Performing diagnostic service on one of three heat pump systems. One is currently not cooling a portion of the horse ranch, making it unbearable in this summer heat. Diagnosed failed low voltage fuse and repaired, system is now up and running and cooling the home. Clients can now stop melting and start enjoying their air conditioning!

Maintenance on 21 year old Tempstar R22 air conditioner, found dual run capacitor out of spec and compressor amperage on start up above manufacturers max allowed. Contactor is very burnt and pitted from years of use. Evaporator coil is full of rust, blower motor is using more power than manufacturer design. Two story house recommend zoning to have separate controls for upstairs and downstairs. Due to age, efficiency, condition and cost of repairs recommend upgrading system
