Common Reasons Your Air Conditioning Unit Might Freeze Up in Spokane Valley and Northern Idaho

1. Dirty Evaporator Coils
   • The dusty and pollen-heavy environment in Spokane Valley and Northern Idaho can quickly coat evaporator coils with debris, leading to freezing. Regular maintenance is crucial to prevent this buildup.
   • Solution: Ensure your coils are cleaned during annual maintenance checks to keep your system efficient.
2. Poor Airflow
   • Homes in the Spokane area often experience airflow issues due to blocked vents or poorly designed HVAC systems. This can be exacerbated by the frequent use of air conditioning during the hot, dry summers.
   • Solution: Regularly check and replace air filters, keep vents unblocked, and consider an airflow audit from Mainstream.
3. Low Refrigerant Levels
   • Older HVAC systems common in Spokane Valley homes might have leaks that reduce refrigerant levels, causing the unit to freeze.
   • Solution: Schedule a professional check to identify and repair leaks, and ensure refrigerant levels are properly maintained.
4. Thermostat Issues
   • The significant temperature fluctuations between day and night in Northern Idaho can cause improper thermostat settings, leading to AC freeze-ups.
   • Solution: Ensure your thermostat is set correctly and consider upgrading to a smart thermostat for better temperature management.
5. Fan Problems
   • In rural areas like Deer Park and Elk, debris from the outdoors can cause fan issues, leading to reduced airflow and freezing.
   • Solution: Regular inspections and cleanings can prevent fan malfunctions and ensure proper airflow.
6. Drainage Problems
   • The high humidity levels during certain summer periods in Spokane can lead to condensate drain blockages, causing freeze-ups.
   • Solution: Regularly inspect and clear your AC’s drainage system to prevent water backup and freezing.
7. Outdoor Temperature Extremes
   • Though less common, early summer cold snaps in the Spokane region can cause your AC unit to freeze if it’s running during unusually cool nights.
   • Solution: Avoid running your AC during cold weather and ensure proper system settings for fluctuating temperatures.

By addressing these common issues, you can keep your air conditioning unit running efficiently throughout the hot Spokane summer.
