Window ac repair

There are a number of air conditioners in the market and one of these types of air conditioners is window air conditioners. Window air conditioners are installed in an open window in a particular room. Their components are tailored to a size that can fit a compact box and are thus known as unitary air conditioners. The air inside is cooled as a fan blows it over the evaporator which removes the heat from the air. On the exterior the heat drawn from the interior is expelled into the environment as a second fan blows outside air over the condenser. A large house or building requires several such units, for each room to be cooled separately. These units are most commonly found in hotels and apartments. They are quite similar to the other air conditioners that is the central air conditioner, the split system, the portable air conditioner and the car air conditioner. These air conditioners have similar major components such as the compressor, the condenser, the evaporator, the expansion valve and the drier or accumulator. These are the major parts involved in cooling a room in the case of a window AC. The refrigerant is the liquid used to ferry heat from one component to the other.

These window air conditioners have many options including the Portable air conditioners also known as PTAC systems. They differ from the window air conditioner because they are mobile and are usually placed on the floor and attached to a hose on the wall.

These systems which are most commonly used in hotels have two separate units, the evaporative unit on the inside of the room and the condensing unit on the outside with an opening passing through the wall and connecting them. This is so that anyone within their room can adjust the temperature settings. These PTAC systems may be adapted to provide heating in cold weather and this is done using an electric strip or by reversing the flow of refrigerant with the heat going to the interior and basically have the system operate like a heat pump.

Repair of window AC includes an initial check by the technician to make a diagnosis. The technician will do a visual inspection of the components, then he will do a performance test where he will turn on the unit and evaluate how well it works and whether it is working at all. He will also test the pressure using a PSI. If he sees that the system is not operating at all he will first check the switches to make sure it is not a faulty switch causing the problem. Then if that is not the problem he will open the unit and based on the pressure readings if they are too high he will know it is a clogged system or a valve that is jammed. If the system pressure is low it could be a leak of either air or refrigerant. He will be able to make the diagnosis and offer you the quotation of the bill and the repairs.
