Prestons Guide

[Jaykline]

The house I inspected yesterday has a heat pump system (not uncommon here in Texas). The outside coil is a Lennox Model # HP22-511-1P. Serial number 5193B26215. According to Prestons: Manufactured in 1993; 47,000 BTU/h Capacity; EER/SEER 12.1.

The horizontal unit in the attic is also a Lennox (electric). Model number CH19-51-2. Serial # 5193J63621. I could not find this half of the heat pump team in Preston's. I'm fairly certain it is of the same vintage (particularly given the serial #), but I'm bothered because I could not find the model number in the guide. Don't think I wrote it down incorrectly. But I have done stupider things.

Don't have my copy of Prestons with me now, but this will gnaw at me until I figure it out. Am I overlooking something obvious? Any sage wisdom out there to point me in the right direction? Thanks.

I can't find it in my Blue book either.

I think you may have wrote it down wrong. I have Lennox numbers that begin with "CHP" and "CHA" but not "CH".

Sorry I can't be more help.

I frequently can only find the outside unit in Preston's, I'm not sure they list the evaporator units at all. When I find something else listed it's usually a gas furnace, not an evaporator.

My WAG is 4 ton unit(CH19-51-2), manufactured in '93 gathered from the sparse info I have in the Carson & Dunlop Technical Guide.

Thanks once again guys. I really appreciate the good feedback on this question and others I've asked on this forum.

Wonder why Prestons lists only the outside unit with electrically powered systems? I guess that's a question for them.
