Load & DesignQuestion 19 of 110
Which condition would a technician correct by performing an accurate load calculation instead of using a rule of thumb like square footage per ton?
a.Chronic comfort complaints from an oversized or undersized system
b.A dirty condenser coil
c.A tripped float switch
d.A failed run capacitor
Explanation
Square-foot rules of thumb ignore insulation, glazing, orientation, and infiltration, often producing oversized or undersized equipment and comfort complaints. A Manual J load accounts for these variables and yields correctly sized equipment. This is the proper professional approach.
