Is your air conditioner freezing up? Are you finding a frost buildup on your refrigerant lines? Have you noticed that very little air is making it through your vents? There can be many reasons why your AC is freezing up. Nevertheless, your unit requires good airflow for it to work properly. Consequently, the coils could start to freeze before the condensed water gets the chance to drain away.
That said, it is important to address the problem quickly. A frozen air conditioner does not only cause a problem with cooling your home, but it can also cause severe damage to the unit. However, before doing anything else, go to your thermostat, turning your air conditioner off and switching your fan to “on”. This will help the ice to thaw.
An AC unit is supposed to pull your indoor air over the coils, causing any moisture to evaporate before it can freeze. Anything that restricts, blocks or otherwise stops the airflow will cause the coils to become overly cold. The condensation will not evaporate and freezing will start quickly. There are a few things that you can check before calling for an air conditioning repair person. Look to see if the air filter is dirty, the vents are closed, and if curtains or furniture are blocking the returns.
Beyond these few simple fixes, you should call for a professional air conditioning repair. You can have problems with your ductwork, blower motor, or evaporator coil. There is also the possibility of a refrigerant leak. If making sure the vents are open and clean doesn’t resolve the issue, you will need professional help
