Why HVAC Coils Freeze & How to Prevent Failure
Don’t Get Ruptured!
At temperatures 32°F and below, water can freeze and expand, causing excessive pressures that result in coil damage within a matter of minutes. Consequentially, expensive and time-consuming maintenance, coil repair, downtime, and potentially serious subsequent damage from the thaw and flood often occurs.
