Is your air conditioner constantly running? Does it fail to turn off, even when your home has reached your desired temperature? For many home owners, AC that won’t turn off is just as problematic as one that won’t turn on. If you find that your air conditioner keeps running instead of shutting off, there are a number of reasons why this may be occurring. Follow these DIY troubleshooting steps to try in order to identify the cause of the problem:
Start with the thermostat.
A defective thermostat or improper setting can result in your AC not shutting off. Confirm that your thermostat is not the cause of the problem by turning the temperature up a few degrees. If this does not shut off your air conditioner, proceed to further troubleshooting steps.
Change the air filter.
If your filter hasn’t been changed in a while, it is likely full of dust and debris that restricts air flow. When air flow is compromised, your air conditioner does not have enough air flowing over its coils. This means the system cannot remove humidity and cool the air, making it run constantly.
Determine if the evaporator coil is frozen.
Is your air conditioner blowing warm air but won’t shut off? You may have a frozen evaporator coil. Your best bet is to shut the system down completely to prevent further damage, and call an air conditioner repair specialist to diagnose the issue.
Get a pro to check your refrigerant levels.
You may have low refrigerant levels in your air conditioner, causing it to run continuously. Never attempt any repairs relating to the refrigerant in your unit. Always call a professional who can examine your equipment and top up refrigerant safely.
Consider whether your unit is properly sized.
If your AC won’t turn off and it is a brand new unit, or it is your first time using it, the equipment may actually be incorrectly sized for the needs of your home. If it is under-sized, it may run constantly, trying to cool your home to your desired temperature. Contact a pro if you think this might be the case.
