You bid a price the factory never agreed to hold
You bid it in March, released it in June, and it ships in February at whatever the factory is charging in February.
Other trades carry commodity price risk on material they can buy within days of needing it. You're carrying a price on a one-off manufactured object with a lead time longer than most of the schedule, quoted under terms that let the factory reprice at shipment. The same delay hits you twice, once on the invoice and once on the rigging, because the equipment has to come in during a short structural window that closes when the roof gets finished.
The size of it
You lose 3 to 8 percent on the largest line item on the job, and rigging that budgeted at $4,000 executes at $15,000. Behind that sits a building that can't be conditioned, so drywall can't start.
A commercial equipment quote is typically good for 30 days, and a lot of them carry price in effect at time of shipment language buried in the terms. Custom air handlers, large-tonnage rooftops, chillers, and VRF packages run well past 20 weeks and can stretch past a year. The GC sits on your bid for 60 to 90 days, the submittal cycle eats another 6 to 10 weeks, so the order releases months after bid and ships months after that. Every manufacturer increase in between falls on you, on a lump sum with no escalation clause. Then the slip breaks the crane pick, because rooftops get set on a date coordinated around dry-in, and a unit that misses that window gets flown over a finished roof or dragged up a shaft.

What hvac owners ask
Hvac equipment price increase between bid and shipment who pays?
You bid it in March, released it in June, and it ships in February at whatever the factory is charging in February.
What does it cost?
You lose 3 to 8 percent on the largest line item on the job, and rigging that budgeted at $4,000 executes at $15,000. Behind that sits a building that can't be conditioned, so drywall can't start.
What do I do first?
Put the quote expiration date and the price-at-shipment language, word for word, on the face of the bid summary, so the number carries its own shelf life.
What are hvac contractors supposed to be making?
HVAC runs 24% gross margin, 16% overhead and 8% net profit before taxes at $1M–$5M. The all-trade average is 7%, so this trade sits 1 points above it. The CFOS target is 11%.
Which part of the system fixes it?
The step is number 04, estimating system. The estimate maps one to one onto the job cost codes, so variance means something the day it appears. It comes from chapter 4 of CONTROL: The Construction Financial Operating System.
Josh Luebker ran commercial construction projects before he ran the numbers behind them, on data centres, military bases, hospitals, and high-rises. He wrote CONTROL: The Construction Financial Operating System, which is an eight-step framework for commercial subcontractors, and it publishes on October 1, 2026. He is a master electrician who moved into the office and kept the field vocabulary.
Sulphur Prairie Operations LLC maintains the benchmark reference behind these figures. Every edition is reconciled against the newest CFMA survey release before it publishes here. Where a figure changes between editions, the older edition keeps its year in the title so a citation to it stays correct.
