Understanding the Basics: How Your AC Works 24 Hour Emergency Heating Service 24 7 Hvac Service Heating And Air Conditioning Service Near Me

Before diving into the specifics of troubleshooting a frozen AC unit, it’s helpful to understand the basic principles of how your air conditioner works. An AC unit essentially works by transferring heat from inside your home to the outside. This process involves several key components: Phoenix Air Conditioning Repair Ac Repair Company Near Me Heating & Air Conditioning Service Near Me

• Refrigerant: This is the chemical substance that absorbs heat as it evaporates and releases heat as it condenses. It circulates throughout the system.
• Compressor: The compressor is the heart of the AC unit. It pressurizes the refrigerant, raising its temperature and allowing it to release heat more efficiently.
• Condenser Coil: Located outside, the condenser coil releases the heat from the refrigerant to the outside air. A fan helps to dissipate the heat.
• Evaporator Coil: Located inside, the evaporator coil absorbs heat from the indoor air as the refrigerant evaporates. This cools the air that is then circulated throughout your home.
• Blower Fan: This fan circulates air across the evaporator coil, pushing the cooled air into your home’s ductwork.
• Expansion Valve (or Metering Device): This controls the flow of refrigerant into the evaporator coil, ensuring the proper pressure and temperature for efficient cooling.

When everything is working correctly, the refrigerant cycles continuously, absorbing heat inside and releasing it outside, keeping your home cool and comfortable. 24 Hvac Service Near Me Air Conditioning Repair Companies Near Me Heating And Ac Service Near Me

Why Does an AC Unit Freeze Up? 24 Hour Emergency Air Conditioning Service Near Me Near Ac Service Air Conditioning And Heating Services Near Me

The most common reason for an AC unit to freeze up is a lack of airflow across the evaporator coil. When the evaporator coil gets too cold, moisture in the air condenses on the coil and freezes. This ice buildup restricts airflow even further, leading to more ice accumulation and eventually a completely frozen coil. Here are the most frequent causes of this airflow restriction: Commercial Ac Repair Hvac Service Companies Near Me Heating Ac Service Near Me

1. Dirty Air Filter: This is the most common culprit. A clogged air filter restricts airflow to the evaporator coil, causing it to get too cold. Regularly replacing your air filter is a simple but crucial maintenance task. Commercial Air Conditioner Repair Commercial Hvac Service Near Me Home Heating Repair Service Near Me

2. Blocked Return Vents: Return vents are responsible for drawing air back into the AC unit to be cooled. If these vents are blocked by furniture, rugs, or other obstructions, it reduces airflow and can lead to freezing. Commercial Ac Companies 24 Hour Hvac Service Near Me Ac Hvac Repair Near Me

3. Dirty Evaporator Coil: Over time, dust and debris can accumulate on the evaporator coil, insulating it and reducing its ability to absorb heat. This can cause the coil to get too cold and freeze. Commercial Ac Repair Near Me 24 Hour Heating And Cooling Service Near Me Ac Guys Near Me

4. Low Refrigerant Levels: While less common, low refrigerant can also cause the evaporator coil to freeze. When the refrigerant level is low, the pressure in the system drops, which can lead to the coil becoming excessively cold.

5. Blower Fan Malfunction: If the blower fan isn’t working properly, it won’t circulate enough air across the evaporator coil, causing it to freeze. Commercial Aircon Servicing Ac Repair Companies 24 7 Air Conditioning Repair

6. Cold Outdoor Temperatures: Running your AC when outdoor temperatures are too low (typically below 60 degrees Fahrenheit) can also cause the evaporator coil to freeze. AC units are designed to operate within a specific temperature range. Commercial Air Conditioning Servicing Air Conditioning Repair Companies 24 7 Ac Repair Near Me
