What are some signs of a failing AC unit?
If you aren’t getting consistent, cool air throughout your home, then your AC unit may be inefficient or broken. Keep an eye out for the following signs that your unit requires attention:
Refrigerant leaks: Your AC unit relies on refrigerant to cool the air that is forced through your home. The refrigerant runs through the coils of your AC unit, as well as the compressor, where it changes from liquid to gas, which provides the cooling effect. If your line springs a leak, you’ll lose refrigerant which will affect the performance of your AC unit, eventually rendering it ineffective. Larger leaks may cause your AC unit to quit completely, right away.
Compressor failure: Your compressor converts gaseous refrigerant back into a liquid, making it essential for the function of your AC unit. If you have an issue with the compressor, your cooling system won’t work. Often, we recommend completely upgrading the AC system if you have an issue with your compressor. Compressors are difficult and expensive to replace, so it’s likely worth it to invest in a new unit.
Frozen evaporator coil: Your evaporator coil absorbs heat from the air around it, and it may collect frost if it is overused. If you have an AC unit that is constantly running, or the air isn’t being forced from the AC unit to your home, then your evaporator coil may freeze. While your air conditioner may still function, you should turn off your AC to prevent further damage that can occur. Let your evaporator coil defrost and dry before turning on the AC.
Faulty electronics: Your cooling system is outfitted with a variety of electronic components. From the motor to the compressor to the thermometer wiring, these components can fail, which can bring your cooling system to a halt. If your AC unit quits on you, you may have an issue with any one of these components — we’ll take a look and pinpoint the problem.
Drainage issues: Your AC unit may collect condensation as it operates. While that’s normal, you may end up with a drain pan that overflows, especially if there is a blockage. You should be wary of excess condensation and water buildup around your cooling system.
AC motor inefficiency or breakdown: The motor that operates the condensing fan of your AC unit is liable to fail, especially since this component is exposed to the elements. We recommend regular maintenance to ensure that your AC motor runs smoothly throughout its lifetime. If you are experiencing a problem with the motor, your motor may need oil, it may need a new belt, or it may have an electrical problem. Again, we can assess the situation at hand and pinpoint the problem.
Thermostat problems: Your thermostat should trigger your AC unit to come on at the right time. However, if you have a thermostat that is poorly calibrated or the electrical components fail, then your unit may not turn on at the right time or at all.
