4 Reasons Your Air Conditioner Won’t Shut Off

Inspect the Thermostat

Before you assume the worst: check to see if the thermostat is set to the right air conditioning temperature setting. If the thermostat is set to a cold standard that is far too low, then your air conditioner won’t shut off because it’ll be working constantly toward a temperature it can’t reach. Aim for a reading that’s at room temperature or slightly above that. Now, if the air conditioner still won’t turn off, you know it’s an issue.

Sanitize the Condenser

Condenser coils are essential within the AC system. They remove the heat from the air. If they get dirty, the layer of dirt or debris causes them to overwork themselves and operate inefficiently. This keeps the air conditioner from reaching the set cooling temperature and can prevent your system from shutting off. If your air conditioner won’t turn off, you will need to inspect your condenser coils and see if they need to be wiped down.

Continuous Maintenance

At the end of the day, the only way to avoid big, unexpected problems with your AC is to be proactive. This means scheduling regular air conditioning repair and tune-up services from the HVAC experts on our team. If your air conditioner won’t shut off, our technicians will resolve the problem by cleaning the condenser coils, replacing dirty air filters, and checking for electrical issues. If you’ve been noticing that the air conditioner won’t shut off: get professional help.

Inspect the Fan Limit Switch

The fan of your air conditioning unit turns on when instructed by the thermostat. But it can also do so as part of an independent air circulation process. This is made possible by the presence of a fan limit switch. The fan limit switch overrides any thermostat signal telling it to stop running so that it can keep going. If your air conditioner doesn’t turn off, check whether you need to switch the fan limit switch from manual to automatic.


4 Signs It’s Time To Perform an Air Conditioning Repair

Now that you know some of the reasons why an air conditioner won’t turn off, you can determine when it’s the right moment to connect with a Fenwick technician. Don’t wait until a repair job becomes a full breakdown. Check for these warning signs.

Ineffective Cooling

When the temperature rises, your air conditioner should be able to keep up. If your air conditioner won’t turn off and you notice warm air in your living space, this is a sign of an issue in your system. When your air conditioner can’t do its job, call us before you turn into a puddle.

High Bills

Your energy bill—even in the summertime—shouldn’t be outrageously high. If your air conditioner won’t turn off and you are receiving expensive utility bills, we suggest you stop overpaying and contact a certified contractor immediately. Save on your utilities each month by having us inspect and repair all the little inefficiencies in your system. They can add up.

Rapid Cycles

Short cycling occurs whenever your air conditioner turns on, runs for a short period, and then turns off again. This happens before the house even gets cooled down, over and over again. If your air conditioner is performing short cycles or won’t turn off, call a certified technician to inspect your system right away.

Strange Sounds

Even though your air conditioner isn’t necessarily ultra-quiet, it shouldn’t make a racket either. Rattling, banging, screeching, grinding, clanging, hissing, and other similar noises indicate that something is wrong internally. Try not to wait for help with this one. Turn off your AC and call us to be sure it’s safe.
