Why Is My Allergen Testing (dust Mites, Pet Dander, Pollen) Freezing Up? | Ar Fixes

Ar’s #1 Solution for Frozen Allergen Testing (dust mites, pet dander, pollen) Coils

When your indoor air quality testing ices over in Ar’s humidity, Indoor Air Quality Testing Pros follows this proven 5-step repair process:

1. Diagnose root cause (low refrigerant? dirty filter?)
2. Thaw system safely
3. Fix underlying issue
4. Test pressures
5. Prevent future freezing

Common Ar-specific causes we find:

• Oversized units (common in 90s Ar homes)
• Clogged drain lines from local pollen
• Undersized ductwork

❄️ Turn off your system immediately if frozen – running it can cause compressor damage. Call (773) 915-6421 for same-day thaw service in .
