If you manage a commercial building in Fresno or Clovis, you know rooftop HVAC units don’t last forever. The question isn’t if you’ll need to replace them—it’s when, and how much you should set aside.
Most facility managers get vague answers about commercial rooftop HVAC replacement cost Fresno. Contractors say “it depends” or “call for a quote.” That’s not helpful when you’re building a capital budget or justifying a six-figure line item to ownership.
What Drives Commercial Rooftop Replacement Cost
Four factors control what you’ll pay:
Tonnage. Bigger equipment means higher material cost and longer install time. Most commercial rooftops run 5 to 25 tons per unit.
Unit count. Replacing six units in one project brings economies of scale—shared crane time, bulk pricing, and lower per-unit labor cost.
Roof access. If a crane can park next to your building and lift straight up, installation is faster and cheaper. Courtyard locations or power line obstructions cost more.
Typical Cost Ranges for Fresno Rooftop Jobs
Here’s what facility managers in the Fresno market should budget, including equipment, labor, crane, electrical connections, and startup:
- Single 5-ton unit: $12,000–$18,000
- Single 10-ton unit: $18,000–$28,000
- Single 15-ton unit: $28,000–$42,000
- Single 20-ton unit: $38,000–$55,000
- Multi-unit project (3–6 units, 10–15 tons each): $75,000–$200,000
These ranges assume standard gas/electric packaged units and straightforward roof access. If your roof needs reinforcement or ductwork modifications, add 15–30%.
A Fresno HVAC contractor working with repeat commercial clients will price differently than one-off jobs, but now you have a baseline. If someone quotes $8,000 for a 15-ton replacement, it’s incomplete. If they quote $60,000 for a single 10-ton unit, you’re being overcharged.
Why Crane Access Adds Cost—and How to Budget for It
Crane cost surprises more facility managers than any other line item.
If your building has good access and the contractor can replace multiple units in one crane day, the per-unit cost drops. Replacing six units in one day spreads that $5,000 crane bill across six installations.
Difficult access—courtyard units, overhead power lines, narrow alleys—requires larger cranes, street closure permits, or multiple setups. That pushes cost higher.
Walk the site with your contractor before you get a quote. Ask about overhead obstructions, permit requirements, and whether multiple units can share one crane day. Get crane cost broken out as a separate line item.
Phased Replacement and Financing Options
If you manage multiple buildings or eight rooftop units, replacing everything at once might not be realistic.
Phased replacement spreads capital expense across two or three budget cycles. You replace the oldest units first, then tackle the rest as they age out. The trade-off: phased projects cost slightly more per unit because you’re paying for crane access multiple times.
A family-owned, 30+ years contractor can help structure a replacement plan that fits your budget cycle.

Q: How long does a commercial rooftop unit last before it needs replacing?
A: Most packaged rooftop units run 15–20 years with regular maintenance, though Fresno’s long, intense cooling season can shorten that if the system is undersized or poorly serviced.
Q: Can rooftop units be replaced without shutting down the business?
A: In most cases yes—replacements are scheduled off-hours or unit-by-unit so at least partial cooling stays online during business hours.
Q: Is it cheaper to replace all rooftop units at once or one at a time?
A: Replacing in bulk usually lowers per-unit labor and crane cost, but phasing spreads out capital expense—the right call depends on how close the remaining units are to failure.
