A 50-school district running a refrigeration fleet of 250–400 units faces a binary: contract scheduled PM, or pay demand-only and absorb the emergency calls. Five-year math, with realistic Tampa Bay numbers, says the contract pays back at scale on emergency-call avoidance alone.
50-school K-12 district. 50 walk-in coolers, 50 walk-in freezers, 200 reach-ins, 50 milk coolers, 50 ice machines, 50 prep tables, 50 kitchen RTUs. Roughly 450 units in service.
Equipment age distribution: 40% under 8 years, 35% 8–13 years, 25% over 13 years. Tampa Bay average for a district that hasn't had a major capital reset.
Average demand-only service call: $325–650 per visit including travel and after-hours premium. Average emergency-call frequency on a fleet this size with no PM: 110–180 calls/year.
Annual demand-only spend: $40,000–110,000. Add equipment failures that escalate to capital replacement faster than necessary: another $35,000–80,000/year in accelerated capex.
Quarterly PM on every unit plus monthly condenser cleaning during summer. Service contract pricing for a 450-unit district fleet in Tampa Bay typically runs $90,000–150,000/year.
Demand-call frequency drops 50–70%; remaining calls are covered under the contract's allotment. Emergency response targets are agreed in writing.
Avoided demand calls (50 fewer/year at $450 avg): $22,500/year saved. Avoided emergency capital escalation (15% of accelerated capex avoided): $5,000–12,000/year saved. ENERGY STAR-grade efficiency from clean condensers and right-sized refrigerant: $8,000–16,000/year saved on a 450-unit fleet.
NSLP / FDACS audit-readiness: harder to monetize, but a single major audit finding can cost the district $25,000–150,000 in corrective action. Avoid one and the contract pays for itself.
Demand-only baseline: $375,000–950,000 over 5 years.
Scheduled PM contract: $450,000–750,000 over 5 years (contract cost) minus $175,000–220,000 in avoided demand and capital cost = net $230,000–575,000.
Net difference: contract typically wins by $50,000–250,000 over 5 years on the 450-unit fleet, before counting audit avoidance.
Continuous monitoring on every walk-in adds $300–600/year per unit but cuts emergency calls another 30–50% by catching drift before failure. On a 450-unit fleet, payback is 18–24 months.
ArcticOS centralizes the records auditors want. The director of nutrition services pulls a 12-month CSV in 90 seconds during an FDACS visit.
Small districts (under 10 schools) with newer equipment and in-house facilities staff capable of basic PM may pencil demand-only. The threshold is roughly 80–100 units in service; below that, contract overhead starts to eat the savings.
For Tampa Bay districts of any meaningful size, contract typically wins.
Hillsborough County Public Schools, Pinellas County Schools, and Pasco County Schools have all run different mixes of contract and in-house service over the past decade. The trend is toward consolidated multi-year contracts with monitoring built in.

Roughly 80–100 units in service, given Tampa Bay labor and energy rates. Below that, demand-only is competitive; above, contract typically wins.
$90,000–150,000/year for a 450-unit fleet (50 schools). Scales with unit count, age, and refrigerant mix.
Continuous monitoring adds $300–600/year per unit but cuts emergency-call frequency another 30–50%, with 18–24 month payback on a district fleet.
