How Do You Troubleshoot a Trane AC Unit?

To troubleshoot a Trane AC unit, you must first identify the specific problem. Common problems with Trane AC units include incorrect thermostat settings, lack of airflow, frozen oil and tripped circuit breakers. Setting the thermostat is necessary before running any controllers in your home. Before considering that the problem is a clogged indoor filter, check your coil system to see if it is frozen or dirty.

If your Trane AC unit lacks airflow, start by checking the system filters. Most Trane AC units are designed for vacuuming or cleaning. The filter also allows easy slide-out cleaning. Check and clear the clogged filter to allow more airflow.

If there is water under the unit and a cold exterior surface on the enclosures of the coil, shut down the system thermostat for a few hours. In some cases, the system requires the unit to defrost and restart to fix a frozen coil.

If the heating system comes to a complete halt, begin by checking the A/C, HP or air handler circuit breakers. Modern machines can fail as a result of overloaded circuits and older wiring. It is necessary to check and reset your circuit breaker in the event your system fails completely. If the system fails because of a faulty home breaker box, it is necessary to contact professionals for assistance.
