Understanding the Basics: How an AC Unit Works Emergency Heating Repair Near Me Ac Repair Around Me

Before diving into the repair process, it’s helpful to understand the fundamental principles of how an AC unit operates. The core components of an AC system include: 24 Hour Emergency Heating Service 24hr Air Conditioning Service

• Compressor: This is the heart of the system, compressing the refrigerant and circulating it throughout the system.
• Condenser Coil: Located outside, this coil releases heat from the refrigerant, turning it from a gas to a liquid.
• Evaporator Coil: Located inside, this coil absorbs heat from the air, cooling it down.
• Refrigerant: This is the fluid that absorbs and releases heat, circulating throughout the system.
• Expansion Valve: This valve controls the flow of refrigerant into the evaporator coil.
• Blower Motor: This motor circulates air across the evaporator coil and throughout your home.
• Ductwork: The network of ducts that distributes the cooled air.

The AC unit works by cycling refrigerant through these components. The refrigerant absorbs heat from the air inside your home, cools the air, and then releases the heat outside. Phoenix Air Conditioning Repair Hvac Furnace Repair

Why Your AC Unit Freezes: Common Causes 24 Hvac Service Near Me Ac Heater Repair

A frozen AC unit indicates a problem with the heat exchange process. Several factors can cause the evaporator coil to freeze: 24 Hour Emergency Air Conditioning Service Near Me Air Conditioning Heating Repair

1. Restricted Airflow: This is the most common cause. When airflow across the evaporator coil is insufficient, the coil can become too cold and freeze. This restriction can be due to: Commercial Ac Repair 24 7 Air Conditioning Service

   • Clogged Air Filter: A dirty air filter restricts airflow.
   • Blocked Air Vents: Closed or blocked vents limit airflow.
   • Frozen Evaporator Coil: Ice buildup on the coil itself further restricts airflow.
   • Obstructions in Ductwork: Kinks, debris, or collapsed ductwork can impede airflow.
   • Blower Motor Failure: If the blower motor isn’t functioning properly, it won’t circulate air across the coil.

2. Low Refrigerant Levels: Refrigerant is essential for heat absorption. Low refrigerant levels can cause the evaporator coil to freeze because the refrigerant is not absorbing enough heat. This can be caused by: Commercial Air Conditioner Repair 24 7 Ac Service

   • Refrigerant Leaks: Leaks in the refrigerant lines or components can lead to low refrigerant.
   • Improper Charging: If the AC unit was not charged with the correct amount of refrigerant during installation or servicing, it can freeze.
