Why Is My Air Conditioner Freezing Up? Causes & Fixes — Scarborough Guide

Why Your AC Coil Freezes

  • Low refrigerant charge — Most common cause. Low refrigerant drops coil temperature below freezing. Repair: leak detection + recharge $400–$800.
  • Dirty evaporator coil — Dirt insulates coil, preventing heat absorption. Coil freezes. Repair: coil cleaning $250–$400.
  • Blocked airflow — Clogged filter, closed vents, dirty blower. Fix: replace filter, open all vents.
  • Blower motor failure — No airflow across coil; coil drops below 0C. Repair: $300–$600.

What to Do When AC Freezes

  1. Turn off the AC immediately (running frozen AC damages compressor)
  2. Set fan to ON only (no cooling) to thaw coil
  3. Replace filter while thawing
  4. After 2–4 hours, restart. If it freezes again: call a professional
