Lennox "roof top unit"

[Byron]

I'm recovering refrigerant today to start decommissioning a Lennox packaged roof unit that consists of 3 Pulse 21's that I've never seen before and thought people may find it interesting, this is a full prefab unit manufactured by Lennox. I haven't seen one in my 16 years in the trade so I'm sure many others haven't either, so I figured I may as well share.

Wow. It's more like a custom shed that's customizable with existing residential units. I've only ever seen 3 pulse furnaces and I'm quite certain a won't ever come across a packaged system like this.

I've changed 100s of those heat exchangers back in the day. Those look like a nightmare to work on let one change out a heat exchanger.

Must sound great with three running at once
