Cool Calc and Amply Energy both appear on ACCA's approved software list for full residential Manual J, both with a LiDAR-capable devices note. They sell different delivery and billing models. LoadCalcStack does not rank a winner.

> Verified fact: Cool Calc homepage (retrieved 2026-09-26) lists Unlimited Pro at $50/user/mo for Unlimited Manual J, S, and D plus CoolCalc Scan LiDAR App and unlimited ticketed support. The same page also lists a $250/user/mo suite plan and $45/project.

> Verified fact: Amply Energy pricing page (retrieved 2026-09-26) lists Monthly at $200/user/month (1 month minimum; cancel any time) and Yearly at $2,160/user/year (save 10%; equivalent $180/user/month). The FAQ repeats those options and lists optional paid 1:1 onboarding at $50 with co-founder Eric.

> Verified fact: Cool Calc markets browser access on modern devices (Mac, PC, phone, or tablet) and CoolCalc Scan LiDAR options. Amply's pricing FAQ markets room-by-room iPad Pro LiDAR scans that build Manual J as you go, requires an Apple iPad Pro with LiDAR, and points Manual D work to existing duct tools plus Amply room loads.

> Verified fact: ACCA's approved software page (retrieved 2026-09-26) lists Cool Calc Manual J and Amply Energy under full residential load calculation, both with a LiDAR-capable devices note (Conduit Tech is listed the same way). Confirm the live ACCA list before relying on approval status.

> Editorial judgment: Choose Cool Calc when you want a published monthly web floor ($50/user/mo Unlimited Pro) plus browser / multi-device flexibility. Choose Amply when you want an on-site iPad Pro LiDAR Manual J workflow and accept the published $200/user/month (or $2,160/user/year) card. This is a posted web monthly floor versus a posted iPad LiDAR subscription — not a cheaper-versus-premium ranking. Normalize for users, hardware, modules, and training time before treating either number as "cheaper."

> Unverified: Hands-on accuracy, rebate/permit template acceptance by jurisdiction, and Amply seat/contract terms beyond the public cards were not independently verified.
