Lennox Cooling Systems

Can frost, ice, dirt or other debris keep the outdoor unit of my cooling system from operating effectively?

It is normal for a heat pump system to develop frost, and even ice, during winter operation. Heat pumps have "defrost" controls to address ice buildup and help insure efficient operation. Dirt and debris can affect system performance and efficiency. 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.
