When your A/C fails on you, many air conditioner repair companies will charge you a fee to diagnose the problem. If you are familiar enough with your air conditioning system, you may be able to self-diagnose the issue and save on that cost altogether. This article discusses the different components of an AC system as well as common problems that you may experience. Of course, some problems are quite complex and will need an expert opinion.
Basic Components of Your A/C System
1. Compressor – A pump that is driven by an electric motor, it compresses low-pressure refrigerant gas into a high-pressure gas.
2. Condenser – A coil through which refrigerant gas flows while a fan blows air to cool the gas into a liquid.
3. Metering Device – a temperature control device that senses and dispenses liquid refrigerant into an evaporator coil.
4. Evaporating Coil/Cooling Coil – tubing through which the liquid refrigerant is controlled and evaporated. It will go from liquid to gas.
5. Air Handler and Blower Unit – provides a fan to blow air across the evaporating coil, while also taking away the moisture from the cooler air.
6. Controls – basic buttons and controls such as room thermostat, air filters, electrical switches, and circuit breakers.
Take a look at an AC diagram to help visualize how these components fit together.
Common A/C Problems
Problems with air conditioner systems are typically either mechanical or electrical. Mechanical issues include refrigerant leaks (usually identified by oil deposits on the line), piping damage due to corrosion or improper installation as the pipes were passed through the house wall, failed air handler, dirty or missing air filters, failed compressor or condenser, inability to dehumidify as it cools, or inability of the system to start due to failure of one or more of the components of the system.
Electrical problems are found during most A/C repair calls. A problem could be due to the circuit breaker itself, which should be reset in this case, or due to failure of one or more of the controls and features. Switches could become ineffective simply by a wiring problem or by becoming “stuck” and unable to move. A/C repair contractors may be able to solve your electrical issue due to the numerous cases they receive, or you may require an electrician.
