Check and replace dirty air filters, and ensure vents are not blocked. If the problem persists, our technicians are trained to diagnose the root cause—whether it's a refrigerant leak, a failing blower motor, or a faulty thermostat—and perform the necessary repair to restore efficient cooling and prevent future freeze-ups.
