4 AC Components That Keep Your Home Cool in Charleston, SC

When it comes to keeping your Charleston, SC home cool and comfortable during hot summer months, your air conditioning system relies on various components working together. Let’s explore the essential AC components contributing to a cool indoor environment.

1. Compressor

The compressor is the heart of your AC system, as it circulates refrigerant through the system. Compressing the refrigerant raises its temperature and pressure, preparing it for the next stage of the cooling process. If the compressor doesn’t work, even if everything else is in good condition, you may need some repairs.

The compressor is in the condenser, the large metal box outside your home. The condenser works to release the heat into the outdoor air.

2. Air Handler

The air handler houses the evaporator coil and the blower fan. It is responsible for circulating cool air throughout your home. The blower fan pushes conditioned air through the ductwork into different rooms, consistently cooling and maintaining desired indoor temperatures.

The evaporator coil is part of the air handler. It holds the refrigerant and is responsible for absorbing heat from the surrounding air.

3. Refrigerant Lines

Refrigerant lines are the conduits that transport refrigerant between indoor and outdoor units. These lines ensure the continuous flow of refrigerant, allowing for effective cooling and heat transfer.

4. Thermostat

The thermostat serves as the control center of your AC system. It allows you to set and adjust the desired temperature, enabling you to regulate the cooling process according to your comfort preferences. Advanced thermostats also offer programmable and smart features for enhanced energy efficiency.


These AC components work harmoniously to keep your home cool and comfortable. Understanding how these components function can help you appreciate the complexity and importance of your AC system.
