At Arctic Air Conditioning & Plumbing, we understand the frustration of dealing with an AC indoor unit freezing up, especially during the hot summer months. A frozen indoor unit not only disrupts your comfort but can also lead to potential damage to your HVAC system if left unaddressed. In this informative blog post, we'll delve into the causes of AC indoor unit freezing up and provide effective solutions to resolve this issue.
Restricted airflow due to dirty air filters, blocked vents, or closed registers can prevent warm air from reaching the indoor evaporator coil, causing it to freeze.
Insufficient refrigerant levels in the system can lead to a drop in pressure within the evaporator coil, resulting in its freezing. Refrigerant leaks or improper charging are common culprits.
Accumulation of dirt, dust, and debris on the evaporator coil can insulate it, hindering heat absorption and causing it to freeze.
A malfunctioning thermostat may cause the AC system to run continuously, leading to overcooling and eventual freezing of the indoor unit.
Problems with the indoor blower fan, such as a faulty motor or belt, can disrupt airflow over the evaporator coil, contributing to freezing.
Ensure air filters are clean and replace them regularly to promote proper airflow. Unblock vents and open registers to allow unrestricted airflow throughout your home.
Schedule a professional inspection by Arctic Air to check refrigerant levels and identify any leaks. Properly recharge refrigerant if necessary to maintain optimal levels.
Schedule professional evaporator coil cleaning to remove dirt and debris buildup, allowing for efficient heat absorption and preventing freezing.
Verify thermostat settings and calibration to ensure accurate temperature control. Replace a malfunctioning thermostat if needed to prevent overcooling.
Have our technicians inspect the indoor blower fan for any issues such as motor failure or belt wear. Repair or replace components as necessary to restore proper airflow.
