HVAC takeoff software for PDF mechanical plans
Upload the mechanical set and specs. EstimatorAI reads the sheets and schedules, pulls out equipment and air device counts, and answers questions about duct, piping and controls, so your takeoff starts from a first pass you can review.

This is EstimatorAI's general product walkthrough: upload plans, ask and review, export to Excel. It's an illustrative demo, not an HVAC project, and it doesn't show real project quantities.
What gets measured
| Item | Typical unit |
|---|---|
| Equipment such as rooftop units, air handlers, fan coils, VAV boxes and exhaust fans | Each (EA), by tag from the equipment schedule |
| Diffusers, registers and grilles | Each (EA), by type and size |
| Ductwork | Linear feet by size; rectangular duct is often converted to pounds of sheet metal |
| Duct insulation and wrap | Square feet (SF) |
| Fire, smoke and volume dampers, and duct fittings | Each (EA) |
| Refrigerant and hydronic piping | Linear feet by size, with fittings and valves each |
| Thermostats, sensors and controls points | Each (EA) |
Common pitfalls
- Missing equipment that appears only in schedules or details, not on the floor plan.
- Counting air devices without checking the schedule for sizes and neck sizes.
- Missing fire and smoke dampers where ducts cross rated walls shown on the architectural life-safety plans.
- Unclear controls scope between the mechanical contractor, the controls contractor and electrical.
- Skipping spec requirements for duct insulation, pressure class or sealing.
- Assuming curbs, supports and equipment power are by others without checking the notes.
How EstimatorAI handles it
Upload the mechanical sheets with the architectural, structural and electrical sheets and the spec book. EstimatorAI reads the set and gives you a first pass on equipment, air devices, dampers and piping that you can check against the drawings, then export to Excel and price in your own workflow. Questions you can ask:
- List every piece of equipment in the mechanical schedule with its tag and location.
- How many supply diffusers are on the second floor, by size?
- Where are fire dampers required?
- What does the spec require for supply duct insulation?
Frequently asked questions
Can EstimatorAI do an HVAC takeoff from PDF plans?
Yes. Upload your mechanical PDFs and specs, and EstimatorAI extracts equipment, air device and damper quantities and answers questions about the set. You review the first pass and export it to Excel.
Does it read equipment schedules?
Yes. You can ask for the equipment in a schedule by tag, type or location and check it against the plans.
Can it measure ductwork and piping?
EstimatorAI is strongest at reading the set: counts, schedules, sizes and spec requirements. Treat any duct or pipe length as a first pass and verify it against the scaled drawings before pricing.
Do I still need to review the takeoff?
Yes. EstimatorAI gives you a fast starting point, and an estimator should always check quantities against the drawings before a bid goes out.
Can I export the takeoff to Excel?
Yes. Export your quantities to Excel and keep pricing in the spreadsheets you already use.
How much does EstimatorAI cost?
Every plan starts with a 7-day free trial (card required). After the trial, EstimatorAI is $79/month, $149/quarter, or $499/year.
