A:Answer An air conditioner may not cool properly due to restricted airflow, incorrect temperature settings, a dirty filter, a hot starting room, cold air escaping, or iced‑up cooling coils. For ways to troubleshoot this issue, see the “Air conditioner does not cool as it should” section on page 13 of the Owner’s Manual, which can be viewed at the bottom of the Features tab on the product page of the Best Buy website. -- If those tips don’t help, see page 17 of the Owner’s Manual for warranty exchange information.
