I have a four unit apartment building built in 1939. In Los Angeles. The two downstairs units have a gas floor furnace. I need to replace the units, but do not know where to purchase them. The unit is built into the floor and the wall. It is 15 inches wide and about 22 to 23 inches deep. Can you help?
Thank you

Katherine

I believe you may have to go with a different design. There are floor furnaces still manufactured but they are way different than what you have. I would call a few local contractors to get information as to what they can do for you with this situation you have.
