Performed two system air conditioner tune up. Both systems run upon arrival, checked capacitors, contactors, electrical connections, refrigerant levels and amperage draw on compressors, condenser fan motors and blowers. Both systems are over 30 years old. Systems are worn out but still functioning, due to condition, age and efficiency I do not recommend any repairs be made and only recommend replacement.

Performing diagnostic service on 1981 General Electric Furnace and 1993 Trane condenser, system not functional on arrival. Water has been draining from coil into furnace, there is about 1/2” of water sitting in the burner compartment and at least one electrical connection is under water. Client experiencing burning plastic smell when system kicks on, likely coming from blower motor or gas valve, both of which have water damage. Preparing estimate to replace system and ductwork.

Performed tune up on 12 year old York air conditioner. Unit not cooling the house on hot days. High energy bills. Unit needed a coil clean and some refrigerant. Also noticed that a capacitor needed to be change and added a hard start kit to reduce starting amps and save some money. Clients home now cools properly and is happy, joined maintenance program as well.

Performed diagnostic on system. Nothing operating upon arrival, found fuse failed. Replaced with new and tested system, found blower motor pulling high amps on start up which caused fuse to fail. Full system is 17 years old, if blower is not replaced fuse may continue to fail. Due to age and efficiency recommend upgrading system. Declined other repairs, system is operating upon completion
