FAQ:

Q: What is a wet switch on an AC?

A: Here’s what it looks like installed inside the drain pan: Unlike a float switch, a wet switch contains a sensor that shuts down the AC when so much as a drop of water touches it. It helps you avoid problems like


Q: How does an AC float switch prevent water damage?

A: By preventing water damage in your home, your AC float switch can save you from making expensive repairs, not just to your AC unit but your home and furnishing. When there is an overflow in the AC drainpipe, the water that spills inside the unit normally encourages the growth of mold.

Q: What is the difference between a float switch and wet switch?

A: Unlike a float switch, a wet switch contains a sensor that shuts down the AC when so much as a drop of water touches it. Debris clogging the drain line coming from the pan – it shuts the system off before the pan fills up. Installation mishaps – it’s a lot harder to install the wet switch incorrectly.

Q: What is an AC drain pan and float switch?

A: Luckily, most HVAC companies install a drain pan and float switch to help you avoid these sorts of problems. If there’s a clog in the drain line, the AC leaks into the pan. A separate drain line from the pan channels the water to the proper place.
