When you're traveling in your RV, comfort isn't just a luxury, it's essential. Whether you're driving through desert heat, parked at a sunny campsite, or trying to sleep through a muggy night, having the right air conditioning system can make or break your experience.
At Integrity RV Parts, we know how crucial it is to keep your rig cool and comfortable. That’s why we’ve created this comprehensive guide to help you choose the best RV air conditioner for your needs.
Why You Need an RV AC System
A reliable RV air conditioner does more than just lower the temperature. It creates a comfortable living environment no matter where your adventures take you.
Especially during summer months or in warmer regions, an AC system helps regulate interior temperatures, reduce humidity, and make the RV feel like a home away from home. It also protects your electronics, appliances, and soft furnishings from excess moisture.
Whether you're taking a quick weekend trip or embarking on a long-term road journey, an RV air conditioner helps you stay comfortable every step of the way.
Types of RV Air Conditioners
When it comes to air conditioning for Class A RVs, two main types dominate the market: rooftop air conditioners and basement air conditioners.
Rooftop units are by far the most common choice, known for their reliability and ability to efficiently cool large interiors. These units are typically mounted on top of the RV and can be either ducted, which distributes cool air evenly through ceiling vents, or non-ducted blowing air directly into the living space.
For larger, or luxury Class A motorhomes, basement air conditioners are another popular option. Installed in lower compartments, these systems offer a quieter operation and free up roof space. This makes them a great solution for RVers who want a more streamlined exterior or need clearance in height-restricted areas.
When choosing between rooftop and basement AC units, consider factors such as layout, noise preference, and how much roof space you want to preserve. Both options offer powerful cooling, but the right fit depends on your RVing lifestyle and comfort priorities.
How RV Air Conditioning Systems Work
Understanding how your RV’s air conditioning system works can help you maintain it and choose the best replacement when the time comes. Most RV AC units rely on a similar set of components: a compressor, condenser coils, evaporator coils, a fan or blower motor, and a control system.
The compressor circulates refrigerant through the coils to transfer heat from inside the RV to the outside. Meanwhile, the fan draws warm air in, cools it over the evaporator coils, and pushes it back into the living space.
Some units include built-in heat pumps, which allow them to reverse this process and provide light heating in cooler temperatures. Your AC system may also include a thermostat or digital control panel, which lets you manage temperature settings and fan speeds.
Modern systems may integrate with your RV’s smart control hub or offer remote access via mobile apps.
How Much Cooling Power Do You Need?
Choosing the right cooling capacity is one of the most important factors when selecting the right air conditioner for your RV. BTUs (British Thermal Units) are used to measure an AC unit's power.
Larger RVs typically require at least 15,000 BTUs per unit to cool the space effectively. Many class A owners opt for dual AC setups, especially in warmer climates or in longer rigs. This provides the RV with consistent multi-zone cooling throughout the cabin.
It is also important to consider your RV's insulation, ceiling height, and travel habits. If you often camp in hot and humid regions or your RV retains heat easily, choosing a higher BTU rating or upgrading to a second unit can significantly improve comfort.
Single-Zone vs. Multi-Zone Systems
Choosing between a single-zone or multi-zone air conditioning system comes down to your RV's size and how you use your interior space. Some setups feature a single 15,000 BTU unit that cools the entire cabin, which can work well for come compact or open layouts.
However, multi-zone systems are a smart choice for larger floor plans or those who want more precise temperature control. They allow you to set different temps in different areas, such as keeping the living space cooler during the day while maintaining a lower setting in the bedroom at night. This setup not only enhances comfort but also helps improve energy efficiency by cooling only where it is needed.
If your rig sees a lot of variation in climate or passenger preferences, a multi-zone system can make a noticeable difference in day-to-day comfort.
Comparing Features and Add-Ons
Today’s RV air conditioners come with a wide range of features designed to enhance performance, convenience, and efficiency. Low-profile designs are popular among RVers who want to reduce roof drag or need clearance for storage garages.
Energy-efficient models are also available and can help you make the most of limited shore power, generator capacity, or even solar systems.
Noise level is another key factor; some units are designed for quiet operation, making them ideal for use at night or in campgrounds where noise is a concern. Many newer models come with digital controls, remote access, and smart thermostat integration.
If you travel in colder seasons or encounter chilly mornings, consider an AC unit with a built-in heat pump so you can take advantage of mild heating without running a separate furnace.
Retrofitting Older RVs
Upgrading your current RV air conditioner is a smart move if your old unit is underperforming or failing altogether. When retrofitting, be sure to check compatibility with your RV’s existing ductwork, roof openings, and electrical system. Most rooftop AC units fit into a standard 14" x 14" opening, but it’s always worth measuring before ordering a replacement. Some upgrades may require transition or adapter kits, especially if you're switching brands or moving from a non-ducted to a ducted system.
Installation Tips and Considerations
Installing a new RV air conditioner isn’t always a simple plug-and-play process. You’ll need to ensure that your unit matches your roof cutout, seals tightly to prevent leaks, and is compatible with your electrical system, whether you’re running 30-amp or 50-amp service. Pay close attention to sealants and mounting hardware to avoid moisture intrusion, and always follow manufacturer instructions closely.
If you're not comfortable with electrical wiring or roof installation, we recommend working with a certified RV technician. A professional install ensures the job is done safely and correctly and gives you peace of mind before your next trip.
How to Choose the Best RV Air Conditioner
When you're ready to buy, start by evaluating your needs. Consider the size of your RV, the climate where you’ll be camping, and whether your travels typically involve hookups, generator power, or off-grid living.
Think about noise levels, energy efficiency, smart features, and whether you’ll need heating as well as cooling. Are you replacing an old unit, or installing something brand new? Is your RV pre-wired for a second AC unit? These are all important questions to ask before purchasing.

Frequently Asked Questions About RV Air Conditioners
Can I run my RV air conditioner on solar power?
Yes, but it’s not easy. RV AC units draw a significant amount of power, so you’ll need a robust solar setup, large battery bank, and a high-capacity inverter to run them effectively.
How long should an RV AC unit last?
With proper maintenance, most RV air conditioners last between 5 to 10 years. Regularly cleaning filters, inspecting coils, and checking for leaks can extend the life of your unit.
Can I install a second air conditioner in my RV?
Many larger RVs come pre-wired for a second unit. If yours isn’t, installation is still possible but may require additional wiring and electrical upgrades.
Is it worth upgrading to a more powerful AC unit?
If your current unit struggles to cool your space, especially in extreme heat, upgrading to a higher BTU model can significantly improve your comfort on the road.
