Trane Ac is the Best
I bought a new house (1800 sq feet) 16 years ago and a Trane AC was installed by the builder. The only problems I have had to this day is a disconnected wire in the condenser units, a small loss of refrigerant and a Honeywell mercury thermostat that needs calibration. That's it!!!! Is it still running? YOU BET IT IS!!!
Now that I am about to complete an one year course in HVACR at a technical school, I have started cleaning the evaporator coil, blower fan and return air duct on my unit. I just replaced the blower fan capacitor (getting 7 microfarads instead of 10). I intend to get another 10 years or more out of this central air conditioner.
YOU CANNOT STOP A TRANE!!!!
