Heating and air conditioning can be a big mystery, especially when something goes wrong. What happens if your A/C fan is always running? Here are some troubleshooting tips you can use if this happens to you:
There are two things to check on your thermostat if your air conditioner fan runs continuously.
First, check the temperature setting. If it’s set too low the A/C might not be able to keep up with demand. Turn the temperature setting higher than the room temperature. If the fan shuts off, that was the problem.
Second, check the fan switch. If it’s set to “on,” switch it to “auto” or “off” and see if the fan shuts off. If not, it’s not the fan switch.
Take a look at the blower on your cooling system. There should be a fan limit switch. If the switch is set to “manual,” it means the blower will run constantly. You want to switch it to “auto.” This allows the thermostat to control when the blower turns on and off based on demand.
If neither of these tips turn the air conditioner fan off, it might be time for a service call. A licensed technician can evaluate the situation and determine what could be the cause. If repairs are needed, they can do them while they are there.
If your air conditioner fan won’t turn off and you’ve done some troubleshooting, the next step is to call All City Heat and Air for a heating and air conditioning service call by contacting us or calling 704-545-2000.
It turned out that our painting contractor put a nail through one of the AC lines in our walls and caused a Puron leak. Ernie was able to find the leak and fixed our problem at no charge to us even though it was not his fault and it took him considerable time and effort. His persistence and patience were amazing. This was the most impressive contractor experience that I have ever had.read more
