In the last two blogs, here and here, we talked about what you can do on your own when you are having issues with your air conditioning unit. So far we have only talked about what to do when you have having issues with the air blowing or not cooling at all. Today, we want to talk about what you can do when the whole unit is not working. When this happens, we tend to think the worst; that we will have to pay to get an all new unit. This may not always be the case. Troubleshooting Your Air Conditioning.
1. Check the electrical panel
It could be something as simple as a tripped breaker or a blown fuse that could be the issue.
2. Is the furnace switch on?
Maybe the furnace switch was turned off or the outside condenser power switch was turned off.
3. Turn off the power
Shut the power off to the unit and check the thermostat. You might need to replace the batteries in the thermostat. Wait a few minutes then try the system again.
4. Technical troubleshooting
If nothing has worked and you are up for it, you can open up the thermostat again and unscrew the wire to the Y terminal and touch it to the R terminal with the power on. If it works, you have a faulty thermostat. If it doesn’t, call a technician.
After trying all of these steps and finding that nothing is working, please call a heating and air conditioning technician at Alltech Air Conditioning.
