Drastic variance in temp
I have a Coleman Model G9T06010UPB13C furnace, installed 2007.
We just purchased the house and I noticed that the air coming out of the vents on one side of the house is drastically warmer then the other.
Air temp coming out of the east side vents is at least 15 degrees cooler than the west side vents.
The duct works come straight off of the top of the furnace, plenum is large enough for an A-coil but doesn't have one (no central a/c) then tees off going east and west. If you place your hands on each side one is really hot the other cool.
No damper in either side of the tee (just in the take offs), there is a humidifier that disconnected but still attached.
Here is a picture of the plenum coming out of the top of the furnace, attached is the humidifier that is not connected to the return and has been capped and sealed awaiting removal.
There is a tee attached to the top of the plenum as I mentioned before. There is no damper in either side of the plenum.
All of the rounds coming off for both sides of the house have dampers and all the registers have dampers also.
Temp out of the left side (marked with X tape) taken at first take (disconnected at spin in and used digital thermometer) off 3' from the x is 61 degrees.
Temp out or right side (plain tape) taken 41" from the tape is 88 degrees temp taken with the same method.
Thanks in advance for your knowledge.
