My AC Is Running but Not Cooling the House – What Now?

The last thing you want to happen in the sweltering heat of summer is an air conditioning (AC) unit running but not cooling your home properly. Don’t sweat it. Instead, try to find out what the problem is and possible solutions. The issue can be mechanical, electrical, or something as simple as dirty air filters. Since AC systems are complex, you should consider getting help from an AC repair specialist in Birmingham or elsewhere.

Reasons Your AC Is Not Cooling

Many things can go wrong with your unit and prevent cool air from circulating even when the AC is ON. Here are some common culprits:

  • A tripped circuit breaker
  • Clogged or dirty air filters
  • Opened windows or closed vents
  • Iced or dirty evaporator coil
  • Low or leaking refrigerant (Freon)
  • Holes or cracks in the ductwork
  • Clogged AC condenser (outside unit)
  • Lack of maintenance
  • Problems with your thermostat or wrong thermostat setting
  • Problems with the AC capacitor or compressor contactor, blower motor, or condenser fan motor

What To Do If Your AC Isn’t Cooling

Closing windows and doors, opening all vents and clearing any blockage, and resetting the tripped circuit breaker are some quick solutions. Here are some other easy fixes to get the cool air flowing throughout your home:

Thermostat: Sometimes, all you need to do is check your thermostat settings to see if it is on the HEAT or the wrong setting. Switch it to COOL, select “AUTOMATIC, instead of “FAN,” and then set the thermostat below room temperature.

Replace filters: AC experts recommend replacing your filters every 45 to 90 days. Your filters might be dirty or clogged and affect airflow if the last replacement was longer than 90 days ago.

Clean the compressor area: Increase airflow into your home by clearing away dry leaves, vines, and debris piled up next to the outdoor compressor unit. Also, remove any other obstructions.

When to Call a Professional AC Technician

Some of these problems, like changing the thermostat setting, are easy fixes. Other issues or major problems such as electrical or compressor failure may require an AC specialist to carry out maintenance or repairs. For example, federal regulations say Freon (refrigerant) may only be handled by a licensed HVAC professional. Your technician may perform these other HVAC services to restore cool airflow and have your system running efficiently:

  • Clean out the condenser, evaporator, filters, and coil
  • Seal holes or cracks in the ductwork
  • Fix loose or damaged wiring
  • Refill or replace the AC refrigerant
  • Fix problems with the breakers or fuses
  • Replace a failed or broken thermostat
  • Repair and lubricate the compressor parts and fix electrical problems, such as with the compressor fan
