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 ($59/mo flat)
Starts at $59/mo annual ($79/mo monthly). 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 starting at $59/mo annual 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
14 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
$169
/mo flat
Best For
HVAC, General
Free Trial
14 days
Bottom Line: Still the fastest setup we've tested, but the 2026 pricing overhaul (Foundation $169/mo annual vs old $49/mo) ends its run as the budget pick. Now competes with Projul on value. Best for residential contractors who want AI estimating and digital takeoffs in one platform.
JobTread
Estimating, project management, and accounting — one tool, one price
Price
$199
/user/mo
Best For
General, HVAC
Free Trial
No
Bottom Line: No longer the flat-rate bargain it was - 2026 pricing ($199/mo + $20/user) makes it pricier than Projul for teams over 8. But built-in accounting, the new takeoff module, and QB Online sync keep it competitive for crews who want one tool. Solo operators should compare against Clear Estimates.
Clear Estimates
The cheapest estimating software that actually works - starts at $59/mo annual
Price
$59
/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.
