RV Air Conditioners

What is an RV Air Conditioner?

An RV air conditioner is a specially designed cooling unit that can be installed in an RV to regulate temperature and humidity inside the living space. These units are similar to traditional home air conditioners but are compact and designed to withstand the vibrations and environmental conditions that come with being on the road.

Most RV air conditioners are either rooftop-mounted or portable units, with rooftop units being the most common. They use a combination of refrigerant and air circulation to cool the air and reduce humidity, keeping the interior comfortable even during peak summer months.

Why You Need an RV Air Conditioner

Traveling and camping in an RV is a fantastic way to explore the great outdoors, but the inside of an RV can become uncomfortably warm, especially during summer. Even in mild weather, an RV can quickly heat up due to its compact size and exposure to direct sunlight. Here’s why an RV air conditioner is essential:

• Comfort: An RV air conditioner allows you to relax, sleep, and cook in comfort, even when temperatures outside are high.
• Health and Safety: High temperatures in a confined space can lead to dehydration, heat exhaustion, and other health issues. An air conditioner helps to keep temperatures at a safe and comfortable level.
• Protecting Your Belongings: Many items inside your RV, from electronics to food, can be affected by heat. An air conditioner helps protect your valuables by maintaining a stable environment.
• Better Sleep: Cooler temperatures improve sleep quality, so an air conditioner can make a significant difference in helping you feel rested and energized for your travels.

Types of RV Air Conditioners

There are several types of RV air conditioners to choose from, each with its own advantages. Understanding the different types can help you make an informed decision based on your RV’s size, layout, and cooling needs.

1. Rooftop RV Air Conditioners

Rooftop air conditioners are the most common type of RV air conditioner. These units are mounted on the roof of the RV and work by pulling in warm air from the RV, cooling it with refrigerant, and then releasing the cooled air back into the interior.

Pros:

• Space-Saving Design: Roof-mounted units don’t take up any interior space, which is essential in an RV where space is limited.
• Powerful Cooling: These units are typically more powerful than portable options and can cool down larger RVs more efficiently.
• Multiple Options: Rooftop units are available in single-zone and dual-zone models, allowing you to cool different areas of your RV.

Cons:

• Complex Installation: Rooftop units require installation and may need reinforcement of the roof for support.
• Exterior Exposure: Because they are mounted on the roof, these units are exposed to the elements and may wear out faster than indoor units.

2. Portable RV Air Conditioners

Portable air conditioners are self-contained units that can be placed inside your RV. These units often sit on the floor and require a vent hose to be connected to a window or external opening to expel hot air outside.

Pros:

• Easy to Install: No complicated installation is required. Simply plug it in and connect the vent hose to an exterior window.
• Flexible Placement: You can move a portable air conditioner to different areas of your RV as needed.
• Affordable: Portable units tend to be less expensive than rooftop models.

Cons:

• Takes Up Interior Space: Portable units take up floor space inside the RV, which can be inconvenient.
• Limited Power: Portable air conditioners may not be as powerful as rooftop units, so they’re better suited for smaller RVs or moderate climates.

3. Window-Mounted RV Air Conditioners

Window-mounted air conditioners can be installed in an RV window, much like in a traditional home. These units are compact, making them ideal for smaller RVs or camper vans.

Pros:

• Easy Installation: These units are relatively easy to install in a window opening.
• Affordable Option: Window-mounted units are often more affordable than rooftop air conditioners.
• No Roof Access Required: Ideal for RVs without reinforced roofs.

Cons:

• Reduces Natural Light: Installing a unit in a window can block natural light and views.
• Limited to Window Size: You need a compatible window for installation, which can limit options.

4. Under-Bench or Basement RV Air Conditioners

Under-bench air conditioners are installed in the lower compartments or basement areas of larger RVs. These units are less common but offer an effective way to cool your RV without using valuable roof or floor space.

Pros:

• Space Efficient: Keeps the air conditioning unit out of sight and out of the way.
• Even Cooling: Provides an even distribution of cool air, especially in larger RVs.

Cons:

• Higher Cost: These units are often more expensive than other types of RV air conditioners.
• Installation Complexity: Requires professional installation, which can add to the overall cost.

Key Features to Consider in an RV Air Conditioner

When selecting an RV air conditioner, there are several key features to keep in mind to ensure you’re choosing the best unit for your needs.

