Problem Guide
AC Not Cooling or Blowing Warm Air?
Cooling problems can come from airflow, electrical controls, refrigerant-system faults, drainage issues, thermostat problems or failed equipment components.
What This Problem Can Mean
When an air conditioner runs without cooling the building, continuing to operate it may not solve the underlying problem. Tandem Mechanical can evaluate the equipment and system conditions to determine the cause and explain the appropriate repair options.
Warning Signs
Supply air feels warm
System runs continuously without reaching setpoint
Outdoor unit will not start
Indoor coil or refrigerant line is icing
Breaker trips when AC starts
Water is leaking around the indoor equipment
Possible Causes
Dirty or restricted airflow
Electrical or control failure
Refrigerant leak or refrigeration-system problem
Failed capacitor, motor or compressor component
Condensate drain or float-switch issue
Thermostat or sensor problem
What To Do Now
Confirm thermostat mode and setpoint
Check the air filter if it is safely accessible
Turn the system off if it is icing heavily or repeatedly tripping a breaker
Schedule professional diagnosis if normal cooling does not return
What Not To Do
Do not add refrigerant without locating the cause of a loss
Do not repeatedly reset a tripping breaker
Do not chip ice from a coil
Do not bypass condensate or electrical safeties
