Common Issues We Fix
Recognizing the Problem?
We've Seen It Before.
Not Cooling
Unit running but room stays warm. Usually a failed compressor, low refrigerant, or dirty condenser coils.
Not Turning On
A completely dead unit may have a blown fuse, failed control board, or power supply issue we resolve on the spot.
Leaking Water
Water dripping inside or outside the unit is often a clogged drain, dirty filter, or improper installation angle.
Freezing Up
Ice forming on the unit points to a dirty filter, low refrigerant, or failed fan motor restricting airflow.
Loud or Unusual Noises
Rattling, buzzing, or grinding during operation often points to a loose fan blade, failing motor, or debris in the unit.
Not Cooling Enough
Unit running but not reaching set temperature. Usually an undersized unit, dirty coils, or failing compressor.
Remote or Controls Not Working
Unresponsive controls or remote points to a failed control board, sensor, or receiver we diagnose accurately.
Bad Smell
Musty or burning smells coming from the unit point to mold buildup, dirty filters, or an electrical fault.
Fan Not Working
Blower or condenser fan won’t run. Usually a failed fan motor, capacitor, or control board fault.
Simple. Transparent. Done Right.
