Re: Evaporator coil


Well many years ago, when I was a residential installer, we would always install the coil at least 6 inches above the oil furnace cabinet. This would ensure the hi heat from the oil furnace wouldn’t melt the cheap plastic condensate pan. However, with a height restriction , this may not be possible. If your plenum has 1 main trunk duct coming off of it, is it possible to install a vertical coil in the main trunk before any branch duct?

If you have a wholesale house that Carries heil or icp (southern refrigeration here) you can get a N coil that pretty much only thing we used on fossil fuel or trailer furnaces. They usually fit well an round 14 to 16 inch tall.
Just make sure you get all sides sealed. Installers left one side with no shelf to set on an air was bypassing coil.
