Common signs include reduced airflow from your vents, unusual noises like rattling or humming from the indoor unit, the system frequently short-cycling, or ice forming on the evaporator coils. These issues often stem from a failing blower motor, a dirty blower wheel, or blocked drainage. We'll inspect your air handler thoroughly to pinpoint and fix the problem.
