Understanding Why Your AC Unit Freezes 24 Hour Emergency Heating Service Hvac Service Companies Near Me 24 7 Ac Repair

Before diving into the repair process, it’s crucial to understand the factors that contribute to a frozen AC unit. The primary culprit is a lack of airflow, which prevents the evaporator coils from absorbing heat properly. When this happens, the refrigerant inside the coils becomes too cold, causing moisture in the air to freeze on the coils. Here’s a breakdown of the most common causes: Phoenix Air Conditioning Repair Commercial Hvac Service Near Me 24 7 Air Conditioning Repair

1. Dirty Air Filter: A clogged air filter is the most frequent cause of a frozen AC unit. When the filter is dirty, it restricts airflow, forcing the AC to work harder and reducing the amount of warm air passing over the evaporator coils. This leads to a drop in coil temperature and subsequent ice formation. 24 Hvac Service Near Me 24 Hour Hvac Service Near Me 24 7 Ac Repair Near Me

2. Restricted Airflow: Besides a dirty filter, other obstructions can hinder airflow. Blocked vents, closed registers, or even furniture placed in front of air vents can restrict the circulation of air, causing the same issues as a dirty filter. 24 Hour Emergency Air Conditioning Service Near Me 24 Hour Heating And Cooling Service Near Me Commercial Hvac Repair Near Me

3. Low Refrigerant Levels: Refrigerant is the lifeblood of your AC system, responsible for absorbing heat and cooling the air. If the refrigerant level is low due to a leak, the pressure inside the system drops, causing the evaporator coils to become excessively cold and freeze. This is a more serious issue that requires professional attention. Commercial Ac Repair Hvac Repair Contractor Ac Fixing

4. Faulty Blower Motor: The blower motor is responsible for circulating air across the evaporator coils and into your home. If the blower motor malfunctions or fails, airflow is significantly reduced, leading to ice formation. Commercial Air Conditioner Repair Ac Repair Companies Heating Repair In My Area

5. Low Outdoor Temperature: Running your AC when the outdoor temperature is too low (typically below 60 degrees Fahrenheit) can also cause the evaporator coils to freeze. Most AC units are not designed to operate efficiently in cold weather. Commercial Ac Companies Air Conditioning Repair Companies Air Conditioning Specialist Near Me

6. Dirty Evaporator Coils: Over time, the evaporator coils can accumulate dust and debris, acting as an insulator and preventing proper heat transfer. This can lead to the coils becoming too cold and freezing up. Commercial Ac Repair Near Me 24 7 Hvac Near Me Local Air Conditioning Service
