A Problem With The Ducts, Refrigerant, Fan, Or Coil Could Keep Your AC From Cooling Your Home
When your AC isn't working properly, you'll probably notice your home isn't as cool as it should be. However, it can be confusing if the blower and condenser still seem to be running. Your AC doesn't have to shut all the way down for it to malfunction and be unable to cool your house. Here are some possible reasons that your air conditioner is running but not keeping you cool – and the AC repairs that can help.
The Ducts Leak
If the air coming out of your AC is cold and the fan sounds like it's running as it should, the problem might be leaky ducts. When ducts leak, cooled air is lost to the attic. This keeps your home from cooling down, and that might cause your electric bill to get higher. It might be difficult to find a leak in a duct, but your AC repair technician can use a smoke pen or other methods to find the leak and patch it so cooled air is no longer being lost in your attic.
A Refrigerant Coil Is Coated in Ice
If the refrigerant coil in your air conditioner gets covered in ice, the AC won't be able to cool down your house. If the ice builds up enough, your AC will probably shut down and stop working completely. Ice can build up on a coil if the coil is dirty. The AC repair technician may need to clean the coil off to get rid of dust and grime buildup and see if that keeps ice from forming again.
A Fan Isn't Working Very Well
Your AC has two fans. One is in the condenser and helps move heat away from the AC. The other is in the air handler and blows air through the ducts. Both fans have to work optimally to keep your home cool. Sometimes the fans don't work because they get dirty. Other times, the fan blades might be loose due to constant vibrations in the AC. A part like the capacitor could go bad and affect how well a fan works.
The AC repair technician has to figure out why the fan isn't working at full capacity and then fix the problem so your AC is able to put out cool air at full force again.
The Refrigerant Is Low
When the refrigerant in your AC gets low, your equipment runs but it can't cool down your house. An AC repair technician can test the refrigerant line to see if it is low on refrigerant. Refrigerant doesn't drop unless there's a leak, so the AC repair technician might need to repair a tiny hole or tighten a loose connection to stop the leak. Once that's done, the refrigerant can be filled so your AC cools down your house again.
