How much does commercial RTU replacement cost?

For light-to-mid commercial rooftops in the South Bay and Central Valley, a planned single RTU changeout commonly lands in the mid-teens to mid-forties (thousands of dollars installed) once you include equipment, curb adapter, crane, gas/electric tie-in, start-up, and Title 24 documentation — not just the unit sticker price. Multi-unit roofs and constrained crane access push higher; like-for-like after-hours swaps with clean curbs sit toward the lower end. These are planning bands for facility budgets, not a Precision bid.

These figures are typical South Bay / Central Valley planning bands for light-to-mid commercial scope — not a quote from Precision Heating & Cooling. Site conditions, crane access, and Title 24 path change the number.

Typical cost ranges

OptionTypical rangeNotes
3–7.5 ton like-for-like gas/electric RTU$14,000–$28,000Accessible curb, modest adapter, daytime or light after-hours window. Excludes major structural or duct redesign.
8–15 ton packaged RTU changeout$22,000–$45,000Typical retail / office / warehouse unit. Crane, adapter curb, economizer path, and commissioning drive the spread.
Multi-unit bundle (same crane day)Lower per-unit than solo liftsMobilization and street permits amortize across units. Still price each curb and electrical path honestly.
Emergency / failed compressor peak seasonPremium over planned workExpedite freight, after-hours labor, and temporary cooling can add a meaningful share of the capital cost.

What moves the price

  • Curb adapters, roofing tie-in, and deck repairs are the most common change-order sources on South Bay roofs.
  • Crane access, street permits, and solar/antenna conflicts can rival equipment cost on dense sites.
  • Gas pressure, disconnect sizing, and condensate routing must match the new platform.
  • Title 24 forms, economizer commissioning, and refrigerant documentation belong in the base bid — not punch list.
  • Central Valley peak-load summers favor planning changeouts in shoulder seasons to avoid emergency premiums.

When this guide applies

  • An RTU is end-of-life, chronically failing, or on an orphaned parts platform.
  • A TI, kitchen expansion, or office densification changes load or duct takeoffs.
  • You are bundling several units on one roof to share crane mobilization.
  • You need a capital planning number for next fiscal year — not a same-week quote.

Failure modes to avoid

  • Budgeting only the equipment invoice and discovering curb/crane costs at award.
  • Assuming a drop-in fit without field-verifying curb dimensions and structural capacity.
  • Skipping economizer / OA and Title 24 scope so the “cheap” bid fails inspection or comfort.
  • Treating a national average as a Bay Area or Central Valley installed number.

FAQs

Is this a quote from Precision Heating?

No. These are typical planning ranges for light-to-mid commercial RTU work in our South Bay and Central Valley markets. A real bid needs a roof survey, curb verification, and schedule assumptions.

Why do crane and curb so often blow the budget?

Many roofs need adapter curbs, roofing tie-ins, or restricted lift paths. Those line items are easy to omit in a lowball bid and expensive to add after award.

Does Bryant equipment cost more than generic RTUs?

Platform and efficiency tier matter more than brand slogans. Precision is Bryant-authorized; we specify what fits the load, curb, and controls — not an invented factory badge from another brand.

Can we phase replacements over multiple years?

Yes — prioritize by remaining life, efficiency, and tenant impact. Bundling lifts still helps when several units share a crane window.
