Heat Pump Defrost Issues Repair
Outdoor unit frozen solid? Defrost cycle not working? We specialize in cold-climate heat pump defrost problems across Vancouver's winter conditions.
Understanding Defrost Cycle Problems
Heat pumps collect ice on the outdoor unit during cold weather. The defrost cycle reverses operation to melt this ice. When defrost fails, ice builds up and blocks airflow, causing system failure.
Common Defrost Problems We Fix
- •Defrost cycle never initiates - sensor or control board failure
- •Reversing valve stuck - won't switch to defrost mode
- •Defrost termination issues - runs too long or too short
- •Outdoor temperature sensor failure - incorrect cycle timing
- •Low refrigerant preventing effective defrost
Don't Try These Common "Fixes"
- ❌ Pouring hot water on the unit - can crack coils
- ❌ Chipping ice off manually - damages fins and coils
- ❌ Running system continuously to "burn off" ice - causes more damage
- ❌ Covering outdoor unit - restricts airflow and worsens problem
- ✅ Call professionals who understand cold-climate heat pumps
