Intro

When your AC is not cooling your house, it can be frustrating, especially during hot Memphis summers. This problem is very common in Tennessee homes. Many causes are simple, but others need professional tools.

What This Problem Means

An air conditioner removes heat from inside your home. If your AC is not cooling, heat is not being removed the right way. This can be caused by airflow problems, system issues, or worn parts.

Homeowners may call this:

• AC not working

• AC blowing warm air

• House not getting cool

Common Causes

• Dirty air filter blocking airflow

• Thermostat set wrong

• Low refrigerant (also called Freon)

• Frozen indoor coil

• Failed AC part

• Poor airflow from vents

In the Memphis area, high heat and humidity can make these problems show up faster.

Safe Things a Homeowner Can Check

Homeowners can safely check these items if they feel comfortable:

• Make sure the thermostat is set to cool

• Replace the air filter if it looks dirty

• Make sure vents are open and not blocked

• Check thermostat batteries

If you are not comfortable doing these checks, it is best to call a professional.

When to Call a Professional

You should call a licensed HVAC professional if:

• Air is still warm

• Cooling does not improve

• Ice forms on the system

• The system shuts off

Refrigerant and electrical parts are dangerous and should not be handled by homeowners.
