Choosing the Right RV Rooftop Air Conditioner
Before you pick a brand, you need to understand the fundamentals. The single most important spec is the BTU (British Thermal Unit) rating, which measures cooling power. A 13,500 BTU unit is a common standard and works well for smaller to mid-sized RVs, while larger rigs or those destined for desert climates will need the extra muscle of a 15,000 BTU model.
But more power isn’t always better. An oversized AC in a small, well-insulated van will "short-cycle"—blasting cold air, shutting off, and turning back on again frequently. This is inefficient, hard on the components, and terrible at dehumidifying the air, leaving you with a cold but clammy space. You have to match the machine to your rig’s size, insulation, and the climates you plan to visit.
Finally, consider your power reality. A high-BTU unit draws more amperage, which can be a problem if you’re on a 30-amp hookup and want to run the microwave. For boondockers, the start-up surge of a big AC can be too much for a small generator or inverter. These are the real-world tradeoffs that matter more than any marketing slogan.
Dometic Penguin II: The Ultimate Low-Profile AC
Stay cool on the road with the Dometic Penguin II 13,500 BTU low-profile rooftop air conditioner. Its aerodynamic shroud reduces wind resistance, and it's compatible with ducted or non-ducted cooling systems.
If you’ve ever held your breath while approaching a low-clearance bridge or a gas station awning, the Dometic Penguin II is for you. Its primary advantage is its incredibly low profile, sitting under 10 inches tall. This significantly reduces the risk of snagging a tree branch or damaging your roof, a constant concern for anyone who ventures off the beaten path.
This sleek design doesn’t just help with clearance; it’s also more aerodynamic, which can offer a marginal improvement in fuel economy on long travel days. While it’s available in both 13,500 and 15,000 BTU configurations, its performance is geared more toward efficiency than raw, overwhelming power. It cools effectively and is compatible with Dometic’s advanced multi-zone thermostat systems, making it a top choice for newer, integrated RVs.
The tradeoff for this slim, high-tech package is the price. The Penguin II is a premium unit, and you pay for the engineering that fits capable cooling into such a compact shell. But for those who need to maximize clearance without sacrificing comfort, it’s the undisputed king of low-profile design.
Coleman-Mach 15: Powerful Cooling for Hot Climates
Cool your RV with the Coleman-Mach 15 Plus, delivering 15,000 BTU cooling power in a medium-profile black unit. This efficient air conditioner comes complete with a protective wood skid for secure transport.
The Coleman-Mach 15 is the brute of the RV air conditioning world, and I mean that as a compliment. With a true 15,000 BTU rating, this unit is designed for one thing: to battle extreme heat and win. If your travel plans include summer in Arizona, Florida, or Texas, this is your most reliable weapon against triple-digit temperatures.
There’s nothing fancy about the Mach 15. It’s built with a focus on durability and raw cooling output, featuring a large evaporator and condenser coils that move a serious amount of air. Its robust construction has made it a favorite among full-timers who demand reliability day in and day out. It just works.
This power comes with compromises. The Mach 15 is one of the taller and heavier units on the market, and it’s certainly not the quietest. Its power draw, especially on startup, is significant, so you’ll need a robust electrical system, a 30-amp hookup at a minimum, or a capable generator. But if maximum cooling power is your non-negotiable priority, this is the workhorse you can count on.
RecPro Houghton: Quietest AC for Peaceful RVing
Stay cool and comfortable in your RV with the RecPro 13.5K BTU air conditioner. This quiet unit features a dehumidifying function and user-friendly controls, including a remote and LED display.
Traditional RV air conditioners have a reputation for being loud enough to drown out a normal conversation. The RecPro Houghton series completely shatters that expectation. These units are engineered from the ground up for quiet operation, making them a game-changer for anyone who values peace and quiet.
The difference is immediately noticeable. Inside the RV, the Houghton runs at a low hum rather than a deafening roar, making it possible to sleep, work, or watch TV without blasting the volume. This is a massive quality-of-life improvement, especially for light sleepers or those who work from their rig. Many models also come with a built-in soft-start, which reduces the initial power surge and makes them much friendlier to smaller generators and battery systems.
While RecPro might not have the decades-long name recognition of Dometic or Coleman, they’ve earned a fiercely loyal following by focusing on this one critical feature. If the thought of another summer spent shouting over your AC makes you cringe, the Houghton is the quiet solution you’ve been looking for.
Furrion Chill: Sleek Design with Heat Pump Option
Experience superior cooling with the Furrion Chill Cube 18k BTU RV rooftop air conditioner. Its variable speed compressor ensures quiet, efficient operation and faster cool-down, while the lightweight, aerodynamic design enhances RV performance.
