Air Conditioning Troubleshooting

Try this:

• Find your breaker box and look for the circuit labeled “air conditioner”
• Try flipping that circuit to “off” and then “on”
• Give your air conditioner a couple minutes and see if it comes on now

Did that solve your problem?

Check your filter and change it if it’s visibly dirty.

Did that solve your problem?

Find the grey box generally affixed to your house that is wired in to the air conditioner outside.  Open the front door and check to see if the plug or the switch is set to the on position.

*Caution*  There will be high voltage to the disconnect.  This box is here so that we can kill power to the unit before it is worked on.  If you don’t feel comfortable checking this, please contact us for service.

Did that solve your problem?

• At the thermostat turn the fan to the on position and feel for air flow at the registers
• listen for the blower at the furnace itself.

Is the blower motor running in the furnace and attempting to move air?

Please turn off your system and get professional help.

Glad we were able to help you solve your problem. We’ll be here if you need us again.

If the refrigerant charge is off significantly it may cause the evaporator coil to freeze up during operation.  Once frozen it is difficult to push air through a block of ice and results in reduced air flow to the house.

Please turn the system “off” at the thermostat, but turn the fan to the “on” position.  The evaporator coil needs to be completely thawed out before we are able to diagnose and work on the system.  Turning the fan to the on position will make the furnace blow warm air from the house over the block of ice and thaw it out quickly.
