What's the replacement for my existing AC?

Coleman-Mach Model Number Revisions

If you own an RV, then you know the importance of having a good air conditioner. The Coleman-Mach RV rooftop air conditioners are one of the most popular choices among RVers, and for good reason. These units are reliable, efficient, and durable. However, what many people don't know is that these air conditioners have gone through several model number revisions over the years. In this blog post, we'll use the example of the Coleman-Mach 8 model number "47024-079" and compare it to some of its older model numbers.Let's take a look at some of the older model numbers for this same (or equivalent) air conditioner. Here are some of the most common ones:


9024A879, 47024-879, 49024-879,47074-879, 47074A879, 9024-679, 49024A879, 9024-779, 9024-879, 9024A779, 9024C879, 47024B879, 47024A879, 47024-879, 47074-879, 47074B879, 47074B679, 47074-679


As you can see, there are many different model numbers for this air conditioner. So, why are there so many revisions? The answer is simple: improvements, engineering design changes and component vendors changing with the unit. As Coleman-Mach/Airxcel Inc.,(RV Group) has made improvements to the design and technology of their air conditioners, they have revised the model numbers to reflect these changes.

For example, the "9024A879" model number was one of the earliest versions of this air conditioner. The next example is the "9024C879" model number. This version has had two engineering design changes since the first model mentiond, the "9024A879".  These revision changes are not always public information and can often be something as small as adding or removing a screw somewhere on the unit. 


What's the replacement for my existing/older unit? The manufacturer's tool for suggesting replacement model numbers.

This is probably one of the most commonly asked question we get!  Luckily the manufacturer has a tool that helps us answer this question for our customers.  The tool can be found on the manufacturer's website on the page: "Find A Replacement for Discontinued AC Models" .  All you have to do is enter your existing model number (IE: 9024A879), and the result that comes back is the 47024-079. It's worth noting though that this tool isn't always completely up to date. So if they recommend a model number that you cannot seem to locate, feel free to reachout to us and ask any questions that you may have!

Something to be aware of is that, just because there is a recommended replacement for your existing model number, it is possible that many of the other units will work in it's place.  For instance; if you previously had a 47003A876 (which according the the part number nomenclature, is an ultra low-profile Mach 8 13,500 BTU Heat Pump), if you don't utilize the heat pump feature, you can replace it with the latest equivalent air conditioner, which is the 47203-076.

In Conclusion...

The Coleman-Mach RV rooftop air conditioners have undergone several model number revisions over the years, reflecting advancements in technology and improvements to the design of the units and component vendor changes. By understanding the different model numbers and their meanings, you can make an informed decision when purchasing an air conditioner for your RV. The next time you see a Coleman-Mach air conditioner with a different model number, you'll know that it's likely a newer, more advanced version of the unit you already know and love.

So, if you're in the market for replacing your existing Coleman-Mach RV rooftop air conditioner, it's important to pay attention to the model number. While the basic features of the unit may be the same across multiple model numbers, there may be differences in design, fitment, or vendors of the components inside, such as the compressor. By understanding the different model numbers and their revisions, you can make an informed decision and choose the best air conditioner for your RV.
