Thoroughly performed a tune up for a 2014 Lennox split system, washed condenser coil out, checked heat pump components, dual run good, amps all within specs, evaporator coil is extremely dirty, filter needs to be a 20X25 and the blower cap is below specs. Recommended a Level 2 duct cleaning, UV system, coil cleaning with acid and a blower capacitor. Customer will talk to his wife and call back if they decide to do any recommendations.
