Concerned about partially disconnected (?) exhaust on my recently installed furnace
This furnace was installed at the end of winter last year right after the blizzard ( during which our Old Furnace had failed, because of course) he came back to install the AC on top of it this spring and for some reason when I turned on the heat for the first time this season (last week) I felt like I needed to go down and poke around (kind of trying to figure out which, heat or aux, setting on my thermostat controlled the furnace in which controlled the heat pump) and I found the exhaust kind of what I felt like was disconnected. Am I wrong? Should this not be sealed with purple at the top and reach all the way down into the built-in exhaust port thing? I'm a homeowner with nearly no knowledge about this stuff.
(we've already decided to get a new HVAC guy/ company after this install. We really had wanted him to fix our old one not to buy a new one but it was a unit from 1999 and both it and the AC coil have been repaired multiple times)
Eta: there is enough pipe so that it can be inserted both into the exhaust Outlet on the furnace and the upper elbow but only just. And then still it's not sealed with any PVC cement. I have some PVC cement and I could connect it at the elbow. Should i?
