OF stands for Overflow in HVAC systems.

Why is my AC overflow pipe dripping?

A clogged condensate drain pipe can make your AC system's drain pan overflow. This is probably the most frequent cause of water leakage from a central AC system, bringing many service calls to HVAC professionals as summer temperatures rise. Drain lines can become clogged with dirt, rust, algae and other debris.

How Do I Keep My A/C From Overflowing?

Most people don’t know that dripping is an indicator of a problem, they just think because it is hot the Air Conditioning is producing condensation. Without anywhere to escape this water will build up and should collect in the overflow pan.  But if you keep your Air Conditioner running, then more and more water is being produced with no means of escape.  The result is water overflowing into your home. Some form of overflow protection is important for your Home Comfort System.

There are two types of overflow protection in Residential HVAC

  • Wet Switch (AC float switch)
    The switch is activated when the level of the water in the pan comes above a certain point, causing the switch mechanism to trip/float to rise. When this happens, the switch will then send a message to the AC unit, and it will shut off, stopping the phase conversion and creation of condensation.
     
  • EZ Trap

We recommend installing both types of protection, so that if one fails the other is in place to protect you.
Have one of our technicians evaluate your system when they perform your annual tune up.
