Types of AC Units
There are several types of AC units you can choose from for your camper top. The most popular type is an overhead RV A/C installed on the roof, which blows air directly into the RV or distributes it through a ducting system.
These overhead units are powerful and efficient, but they can be expensive to replace and have a large power draw. They also add to the overall RV height, which might be a consideration if you're planning a road trip to tight spaces.
If you're looking for a more space-saving option, you might consider a window or wall-mounted unit. These are less common, but they're a great choice for smaller RVs.
Size and Layout
The size and layout of your RV play a significant role in determining the appropriate air conditioner size. Larger RVs with multiple rooms or compartments may require air conditioners with higher cooling capacities to effectively cool the entire space.

Smaller RVs or vans, on the other hand, may only need a smaller-capacity air conditioner to achieve the desired cooling effect. Consider the square footage and specific layout of your RV when selecting the size of the air conditioner.
A general size chart can be used as an estimate if your camper did not come with an air conditioner and you want to add one. Here is a rough guide to get you started:
This chart is just a starting point, and you should always consult the manufacturer's suggestion, which can be obtained by calling the manufacturer directly with your vehicle identification number (VIN).
Portable
Portable air conditioners are a great option for supplementing a roof or wall-mounted unit in your RV. They're often used in smaller RVs or as a temporary replacement.
One of the downsides of portable air conditioners is that they have reduced cooling capacity compared to other types of RV air conditioners.
However, they do have some positives, such as quiet operation and lower costs.
Here are some key pros and cons of portable RV air conditioners:
Portable air conditioners can be a good option for RVs without an air conditioner or as a temporary replacement, as they don't require significant modifications like cutting into the roof or walls.

Features and Specifications
When selecting a camper top AC unit, it's essential to consider the features that suit your needs. Not all brands offer the same options, so it's smart to select only what you need.
Some standard features to look for include a heat pump, which provides extra heat in colder months and works best above 40 degrees Fahrenheit. A heat strip is also a useful feature, designed to remove the chill, but it should not be a primary heat source.
A soft start feature can reduce start-up energy demands, allowing for a smaller generator. This is particularly useful for boondocking. A condensate pump channels condensation away from the roof and out a drain tube.
Here's a brief overview of some key features to consider:
Remember to choose an air conditioner with the right cooling capacity for your RV's size, measured in BTUs. A unit with insufficient cooling power may struggle to maintain a comfortable temperature, while an oversized unit may consume excess energy.

The right cooling capacity is essential to avoid these issues. A unit that's too small may not be able to keep up with the heat, but one that's too large will waste energy and money.
When choosing an air conditioner, make sure to select a unit with the right cooling capacity for the size of your vehicle. This will ensure that you stay cool and comfortable without breaking the bank.
Energy Efficiency
Energy efficiency is not only important for reducing your carbon footprint but also for maximizing the life of your RV batteries and minimizing energy costs.
Air conditioners with energy-saving features can optimize energy consumption without compromising cooling performance. These features include variable speed compressors and smart thermostats.
Variable speed compressors adjust the compressor speed to match the cooling demand, reducing energy waste. This can lead to significant energy savings over time.
A smart thermostat can learn your temperature preferences and adjust the temperature accordingly, ensuring you're comfortable while minimizing energy consumption.
