Do not open electrical covers, touch refrigerant lines or bypass safety switches. For water leaks, protect nearby belongings and turn the system off if it is unsafe to run.
What a Provider May Investigate
Depending on the symptom, a technician may inspect airflow, controls, condensate drainage, wiring, sensors or system performance. Ask for a clear explanation of findings and the recommended remedy.
