Understanding the Basics: How Air Conditioners Work 24 Hour Ac Company Ac Repair Around Me

Before we delve into the problems, it’s helpful to understand the basic principles of how an air conditioner works. At its core, an AC unit operates on a closed-loop refrigeration cycle. Here’s a simplified breakdown: Emergency Heating Repair Near Me 24hr Air Conditioning Service

• Refrigerant: A special fluid, known as refrigerant, is the lifeblood of the AC system. It absorbs heat from the air inside your home and releases it outside.
• Compressor: This is the heart of the system. It compresses the refrigerant, increasing its pressure and temperature.
• Condenser: The high-pressure, high-temperature refrigerant flows to the condenser (typically located in the outdoor unit). Here, it releases heat to the outside air and condenses back into a liquid.
• Expansion Valve: The liquid refrigerant then passes through an expansion valve, which reduces its pressure and temperature.
• Evaporator: The low-pressure, low-temperature refrigerant flows to the evaporator (located in the indoor unit). As it absorbs heat from the air circulating through your home, it evaporates back into a gas.
• Fan: Fans both inside and outside the unit circulate air across the evaporator and condenser coils, facilitating the heat transfer process.

When any part of this cycle is compromised, the AC’s ability to cool your home suffers. 24 Hour Emergency Heating Service Hvac Furnace Repair
