HVAC comes with its own vocabulary. Here are the terms you are most likely to hear, explained simply.
Sizing and efficiency
Tonnage measures cooling capacity (one ton ≈ 12,000 BTU/hr). SEER2 measures cooling efficiency — higher is more efficient. A load calculation is the measurement process that determines the right size for your home.
Equipment and parts
A heat pump cools and heats from one unit. An inverter (variable-speed) system modulates output instead of running full-on/off. The condenser is the outdoor unit; the evaporator coil and air handler are indoors. The capacitor and contactor are common electrical parts that wear out.
