How to Install an RV Air Conditioner: A Step-by-Step Guide
When the summer heat hits, being able to stay cool in the comfort of your RV is one of the great things about traveling. If you’re planning to install an air conditioner for your RV to beat the heat, you’ve come to the right place. Although installing an air conditioner may seem like a challenging task, for most DIY enthusiasts, installing an RV air conditioner is a completely manageable task with the right tools, time, and preparation.
In this guide, we’ll walk you through the entire process of installing an RV air conditioner, from choosing the right unit to the final installation steps. By the end, you’ll have a clear understanding of each step and be well-equipped to complete this project on your own.
- Choose the Right RV Air Conditioner
Before you start installing, it’s crucial to choose an air conditioner that’s right for your RV. There are many types of RV air conditioners on the market, and choosing the right one depends on factors like the size of your RV, the climate you’re traveling in, and your power needs.
Types of RV air conditioners:
Rooftop Air Conditioners
This is the most common type of RV air conditioner, installed on the roof of the RV, and usually provides cooling for medium to large RVs. Rooftop air conditioners usually require more power support, but are better in cooling effect and efficiency.
Portable Air Conditioners
Although portable air conditioners are not as powerful as rooftop air conditioners, they are a more economical choice for small RVs or those who need a temporary cooling solution. Portable air conditioners usually require a window vent to exhaust hot air.
Split Air Conditioners
This system has an outdoor compressor and an indoor air conditioning processor, and is a quieter and more energy-efficient option for larger RVs. It’s relatively complicated to install this type of air conditioner, but in some cases, it’s worth the investment.
Colku’s air conditioning products cover rooftop air conditioners, portable air conditioners, and split air conditioners, and owners can choose the right air conditioner according to actual conditions. For most RV owners, a rooftop air conditioner is the best choice, especially if you plan to use your RV for a long time or your RV is large. Common RV air conditioners generally range between 13,500 and 15,000 BTU, with higher BTUs suitable for larger RVs.
- Prepare Tools and Materials
Before you start the installation, first prepare the tools and materials you need. Here are the tools you may need for rooftop RV air conditioner installation:
- Air conditioner unit (make sure it is designed for RV)
- Electric drill (with various drill bits)
- Screwdriver (manual or electric)
- Tape measure
- Roof sealing tape or butyl tape
- Roof sealant (silicone-based or RV-specific)
- Screws and bolts
- Socket wrench and ratchet wrench
- Assistant (it is best to have help when installing the air conditioner unit)
- Ladder (for climbing onto the roof)
- Work gloves (to protect your hands)
Make sure you have all the necessary accessories provided with the air conditioner, including mounting brackets, vent ducts, and wiring instructions. Check the user manual provided by the manufacturer to make sure you are using all the necessary parts. If you purchase an air conditioner from colku, we will provide you with online installation guidance services (video or picture instructions)。
- Prepare the RV for Installation
Safety First:
Make sure the RV is parked on smooth, stable ground with the engine off. Disconnect the RV from power during the installation process to avoid electrical accidents.
Measure and Mark the Installation Area:
Measure the roof of the RV to make sure you have enough space to install the air conditioner. Typically, the roof opening required for the air conditioner is about 14" x 14" (35.5cm x 35.5cm), although some models may require a slightly larger opening.
Once you have determined the location, mark where the air conditioner will be installed. Make sure it is centered and there are no obstructions around it that may affect the installation, such as vents, satellite dishes, or other roof parts.
Remove Roof Covering:
If your RV already has a vent or other air conditioning unit, remove the existing roof covering or vent first. You will need to clean and prepare the roof area for the installation of the new air conditioning unit.
- Install the Rooftop AC Unit
Step 1: Create the Roof Opening
If you are replacing an old vent, you may be able to use the existing opening. But if you are installing an AC unit for the first time, you will need to cut a new hole in the RV roof. Use a jigsaw or reciprocating saw to carefully cut the opening needed for the AC unit. Wear protective glasses and gloves when doing this to ensure safety.
Step 2: Install the Bracket
Place the bracket (or mount) over the opening you just cut. Most AC units come with brackets that hold the unit to the roof. Use a tape measure to make sure the bracket is centered and level.
Once the bracket is in place, use a power drill to drill holes in the bracket, ready to attach it to the roof. Double-check that the holes align with the mounting points on the AC unit.
Step 3: Install the AC Unit
Get a helper to help you lift the AC unit to the roof. Installing the AC unit is the most challenging part, as RV AC units are usually heavy, often weighing more than 80 pounds.
Carefully lower the AC unit into the opening and make sure it sits securely on the bracket. The AC unit should be able to sit securely on the bracket. Once you have confirmed the location, make sure to align the mounting holes of the bracket and the unit.
Fasten the unit to the bracket using screws. Tighten the screws using a socket wrench or screwdriver to ensure the unit is securely mounted.
Step 4: Seal the unit
To prevent water leaks, apply RV-specific sealant to the edges of the unit. You can also use butyl tape or roof sealing tape to ensure a waterproof effect. Carefully press the tape into the gap between the unit and the roof to ensure a tight seal.
Step 5: Connect the ducts and wiring
The air conditioner usually comes with ducts for indoor use, which should be connected to the air conditioner processor inside the RV. Use the provided clips and fasteners to secure the ducts. Make sure the ducts are installed in a way that allows air to flow smoothly for effective cooling.
Connect the wires according to the instructions provided by the manufacturer. Usually, you need to connect the air conditioner unit to the RV's 12V or 120V power system, depending on the power requirements of the air conditioner. If you are not sure how to handle the electrical connections, it is recommended to call in a professional for help.
- Test the AC unit
Once the AC unit is installed and wired, plug in the RV and turn on the AC unit. Check that the AC unit is cooling properly and that all functions, such as temperature control, fan speed, and cooling mode, are functioning properly.
Inspect the edges around the AC unit carefully for any signs of leaks. If you notice any gaps or leaks, apply additional sealant to ensure the unit is completely sealed.
After confirming that the air conditioner is working properly, tidy up the installation site. Clear any debris from the roof and check the interior again to make sure everything is secure.
