Why Is My AC Running but Not Cooling My House in Mobile, AL?

If your AC is running but not cooling in Mobile, AL, you’re definitely going to notice it during our hot and humid Gulf Coast summers. Sometimes the cause is something simple, like a dirty air filter or incorrect thermostat setting. Other times, an AC that runs but doesn’t cool can be a sign that your system needs professional attention. Here are six common reasons your air conditioner may be running without keeping your home comfortable.

1. Your Air Filter May Be Dirty

One of the first things to check when your AC is running but not cooling is the air filter. A dirty or clogged filter can restrict airflow through your system, making it harder for your air conditioner to keep your home comfortable. With the heat and humidity we experience along the Gulf Coast, your AC may run for long periods during the summer, so checking your filter regularly is especially important. If the filter looks dirty, replace it with the correct size and see if your airflow improves. The U.S. Department of Energy also recommends regularly replacing or cleaning air filters because dirty filters can reduce airflow and system efficiency.

2. Check Your Thermostat Settings

Before assuming something is wrong with your AC system, take a quick look at your thermostat. Make sure it is set to “Cool” and that the temperature is set lower than the current temperature inside your home. If your thermostat uses batteries, weak batteries can sometimes cause problems too. You can also check that the fan setting is on “Auto” rather than “On.” When the fan is set to “On,” it may continue blowing air even when your air conditioner is not actively cooling.

3. Your Outdoor AC Unit May Not Be Cooling Properly

Your outdoor AC unit needs plenty of airflow to release heat from your home. Grass clippings, leaves, dirt and other debris can collect around the unit and make it harder for your system to work properly. Take a look outside and make sure there is nothing blocking the unit. You can remove loose leaves or debris around it, but avoid taking the unit apart or attempting electrical repairs yourself.

4. Your Evaporator Coil May Be Frozen

If your AC is running but you’re getting little or no cool air from the vents, your evaporator coil may be frozen. You might notice ice on the refrigerant lines or around parts of the indoor unit. Restricted airflow, a dirty filter or a refrigerant problem can all contribute to a frozen coil. If you see ice, turn the cooling system off and allow it to thaw. If the problem returns, it’s a good idea to have an HVAC technician find out what is causing the coil to freeze rather than continuing to run the system.

5. Your AC Could Be Low on Refrigerant

Refrigerant plays an important role in removing heat from your home. If your AC system is low on refrigerant, you may notice that it runs for long periods without cooling properly, blows warmer air from the vents or develops ice on the refrigerant lines. Because an air conditioner is a closed system, low refrigerant can be a sign of a leak or another problem that needs to be diagnosed. Refrigerant issues should be handled by a qualified HVAC technician who can determine the cause and recommend the proper repair.

6. There May Be a Problem With an AC Component

Sometimes an air conditioner can be running even though an important component isn’t working properly. Problems with a capacitor, contactor, condenser fan, compressor or other electrical component can prevent your system from cooling the way it should. These problems can be difficult to diagnose without the proper tools and training. If you’ve checked the simple things like your thermostat, air filter and outdoor unit and your home still isn’t cooling, it may be time to have the system professionally inspected.

When Your AC Is Running but Not Cooling, Should You Call an HVAC Technician?

If your AC is running but your Mobile home still isn’t cooling, you don’t have to wait until the system completely stops working to have it checked. Strange noises, weak airflow, warm air, ice on the system or an AC that seems to run constantly can all be signs that something needs attention. Having the problem diagnosed early may help prevent a small issue from turning into a more expensive repair.
