Have a double wide mobile with intertherm electric. I get hot air in the front half of the house an cool air on the back side of the house.

If I bump up the thermostat a bit it will blow hot air on the back half of the house then it goes back to cool air but the front half is still hot air.

I have to set the thermostat to 75 to make the back half warm but the front half of the house is hot. I replace the heat sequencer and blower motor a few years ago. All the ductwork is good. I could use some help on this problem. Thanks

Assuming proper insulation and draft prevention, closing/restricting forward vents may force more hot air further downstream and equalize your overall temperature. I think it's a circulation problem, more than equipment failure from what you have written.

I take your word also that your ductwork downstream is good.

Let me guess. The furnace is in the front part of the house.
If so, what you have is typical manufactured housing duct work which usually isn't worth a plugged nickel. For those who were willing to spend the $$$, I've redone the ducts with good success but it usually means almost a complete tear out & re-installation.

No its in the back half

Fooled me. Extremely rare to hear the opposite side of the home gets more air than does the side with the furnace.

When you refer to the front & back of the home, I presume you are talking about 'splitting' the structure lengthwise. Is that true?

Nearly all manufactured homes have a "crossover" duct to tie the two main duct halves together. Often, as a cheap way out, we add another crossover duct. In your case it seems the crossover may be too large. A damper could be installed to restrict the amount of air going to the non furnace side.

Have you lived there long enough to know if this uneven heat condition existed last winter?

Thank you,
'splitting' the structure lengthwise. Is that true? (true)
crossover may be too large. I did replace the crossover last year.
I paid a boy to hook it up for me. I"d say the flex pipe is to big.

I've been going crazy trying to work though this.
Now for a temporary fix can I use some zip ties on the flex pipe to chock it
Down some. Or should I just replace it?

I don't suggest trying to choke down the flex with zip ties. I usually doesn't work very well because the flex has a spirial wrapped wire in it. The ideal thing would be to install an adjustable damper. By doing so it gives you the ability to open it back up in the summer if you find you need more air on that side for A/C.
Do you know what size the flex for the crossover is & where in relation to the heater it connects?