Furrion has made a name for itself by bringing modern aesthetics and technology to the RV industry, and the Chill air conditioner is no exception. With its sleek, aerodynamic shroud and LED lighting, it simply looks more modern than many of its competitors. But the appeal goes beyond looks.
The standout feature for many nomads is the optional heat pump. A heat pump operates like an air conditioner in reverse, efficiently pulling heat from the outside air to warm your RV. This is incredibly useful for taking the chill off on cool mornings or evenings in the spring and fall without having to burn through your propane with the furnace. It’s an all-in-one climate solution.
Furrion also emphasizes performance, incorporating vibration-dampening technology to reduce noise and improve user comfort. Paired with their wall thermostats, the Chill system offers a user-friendly experience that feels more residential than rustic. It’s a fantastic choice for the RVer who wants a blend of modern style, year-round functionality, and solid performance.
Dometic Brisk II: A Reliable and Powerful Workhorse
This Dometic Brisk II 15K BTU air conditioner provides powerful cooling for your RV. It's designed for non-ducted applications, requiring a separate air distribution box for efficient air flow.
The Dometic Brisk II is one of the most common rooftop ACs you’ll see in any campground, and for good reason. It represents the industry standard for a reliable, no-nonsense air conditioner that delivers excellent performance at a reasonable price. It’s the unit manufacturers often install at the factory because it’s a proven and dependable design.
The Brisk II has been engineered for improved airflow and reduced vibration compared to its predecessors, offering a solid balance of cooling power and user comfort. Available in both 13,500 and 15,000 BTU models, it can be sized for almost any RV. It’s a straightforward, durable machine designed to withstand the bumps and rattles of life on the road.
While it lacks the ultra-slim profile of the Penguin II or the whisper-quiet operation of the Houghton, the Brisk II’s strength is its value and dependability. It’s a known quantity. For RVers who need a powerful, long-lasting AC without paying for premium features they don’t need, the Brisk II is a tough-to-beat, all-around performer.
GE Rooftop AC: Trusted Performance and Great Value
Experience quiet, efficient cooling with the GE Profile™ RV AC Rooftop Air Conditioner. Its low-profile design maximizes space while delivering powerful climate control for your travels.
When a household name like GE enters the RV market, it brings a reputation for reliability and engineering. The GE Rooftop AC lives up to that name, offering a fantastic option for RVers who want trusted performance without the premium price tag often associated with specialty RV brands. It’s a straightforward unit that focuses on doing one job well: cooling your rig.
The design prioritizes ease of installation and use. Its components are robust, and the controls are simple and intuitive, making it a great choice for a DIY replacement or for RVers who aren’t interested in complex digital controls. It delivers its rated BTUs effectively and provides a much-needed escape from the summer heat.
What makes the GE unit so compelling is its value proposition. It often costs less than comparable models from Dometic or Coleman while providing similar cooling power. For the budget-conscious nomad or the weekend warrior who needs a dependable AC that won’t break the bank, GE offers a smart, high-value alternative.
Key Factors for Your RV Air Conditioner Purchase
Choosing the right AC comes down to matching a unit to your specific travel style. Don’t just buy the most powerful or the most expensive one. Instead, weigh these factors to find your perfect fit.
- Cooling Power (BTUs): Are you in a 20-foot van staying on the coast (13,500 BTU is likely enough) or a 35-foot fifth wheel heading to the desert (15,000 BTU is a must)? Be realistic about your needs.
- Power Consumption: Check the running amps and, more importantly, the start-up amps. If you plan to boondock with a small generator or run on a 30-amp site, a unit with a lower draw or a built-in soft-starter (like the RecPro) is a huge advantage.
- Noise Level: How much does sound bother you? If you’re a light sleeper or work in your RV, prioritizing a quiet model like the RecPro Houghton will dramatically improve your quality of life.
- Physical Profile and Weight: Do you travel routes with low-hanging branches or worry about overall height? A low-profile model like the Dometic Penguin II is the obvious solution. Always check that your roof can support the unit’s weight.
- Extra Features: Do you camp in the shoulder seasons? A heat pump, like the option on the Furrion Chill, can extend your camping season comfortably and save propane.
Ultimately, the best RV air conditioner is the one you don’t have to think about. It’s the one that keeps you cool in the desert, runs quietly enough for you to sleep, and doesn’t trip the breaker every time you make coffee. By honestly assessing your RV, your power sources, and where you plan to roam, you can invest in a unit that will become a silent, reliable partner in your adventures.
