While most new homes built in and around the Rocky Mountain region have central air conditioning installed, many older homes to not. If you’re thinking of having central air conditioning installed, you may not fully understand how the system works.
Air is pulled into a system which is then cooled and dehumidified before it is sent into your home through the ductwork and out of each vent throughout your home. Because it uses your ducts, it is more efficient than setting up individual units in specific rooms.
A central air system consists of four components.
This is the metal unit that sits outside of your home. A high pressure gas is taken from the compressor, then converted into liquid by lowering the temperature to the saturation point. This process is a continual cycle within the condenser unit, and will contain both a mix of the gas and liquid.
The compressor controls the pressure of your air conditioning system, and is located within the condenser unit. The compressor compresses the low pressure gas created from the evaporator.
The evaporator is located near the air handler by your furnace. The evaporator absorbs heat from your living space.
This valve controls the amount of refrigerant allowed to flow into the evaporator coil. You’ll find this valve near the evaporator.
All components are connected by copper tubing that carries the refrigerant from place to place through a closed-loop cycle.
Once in place, heat can be removed through the indoor evaporator and sent outdoors to the condenser.
Is this the year you install a central air conditioner in your home?
