New Carrier APU not keeping truck cool.

Now I have 10 year old beast that can freeze to death ))) It's a Tripac . Ambient temp is 88F , blowing 33F into cab.

 

Check out the install. My carrier dealer told me most of the time the lack of cooling or heat with new installs come from not installing the air duct work properly. He said a lot of places try to cut corners and plumb the apu duct into the trucks sleeper duct. This doesn't work coz it will pump half your cooled or heated air out of the sleeper blower fan and not into your cab .

 

comfort pro-mo money mo problems.

 

Curious what his issue turned out to be? I have a carrier on new volvo 760. My vents are under lower bunk and I was cooking today in Florida. Carrier dealer said whoever installed should have installed vents at the bunk levels too instead of under bed. I bought a tornado fan aimed it up high. Its clipped right in the flow of the cold air forcing it up cab cooled to 73 after I did this. Heat index was 99 today. Now that sun is not beating on truck apu is cooling whole cab.

 

Brand spanking new huh must be frustrating to have it not work especially if your in the hot zone TX being new its under warranty best take it back and get it checked out i know that's not going to fix you hot sweaty situation for now however unless they've got some call out service or are willing to pay for a call out service it would be interesting to see if it plays up when you are in cooler conditions by rights if its brand new the unit should be functioning and keeping temps down to a reasonable level.

 

Went to dealer they tied into the sleeper vents of the truck plus 2 under lower bunk. All is working well on mine. 101 Heat index in Iowa today cab nice and comfy.

 

I have a new KW on order and have been thinking about the Comfort Pro, you’ve had yours for a bit now, how are feeling about it?

 

I prefer carrier over thermo king. My issue was a bad install nothing more.
