The central air conditioning system is one of the major home appliances. They differ from model to model, but their basic operation remains the same. This video shows how central air conditioning works.
A central air system comprises a condensing unit that sits outside the home. They circulate conditioned air throughout rooms or spaces through ductwork.
The main components include a fan unit, compressor, condenser coil, evaporator coil, expansion valve, and thermostat.
A central air conditioner draws cool air into your home through your furnace or air handler. Once inside your house, the air passes over the condenser coil. Then refrigerants compress air molecules, making them smaller. This creates low pressure inside the unit and causes evaporation. The water vapor goes through the coils and becomes liquid again, absorbing heat from the air before being released back into your home.
A sound HVAC system works hard to keep your home comfortable and energy efficient. But if something goes wrong, it’s important to identify signs of trouble so you can call for help from HVAC repair services.
