The most common installation mistake in the HVAC industry isn't a wiring error or a refrigerant overcharge — it's putting in the wrong size system. Oversized systems short-cycle, fail to dehumidify properly, and wear out faster. Undersized systems run constantly and never keep up on the hottest Alabama days.
Both problems are caused by contractors who size systems by square footage alone — a shortcut that ignores the factors that actually determine your cooling load: insulation quality, window area and orientation, ceiling height, local climate data, and ductwork condition.
AirPros performs a Manual J load calculation on every installation — the industry standard methodology that accounts for all of those factors. It takes more time upfront. It produces a system that performs correctly, runs efficiently, and lasts as long as it should.
