As an RV air condition supplier, I often get asked by customers whether they can install an RV air conditioner themselves. This is a valid question, especially for those who are handy and like to take on DIY projects. In this blog post, I'll delve into the details of self - installing an RV air conditioner, discussing the pros and cons, the necessary skills and tools, and some safety considerations.
The Appeal of Self - Installation
One of the main reasons people consider self - installing an RV air conditioner is cost. Hiring a professional to do the installation can be quite expensive. By doing it yourself, you can save a significant amount of money. Additionally, for many RV owners, the sense of accomplishment that comes with completing a DIY project is priceless. You get to know your RV inside out and gain valuable hands - on experience.
Another advantage is the flexibility it offers. You can choose to install the air conditioner at your own pace, fitting it around your schedule. There's no need to wait for a professional to be available, which can be especially beneficial if you're planning a trip soon and need the air conditioner up and running quickly.
The Challenges of Self - Installation
However, self - installation is not without its challenges. First and foremost, it requires a certain level of technical knowledge. An RV air conditioner is a complex piece of equipment that involves electrical, mechanical, and sometimes even plumbing components. If you're not familiar with these systems, it can be easy to make mistakes that could damage the air conditioner or, worse, pose a safety hazard.
For instance, improper electrical wiring can lead to short circuits, which may cause a fire. Incorrect installation of the ventilation system can reduce the efficiency of the air conditioner, leading to higher energy consumption and less effective cooling. Also, if the unit is not installed level, it may not drain properly, leading to water damage inside the RV.
Necessary Skills and Tools
To install an RV air conditioner yourself, you'll need to have a basic understanding of electrical systems. You should be comfortable working with wires, connecting terminals, and using a multimeter to test for voltage. Knowledge of basic carpentry is also helpful, as you may need to cut holes in the RV roof or install mounting brackets.
As for tools, you'll need a variety of items. A drill is essential for making holes in the roof and for attaching brackets. A screwdriver set, both flat - head and Phillips, will be used to remove and install panels and components. A saw may be required to cut ventilation ducts or to modify the roof opening. You'll also need a measuring tape to ensure accurate placement of the air conditioner, and a level to make sure it's installed correctly.
Safety Considerations
Safety should be your top priority when attempting to install an RV air conditioner. Before you start, make sure to disconnect the RV's power supply to avoid electrical shocks. Wear appropriate safety gear, such as gloves and safety glasses, to protect yourself from sharp edges and flying debris.


When working on the roof, use a sturdy ladder and take precautions to prevent falls. If you're not comfortable working at heights, it may be best to hire a professional. Also, be aware of the weight of the air conditioner. Some units can be quite heavy, and improper lifting can lead to back injuries.
Step - by - Step Installation Guide
- Choose the Right Location: The first step is to select the best location for your RV air conditioner. This is usually on the roof, near the center of the RV for even cooling. Make sure there are no obstructions, such as vents or antennas, in the area.
- Prepare the Roof: Measure and mark the area where the air conditioner will be installed. Use a saw to cut a hole in the roof according to the manufacturer's specifications. Be careful not to damage any underlying structures.
- Install the Mounting Brackets: Place the mounting brackets in the hole and secure them to the roof using screws. Make sure the brackets are level and firmly attached.
- Connect the Electrical Wiring: Follow the wiring diagram provided by the manufacturer to connect the air conditioner to the RV's electrical system. Use wire connectors to ensure a secure connection and insulate the wires to prevent short circuits.
- Install the Air Conditioner Unit: Carefully lift the air conditioner unit onto the mounting brackets and secure it in place. Connect the ventilation ducts and any other necessary components.
- Test the System: Once the installation is complete, reconnect the power supply and test the air conditioner. Check for proper cooling, airflow, and any signs of leaks.
When to Hire a Professional
If you're unsure about any aspect of the installation process, it's always a good idea to hire a professional. A professional installer has the experience and expertise to ensure that the air conditioner is installed correctly and safely. They can also troubleshoot any problems that may arise during the installation.
Some situations where you should definitely consider hiring a professional include if your RV has a complex electrical system, if you're installing a high - end or large - capacity air conditioner, or if you're not comfortable working on the roof.
