Common AC Unit Repair Issues

When it comes to AC unit repair, there are several common issues that homeowners may encounter. Understanding these problems can help you identify when your AC unit needs attention.

1. Refrigerant Leaks

Refrigerant leaks are a common issue that can lead to decreased cooling efficiency. Signs of a refrigerant leak include warm air blowing from the vents, ice buildup on the coils, and hissing sounds coming from the unit.

2. Electrical Problems

Electrical issues such as faulty wiring or a malfunctioning capacitor can cause your AC unit to stop working. Signs of electrical problems include the unit not turning on, frequent circuit breaker trips, or strange odors coming from the unit.

3. Frozen Evaporator Coils

Frozen evaporator coils can restrict airflow and reduce cooling capacity. This issue is often caused by dirty air filters, low refrigerant levels, or a malfunctioning blower motor. Signs of frozen evaporator coils include reduced airflow, warm air blowing from the vents, and ice buildup on the coils.

4. Fan Problems

Issues with the fan can prevent proper airflow and cooling. Signs of fan problems include loud or unusual noises coming from the unit, weak airflow, or the unit not turning on at all.

5. Thermostat Malfunction

A malfunctioning thermostat can cause your AC unit to run erratically or not cool your home efficiently. Signs of a thermostat issue include temperature fluctuations, the unit running constantly, or the inability to reach the desired temperature.
