01 — WHAT WE DO
The permit package, decoded
Three ACCA manuals, one right-sized system. Each answers a different question about your home.
02 — WHY SIZING MATTERS
A bigger unit is not a safer bet
Rules of thumb, like “500 square feet per ton,” routinely oversize equipment. Manual J replaces the guesswork with math on your actual house: orientation, windows, insulation, local climate.
OVERSIZED BY GUESSWORK
✕Short cycles: constant starts wear equipment out
✕Runs too briefly to dehumidify, so it is cold but clammy
✕Hot and cold spots between rooms
✕Bigger tonnage, bigger invoice, for worse comfort
✕Plan examiner kicks the permit back for real numbers
VS
RIGHT-SIZED BY MANUAL J
✓Long, quiet, efficient run cycles
✓Proper humidity removal in cooling season
✓Even temperatures, room to room
✓Equipment sized to the load, so you pay for what you need
✓Sails through plan review the first time
