PM contract vs demand for a 4-store c-store operator: the math

Modeled fleet: 4 stores in Hillsborough/Pinellas, each with one beer cave, one foodservice walk-in, 8–12 glass-door merchandisers, one frozen drink machine, one ice machine, one ice merchandiser, plus hot-side equipment. Mix of 5- to 12-year-old equipment, mostly True and Beverage-Air on glass-door, FBD on frozen drink, Manitowoc on ice. This is a representative Tampa Bay 4-store profile.

Emergency calls: 14–22 calls/year fleet-wide at $380–680 each = $5,300–15,000. Compressor or major refrigeration failures: 2–4 events/year fleet-wide at $2,400–4,800 each = $4,800–19,200. Refrigerant top-offs (uncontracted leak management): $800–2,400 fleet-wide. Product loss from preventable failures: $1,200–4,800. Total demand-only spend: $12,100–41,400 annually. Plus operational downtime cost not captured in line items.

Quarterly PM (4 stores × 4 visits): $4,800–11,200. Monthly contract base: $1,200–3,200/month = $14,400–38,400 annually (includes ColdSentry™ monitoring, ArcticOS™ portal, contract-rate emergency service). Emergency calls at contract rates: 8–14 calls/year (fewer because PM prevents most) at $230–440 each = $1,800–6,200. Compressor failures: 0–2 events/year (most prevented by PM) at $2,400–4,800 = $0–9,600. Total contract spend: $21,000–65,400 annually.

On paper, contract spend exceeds demand-only spend in many years. The math shifts when you include the events PM prevents: catastrophic failures during peak weekends, FDACS findings from missed equipment temperature, refrigerant phase-out emergencies, customer-facing downtime during summer. These are tail-risk events that demand-only operators absorb 1–2 times per 5-year window at $15,000–60,000 each. Contract operators absorb them rarely.

(1) ColdSentry™ continuous monitoring catches drift before it's customer-facing. (2) ArcticOS™ portal centralizes service history across stores so the regional manager has visibility. (3) Quarterly PM walks address the canopy condenser, gasket, and strip-curtain failures that drive most preventable summer failures. (4) Contract-rate emergency service when failures do happen. (5) Defined response targets by site tier and severity.

Single-store operators with new equipment (under 4 years old), low foodservice exposure, and disciplined operational PM (clerk and manager walks done correctly) can run demand-only. The math doesn't favor contract until the operator faces 4+ emergencies per year or runs aging equipment.

Multi-store operators (3+ stores), aging fleets (40%+ of equipment over 8 years), foodservice programs with FDACS exposure, coastal stores with salt-air maintenance load, and operators planning AIM Act phase-down capex over the next 3 years. All of these favor the contract structure.

4-store operator running demand-only, modeled across 5 years: $90,000–180,000 cumulative spend including 2–3 catastrophic failure events. Same operator running service contract: $115,000–290,000 cumulative spend, 0–1 catastrophic failure events, lower customer-facing downtime, full FDACS documentation trail. The contract saves money in 3 of 5 years modeled and dramatically reduces year-to-year variance.
