Priced exposure analysis

Four rooftop units, identified from aerial imagery and public records: what you have, what drives its cost, what a failure costs, and what it costs to hand that risk to us.

Step 2 of 4Cost and risk factors
01

Where your building type sits

Distribution and light industrial is the gentlest occupancy for rooftop HVAC: low internal load, no kitchen exhaust, no process heat, long stretches near-empty. How you use the building runs in your favor.

What stage your equipment is at

Against an 18 year expected life, RTU-4 sits at 33%, RTU-3 at 61%, RTU-2 at 83% and RTU-1 at 133%. Past year ten, frequency and severity climb together and the constraint shifts from parts wearing out to parts getting scarce.

How the repair landscape is changing

Every input on a repair bill is rising, and contractor markup compounds supplier increases before they reach you. Three of your four units run on refrigerants being phased out, which is where parts are scarcest and quotes highest. A repair quoted today is the cheapest it will ever be.

Illustrative index built from regional service pricing.
Parts
Major OEMs raised commercial parts pricing up to 8% in 2026, largely on tariffs.
Labor
Rates climb against a tightening trade labor pool, and the truck roll bills the same whether the fix takes an hour or five.
Scale
At four units you carry no volume leverage. Nobody discounts a four-unit account.
Refrigerant is the sharpest edge. Installed cost has roughly doubled in three years as EPA allocations step down. RTU-1 runs on R-22, banned from US production in 2020, so parts for a 24-year-old unit are often unavailable. RTU-2 and RTU-3 run on R-410A, a decade behind: new equipment ended January 2025 under the AIM Act, supply tightening 85% by 2036. Only RTU-4 is on the current standard.
04

What your climate demands

Your units carry cooling load nine months a year, peaking in August. Unlike a dry climate, humidity holds overnight temperatures up, so compressors run through the night instead of unloading. Salt-laden humid air accelerates corrosion on coils, cabinets and electricals.

Step 3 of 4Exposure assessment

Equipment lifecycle bar, with each unit plotted against it

Zones mark the age bands where each class of failure becomes more prevalent.

RTU-4 6 YR 40% RTU-3 11 YR 73% RTU-2 15 YR 100% RTU-1 24 YR 160% 0510152025 EARLY LIFE RISKS Capacitor fails Contactor pits Belt slips Condensate drain blocks Condenser fan motor Control board fails MID LIFE RISKS Blower assembly fails Bearing failures Compressor fails Condenser coil leaks Evaporator coil leaks TXV sticks PAST EXPECTED LIFE RISKS Parts obsolete Refrigerant phased out Repair exceeds value Replacement only
Ages are shown against a 15 year expected life. Past that point, parts availability replaces wear as the constraint.

Repair cost range per unit, with replacement cost

Each bar spans what a single work order can cost on that unit, shaded from minor part to major component. The tail past it is a worst case (multiple parts/components, after-hours call-out, multiple follow-ups, etc.) and the column at right is full replacement.

TYPICAL REPAIR COST RANGE IF REPLACED RTU-1 7.5 TON · R-22 $20,250 NO REPAIR PATH RTU-2 7.5 TON $20,250 RTU-3 5.0 TON $13,500 RTU-4 4.0 TON $10,800 $0$2K$4K$6K$8K$10K$12K$14K MINOR REPAIR (CONTACTOR, CAPACITOR, ETC.) MAJOR REPAIR (COMPRESSOR, COIL, ETC.) WORST REALISTIC CASE
RTU-1 has no middle. Parts for it are no longer made, so its next major failure is not a repair; it is a replacement. That gap, not the age, is what makes it terminal. Ranges cover the 31 most common rooftop failures, priced to each unit’s size; worst case assumes two major failures at once.

Step 4 of 4Cost certainty program
The program

Your repair spend, locked flat. One number for all four units.

Four units cannot average themselves out. One compressor is your whole year. We take that variance onto our book and hand you a fixed price. You keep your provider; we review and pay the invoices.
