Cooling tune up performed today on a two year old Lennox gas furnace with a straight cool condenser. All electrical connections are tight with no corrosion. ECM blower motor is acceptable. Blower wheel and evaporator coil are clean. Compressor and condenser fan motor are acceptable. Refrigerant levels are in range. Outdoor unit was washed and waxed. Suggest adding a compressor saver to the outside unit to help with the efficiency and reliability of the system upon start up.
