Professional Advice
Repair or Replace Your Freezer?
The "50% Rule"
We believe in honest service. If your freezer is over 10 years old and the repair cost exceeds 50% of a new unit's price, we often recommend replacement instead of repair.
When to Repair
- The unit is under 7 years old
- Repair cost is less than 30% of replacement cost
- The issue is a known "wear part" (seals, sensors, belts)
- You are happy with the unit's performance otherwise
When to Replace
- The unit is 10+ years old (15+ for Sub-Zero)
- The repair involves a major component (compressor, transmission)
- You have already repaired the same issue twice before
- Replacement offers significantly better energy efficiency
