How does a central air conditioning system work?
A central air conditioner works by using your furnace or air handler fan to draw warm air in through your home’s duct work. As the air is blown across the evaporator coil, which generally sits above your furnace, heat is removed from the air, cooling it down.
How does an air conditioner work explain in detail with diagram?

How does central heat and air work?
Simply put, a central gas heating system creates a cycle of warming cooler air. Burning propane or natural gas generates heat in the furnace’s burner. The heat produced passes through a heat exchanger, making it hot. Air from the home’s ductwork is blown over the heat exchanger, warming the air.
Why is the evaporator coil freezing?
One of the most common causes of a frozen evaporator coil is lack of system airflow. If there isn’t enough air blowing over your evaporator coil, the coil won’t have enough heat to absorb. This will cause the condensation on the coil to freeze over.
How to operate your central air conditioner more efficiently?
Keep It On. Don’t set the thermostat down low when you turn the unit on or make constant adjustments.
How to install a central air conditioning system?
