Which HVAC Estimating Software Is Right for You?
Not every contractor needs the same tool. Here's our honest take based on your situation.
Solo HVAC operator doing residential service calls
→ Clear Estimates ($65/mo flat)
$65/mo flat. You don't need scheduling or dispatch — just fast estimates.
2–10 HVAC techs with dispatch management needs
→ Projul ($399/mo flat)
$399/mo flat saves $200+/mo vs per-user tools. Built-in scheduling and QuickBooks sync.
Commercial HVAC requiring blueprint takeoffs
→ Stack Construction ($183/mo)
No other tool comes close for digital measurements from PDF plans.

Our Honest Recommendation
Go with Projul
Best balance of price, features, and HVAC-specific tools for crews with 2–10 techs.
If you're a solo operator doing fewer than 5 estimates a month, Clear Estimates at $65/mo is smarter money.
Detailed Reviews: What We Found
Projul is our top pick. Here's why — and how the others compare.
Projul
Estimating, scheduling, and invoicing for trade contractors — flat-rate, no per-user fees
Price
$399
/mo flat
Best For
HVAC, Plumbing
Free Trial
14 days
Bottom Line: Our top pick for trade crews with 2–10 techs — but factor in the Core+ plan at $599/mo if you need QuickBooks sync or job costing. The flat-rate model still saves money vs. per-user tools. Skip it if you need digital takeoffs.
Stack Construction
STACK scores 4.6/5 — the best digital takeoff tool for commercial roofing, electrical, and HVAC contractors who bid from PDF blueprints.
Price
$183
/user/mo
Best For
HVAC, General
Free Trial
7 days
Bottom Line: The best digital takeoff tool we've tested. But starting at $2,999/yr for a single user ($250/mo), it's only worth it if takeoffs are your bottleneck. Teams of 3+ get volume pricing at $2,199/user/yr. Pair it with Projul or JobTread for scheduling.
Buildxact
Simple estimating and job management — ready in under an hour
Price
$49
/user/mo
Best For
HVAC, General
Free Trial
14 days
Bottom Line: Best bang for your buck if you're a small residential contractor who wants estimating + scheduling without a steep learning curve. Not for commercial work.
JobTread
Estimating, project management, and accounting — one tool, one price
Price
$99
/mo flat
Best For
General, HVAC
Free Trial
14 days
Bottom Line: Best value in this list. $99/mo flat with built-in accounting kills two subscriptions at once. But if you need QuickBooks or digital takeoffs, it's not the right fit.
Clear Estimates
The cheapest estimating software that actually works — $65/mo flat
Price
$65
/mo flat
Best For
HVAC, Small Crew
Free Trial
30 days
Bottom Line: Perfect for solo contractors who just need to crank out estimates fast and cheap. If you want scheduling or job management, spend more on JobTread or Projul instead.
