- AC won’t turn on. If it’s hot and humid outside, you need your AC to work properly. If your AC wont’ turn on, then there can be numerous things wrong with its operation. First, check to make sure that it hasn’t blown a fuse or tripped the circuit breaker. You should also ensure that the thermostat is set for cooling and its setpoint is lower than the current indoor air temperature. If neither of those quick fixes works, then you may have an electrical problem in the supply line, or a bad capacitor.
- Hissing sound. If you hear a hissing sound in or around the coils or refrigerant piping, then you may have a refrigerant leak. Even the smallest puncture can allow gaseous refrigerant to leak into the outdoor air. This can dramatically reduce your cooling performance and efficiency over time.
- Frozen evaporator coil. While the sight of frost may be a welcome sight for Fresno residents on a summer afternoon, a frozen evaporator coil is typically related to an airflow problem. Check your air filter to make sure it’s not dirty or clogged with dust and debris. When your coil freezes, it will not be able to cool the air brought into the air handler by the blower, and this can result in various problems, such as inadequate cooling in your home and an overheated compressor.
