A heat pump air handler in the attic needs a drain pan and a float safety switch, or a clogged drain can soak the ceiling below. On this attic replacement, both went in new.

Tyler Griffin, SwiftPro's owner, climbs into an attic to check on the install, appearing by face cam over the work. It's close to 100 degrees up there, a jobsite fan running, the return plenum cut open where the new air handler connects.
The installer is wiring the new heat pump air handler. He's set a new drain pan under it and added a float safety that shuts the system off if water backs up into the pan. He also ran a new 3/8 inch line set out to the heat pump.
Outside, the wrapped SwiftPro vans sit at the curb of a gray colonial.
Checking on my man Oscar over here. It is hot. You know what the temperature is up here right now? Maybe a hundred.
Feels hotter than that. Feels like maybe a hundred and ten. It does have a ridge vents up there, but not a lot of air movement going on. So, we got a heat pump air handler combination going on here.
You're working on the wiring right now? Yes. Put a new pan in, right? Yeah, new pan, new easy trap.
Nice. Looks good. Any challenges on this install? New 3/8 line set.
Okay, so you had to run a new 3/8 line set from the indoor coil, or the air handler rather, to the outdoor heat pump. Want to explain what that easy trap is for, Oscar? That's the safety for the condenser. So, it's a water safety, right?
safety. Yep. So, that will shut off the unit if it leaks too much, right? Sometimes the the drain was closed.
So, the pan is there to prevent water from leaking right into the house. And then, if it's leaking water into the pan though, you still want to shut it off so it can't overflow. That way it would shut the unit off and stop the water from coming back from the condensate line. So, that is the purpose.
And very important, a lot of houses we find don't have these water safeties, then all of a sudden you have a whole bunch of ceiling damage or wet insulation. That can be a disaster. It causes thousands or tens of thousands of damage real fast. Something very, very important.
These guys work hard and often hot conditions in the summertime, so we appreciate what they do. He's got a little Milwaukee fan blowing on him. He's working hard and just wrapping up the install.
Yes. Building code calls for a secondary pan under attic equipment that makes condensate, and most installers pair it with a float switch. If the main drain clogs, the switch shuts the system off before the pan overflows. Without it, you find out when water stains show up on the ceiling below.
