6 reviews
"The ductwork counts are spot-on. I still verify everything, but it's way faster than starting from scratch. Cut my takeoff time in half and I can bid more jobs now."
"The equipment schedules alone are worth it. AI pulls all the unit specs and tonnages—I just verify and price. My estimator can focus on the complex parts instead of counting diffusers all day."
"We run every plan through TakeoffBuilder first, then verify the flagged items. The bulk count is reliable—we just focus our time on the edge cases that actually need human judgment."
"The export to Excel is perfect. I import into Accubid and add my pricing. No retyping, no transcription errors. Clean workflow from upload to finished bid."
"First takeoff was free so we tested it on a project we'd already done manually. AI count was within 3% of ours. That sold us. Now it's part of our standard process."
HVAC Takeoff Questions
Common questions about AI-assisted HVAC takeoffs, accuracy, pricing, and workflow integration.
How accurate are HVAC takeoffs?
On commercial HVAC plans, we achieve 94-96% accuracy compared to manual takeoffs. The AI understands mechanical symbols, equipment schedules, and ductwork layouts. Accuracy varies by plan quality—cleaner PDFs with standard symbols work best.
- AI flags uncertain items for manual review
- You verify counts before finalizing your bid
How fast do I get my HVAC takeoff?
Typical turnaround is 10-15 minutes for standard commercial plans. A 30-page mechanical set usually completes in under 12 minutes. Larger plan sets may take 20-25 minutes. You'll get an email when your takeoff is ready.
- Email notification when analysis completes
- Download immediately or access anytime
What format do I get my HVAC material list in?
Download as Excel or CSV. Counts are organized by system and zone, matching standard HVAC estimating workflows. Import directly into your existing estimating software like Accubid or PlanSwift, or use as-is for manual pricing.
- Compatible with major estimating software
- Organized by zone and system for easy pricing
Will it work on my HVAC plans?
We work best on commercial HVAC plans with standard mechanical symbols. Residential plans work well too. Hand-drawn markup, unusual custom symbols, or very low-resolution scans may reduce accuracy. The cleaner the PDF, the better the results.
- First takeoff free on plans under 20 pages
- Test with your own plans before buying credits
How much does an HVAC takeoff cost?
Pay-per-use with credits. A typical 50-page commercial HVAC set costs 3 credits. No subscription, no monthly fees. Buy credits when you need them—they don't expire. First takeoff is free on plans under 20 pages so you can test it.
- Credits never expire
- Only pay when you use it
Should I verify the HVAC counts?
We recommend spot-checking, especially on your first few takeoffs. Compare a section manually to build confidence. The system flags items with lower confidence for your review. Most contractors find they can trust the bulk count and just verify flagged items.
- Smart flagging highlights items needing review
- Build confidence with test takeoffs
