Direct and redirect RV air conditioner airflow with purpose-built diverters. This guide highlights five top options that help campers reduce hot spots, improve cooling efficiency, and fit popular RV A/C vents. The best pick depends on your roof unit (Furrion, Coleman Mach, or Dometic-compatible setups) and whether you need single or dual-output airflow control. Each option is evaluated for best use cases, installation ease, and practical limitations.
| Product | Best For | Key Benefit |
|---|---|---|
| Air Conditioner Diverter for Furrion RV (Dual Output) | Furrion vent users needing dual-output control | Directs side airflow to reduce hot spots and boost cooling |
| Air Conditioner Diverter for Furrion RV (Single Output) | Furrion vent users needing single-output control | Simple peel-and-stick, targeted airflow |
| Air Conditioner Diverter for Furrion RV (Dual Output) — Another Model | Additional Furrion setup or backup | Same peel-and-stick, dual-output flexibility |
| KoolRV for Coleman Mach 1, 3, 10, 15 & Q (Not Universal) | Coleman Mach ducted roof units | Verified compatibility with select Coleman Mach models |
| DIY RV Air Conditioning Vent Channel Kit | Dometic/Other with ducted options (minor mods) | Vent routing improvements and improved airflow with DIY install |
Air Conditioner Diverter for Furrion RV — Dual Output
The dual-output diverter is designed to redirect the Furrion RV AC vent’s side airflow, improving circulation and cooling efficiency. It’s engineered for a precise vent opening (4.13″ x 9.45″) and is intended to reduce hot spots while freezing the air distribution more evenly. Best for RV owners who want targeted cooling on two directions without holes or tools. The peel-and-stick installation avoids drilling or hardware.
Best for: RV owners with Furrion systems needing stronger, dual-side airflow control. This model is chosen for its compatibility and fast installation. Limitation: the adhesive-backed design may depend on vent texture and roof conditions for long-term adhesion.
Air Conditioner Diverter for Furrion RV — Single Output
This single-output diverter focuses airflow in one direction on Furrion vents, helping reduce warm zones and improve overall comfort in smaller spaces or when a single side-directed breeze is preferred. Installation is peel-and-stick and tool-free, designed for quick setup with minimal disruption to the roof.
Best for: Campers needing straightforward sideward redirect on Furrion vents. Caution: single-output may offer less flexibility in very large or irregular spaces.
Air Conditioner Diverter for Furrion RV — Dual Output (Another Model)
Designed for Furrion roof units, this dual-output diverter provides flexible airflow redirection to combat hot spots and improve air distribution. It uses a strong adhesive backing for quick, tool-free mounting, making it a practical upgrade for existing Furrion installations.
Best for: Furrion campers needing reliable dual-output airflow. Limitation: long-term adhesion may vary by surface cleanliness and weather exposure.
KoolRV for Coleman Mach 1, 3, 10, 15 & Q — Not Universal
This version is tailored for Coleman Mach 1, 3, 15, and Q ducted rooftop RV air conditioners. It is not universal and excludes Mach 8, Dometic, Furrion, GE, or non-ducted systems. It includes guidance for compatibility and installation support. The product is best for users with compatible Coleman Mach ducted systems seeking enhanced airflow control.
Best for: Coleman Mach ducted setups where fit verification is confirmed. Limitation: not compatible with Mach 8 or non-ducted systems; verify model before ordering.
DIY RV Air Conditioning Vent Channel Kit
This foam-channeled kit aims to guide airflow through existing ducts by reducing turbulence and directing more air toward desired ducts. It’s designed for compatibility with Dometic Brisk Air 2, Dometic EVO, Blizzard models, and some Coleman variants with minor modifications. The kit includes aluminum foil tape for installation support. It is best for DIY enthusiasts comfortable with minor modifications.
Best for: DIY installers seeking a customizable airflow upgrade for compatible systems. Limitation: installation may require modification and testing for optimal performance in non-listed models.
Buying Guide: Key Considerations and Quick Comparisons
- System compatibility: Identify your RV A/C unit brand and model (Furrion, Coleman Mach, Dometic, etc.) to choose the right diverter or kit. Some products specify single vs. dual outputs or ducted vs. non-ducted configurations.
- Aim of airflow control: Decide whether you need targeted dual-output airflow to address two zones, or a single-output option for a focused breeze in one area.
- Installation approach: Peel-and-stick solutions offer tool-free, quick installs but ensure vent surfaces are clean and dry for lasting adhesion. Some kits require minor modifications or support from customer service for fitment.
- Physical dimensions: Compare vent opening sizes and overall product dimensions to ensure the diverter fits without obstructing vent operation.
- Longevity and environment: Consider exposure to heat, sun, and humidity. Adhesive-backed diverters may perform differently over time depending on roof temperature and weather conditions.
- Backup options: If one model is not a perfect match, a second compatible diverter (or a DIY kit) can provide a complementary airflow path without a full system replacement.
Frequently Asked Questions
- What is an RV air conditioner diverter? A device that redirects or concentrates the HVAC’s side airflow to improve distribution and reduce hot spots in an RV.
- Do these diverters require tools for installation? Most listed options offer peel-and-stick installation with no drilling or tools required.
- Will a diverter work with any RV A/C unit? Not universal; check compatibility with your specific model (Furrion, Coleman Mach, Dometic, etc.).
- Can I install multiple diverters at once? Yes, for larger spaces you can use more than one diverter to direct airflow to different zones.
- Are these diverters a permanent modification? Peel-and-stick options are designed for temporary-to-moderate long-term use and can be removed with care, depending on adhesive and vent surface.
- What should I do if the adhesive doesn’t stick well? Clean the vent surface, ensure dryness, and consider alternative mounting methods or a product specifically rated for vent surfaces.
