5 Common AC Problems

common problems for Kansas City Air conditioners:
1. Refrigerant Leaks

Refrigerant (also called Freon™ ) leaks are very common. If you suspect a leak, it’s important to have a trained technician find it and repair correctly before recharging the refrigerant. Leaked refrigerant harms the environment. Some signs your air conditioner has a leak include:

  • Warm or lukewarm air coming out of the supply registers.
  • It takes a long time to cool the house.
  • A hissing sound can alert you to a punctured refrigerant line either near the outside unit or inside your home.
2. Frozen evaporator coils

If you see ice on your evaporator coils, please turn off your unit to avoid damaging your compressor. While you’re waiting for the technician to arrive, change your thermostat from “cool” to “off”, but keep the fan blowing. Running the fan helps the coils thaw so your unit can be repaired faster. Frozen evaporator coils may signal:

  • Inadequate airflow. This could be caused by a dirty air filter, debris around the coils, or closed air supply vents, or blocked air registers in your home.
  • The thermostat is set too low. Air conditioning systems are designed to cool your home to 20° cooler than the outside air. If you set your thermostat much lower than that, it can strain your system and cause it to freeze up.
  • Blower motor failure. The blower motor keeps air flowing through your system. When it breaks, the coils can freeze.
  • Low refrigerant. The refrigerant allows the coils to absorb the heat in your home. When it’s low, the coils can’t hold heat and can drop below freezing.
3. Electronic control failures

Age or a lack of regular maintenance may cause electric control failures. When this happens, compressors, fans, and wiring can become overworked or fail. This usually means a part needs to be replaced and can mean either minor or major repairs.

5. Clogged Condensate Drains

Hot, humid weather often brings blocked condensate drains. When your evaporator coils cool the warm air from your home, humidity condenses around the coils and collects in your condensate drain. Leaks can cause problems, and sometimes dirt or algae block the line. Signs that you have an issue with your condensate line include:

  • Water around your furnace. When the condensate line is leaking or the pan is full, water will pool around your indoor unit.
  • Bad odors. A strong smell can be a sign that bacteria or algae growth may be blocking your condensate line.
  • System shut-off. Because leaks can cause property damage, many systems have a safety shut-off setting when it senses the condensate line is blocked.  If your system does not have one, A.B. May can install one.
