Troubleshooting Your South Florida Air Conditioner

Your air conditioner unit is an important asset to your home and to ensure the maximum life of your unit, regular maintenance should be done. There are a few signs that your unit may need maintenance, repair, or outright replacement. If you are unsure of any symptoms your unit is exhibiting, contact Cousin's Air, Inc. to schedule an appointment for AC service in South Florida to ensure that your home's air quality is kept in peak condition.

  • Blown Fuse: When your air conditioner stops working abruptly it can mean a blown fuse.
  • Freezing Up: If your air conditioner has ice on the coils and there is no air flow, it might be frozen.
  • Just Humming: If your air conditioner is just humming but it is not vibrating or cooling, the cause could be a bad transformer.
  • Just Shut Off: If your air conditioner just shuts off it could be a result of a thermostat malfunction, a tripped breaker, a float switch system, or a stolen condenser.
  • Keeps Turning On and Off: Some reasons for your air conditioner to turn on and off include an oversized air conditioner unit or a backed up drain line with a clog or blockage.
  • Leaking Water: Some causes for air conditioner leaks include a backed up drain line that might have a clog or a blockage, a cracked drain pan, or frozen coils.
  • Low on Freon: If your air conditioner unit keeps icing up, it might need refrigerant.
  • Making Noise: There could be a damaged balance blower wheel or condenser fan blade; it can also mean that the compressor is bad.
  • Mold: Causes of mold include water leaks, dirty filters, or an oversized unit.
  • Not Blowing Air: This can be a result of a possible bad breaker, the coils could be frozen, or you might have a bad fan motor.
  • Not Cooling: Possible causes include a problem with the thermostat setting, frozen coils, or a tripped float switch.
  • Not Working: There are numerous problems that can cause your AC unit to stop working but to best diagnose your issue, contact Cousin's Air, Inc..
  • Only Works on High: There could be an issue with the control board or the thermostat.
  • Overflow: This can be attributed to a possible blockage, dirty coils, or a cracked drain pan.
  • Bad Smell: A bad smell could mean that mold or mildew is present, something might be stuck in the duct work, or it could just be that you turned on the heater for the first time in a while.
  • Tripped Breaker: This can be a result of a few different problems including a shorted motor or a bad grounded compressor.
  • Vibrating: This usually means that there may be a part off balance, or something blocking a blower or a fan.
  • Won’t Turn Off: If your unit doesn’t shut off, it usually means that there is a problem with your thermostat, which alerts the unit that your home is adequately cooled and tells it to shut off.
  • Won’t Turn On: There are a wide variety of issues that can cause this problem, it is best to contact Cousin's Air, Inc. to evaluate your unit.
