Frequently Asked Questions About Dometic RV Air Conditioners
Getting a new Dometic air conditioner for RV is a big decision. Here are some common questions folks ask to help you feel confident in your choice.
Q1: How do I choose the right BTU size for my RV?
A: The general rule of thumb is that smaller RVs (under 20 feet) might be fine with a 10,000-11,000 BTU unit, while most medium-sized RVs (20-30 feet) typically need a 13,500 BTU unit. Larger RVs (over 30 feet), especially those with slide-outs or in very hot climates, often benefit from a 15,000 BTU unit or even multiple ACs. Factors like insulation, window size, and personal preference also play a role. It’s always best to consult your RV’s manufacturer recommendations.
Q2: What’s the difference between ducted and non-ducted RV air conditioning systems?
A: A non-ducted system typically has the AC unit directly overhead with an air distribution box (ADB) that blows cool air straight down into the living space. It’s simpler to install and common in smaller RVs. A ducted system, found in many larger RVs, distributes cool air through vents located in the ceiling, offering more even cooling throughout the entire vehicle. Dometic offers units compatible with both types.
Q3: How often should I clean or replace my RV AC filter?
A: You should check your RV AC filter every month of heavy use or every few months of light use. If it looks dirty, it’s time to clean or replace it. A clean filter is vital for maximum airflow and efficiency, and it helps prevent dust and allergens from circulating in your RV. The Dometic grille accessory reviewed above makes this process a breeze!
Q4: Are Dometic RV air conditioners noisy?
A: Dometic has made significant advancements in reducing noise levels. Models like the FreshJet 3 Series are specifically designed for quiet operation, with some offering up to 4 dB less noise than competing units. While no AC is completely silent, Dometic strives to make their units as unobtrusive as possible, ensuring you can enjoy your RV without excessive background hum.
Q5: What kind of maintenance does a Dometic RV air conditioner need?
A: Regular maintenance is key for longevity. This includes:
* Cleaning/Replacing Air Filters: As mentioned, do this regularly.
* Checking Coils: Periodically inspect evaporator and condenser coils for dirt and debris; gently clean them if needed.
* Clearing Drain Holes: Ensure the condensate drain holes are clear to prevent water backup.
* Inspecting Gaskets: Check the rooftop gasket for cracks or wear to prevent leaks.
* Tightening Mounts: Ensure the unit is securely mounted to the roof.
Refer to your specific model’s manual for detailed instructions.
Q6: Can I install a Dometic RV air conditioner myself?
A: While some experienced DIYers might tackle an RV AC installation, it generally requires electrical knowledge, working on the roof, and ensuring proper sealing to prevent leaks. If you’re not comfortable with these tasks, it’s highly recommended to have a professional RV technician install your Dometic unit to ensure safety and proper operation.
