No matter what kind of heating and cooling system you have in your house, you can save money and increase your comfort by properly maintaining and upgrading your equipment. Common problems with air conditioners result from faulty installation, poor service procedures, and inadequate air conditioning repairs. There are two common air conditioning problems: refrigerant leaks and compressor issues. If your air conditioner is low on refrigerant, either it was undercharged at installation or it leaks. If it leaks, simply adding refrigerant is not a solution. A trained technician is the best person to contact for this air conditioning repair. Remember that the performance and efficiency of your air conditioner is greatest when the refrigerant charge exactly matches the manufacturer’s specification, and is neither undercharged nor overcharged. Refrigerant leaks can also be harmful to the environment. Meanwhile, when you set the thermostat to a temperature below the room temperature, you should hear the outdoor compressor run and see the fan turning inside the top. If the fan isn’t turning it is time for another air conditioning repair miracle. If you are able look for an overload button or switch to reset (not all types have this). Stick a screwdriver down through the top grille and try to spin the fan blades clockwise. They should spin freely. If doing this gives the fan enough of a boost to get going, the unit has a faulty capacitor that must be replaced by an air conditioning repair technician. Sensors are usually the last part that gives up, and when it does, professional help is immediately needed. However, there are things you can do to keep this system at shape. Room air conditioners feature a thermostat sensor, located behind the control panel, which measures the temperature of air coming into the evaporative coil. If the sensor is knocked out of position, the air conditioner could cycle constantly or behave erratically. You need to have your AC working. Do what you can to make it work when you have issues, but don’t hesitate to call an air conditioning repair professional.
