FAQ Section
Q1: What exactly is a “Duo Therm RV air conditioner”?
A1: Duo Therm was an original, well-known brand of RV air conditioners. Over time, Duo Therm was acquired by Dometic, and their RV air conditioning products are now sold under the Dometic brand. Many older RVs still have “Duo Therm” branded units, and Dometic continues to produce compatible replacement parts and modern AC units that can often replace older Duo Therm models.
Q2: How often should I service my RV AC unit?
A2: It’s generally recommended to have your RV AC unit serviced annually, ideally before the start of the hot season. This can include cleaning coils, checking electrical connections, inspecting for leaks, and ensuring the fan is operating correctly. Regular maintenance helps prevent breakdowns and improves efficiency.
Q3: What’s the difference between a ducted and non-ducted RV AC system?
A3: A ducted system distributes cool air through a series of vents hidden in the RV’s ceiling, offering more even cooling and often quieter operation since the main unit is less exposed. A non-ducted system blows air directly out of the unit located in the main living area, which is simpler but can be louder and less efficient for larger spaces.
Q4: How do I know what size (BTU) RV AC unit I need?
A4: The required BTU (British Thermal Units) depends on your RV’s size, insulation, and the climate you typically camp in. As a general rule:
* Small RVs (under 20 ft): 11,000 – 13,500 BTU
* Medium RVs (20-30 ft): 13,500 – 15,000 BTU
* Large RVs (over 30 ft) or in hot climates: 15,000 BTU or more, often requiring two AC units.
It’s always best to check your RV manufacturer’s recommendations.
Q5: Can I replace my old Duo Therm AC unit with a newer Dometic model?
A5: In most cases, yes! Dometic has designed many of its newer RV air conditioners to be direct replacements or easily compatible with older Duo Therm units. However, always double-check the mounting dimensions, electrical requirements, and whether your RV has a ducted or non-ducted system to ensure a proper fit and functionality.
Q6: What are common signs that my RV AC unit needs repair or replacement?
A6: Key indicators include:
* The unit blowing warm air instead of cold.
* Excessive noise or strange rattling sounds from the unit.
* Reduced airflow from the vents.
* Frequent tripping of circuit breakers when the AC is on.
* Visible leaks or corrosion around the unit.
* The unit simply not turning on.
Q7: Are aftermarket shrouds and fan blades worth it?
A7: Absolutely! Aftermarket shrouds, like the ICON ones reviewed, often offer superior durability and UV protection compared to original factory parts, extending the life and improving the appearance of your AC unit. Replacement fan blades, such as the Dometic compatible one we reviewed, are a cost-effective way to fix common noise issues and restore proper cooling without the expense of a full AC replacement.
