Troubleshooting

residential air conditioning
  • Check the A/C filter. It must be changed no less than every month no matter what kind of filter you may have.
  • If the filter is very dirty, go outside and inspect the copper lines going to the condensing unit or look down into the condensing unit at the compressor. You will be looking for ice on the copper line going to the condensing unit and on the compressor.
  • If ice is present, the evaporator coil in the attic will be frozen, as well. Simply turning the system off will not work well because the evaporator coil is enclosed in an insulated casing and will take a very long time to thaw out completely.
  • If this is the case, go to the thermostat and switch the system from cool to the "Off" position. Next, switch the fan control on the thermostat to the "On" position, allowing the blower fan to run continuously. The air from the fan will thaw out the evaporator coil in approximately two hours. Also, as the ice begins to melt, it will deliver some cool air into your living space.
  • If the filter is not dirty and you have a digital thermostat, you may need to change the batteries. If the inside unit is working, but the outside unit is not, you should probably change the batteries.
  • If you have a manual thermostat and the outside unit will not come on, you should inspect the small brown thermostat wire going to the condensing unit. It can often be damaged by dogs or a weed-eater.
  • If the wire is damaged, it can be simply repaired or replaced. Turn the power to the unit off while this is being done.
  • If none of these steps alleviate the problem, you should contact the trained technicians of Action Air Conditioning.
