SOURCE: How can I validate the tonage of my Ruud air
you must have very old equipment are you sure of the model and serial number it might be a 69 if the serial number is the m0696. Tom double check those numbers.

a forced-air distribution system is just what the name implies. Air is forced from the furnace through ducts to registers in various rooms. Besides warming the air, the blower system that distributes the warmed air also returns the cold air to the furnace so it can be rewarmed and distributed to the rooms again.
A forced-air distribution system uses a blower to distribute warmed air and to
return cold air to the furnace so it can be rewarmed and distributed again.
A forced-air system is also efficient for distributing cool air from a central air conditioner with the same ducts, registers, and blower. There is little that can go wrong with a forced-air system. The big problems typically include noise and blockage of airflow, usually caused by dirt or by furniture or draperies blocking the registers. Forced-air systems should be cleaned and maintained regularly.
Floor registers are slip-fit into ducts or are held by retaining screws on the frame of the register. Wall and ceiling registers are also held in place by retaining screws on the frame of the register. Duct joints are usually slip-fit and held with sheet-metal screws or duct tape. The ducts are supported by wire or metal strap hangers nailed or screwed to wooden framing members such as studs and rafters. All of these parts are easy to disassemble. Lay them out in order as you work so you'll be able to reassemble them properly.
A problem can arise with this type of system in which the temperature of different rooms varies widely.
Forced-air systems often go out of balance, causing some of the rooms in a home to be too hot or too cold. The furnace is usually not to blame; the problem is caused by ducts and registers that are not properly set. You should balance the system while the furnace is turned on.
To balance a forced-air system, open all the ducts and registers in the system. There may be dampers in various ducts that need to be turned to open the ducts. The damper is open when it's turned parallel with the top and bottom of the ducting.
Next, gather six or seven thermometers and get them all to have about the same temperature reading. You can do this by laying out the thermometers together for about 30 minutes and then noting any discrepancies. Tape the thermometers on the walls of each room so each thermometer is about 36 inches up from the floor, away from the hot air register or cold air return. Wait one hour, then take a thermometer reading in each room when the heat is on. If one room shows a higher temperature than an adjoining room, close the damper or register slightly in the hotter room.
Follow this procedure for each room in your home, opening and closing dampers and registers until the same temperature is maintained in each room or the temperature balance you want is reached. The thermostat to the furnace should be kept at the same reading while you balance the system.
