Carrier HVAC Error Code 58: How to Fix It

Q: What does Carrier error code 58 mean?

It means the refrigerant temperature is too high, often due to low refrigerant, a dirty coil, restricted airflow, or a faulty compressor.

Q: Can I drive my car with error code 58?

This error is for HVAC systems, not vehicles. You should not operate the HVAC system until the issue is resolved to prevent damage.

Q: How much does it cost to fix Carrier error code 58?

Costs vary: cleaning coils may cost $50-$200; refrigerant recharge $150-$400; compressor replacement $1,500-$3,000. Contact a local technician for an estimate.

Q: Is it safe to reset Carrier error code 58?

You can reset the system by turning off power for 5 minutes, but if the underlying issue isn't fixed, the error will return. Resetting is a temporary measure.

Q: Do I need to replace the entire unit for error code 58?

Not necessarily. Many causes (dirty coil, low refrigerant) are repairable. However, if the compressor fails, replacement may be more cost-effective for older units.

Abstract

Carrier error code 58 indicates that the refrigerant temperature in your HVAC system is too high. This can be caused by low refrigerant, a dirty condenser coil, a faulty expansion valve, or a failing compressor. High refrigerant temperatures can lead to system damage and reduced cooling efficiency.
