Common signs include your AC unit humming but not starting, random system shutdowns, or a complete failure to turn on. Capacitors, which help start and run the motor, often fail during our hot summers when systems are under the most strain. If you notice these issues, it's best to call for a professional diagnosis to prevent further damage to the compressor.

Signs of a refrigerant leak include reduced cooling power, ice forming on the refrigerant lines or evaporator coil, and a noticeable hissing or bubbling sound from the unit. Leaks are problematic because they force your AC to work harder to cool your home, increasing energy bills and putting extra stress on the compressor, which can lead to a costly breakdown.

First, check your thermostat settings and circuit breaker to rule out simple issues. If those are fine, avoid repeatedly trying to restart the unit, as this can cause more damage. The most common culprits during heat waves are capacitor failures or refrigerant-related problems. For a safe and effective repair, contact a local HVAC professional like Integrity Air Systems for a prompt diagnosis.
