2005 Southwind Posted January 3, 2021 Report Share Posted January 3, 2021 Just had a new rooftop ac installed in my class C. Prior model was not a heat pump type, it was a regular ac. The installer didn't replace the inside lower panel evidently they thought it would work. Now I find out that I have no heat so I guess i need to find the correct lower unit for heat pump model. I have checked everywhere and anything to do with Coleman is out of stock. Has anyone ran into this problem before? thanks Quote Link to comment Share on other sites More sharing options...
docj Posted January 3, 2021 Report Share Posted January 3, 2021 The "lower assembly" in a Coleman is specific to the heat pump, as you have surmised. We had two Mach 8+ heat pumps installed to replace old A/Cs and they work just fine. If you had someone install them why not go back and have him fix his mistake?

TXiceman Posted January 3, 2021 Report Share Posted January 3, 2021 (edited) Another vote to take the problem back to the original installer. We have two Mach 8 Plus HP and they work great in both heating and cooling mode. I do find that they are noisier and seem to vibrate a bit more than the older Mach units. And yes, they are properly mounted. I did find a lot of loose bolts and nuts that needed tightening and some wires and lines needed clamping. You might check a salvage place like Colaw to see if they have a salvaged ceiling assembly for your unit.

The only problem with taking it back is that it appears to me that the RV tec who put it in was incompetent and may make things even worse. Is it too late to stop the payment for that installation? If not I would take that action first, then find someone to correct the installation and deduct the additional cost from the amount that you pay the first guy.
