  Your Dantherm Air Conditioner might not be cooling well due to several reasons. The filter could be clogged and needs cleaning or replacing. The evaporator or condenser coil might be blocked and require cleaning. The evaporator or condenser blower may not be working, necessitating replacement of the motor, capacitor, or the entire assembly. There could be a refrigerant loss or oil leak that needs locating and repairing, followed by a recharge. Finally, the unit's capacity might be insufficient for the space; in this case, contact Dantherm, Inc.
