blazenut Posted October 13, 2009 Report Share Posted October 13, 2009 This was in a condo i did today, the electric furnace was installed horrizontile in the top of a closet, and the compressor was in a closet on the balcony. The condo was built 37 years ago. Both manufactured by DNP Company (division of Carrier), Furnace: Serial # 38B 48562 Model#24AVHFC-108 Compressor: Serial #4C 14241 Model#241WC-509K Any idea what the date of manufacture are, they both looked old, lots of corrosion.

Erby Posted October 14, 2009 Report Share Posted October 14, 2009 The best way is to buy a Preston's guide Second best way is to take a picture of the data plate and put that up. Furnace looks to be an 85. No idea on the compressor serial numbers. Do you have the serial number of the outside unit itself or just the compressor. DNP stands for Day/Night/Payne Link to comment Share on other sites More sharing options...
inspector57 Posted October 14, 2009 Report Share Posted October 14, 2009 Too old to care. If it lives another day I would be surprised. Link to comment Share on other sites More sharing options...
hausdok Posted October 14, 2009 Report Share Posted October 14, 2009 Either: Week followed by year for Bryant code 1964 to 1979 Furnace is the 38th week of 1973. Compressor is 4th week of 1974. or Day and Night 70 and later Letter month followed by year of manufacture - beginning in 1970 which would be: Furnace is February 1974 Compressor is March 1971. ONE TEAM - ONE FIGHT!!! Mike Link to comment Share on other sites More sharing options...
