During winter operation, it is normal for frost, and even ice to develop on a heat pump system. Heat pumps have "defrost" controls to address ice buildup and help insure efficient operation. 

Year round, dirt and debris can also affect system performance and efficiency of your cooling AND air conditioner systems. Therefore, Lennox recommends that, at the beginning of each heating and cooling season, the system should be serviced by a qualified HVAC professional. While this service generally includes a check of all major system components and equipment operation, it allows the technician to identify and address any concerns, should they exist, thereby helping to prevent more costly repairs, should those concerns be left uncorrected.
