Jaykline Posted May 17, 2004 Report Share Posted May 17, 2004 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. Quote Link to comment Share on other sites More sharing options...
swarga Posted May 17, 2004 Report Share Posted May 17, 2004 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. Quote Link to comment Share on other sites More sharing options...
Brian G Posted May 17, 2004 Report Share Posted May 17, 2004 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. Brian G. Quote Link to comment Share on other sites More sharing options...
DonTx Posted May 17, 2004 Report Share Posted May 17, 2004 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. Quote Link to comment Share on other sites More sharing options...
Jaykline Posted May 18, 2004 Author Report Share Posted May 18, 2004 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. Quote Link to comment Share on other sites More sharing options...
