Manufacturer Lennox Model # HS26-042-4P Serial # 5804E20182 Completed a preventative maintenance on a older Lennox system. The temperature split is 20 degrees! I changed the 16x25x1 customer supplied filter. Then I made sure the system is draining properly. Then I went outside and performed amperage readings on the condenser fan motor 1.15 amps I can not guarantee it will make it though the season. The compressor 3.8 amps. The capacitor and contactor are operating properly at this point. Customer paid for chud club membership
