I inspected a home yesterday and the oil furnace was made by Metzger Machine Corp. Home was built in 1965, A/C unit installed in 1996.
Oil furnace model WHB0-10A, Ser # 6903-5X2. The furnace doesn’t look old enough to be from 1969 and doesn’t look new enough to be from 2003. I can’t find a link to decode the serial #.
Anyone familiar with this? Don’t have a lot of oil furnaces here.
