Central air conditioning (A/C) systems are generally reliable if the proper maintenance procedures are performed at the recommended intervals, but they are not perfect. If the system in your Wichita home is having problems, try these A/C troubleshooting tips to rule out simple things you can fix yourself, before spending the money for a service visit:

  • System Will Not Start: Make sure that there is power going to the system. Check the breakers in your main service panel. Also check any safety switches, such as the high-pressure switch for the compressor, to make sure they have not been tripped. If there is power to the system, check your thermostat to make sure it is set correctly and has power. Replace the batteries on models that use them. Finally, make sure the condensate drain is clean and that there is no standing water. If these suggestions do not work, there may be a problem with the compressor, which will require the assistance of a professional.
  • Poor Cooling: Make sure the thermostat is functioning, and if it is, check the condition of the evaporator coils. If the coils are dirty, clean them gently with a vacuum and a soft-bristle brush, making sure not to bend any of the delicate fins. Also clean or replace the air filter. If cleaning the unit does not work, have the system inspected.
  • Ice on Refrigerant Lines: Shut the system down for a few hours. Restart it, and make sure that the large line going to the outdoor unit is cold, but not frosting over. If there is frost, have your contractor check the refrigerant level and pressure.
  • Condenser Cycling Frequently: Clean the condenser coils of leaves and other debris, and make sure the surrounding area is clear. Call your contractor if the problem persists.
  • Indoor Fan Not Running: Check the breakers for the air conditioner and the furnace, if the system shares the same blower. Have the fan motor checked if the fan does not start.
