Preventing Coil Freeze Up

There are some proactive steps you can take this fall to ensure your chilled water coils do not freeze up this winter. The first step is to make sure that the freeze stat on each of your air handlers has been tested in the last 60 days. If testing has not been done, you might want to check the freeze stats for proper operation. Typically, they should be set on 35 degrees F with the tubing on the leaving side of the chilled water coil. If you are not sure how to check your freeze stat, check with your controls contractor for assistance.
