North Chicago AC Repair Specialists
If your home’s AC suddenly won’t turn on, it obviously needs professional attention. However, myriad other signs of trouble typically precede a total failure.
One of the most common signs of a problem is when your AC stops blowing the frigid air it once did. If you’re keeping up with your AC’s annual maintenance needs, that shouldn’t happen. It may indicate a leak in the AC’s refrigerant lines that’s sapping its cooling capacity. When a small leak worsens, it may lead to frozen evaporator coils. Frozen coils will interrupt airflow to your home’s vents and may lead to your AC short cycling. If you ignore the problem long enough, you risk damage to your AC’s compressor.
Another common AC problem is a capacitor failure. A capacitor functions like a battery, which boosts your outdoor unit’s fan upon activation. Without it, your condenser fan may fail to turn on or run slowly. In either case, your AC won’t blow cold air.
In some cases, a failed or failing capacitor will emit a buzzing sound. If you hear that from your outdoor unit, turn off your AC and call for an AC repair service appointment. Replacing a failed capacitor is a simple job for a professional HVAC technician. You should never try to do it yourself, however, as you’d risk electrocution.
