Various Heil 5000, Lennox, Frigidaire, and Heat Controller central air conditioners! (Not running)

These units are located at an older commercial building in my town that I’ve filmed at before a few times. It has been a while since I got a video of all these. The last time I filmed these was in 2020 I think. This place has a very interesting bunch of units in my opinion. The Heat Controller unit I find especially interesting. I’m not sure what exact year the Heat Controller is from but I plan to get it starting up and some other units here this coming spring and summer! That unit and the 1992 Heil are my favorite units here! Recorded January 26, 2025.
Outro music: Freedom by Axity.

3:01 My aunt’s old house near Madison, AL used to have an identical unit to this from 1997 or 98. Also a package unit version as well that lasted about 12 years
