Understanding Air Pressure in Your AC System 24 Hour Ac Company Residential Air Conditioning Repair Emergency Hvac Service Ac Guys Near Me

Before we dive into troubleshooting, it’s essential to grasp the fundamental role of air pressure in your AC system. The AC system operates on the principle of refrigerant circulating through a closed loop, transferring heat from inside your home to the outside. This process relies on the refrigerant changing state between a liquid and a gas, driven by pressure changes. Emergency Heating Repair Near Me Ac Service Near Ac Repair Around Me 24 7 Ac Repair

• High-Pressure Side: This side of the system is where the refrigerant is compressed, increasing its temperature and pressure. This high-pressure, high-temperature refrigerant then flows through the condenser, where it releases heat into the outside air.
• Low-Pressure Side: After passing through the condenser, the refrigerant expands, decreasing its temperature and pressure. This low-pressure, low-temperature refrigerant then flows through the evaporator, where it absorbs heat from the inside air, cooling your home.

Proper air pressure is crucial for the efficient operation of this cycle. If the pressure is too low, the system may not be able to effectively cool your home. If the pressure is too high, it can damage the components of the system. 24 Hour Emergency Heating Service 24 7 Hvac Service Near Me 24hr Air Conditioning Service 24 7 Air Conditioning Repair
