I am a highly skilled home service professional, and I recently completed a job that involved inspecting and servicing an air handler. The air handler was working great with no issues found. I inspected the unit's electrical connections, checked the refrigerant levels, and performed a thorough cleaning of the unit's components. I also tested the unit's airflow and temperature control to ensure it was operating correctly. I am proud to say that the air handler is now working great and the customer is satisfied with the service.
