Given that the main function of your air conditioner is to send cool air through your home, improving your indoor comfort during the spring and summer, it’s natural to assume that a little bit of icing on the unit is normal.
However, on the contrary, a frozen air conditioner can signal a big problem. If you notice ice on your equipment, first turn your system off so it can defrost. Before turning it back on though, it’s important to understand what could have caused this to happen, and get it repaired by a professional if necessary.
