I just replaced a Coleman-Mach 15 with Heat Pump and ordered through
RV Products Shop in Peck, KS -- they are very near the Wichita KS factory.
The whole process took less than 10 days including confirming stock, ordering, shipping to AZ, removing the bad one-year old unit (freon leaked out) the installation of the new unit by a local mobile tech.
The only question is whether I will be able to offset some of the total cost of parts and labor under warranty. The temps in AZ are reaching 100F+ every day now so the need was urgent.
