Why is my Trane Air Conditioner making noises?
- CChristopher KaiserJul 30, 2025
Your Trane Air Conditioner might be making noise due to several reasons: the electronic expansion valve initializing, gas refrigerant flowing, gas refrigerant starting or stopping, the drainage system operating, or unit panels expanding or contracting due to temperature change. If a malfunction is detected, immediately turn off the main power switch.
