Diagnosing Your Malfunctioning Air Conditioner
There are three primary reasons why your air conditioner is blowing warm air, which are issues with the thermostat settings, ice accumulation on the evaporator, and airflow restrictions somewhere in the forced-air system.
The thermostat is the first thing you should check when you’re having air conditioner problems because the issue could stem from incorrect thermostat settings or loose or damaged thermostat components.
- Make sure the thermostat is in “cool” and “auto” modes. Set the thermostat temperature 5 degrees below room temperature. Your air conditioner should engage if this was indeed the issue.
- Remove the thermostat cover. Check for loose wires, and tighten the screw terminals as necessary. Use a soft cloth to gently clean the thermostat components and replace the cover.
Ice accumulation is a common issue for air conditioning systems blowing warm air. Ice on the evaporator coil prevents the refrigerant from extracting heat from the ducted airflow, which means the warm return air isn’t cooled before it recirculates into the living spaces. These are some of the causes and conditions which lead to ice accumulation:
- Dirty air filters – after you’ve given your air conditioner time to defrost, change the air filter and start it back up. If it functions properly, than this was your problem—simple as that.
- Refrigerant charge – this must be at optimal levels for efficient heat exchange. Too much or too little refrigerant stresses the coils and compressor and causes ice accumulation. Since refrigerant is a closed system, if you have an inadequate charge it means you have a leak or it was installed incorrectly—that means you need the help of a professional technician.
- Faulty electrical components – these can also stress your air conditioning system and lead to ice accumulation on the evaporator. This air conditioner repair issue, like refrigerant charge, should be handled by a trained professional.
If your problem is due to airflow restrictions you may simply need to walk through your home and inspect the registers and vents, clearing away any obstructions. You’ll also want to clear any debris or items that have gathered around your outdoor unit. In order to operate properly, your air conditioner needs a two foot radius around it of clear space.
