HVAC and mechanical takeoff software

An HVAC takeoff starts with the schedules: units, fans, terminal boxes and air devices. The plans say where each one goes and what duct feeds it. The errors come from a tag on the plan that the schedule does not carry, or the reverse.

The conflicts we teach it first

These are the conflicts estimators in this trade tell us cost them money. They are the first rules we build with founding contractors.

    Schedule and plan disagree

    A VAV tag on the plan with no row in the schedule, or a scheduled unit that is never drawn.
  2. 02

    Spec and plan disagree

    The spec calls for one duct construction and a plan note allows another.
  3. 03

    Mechanical and life safety disagree

    A rated wall on the life safety plan with duct through it and no damper shown.
  4. 04

    Mechanical and structural disagree

    A rooftop unit on the mechanical plan with no curb or framing on the structural sheets.
  5. 05

    By others

    Controls, starters or line voltage wiring that the spec gives to another trade.
  6. 06

    Addenda

    A revised equipment schedule after you sent the first one out for quotes.

HVAC: common questions

Can I use Takeoff Tool for HVAC takeoffs today?
Not yet. HVAC is a founding trade. We build each trade with working estimators, so the tool learns how the trade really bids. Founding contractors use it free for three months while we build it with them.
What do you need from a founding HVAC contractor?
An hour or two of your estimator's time, screen shared, while they do a real takeoff. Plus a set of past bid packets with the finished takeoffs. We use them to check the tool against work you already trust.
What does it cost after the founding period?
The standard price is $2,500 per seat per month. It is a flat fee. There is no charge per takeoff.
