Understanding how air conditioning works can help you make informed decisions about maintenance and repairs. An air conditioning contractor is key in ensuring that your system operates efficiently and effectively. Here’s a simplified explanation of the process behind air conditioning.
Air conditioning systems are designed to remove heat from indoor spaces and release it outside, cooling the air. The system operates through a cycle involving four main components: the evaporator coils, the compressor, the condenser coils, and the expansion valve.
The process begins with a return vent drawing warm indoor air into the air conditioning unit. This air passes over the evaporator coils, which contain a refrigerant—a fluid capable of absorbing and releasing heat. As the air moves across the coils, the refrigerant absorbs the heat, causing it to evaporate and turn into a gas.
The gaseous refrigerant then travels to the compressor, typically located outside. The compressor increases the pressure of the refrigerant gas, raising its temperature. The high-pressure, hot gas then flows to the condenser coils, releasing the absorbed heat to the outside air. As the refrigerant cools, it condenses back into a liquid.
The cooled, dehumidified air is then circulated back into the indoor space, creating a comfortable environment. The cycle repeats as long as the air conditioning system is running.
Regular maintenance by a qualified air conditioning contractor ensures that each component functions correctly and efficiently, helping to extend the lifespan of your system and maintain a pleasant indoor climate.
