Keeping cool during your RV adventures is essential, especially when traveling through hot climates or during summer months. Luckily we show you how to install an RV air conditioner properly.
Whether you’re replacing an old unit or upgrading to a more efficient model, installing an RV air conditioner can be a relatively straightforward process if you know what you are doing.
If you don’t, you can follow advice from van lifers who have done van conversions and use their experience to get it right. That’s what are are sharing below, having gone through the process.
Preparing Your Van For New Air Conditioner
Before beginning the installation, ensure your RV’s roof can support your weight by laying down wooden planks to distribute the load.
This precaution not only protects the roof but also minimizes the risk of scratches and ensures you don’t encounter problems later on.
Removing The Old Air Conditioning Unit
Start by disconnecting the power supply to the old AC unit, whether than is a full unit or a 12V air conditioning system.
Carefully remove the mounting bolts and detach the wiring. Use a scraper to clean off any old adhesive, as a proper seal is crucial for the new installation.
Lifting the New AC Air Conditioning Unit In Place On Your Van
Getting the new unit onto the roof can be challenging due to its weight, typically ranging from 60 to 100 pounds.
If possible, use mechanical assistance like a crane or forklift. Alternatively, create a pulley system with ropes and enlist help to safely lift the unit.
Keep the AC in its original packaging with added protection to prevent damage.
Installation Process For Air Conditioning Unit On An RV
Positioning: Carefully slide the new AC into the roof opening, ensuring a snug fit. If necessary, adjust the opening size to accommodate the new unit.
Securing: Place the gasket correctly and ensure the AC frame is flush with the ceiling. Fasten the unit using the mounting bolts.
Wiring: Locate the junction box and connect the wires according to their color codes. Double-check all connections to prevent hazards.
Final Steps: Reattach all covers and shrouds, then reconnect the power supply.
Testing: Run the AC on all settings to verify proper installation and functionality.
What Are The Most Common Mistakes To Avoid When Installing An RV AC?
Some of the most common mistakes to avoid when installing an RV air conditioner include choosing the wrong size AC unit in the first place.
Installing an AC that is too large or too small for your RV can lead to inefficiency, short-cycling, or overworking the unit. You need the right size AC unit.
Failing to properly set up the drainage can result in water damage to your RV, including deteriorated drywall, backed-up pipes, and mold growth.
The placement of the thermostat can affect the AC’s performance, so it’s important to choose an appropriate spot. Improper placement of vents can also lead to inadequate airflow throughout the RV.
Overcharging the system with refrigerant can damage the entire air conditioning unit and should be avoiding and failing to seal holes and clean up wiring can restrict airflow and reduce efficiency.
Not providing enough clearance for the condenser, which needs at least two feet of clearance on all sides to operate efficiently is another important consideration.
Maintenance Tips For RV Air Conditioning
To keep your new RV AC in top condition, cover the unit when not in use to keep it clean and regularly oil the fan to reduce noise and ensure smooth operation.
It’s important to maintain proper airflow in your RV to prevent freezing in humid conditions. We recommend cleaning the AC filter monthly and replacing it annually.
You can also consider installing a thermostat for energy conservation and convenience.
By following these steps and maintenance tips, you can enjoy a cool and comfortable RV experience for years to come.
How Can I Properly Maintain The Drainage System For My RV AC?
To properly maintain the drainage system for your RV air conditioner, follow these key steps:
Locate the AC drain line: Find where the drain line exits your RV, typically along the exterior underneath the vehicle.
Perform regular checks: Routinely inspect the drain line for signs of blockage, especially before trips. Look for stagnant water or moisture around the AC unit and drain pan.
Clear blockages: Use compressed air to blow through the drain line and dislodge minor clogs.
Flush the line: Periodically flush the drain line with a vinegar and water solution. This natural cleaner helps kill mold and mildew without damaging AC components.
Clean the drain pan: Use a wet-dry vacuum to remove debris and water from the drain pan. You can also use the vacuum hose to clear the end of the drain line.
Check drain holes: Regularly inspect drain holes for blockages and clear them out with a wire or compressed air.
Visual inspection: Use a flashlight to look inside the drain for obvious blockages like leaves, dirt, or insect nests. Gently remove these obstructions if possible.
Use specialized tools: For stubborn clogs, use a long, flexible wire brush or a specialized AC drain line cleaner. Insert the brush gently and push it through to remove buildup.
Avoid harsh chemicals: When cleaning, refrain from using harsh chemicals that could damage the pipes or harm the environment.
Final flush: After clearing any blockages, flush the line with clean water to ensure it’s fully open. Use a small funnel if needed to guide water directly into the drain.
