A friend had filters removed from furnace. Trying to determine where they go back in. It appears there is no place though the instructions say to clean optional filters (see user manual for location). However, the user manual is not available.

Get an HVAC contractor to take a look at it. We usually remove the blower assembly, measure the back side of the unit, a fab a piece of 90° metal to help retain the air filter down. Like a shelf bracket that runs the legnth of the back side. The original installer didn't use a filter base. The unit sits on top of it and it's easy to change the filter. You can fabricate 1, or possibly find a pc. at a hardware store. Thin 90 degree metal. Hope this helps!
Your furnace filter or A/C filter is located next to the floor in your cold air return into the furnace. Your other problem is your condensate line out of the A/C box that sits on top of your furnace is plugged. Replace your filter in the cold air duct, and remove your condensate line from the A/C box and blow air in the line to remove the clog in the line.
You will have to remove the outer cover(s) to expose the blower chamber where the filter is mounted. Usually, the filter is clamped in place over the cold air return. Release the clamp, slide out the old filter, install the new filter and clamp it in place. Reinstall the cover(s) and your furnace is good to go.
Hi, this is a pretty generic answer, so it's really more of a guideline.
Some come attached at the bottom of the furnace, and are generally removed when the unit is installed. If it's there, it pulls out like a drawer.
Most furnaces are installed on a platform, which is really a box (plenum). Below the platform, and opening to the room, is a louvered grate. Air is drawn in through the grate and into the furnace. The grate has clips on it to keep it closed. Loosening the clip(s) allows the grate to be opened. The filter is usually behind there.
Filters are usually added to the sheetmetal seperate from the furnace. All air must be filtered before entering the furnace. Turn on heat and feel ductwork to determine which direction air flow goes, warm will be supply and room temp. will be return. Filter should be on return side of furnace. Some of them may be filter grilles located in a central reurn on older homes with only one return in a hallway or sometimes the correct ductwork is not installed and they are inside the bottom panel where return ducts connect
Hi, sometimes depending if the unit is an up flow or down flow that depends where they put the filter.If you don't have a return grill in the ceiling, then it would be in the bottom of your furnace. I am sure its hard to remove as it is new, but i am sure it is there.Sometimes there is a grill on the lower wall beside the furnace they could have put it in. They may not have installed one? Good Luck, Sincerely, Shastalaker7
Usually a Filter rack is installe don the outside of the furnace for easy access....if this is not the case , turn off the power and carefully remove the bottom panel of the furnace (The top may have to be removed first)....The edges are sharp so use gloves....the filter should then be immediately on the inside left or right side of the furnace depending on which side the return air is on....if no filter is present do you have an Electronic air Cleaner???? In that case no other filter is required...if all else fails and the furnace is under warranty call the Installers back
Contact your nearest Ruud DISTRIBUTOR, usually The Noland Company, and ask them if they could go into the historical documents and print out or send you the files for the wiring, spec's and parts breakdown. From the model number, that unit is rated for 3 tons of a/c. You can find a 3 ton coil that will fit in the space and get a straight cool condenser of 3 tons cooling and swap thermostats so it brings on the furnace and fan in heat and the condenser and fan in cooling. Or just add a simple White - Rogers model 444 for the cooling. Ron
MAYBE IT DOES NEED IF THE FILTER IN THE COLD AIR RETURN GRILL MAKE SURE THEIR IS NO FILTER IN THIS FIRST , AS 2 FILTERS ARE NOT BETTER THAN ONE WHEN COME TO ELECTRIC FURN AND H/P ALSO IS THIS A UP-FLOW ,DOWN FLOW OR HORZ MEANING AIR #1 RTN IN BOTTOM DISCHARGE COMING OUT OF TOP OR#2 COLD AIR COMING IN TOP AND DISCHARGE OUT OF BOTTOM OR #3FURNACE LAYING SIDE-WAYS AIR COMING IN ONE END AND OUT OTHER THESE WOULD DETERMINE FILTER LOCATIONS
First you have to get the old filter/s out. If not it will cause big problems in a short time. Use a coat hanger to grab the filter if you cant reach it. When you remove the old filter you will probably see how to install new ones. I think more than one filter is required for this furnace. Note the sizes of the old filters and buy the same replacements.
Don't worry about cutting some tape if needed. You can get another roll at any hardware supply. If all else fails, measure the interior of the return box and buy the right size filters. Remember, you must remove the existing filters!