1. BTU Rating

BTU, or British Thermal Unit, is a measure of an air conditioner’s cooling capacity. The higher the BTU rating, the more powerful the unit is. For most RVs, a unit with 13,500 BTUs is sufficient, but larger RVs or those in extremely hot climates may require a unit with 15,000 BTUs or more.

2. Energy Efficiency

Energy efficiency is crucial, especially if you plan to run the air conditioner on battery power or a generator. Look for units that are designed to use minimal power while still delivering effective cooling. Some models have an Energy Efficiency Ratio (EER) rating, which can help you compare energy usage across units.

3. Noise Level

A noisy air conditioner can disrupt sleep and relaxation. Look for units that are specifically designed to operate quietly. Units with sound-dampening technology or those that advertise lower decibel levels are good options for quieter cooling.

4. Thermostat Control

A built-in thermostat allows you to set and maintain a specific temperature in your RV, making it easier to keep the environment comfortable. Some RV air conditioners come with digital thermostats, while others may have basic manual controls.

5. Heating Option

Many RV air conditioners also include a heat pump or heating option, allowing you to use the same unit to provide both cooling and heating. This can be a convenient feature if you plan to travel in colder climates or during the fall and winter months.

6. Compact and Lightweight Design

Weight and size are essential factors to consider, especially if you’re installing a rooftop unit. A lightweight model is easier to install and puts less strain on your RV’s roof. Additionally, compact models are less intrusive and blend better with your RV’s design.

7. Compatibility with Power Sources

Some RV air conditioners require 120V power to operate, while others are compatible with 12V or 24V systems, which can run off the RV’s battery. Be sure to choose a unit that’s compatible with your RV’s power setup. If you plan to use solar power or a generator, check that the air conditioner is compatible with those power sources as well.

8. Remote Control and Smart Features

Some air conditioners come with remote controls, allowing you to adjust settings from anywhere in the RV. Others offer smart features, such as Wi-Fi compatibility, which allows you to control the temperature and settings from your smartphone. These features can add convenience to your travels.

Installation Tips for RV Air Conditioners

Installing an RV air conditioner requires a few essential steps to ensure proper function and safety. Here’s a general overview of the installation process for rooftop units:

1. Measure and Prepare the Roof Opening

Most rooftop air conditioners require a 14x14-inch opening. If you’re replacing an old unit, you can use the existing opening. If not, you’ll need to carefully measure and cut an opening, making sure to reinforce the roof if necessary.

2. Seal the Roof Opening

Before installing the unit, apply a sealant around the edges of the opening to prevent leaks. A waterproof seal is essential for protecting your RV’s roof and interior.

3. Position and Secure the Unit

Place the air conditioner unit over the opening, ensuring it’s aligned properly. Use bolts or screws to secure it in place. Most units come with a gasket that helps create a secure seal between the unit and the roof.

4. Connect the Electrical Wiring

Carefully connect the wiring from the air conditioner to your RV’s electrical system. Make sure to follow the manufacturer’s instructions or seek the help of a professional electrician if needed.

5. Test the Unit

Once installed, test the air conditioner to ensure it’s working correctly. Check for any unusual noises, and ensure that cool air is being circulated evenly throughout the RV.

Maintenance Tips to Keep Your RV Air Conditioner Running Smoothly

Regular maintenance is essential for keeping your RV air conditioner in top shape. Here are some tips to help extend the life of your unit and maintain optimal performance:

1. Clean or Replace Filters Regularly

Most RV air conditioners have a filter that captures dust and debris. Clean or replace the filter regularly, especially during peak usage, to ensure proper airflow and cooling efficiency.

2. Inspect and Clean Coils

The evaporator and condenser coils can accumulate dirt over time, which reduces efficiency. Periodically check these coils and clean them with a soft brush or a coil cleaner.

3. Check for Leaks and Seal Damage

Inspect the seals around the air conditioner, especially on rooftop units. If you notice any gaps or leaks, apply additional sealant to prevent water from seeping into the RV.

4. Run the Unit Regularly

Even if you’re not using the RV, run the air conditioner occasionally to keep the internal components lubricated and prevent dust buildup.

5. Keep Vents and Fans Clear

Ensure that all air vents and fans are free of obstructions. Blocked vents can reduce airflow and make the air conditioner work harder, leading to increased wear and tear.
