Why Is My Air Conditioner Freezing Up?

Why Is My Air Conditioner Freezing Up?

As the summer heat rises, you rely on your air conditioner to keep your home cool and comfortable. However, one frustrating issue that homeowners may encounter is a freezing-up air conditioning unit. It not only disrupts the comfort of your home but can also lead to potential damage to your AC system.

At One Hour Heating & Air Conditioning, we understand the importance of a well-functioning cooling system. We’re here to provide the reasons behind this problem and offer solutions to get your AC back up and running again. Contact us today for all your HVAC repair services in Rowlett, TX, and surrounding areas.

Below Are The Most Common Reasons Why Your Air Conditioning Unit May Be Freezing Up:

• Insufficient Airflow:

One common reason behind a frozen AC unit is insufficient airflow. When the airflow is restricted, such as due to a clogged air filter, blocked vents, or closed registers, the reduced air movement can cause the evaporator coils to freeze. It’s crucial to ensure that your air filter is clean and debris-free and that all vents and registers are open and unobstructed.

• Low Refrigerant Levels:

Refrigerant is responsible for cooling the air within your AC system. If your air conditioner has low refrigerant levels, it can lead to improper heat exchange and cause the evaporator coils to freeze. Low refrigerant levels can occur due to leaks in the system, which a professional HVAC technician should address. Attempting to recharge the refrigerant without fixing the leak is only a temporary solution.

• Thermostat Issues:

Faulty thermostat settings can contribute to an air conditioner freezing up. If the thermostat is set too low, it can cause the evaporator coils to become excessively cold, leading to freezing. Ensure your thermostat is set at an appropriate temperature, typically around 72-78 degrees Fahrenheit, and that it functions correctly. If you suspect thermostat issues, our skilled technicians can inspect and calibrate it for optimal performance.

• Dirty Evaporator Coils:

Over time, dirt, dust, and debris can accumulate on the evaporator coils, impeding heat transfer and reducing airflow. When the coils become dirty, they are more prone to freezing. Regular maintenance, including coil cleaning, can help prevent this issue. Our professional technicians at One Hour Heating & Air Conditioning have the expertise to clean and maintain your AC system effectively.

• Damaged Fan Motor or Blower:

A malfunctioning fan motor or blower can disrupt the airflow, causing the evaporator coils to freeze. Faulty motors or blowers may not circulate air properly, leading to inadequate heat exchange and subsequent freezing. If you notice unusual sounds or reduced airflow from your AC unit, it’s advisable to have it inspected by a professional technician who can diagnose and repair any motor or blower issues. To avoid further damage to the unit, you can count on us to provide the best AC repair in Rowlett, TX, and surrounding areas.

A freezing-up air conditioner can be a frustrating problem, but understanding its causes can help prevent future occurrences. Remember to prioritize regular maintenance, including filter cleaning, coil maintenance, and professional inspections.
