Message Estimating…
Bids come in faster than your estimators can count them. Operon HVAC’s take-off is completely automatic. It’s like hiring 100 more estimators for the price of one.
The unit, part by part
Every line on the schedule is a part on the roof.
Operon reads a mechanical set the way your estimator does: the rooftop unit and everything in it, the curb it sits on, and the gas, condensate and power runs that serve it, each counted and traced back to the sheet. Hover any part.
What it does
Schedules & specs
Conflicts caught before bid day.
Equipment schedules are checked against what is drawn, and the plans against Division 23, so mismatches and missing scope surface while there is still time to ask.

What did we carry for controls on our last three lab jobs?
All three carried controls as a subcontract quote. Two excluded BAS integration, and one carried an allowance for graphics.

Questions, answered.
Operon HVAC is automated HVAC take-off software for mechanical contractors. It reads mechanical drawing sets, counts equipment, duct, fittings, terminal units, diffusers, grilles, dampers and piping on every sheet, checks the counts against the schedules and the spec, and drafts RFIs for anything the drawings don’t settle.
Yes. Upload a drawing set and Operon HVAC counts it end to end, with no clicking symbols one by one. Your estimators review what it flags and price the job. It’s like hiring 100 more estimators for the price of one.
Operon HVAC’s take-off accuracy is 99%, and every quantity links to the sheet, region and symbol it was counted from, so anyone can check it in seconds. Anything measured from a printed scale stays provisional until a person confirms it.
Operon HVAC processes 1,000 pages in 8 minutes, so a full bid set is counted the same day it arrives.
Sign in at hvac.operonsolutions.com, or book a demo. Our engineers set up your workspace and your templates, and your first take-offs run within three weeks.
No. It produces the quantities and the evidence behind them; your estimators price them in the tools they already use. Exports are shaped to fit your templates.
Scale is read from each sheet and checked against known dimensions. Anything measured from a printed scale is marked provisional until a person confirms it.
Scope notes and responsibility matrices are read alongside the plans, and items marked by others or not in contract are kept out of your count.
No. Each company’s data is kept separate, encrypted in transit and at rest, and we never train models on it.
