HVAC (Home Systems)
Heating, ventilation, and air conditioning — the system that maintains indoor temperature, humidity, and air quality. Failures range from comfort-only (thermostat, ceiling fan) to health-and-safety (combustion heating, ventilation) to water-damage (condensate drain, humidifier).
