When it comes to choosing an air conditioning unit for your RV or mobile home, two of the most popular brands in the market are Coleman Mach and Dometic. In this article, we'll compare the two brands across several key areas to help you make an informed decision.

Size and Capacity

One of the most important factors to consider when choosing an air conditioning unit is size and capacity. You want to make sure that the unit is the right size for your RV or mobile home and has enough cooling capacity to keep you comfortable in hot weather.

Dometic:

  • Units come in various sizes and cooling capacities, with their largest unit, the Penguin II, having a cooling capacity of 15,000 BTUs.
  • Overall, Dometic units tend to be smaller than Coleman Mach units.

When choosing between Coleman Mach and Dometic, it's important to consider the size of your RV or mobile home. If you have a larger RV or mobile home, a Coleman Mach unit with a higher cooling capacity may be a better fit. If you have a smaller RV or mobile home, a Dometic unit may be more appropriate.

Noise Level

Another factor to consider when choosing an air conditioning unit is noise level. You want an air conditioning unit that will keep you cool without being too loud and disrupting your peace and quiet.
