    Question Hey Old Timers!! Williamson 5 in 1

    OK maybe not all old timers!

    Williamson produced a 5 in 1 furnace.

    I remember it, worked on them for years......Just don't remember what the 5 in 1 was.

    What were the five things they put in the furnace for the 5 in 1???

    This is just a guess...

    - Heating section (burners, heat exchanger, etc.)
    - Air filter (EAC perhaps?)
    - Humidifier?
    - Evap. coil
    - Some sort of ventilation (fresh air intake?)

    tech support: I guess it's official..........I'm an 'old timer' cause I sure remember these. Didn't see many but I was always intrigued by the 5 in1 concept.

    Seems to me I remember the 5 in 1 consisting of heating section, evaporator coil, blower section, humidifier, and air cleaner. Also, if I remember, the one's that I dealt with were in a low-boy configuration. I don't believe there was any 'fresh air intake' as that had not become 'fashionable' at that time so wasn't a consideration.

    all the best, Irish

    Gawd I guess I am an old timer also

    As early in my career we installed a number of these 5-in 1, a number of which are still out in the field installed in the mid 70's. These were a great furnace, especially for their time.

    These were furnace that were assembled in the basement, they didn't come in just one carton but many cartons

    The 5 in 1 stands for the following

    Heating
    Cooling
    Dehumidification
    Humidification
    Air Cleaning

    Does any one know if I can take out the electronic filter box and put in just a disposable air filter. My system has 3 layers of filters #1-screen,#2-electronic filter and #3 metal filter. I was told the system doesn't work so I thought I could take out all the metal ones and put in a paper filter.

    Yes, take the filter out and measure them as if they were in the in the blower area. See if you can get a Honeywell Filter the same size as that. YOu can find these Honeywell at Home Depot.

    Which metal filters can I replace with paper. #1 thin screen, #2 18in x 21in x
    6 1/2 and the 3rd is 18 x 21 x 1in. I did see the honeywell @ home depot and I thought I saw the larger one also.

    We had one in our house as a kid. I worked on a few two and loved them (the original Williamson 5 in 1). I do recall a funny DC thermostat on at least one that looked like a regular T87 but it wasnt. It's been a while. If I recall the gas valve failed on one and I had to modify it to run on 24v ac and ended up having to change the stat with it.

    I think it was just a standard Honeywell EAC and an Aprilaire bypass humidifier (inside unit with no pipe). Measure the two big cells together as they would be installed and that's the filter you want to put in there but remember it will be 4" wide I think.

    Trivia

    If my memory serves me correct, I think these units even came with a small bottle of green touch-up paint in case of any scratches occuring during the install. Am I correct or is my mind starting to go on me?....
    I came into this world with nothing, I still have most of it left....
