Understanding AC Pressure Phoenix Air Conditioning Repair 24 7 Hvac Near Me Emergency Hvac Service Near Me

Before diving into the specifics of high-pressure issues, it’s essential to understand the basics of AC pressure. Air conditioning systems work by circulating refrigerant, a substance that absorbs heat from inside your home and releases it outside. This process relies on maintaining the correct pressure levels within the system. 24 Hvac Service Near Me Ac Repair Contractor Air Conditioner Repair Man

An AC unit has two primary pressure readings: 24 Hour Emergency Air Conditioning Service Near Me Air Conditioning Repair Contractor Hvac Emergency Repair Near Me

• Low-Side Pressure: This refers to the pressure in the suction line, which carries refrigerant from the evaporator coil back to the compressor.
• High-Side Pressure: This refers to the pressure in the liquid line, which carries refrigerant from the compressor to the condenser coil.

Normal operating pressures vary depending on factors like the type of refrigerant, ambient temperature, and system design. However, exceeding the recommended high-side pressure can indicate a problem. Commercial Ac Repair Same Day Hvac Service Near Me Air Con Repair
