Cooling tune up performed today on a one year old Lennox h at pump with air handler. 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. Highly suggest adding a whole home surge protector to the main panel to protect the home and the appliances in the event of a surge.
