Small RV rooftop AC and heat units are a game-changer for comfortable camping. They provide efficient cooling and heating for your RV, making your outdoor adventures more enjoyable.
A typical small RV rooftop AC unit is around 13,500 BTU, which is enough to cool a small to medium-sized RV. Some units can even be as low as 10,000 BTU, perfect for tiny RVs or trailers.
When choosing a rooftop AC unit, consider the size of your RV and the number of people it will accommodate. A general rule of thumb is to choose a unit that can cool 300-400 square feet of space.
Rooftop AC units can be more energy-efficient than traditional window units, especially if you choose a unit with a high SEER rating, such as those found in the article section on "Rooftop AC Unit Efficiency".

Choosing the Right RV AC Unit
Choosing the right RV AC unit is crucial for effective cooling and optimal comfort during your outdoor travels. It's essential to consider the size of the unit, as a unit that's too small won't be able to cool your RV efficiently, while a unit that's too large will consume too much energy and may not fit in your RV's available roof space.
To determine the ideal size of air conditioner for your RV, consider the BTU rating. A higher BTU rating means the unit can cool a larger space. For example, the Coleman Mach 15+ 48204C866 has a 15,000 BTU rating, while the Zero Breeze Mark 2 has a 2,300 BTU rating.
Some RV air conditioners are designed to be more energy-efficient than others. Look for units with energy-saving features, such as variable speed compressors and smart thermostats. For example, the Dometic Brisk II has a variable speed compressor that optimizes energy consumption without compromising cooling performance.
Here are some key considerations to help you determine the ideal size of air conditioner for your RV:
- BTU rating: A higher BTU rating means the unit can cool a larger space.
- Available roof space: Measure your RV's available roof space to ensure the unit fits comfortably.
- Weight: Consider the weight of the unit and ensure it doesn't exceed your RV's roof weight capacity.
- Energy efficiency: Look for units with energy-saving features to reduce your energy costs and carbon footprint.
By considering these factors, you can choose the right RV AC unit for your needs and enjoy a comfortable and cool ride during your outdoor adventures.
Finding the Best
Choosing the right RV AC unit can be a daunting task, but with the right information, you can make an informed decision. Measuring your RV's available roof space and checking how much weight the roof can carry is crucial before purchasing an RV air conditioner.
The weight of the AC unit is a significant consideration. For example, rooftop models can range from around 65 pounds to 90 pounds. If you're unsure how much weight your RV roof can take, choose a lighter and more compact unit.
Dometic offers a range of RV air conditioners designed to meet the diverse needs of recreational vehicle owners. They understand the importance of selecting the appropriate size, and their products are designed to ensure effective cooling and optimal comfort during your outdoor travels.
Here are some key considerations to help you in your search for the perfect RV air conditioner:
- BTU ratings: Look for an AC unit with a BTU rating that matches your RV's size and insulation.
- Power sources: Consider whether you need a unit that can run on a generator or one that can be plugged into a standard outlet.
- Installation compatibility: Make sure the AC unit you choose is compatible with your RV's roof and electrical system.
- Price: Set a budget and look for AC units that meet your needs within that range.

A unit with insufficient cooling power may struggle to maintain a comfortable temperature, while an oversized unit may consume excess energy. To choose the right cooling capacity, you need to consider the size of your RV.
For small to medium-sized RVs, a 13,500 BTU air conditioner like the Dometic Brisk II is a good option. This unit provides plenty of cooling power and is compact in size.

Key Features to Consider
When searching for the perfect small RV rooftop AC and heat unit, there are several key features to consider.
Cooling capacity is a crucial factor to think about, as it directly affects how well the unit can keep your RV cool. Consider your RV's size and the number of people you'll be traveling with to determine the right cooling capacity for your needs.
Noise level is another important feature to consider, especially if you plan on using the unit while sleeping or relaxing inside your RV.
Remote control operation, programmable timers, and adjustable airflow direction are all additional features that can enhance your comfort and convenience.

Additional Features
Dometic's RV air conditioners come with a range of additional features that can enhance your comfort and convenience.
Remote control operation is a feature that can be especially useful, allowing you to adjust the temperature and airflow from a distance.
Programmable timers can also be a great feature to have, enabling you to set the air conditioner to turn on and off at specific times.

Air purification systems can be a valuable addition, helping to remove impurities and allergens from the air.
Installation and Budget
When choosing a small RV rooftop AC and heat unit, consider the installation process. Look for a unit with simple installation, as this will save you time and effort.
You'll also want to ensure the unit comes with a gasket that seals the roof opening and prevents cool and hot air leakage through the connecting surface.
This will help you avoid costly repairs down the line and keep your RV comfortable and energy-efficient.
Don't Overload Your System
Most RVs come with a 30-amp and 120-volt electrical system that can supply a maximum of 3,600 watts of power.
Double-check the power draw of your chosen RV air conditioner to avoid overloading your system.
The system is generally further divided into 15-amp circuits to prevent overloading and potential electrical fires.
Choose a unit with a maximum power draw of 13 amps or less to avoid constantly tripping electrical circuits and creating potential hazards.
If you plug an RV air conditioner drawing more than 15 amps into a 15A circuit, it will trip the circuit breaker.
Domestic Universal Distribution Box

The Domestic Universal Distribution Box is a great option for those who want flexibility in their air distribution system. It's designed for non-ducted applications.
You can control the airflow with manual ceiling controls, which is a simple and effective way to adjust the temperature in your home. This type of control is perfect for smaller spaces or areas where a wall thermostat won't fit.
For larger homes or areas with multiple rooms, you can use the Domestic Universal Distribution Box with a wall thermostat. This allows you to control the temperature from a central location, making it easier to heat or cool your entire home.
Simple Installation Unit
If you're looking for a unit with simple installation, you're in luck. The Dometic Brisk II has a compact form factor, making it a great choice. It weighs less than 80 pounds, which is relatively light compared to other models.
This unit's compact size and weight make it easier to install, especially for those who are new to RV air conditioner installation. The Dometic Brisk II's compact form factor is also a plus for those with limited space.
The unit's dimensions are 12.7 x 29.18 x 27.23 inches, which is a decent size for a rooftop air conditioner. However, keep in mind that the packaging can be a bit of a hassle, with some users reporting cracked shrouds and busted connection points.
Here are the key features of the Dometic Brisk II:
Overall, the Dometic Brisk II is a great choice for those looking for a unit with simple installation. Just be aware of the potential packaging issues.
Set Your Budget in Advance
Setting your budget in advance is crucial when shopping for an RV air conditioner. This will help you focus on units you can afford.
RV air conditioners can be expensive, with prices ranging from around $170 to nearly $2,000. You'll want to choose a unit that fits within your budget.
Most rooftop ACs don't include the indoor ceiling assembly necessary to operate them. You'll need to set aside an additional $100-$200 for the plenum when drafting your budget.
Understanding RV AC Units
To beat the heat on your travels, it's essential to understand RV AC units.
Rooftop units are a popular choice for small RVs, offering a compact and efficient way to cool your space.
You'll want to consider the BTU rating of your RV AC unit, as it determines how well it can cool your space. A higher BTU rating generally means better cooling performance.
To ensure compatibility, check the power source and installation requirements of your RV AC unit before making a purchase.
Portable systems are another option, but they can be less efficient and more expensive to operate than rooftop units.
