The acronym HVAC stands for Heating, Ventilation and Air Conditioning.

Best Hvac Thermometer
HVAC System

Why do we need such thermometer for HVAC system. People Says HVAC itself is a temperature or indoor weather controller so why is there such need of thermometers. A thermometer is needed for an HVAC system because it helps to regulate the temperature. The furnace uses the thermometer to determine when to turn on and off. The air conditioner uses the thermometer to determine when to turn on and off. The evaporator uses the thermometer to determine when to turn on and off. So whole of the system coordination needed proper temperature regulation that can be done by hvac thermometer.
