Last month I talked about some simple maintenance tips and things to watch for to keep your air conditioning unit in good shape. Today we are talking about frost building up
If you left the freezer door open but put a fan and blow air in and out would it frost up the same? probably not. The airflow across the cooling coils stops the frost from building up. It’s the same with your airconditioning. Low airflow across the coils can cause them to freeze up. There can be other reasons for frost to build up, but sometimes its as easy as checking your furnace filter.
warm air is less dense and needs less of a push to flow through all of the ductwork. In the cooling season, the cold dense air needs a little more help to flow.
So we turn the furnace up to high speed to get that air to flow. The cooling coils inside the furnace need airflow to help keep them from freezing up as we talked about how the freezer with the door left open and no airflow will ice up, but if you put a fan and move the air across the coils it won’t.
Keep checking back I will be posting about why I think humidifies are a bad idea and cause more problems than solutions in the near future.
