How Central Air Conditioning System Works

HVAC 101

The same type of forced air occurs during both the winter and summer months with a typical furnace. A fan forces air through the system. A variable speed fan in your furnace improves heating and cooling efficiency. If you are in need of a new furnace, getting a furnace with a speed fan provides you better comfort and indoor air quality control. Once indoor air is pulled to the HVAC system.

Heat Pump Or Cooling Only System

This is how it works:

1. Keeping cool in the summer: Everything works the same with a normal A/C unit. If your system has a heat pump and fan coil, then air conditioning performs with the same refrigerant and the same process, etc.
2. 
   
3. Keeping warm in the winter: During the winter, the heat pump reverses the cooling process. Heat is extracted by the heat pump absorbing heat; it then heats the refrigerant and sends the heated refrigerant back inside to the fan coil where the coil then heats the air.
