Beat the heat with the perfect RV AC unit.
While most RV owners don’t have control over what kind of AC unit gets placed into their rig during the manufacturing process, there is usually an option to upgrade at purchase or make a change later during ownership.
Regardless of the reason you’re in the market for an AC unit for your RV, we’ve rounded up some factors to consider when selecting the best option. Keep these considerations in mind to ensure a comfortable interior no matter where your travels take you.
Understanding RV Limitations
Like any upgrade or modification that you consider for your RV, the decision will be largely dependent on what your camper can actually handle and/or accommodate. Some parameters that could limit your options include the square footage (size), power source, and wattage.
RV Size & BTUs
The most common sizes for RV air conditioners are 13,500 BTUs and 15,000 BTUs. Generally, the higher the BTU, the quicker your rig will cool down. Higher BTU air conditioners are especially effective for quickly and efficiently cooling larger RVs, such as fifth wheels and coaches. In fact, very large coaches often support two AC units to evenly distribute cooling.
On the flip side, if you have a smaller coach or don’t plan on spending much time camping in really hot climates, then opting for an AC with lower BTU (10,000 BTU or fewer) can save you money and power.
It’s important to remember that factors such as insulation, ambient temperature, and airflow within the RV also impact how effective your AC will be.
AC Size & Wattage
To determine the appropriate size and number of AC units for your RV, it's crucial to know your power service: 30- or 50-amp. RV air conditioners typically range from 500 to 2700 watts, with most using between 700 and 1500 watts.
For example, a 13,500 BTU AC unit averages around 1350 watts. A 30-amp service provides approximately 3600 watts of power, which could easily run your AC, refrigerator, and electric water heater simultaneously if using a 13,500 BTU unit. However, if you had a bigger AC unit -- say 15,000 BTU -- or two AC units, then 30-amp service may not be enough to successfully run all your RV appliances without tripping the breaker. It's also worth noting that AC units require higher wattage during startup before stabilizing to their running wattage.
Different Types of AC Units
RV AC units come in various shapes and sizes, each offering unique advantages.
Profile
When making your selection, first consider whether you prefer a low-profile or regular unit. Regular units have a higher profile and are generally more powerful than most low-profile units. However, low-profile ACs are lighter in weight and provide better clearance when passing under bridges and overhangs.
Ducted vs Ductless
Another thing to consider when purchasing an AC unit for your RV is whether you have a ducted or ductless system. Ducted units, common in motorhomes, feature multiple ceiling ducts, making it easier to distribute air evenly throughout the coach. Ductless units, by contrast, blow air directly from the unit through lower vents, offering flexibility in installation.
Single vs Multizone
Certain AC units also provide multizone systems, allowing you to control more than one RV AC unit with a single thermostat. These are more suitable for larger RVs, and generally feature electronic controls with automatic restart and shutoff functions.
Another way to achieve a multizone setup in your RV is to install a split-system AC unit. Offering a flexible cooling option, split systems consist of two components: an indoor unit and an outdoor unit, connected by refrigerant lines. The smaller indoor component absorbs heat, while the bulkier outdoor part cools and pumps cold air into the indoor unit. Split-system units help free up valuable interior space, and can offer potentially higher energy efficiency than traditional setups; however, they may require a more complex installation.
Portable vs Built-In
A portable AC unit can be handy if you don’t have a built-in AC unit and don’t want to install one. These temporary cooling solutions offer convenience without the need for installation, meaning you can tote one along and cool down whatever space you’re in quickly and efficiently. It’s important to note, however, that portable AC units typically have lower cooling capacities compared to built-in units.
Dual-Usage
For those who want to take care of all their RV cooling and heating needs in one fell swoop, dual-usage AC units offer comprehensive climate control. These units, which include a heat pump, can function as both heaters and air conditioners, providing year-round comfort.
The only downfall to a dual usage is that the heater only works well to a certain temperature range, while a true furnace can keep you warm in even the harshest cold weather. Therefore, if you like to enjoy winter camping in some tough environments, supplementing with additional heating sources may be necessary.
Some of the biggest names in RV air conditioners are Coleman, Dometic, Furrion, and Webasto, all of which can be found right here at Parts Via.
AC Features to Consider
Manufacturers often offer their AC units in series, with each one offering different bells and whistles. The additional features can help customize your setup, and ultimately influence your decision.
For example, if you like to get off the grid, then you may want to consider an AC unit with a specially-designed rugged construction, like the Coleman-Mach Roughneck Series. Engineered for boondockers and off-road enthusiasts, the Roughneck Series offers high-efficiency cooling power plus a fortified interior construction to handle rough, off-road, and heavy industrial vehicle applications.
If whisper-quiet operation is more important to you, then look for a unit with lower decibel levels like the Furrion Chill. At 60dB, it’s the quietest model on the market. Part of that is due to the dual-fan technology, which Furrion says is more efficient and up to 50% quieter than single-fan systems because the setup doesn’t need to work as hard to cool the interior.
Other features to consider are Bluetooth compatibility for easy remote operation, air purifier functionality for a fresher cabin, and power-saving technology for more efficient performance.
Additional Accessories
To enhance the performance of your RV air conditioner, consider investing in accessories that offer both protection and improved functionality.
An essential accessory is an RV AC air filter, which safeguards the unit from dust, dirt, pet dander, and other contaminants that can lead to clogging and faster wear and tear. By capturing these particles, the filter not only prolongs the lifespan of your AC unit but also improves air quality inside your RV, reducing allergens and inhibiting mold growth. Brands like Eramco and RV Air both offer high-quality filters available through Parts Via.
Additionally, an RV AC unit shroud, or cover, is invaluable for protecting your unit while on the road, at the campsite, and during storage. Shielding against UV light damage, debris, nesting animals, and harsh weather conditions, they help prolong the lifespan of your AC unit. Brands like Maxxair and Icon offer durable shrouds made from molded, high-impact UV-resistant material, ensuring reliable protection for your RV AC unit.
Signs It’s Time for a New AC
RV AC units typically have a long lifespan of 10-15 years, but sometimes earlier replacement is warranted. If your RV’s AC unit is exhibiting any of the following signs, it might be time for a change:
- Excessive noise
- Unpleasant odor
- Slow performance
- Frozen coils
- Overheating problems
- Uneven temperatures
- Increased energy usage
- High humidity levels
Whether you’re in need of a new AC unit due to these issues or simply seeking an upgrade, keep the above factors in mind when purchasing, and check out the wide selection of AC units and accessories available here on Parts Via to find the perfect fit for your RV.
