Why Isn’t My AC Cooling My Home?

Inefficient Cooling in Aitkin, MN

It can be frustrating when your AC system is running but not producing cool air. There are a number of reasons this occurs. Some of the cooling issues you can solve, but for others, you need the help of an experienced technician.

Thermostat Set to “ON”

Check your thermostat to see if the fan is set to “ON” or “AUTO.” When it’s set to “AUTO,” the fan will run regardless of whether or not the air conditioner is running. Set it to “ON,” so the fan only comes on when the air conditioner does.

Dirty Filter

A dirty filter impedes airflow through your air conditioning system. Your AC system can’t operate as it should and may even shut down after becoming overheated. You should check the filter monthly and replace it when you notice it’s dirty.

Obstructed Condenser

Your outdoor AC unit houses a large condenser. If the condenser becomes jammed, it may operate but not be able to extract enough heat energy from your home. Debris that can jam the condenser includes grass clipping, leaves, and dirt. Open your outdoor AC unit and gently hose the condenser down.

Broken Condenser Fan Motor

A broken condenser fan motor will cause your outdoor AC unit to malfunction and fail to dissipate heat. This means your air conditioner can’t cool your home. You’ll need a technician to fix or replace the motor.

Leaking Refrigerant

Your AC system uses refrigerant to transfer heat from your home to the outside. If there’s a refrigerant leak, your system can’t cool your home. You should turn off your AC system and call a technician to fix this problem and recharge the refrigerant.
