Replacing 10 Year Old AC Unit In Travel Trailer - Should I Replace Unit Or Whole System?  

Question:

Expert Reply:

Good morning Mark, at around 10 years old, I’d recommend replacing the whole system. These newer AC kits use R32 refrigerant, and newer AC components are not backward compatible with a lot of the older setups. On top of that, parts for older refrigerant systems are getting harder to find.

If your trailer has ceiling vents throughout, a complete ducted system like the Coleman-Mach Roughneck Mach 3 # CM95RR is a solid option. If it does not have ceiling ducts and the air only blows out of the main inside ceiling assembly, then you’d want a ductless system like the Signature Mach 3 # CM58RR or Roughneck Mach 3 # CM68RR instead.

The Roughneck models are built heavier duty for more vibration and off-road use.

If you want, tell me which style AC system and which RV you have and I’ll point you the right way.
