Common Air Conditioner Problems in the St. Louis Area
Air conditioners tend to be reliable systems, but even with proper maintenance, normal wear and aging will eventually problems. Some of the most common include:
- The system fails to turn on: This can be caused by a tripped breaker, a tripped pressure switch, or an overheated compressor, as well as incorrect thermostat settings, a failed start capacitor, or a damaged compressor.
- Poor cooling performance: The air filter may be clogged, there may be obstructions in the ducts or vents, or the refrigerant level may not be correct.
- Unusual noises: Tapping or thudding may indicate a damaged belt in the air handler. Whining or screaming may indicate a damaged compressor. Buzzing may indicate a damaged start capacitor or electrical problem.
- Strange smells: A burning smell or smoke may indicate an electrical problem. A musty odor may indicate moisture problems or mold growth.
- Frozen evaporator: This can be caused by clogged air filters, duct obstructions, dirty condenser, or incorrect refrigerant levels.
Some problems can be simply fixed by resetting the breakers, replacing the air filter, or correcting airflow problems like blocked vents or obstructed ducts. If the problem is more serious, it’s best to call an HVAC expert as soon as possible so that you can avoid further damage to your air conditioning system.
