During the hottest days of summer, turning your air conditioner on only to be met with warm air, gurgling water or unsettling rattling is anything but cool. While complex mechanical repairs call for assistance from the pros, you can address some wall-unit woes with simple, universal troubleshooting measures, whether you have a through-the-wall unit, a window unit mounted in the wall or a split, ductless style AC.

Before making any moves, always consult the owner's manual. Ensure that your AC wall unit is securely plugged into an operational electrical outlet, if the unit's plug is visible. Check your circuit breaker for a blown fuse and replace the fuse if necessary. Replace the batteries in your AC unit's remote control, if it has one. Through-the-wall and ductless, split AC systems often include these accessories. Clear any items that may block airflow near the interior front side of the air conditioner, such as curtains, drapes, blinds or large furniture. Likewise, close any open windows or doors. Disable your unit's "quiet" or "super quiet" setting, if it has one. These settings reduce noise by reducing fan speed, which reduces cool air distribution. Power down your AC and remove the air filter, the mesh-like panel under the front grille of its interior side. In some through-the-wall and ductless systems, you may have to remove the front panel to access the filter. Wash the filter with warm, soapy water;

allow it to air-dry completely before reinstalling it. For optimal operation, clean your AC's air filter monthly. Remove the front panel of the AC and use a wet-dry shop vacuum with a brush attachment to gently vacuum the interior compartment of the machine, focusing on key components such as the evaporator coils and fan blades. As is the case with the air filter, clean components make for smooth AC operation. Inspect the intake and outlet grilles on either side of through-the-wall or split, ductless units for debris -- such as leaves or twigs -- and clear the debris by hand or with a vacuum. Sometimes a clogged condenser causes the AC to emit warm air; because condensers expel heat to the exterior of the building, a blockage means the warm air has nowhere to go but inside. If your split, ductless AC has a separate, box-like exterior unit, clear debris from the outlet grills on this unit.

So much for a warranty. Cannot rate this as I just got it and it is January so it is still in box when I get it installed and use it I will rate it, so disregard the one star rating.
