Frequently Asked Questions (FAQ)
What is a ducted RV air conditioner system?
A ducted RV air conditioner system works much like the central air in your home. Instead of the unit blowing air directly into the main living space, it distributes cooled air through a series of vents located in the ceiling or walls of your RV. This provides more even cooling throughout multiple rooms or zones, reducing hot spots and improving overall comfort compared to a non-ducted system.
Why choose a Coleman RV AC unit for my ducted system?
Coleman-Mach has a long-standing reputation for manufacturing durable, reliable, and efficient RV air conditioners. They are known for their robust construction, powerful cooling capabilities, and wide availability of parts and service. Many RV manufacturers install Coleman-Mach units as original equipment, so they’re often a natural fit for existing ducted systems.
How do I know what BTU rating my RV needs?
Generally, you’ll need around 1,000 BTUs per linear foot of your RV. For example, a 30-foot RV might need a 30,000 BTU capacity, often achieved with two 15,000 BTU units or one 15,000 BTU and one 13,500 BTU. Factors like insulation quality, window surface area, and travel climate also play a role. When in doubt, it’s often better to have slightly more cooling power than not enough.
Can I install a Coleman ducted RV AC unit myself?
While some experienced DIYers might tackle an RV AC installation, it often involves working with electrical wiring, sealing the unit to the roof, and ensuring proper connection to the ducted system. For safety and to ensure proper operation (and warranty validity), professional installation is often recommended, especially if you’re not comfortable with electrical work or roof modifications.
What’s the main difference between ducted and non-ducted RV AC units?
The primary difference lies in air distribution. A non-ducted unit blows air directly from the rooftop unit into the RV’s main cabin via a ceiling assembly. A ducted unit, on the other hand, channels the cooled air through an internal ductwork system to multiple vents throughout the RV, offering more even cooling and typically quieter operation in the main living area since the main fan noise is more centralized at the unit itself.
How do I maintain my Coleman ducted RV AC system?
Regular maintenance is key! This includes checking and cleaning the air filters (usually found in your ceiling plenum or return air vents) every month during active use, cleaning the evaporator and condenser coils annually, inspecting electrical connections, and ensuring the roof gasket is properly sealed to prevent leaks. Also, check for debris on the rooftop unit that could obstruct airflow.
Is a heat pump feature worth it for a Coleman RV AC?
A heat pump is a fantastic feature for extending your camping season. Instead of relying solely on a furnace or electric space heater, a heat pump can provide efficient heating down to certain outside temperatures (usually around 40-45°F or 5-7°C) by reversing the refrigeration cycle. This saves propane and provides comfortable, even heat, making it a valuable addition for shoulder season travel.
