34 projects with money or active design but no published RFP), and time bid-season capacity around the spring cluster the 2026 data shows. A live sample of what tracking surfaces here is on our California HVAC bids page, and Signal's K-12 & municipal HVAC coverage tracks all of it continuously.

Methodology

SymplSignal continuously tracks public-sector capital projects across the territory's 7 counties from primary public sources: board agendas and minutes, budget and bond documents, capital plans, and official notices. Active means any tracked project not yet completed (early-signal through under-construction). Ahead of the bid board means funded, proposed, in design, or pre-bid, upstream of any live public solicitation. Coverage for this territory × vertical is currently 41.4% of the estimated addressable buyer base and growing. Project dollar values are not reported: value data is not yet populated for this territory, and we do not estimate. Data current as of July 11, 2026. These figures describe SymplSignal's tracked dataset, not a census of all public work in the region.
