What this directory is (and is not)

LoadCalcStack covers Manual J / ACCA-approved load-calc software for HVAC contractors. We cite vendor pricing pages with retrieval dates, note when pricing is available only by request, and link ACCA's approved software list as the authority for approval status.

This is not a consumer AC repair site and not a generic HVAC field-service management (FSM) directory. Manual J® is an ACCA trademark; LoadCalcStack is an independent directory brand.
