Frequently Asked Questions (FAQ)

Q1: What BTU size Dometic RV air conditioner do I need for my RV?
A1: The ideal BTU (British Thermal Unit) size depends mainly on the length and insulation of your RV. A general guideline is:
– Small RVs (under 20 ft): 10,000 – 11,000 BTU
– Medium RVs (20-30 ft): 13,500 BTU
– Large RVs (over 30 ft) or those in very hot climates: 15,000 BTU (or even two units for very large rigs).
It’s always best to check your RV manufacturer’s recommendations.

Q2: What’s the difference between ducted and non-ducted RV AC systems?
A2:
– Ducted systems distribute cool air through a series of vents in your RV’s ceiling, providing more even cooling throughout the living space. They typically require a specific air distribution box (ADB).
– Non-ducted systems blow cool air directly from the unit, usually through a grille located underneath the rooftop AC. These are often easier to install and popular in smaller RVs or as secondary units.

Q3: How often should I clean my Dometic RV AC filter?
A3: It’s a good practice to check and clean your RV AC filter monthly, especially during heavy use. Dirty filters restrict airflow, reduce efficiency, and can lead to premature wear on your unit. Most Dometic filters are easily removable for washing.

Q4: Are Dometic RV AC units noisy?
A4: While all air conditioners produce some noise, Dometic has made significant strides in reducing operational sound. Newer models, like the FreshJet 3 Series, are designed for quieter performance, often boasting 4dB reductions in noise compared to older models or competitors. Factors like proper installation and maintenance also play a role in noise levels.

Q5: What does “backwards compatible” mean for Dometic RV air conditioners?
A5: “Backwards compatible” means that a new Dometic AC unit can be installed using the existing air distribution box (ADB) or thermostat from an older Dometic unit, or sometimes even a competitor’s unit. This makes upgrading much simpler, as you don’t necessarily have to replace the entire internal setup, saving time and money.

Q6: What are E-coated evaporator coils, and why are they important?
A6: E-coated evaporator coils feature a flexible epoxy polymer coating that is specifically engineered for HVAC heat transfer coils. This revolutionary design provides exceptional flexibility, durability, and most importantly, superior corrosion resistance. It helps protect the coils from environmental factors, extending the lifespan and maintaining the efficiency of your Dometic RV air conditioner, particularly in humid or coastal areas.

Q7: How important is a low-profile design for an RV air conditioner?
A7: A low-profile design, like that of the Dometic Penguin II, offers several benefits. It reduces the overall height of your RV, which can be crucial for clearing low bridges, tunnels, or garage entrances. It also improves aerodynamics, reducing wind resistance during travel, which can lead to better fuel efficiency and a quieter ride. Aesthetically, many RVers prefer the sleeker look of a low-profile unit.

Q8: Can I install a Dometic RV air conditioner myself?
A8: While some Dometic units are designed for easier installation (especially those that are lightweight and backwards compatible), installing an RV air conditioner typically involves working with electrical systems, sealing the roof opening, and safely lifting a heavy unit onto the roof. If you have experience with RV maintenance and electrical work, a DIY installation might be possible. However, for most people, professional installation is recommended to ensure safety, proper sealing, and optimal performance, especially to maintain warranties.
