Air conditioning systems can develop a variety of issues that require professional attention. Understanding common problems and their costs can help you budget effectively.
Common AC Problems
- Refrigerant Leaks: This often results in inadequate cooling and may require system recharging or repair of the leak.
- Thermostat Issues: A faulty thermostat can lead to incorrect temperature readings and inefficient cooling.
- Clogged Filters: Dirty air filters reduce airflow and efficiency, resulting in higher energy bills.
- Electrical Failures: Problems with the electrical components can prevent the system from starting up or running properly.
- Drainage Problems: A blocked drain line can lead to water damage and affect the performance of the AC.
- Compressor Issues: A malfunctioning compressor can render the entire system useless and may be costly to replace.
