Choosing the Right RV Air Conditioner: Your Complete Buying Guide
Keeping your RV cool on hot trips makes all the difference. Buying the right RV AC unit means looking at a few important things. This guide helps you pick the best one for your adventures.
Key Features to Look For
When you shop for an RV air conditioner, focus on these main features. They determine how well the unit cools and how long it lasts.
Cooling Capacity (BTUs)
- What it is: BTUs (British Thermal Units) measure cooling power. More BTUs mean more cooling power.
- Choosing the right size: Small trailers need 8,000 to 10,000 BTUs. Larger fifth wheels often need 15,000 BTUs or more. Always check the square footage of your RV interior.
Energy Efficiency
- Look for EER or SEER ratings: Higher Energy Efficiency Ratio (EER) or Seasonal Energy Efficiency Ratio (SEER) numbers mean the unit uses less electricity to cool the same amount of space. This saves money when running on shore power or a generator.
Noise Level
- Decibel (dB) ratings matter: RV AC units can be loud. Look for models that advertise low noise output (lower dB numbers are quieter). A quiet unit helps everyone sleep better, especially in smaller spaces.
Other Useful Features
- Heat Pump Option: Some units offer a heat pump. This provides gentle heat on cool nights without needing a separate furnace.
- Smart Controls: Modern units often have digital thermostats or Wi-Fi connectivity, letting you control the temperature from your phone.
Important Materials and Durability
The materials used affect how long your AC unit works without problems. RV units face harsh weather, so durability is key.
Casing and Housing
- UV-Resistant Plastic: The outer shell must resist strong sunlight. High-quality ABS plastic resists yellowing and cracking from UV rays.
- Corrosion Resistance: Metal components, especially coils and mounting hardware, need coatings to prevent rust. Salt air near coasts or humidity can quickly damage weak metals.
Internal Components
- Copper Coils: Copper coils transfer heat better than aluminum and last longer. Good quality units use copper tubing for efficient cooling.
Factors That Improve or Reduce Quality
Quality isn’t just about the brand; it’s about how the unit performs over time.
Factors Improving Quality:
- Strong Compressor: A reliable compressor starts quickly and runs smoothly. This ensures consistent cooling even when the outside temperature is very high.
- Good Vibration Dampening: RVs shake while driving. Units built with better internal mounting systems vibrate less when running, which reduces noise and wear and tear.
Factors Reducing Quality:
- Poor Installation: Even the best unit performs poorly if it is not installed correctly. Leaks around the roof seal cause water damage and reduce efficiency.
- Inadequate Amperage Draw: A unit that draws too many amps can trip your RV’s circuit breaker, especially when starting up. Check the startup amperage before buying.
User Experience and Use Cases
Think about how and where you use your RV. This impacts your perfect AC choice.
Camping in Extreme Heat
If you camp in the desert Southwest, you need high BTU capacity and excellent insulation in your RV. Dual-AC setups are often necessary for large RVs in these conditions.
Boondocking (Off-Grid Camping)
When running on batteries or a small generator, energy efficiency is king. Look for “low-profile” or “low-amp draw” models. These units are designed to use less power, allowing them to run longer without draining your batteries completely.
Noise Sensitivity
If you plan to camp in quiet campgrounds, look for models specifically designed for quiet operation. Sometimes, a slightly smaller, quieter unit provides a better overall experience than a very powerful, loud one.
10 Frequently Asked Questions (FAQ) About RV AC Units
Q: How do I know what size (BTU) AC unit my RV needs?
A: Measure the total interior square footage of your RV. Generally, you need about 1,000 BTUs per 100 square feet. Add extra BTUs if your RV has very dark windows or poor insulation.
Q: Can I replace my old AC unit with a bigger one?
A: Yes, often you can upgrade the BTUs. However, you must check that your RV’s electrical system (shore power cord and breaker box) can handle the extra power draw of the larger unit.
Q: What is the difference between a rooftop unit and a ducted unit?
A: A rooftop unit sits directly on the roof and blows air down through vents inside. A ducted unit uses your RV’s internal ductwork to spread the cool air evenly throughout the living space.
Q: How often should I clean my RV AC filter?
A: You should clean the filter at least once a month during heavy use. A dirty filter severely reduces cooling power and makes the unit work harder.
Q: Will an RV AC unit work without shore power?
A: Standard AC units need a lot of power, usually 120V AC. They will only run on a generator or an inverter system powerful enough to handle the startup surge.
Q: What is “soft start” technology?
A: Soft start technology gradually ramps up the power used by the compressor when it turns on. This prevents the sudden high power draw that often trips smaller generators.
Q: Are rooftop units hard to install myself?
A: Installation involves sealing the unit to the roof and connecting electrical wiring. Many people do this themselves, but it requires careful sealing work to prevent roof leaks.
Q: Why does my RV AC unit keep freezing up?
A: Freezing usually happens because of low airflow (dirty filter, blocked vents) or low refrigerant levels. Check the filter first.
Q: How long should an RV AC unit last?
A: With regular maintenance, most quality RV AC units last between 8 to 15 years.
Q: Should I get a single or dual AC system?
A: If your RV is over 30 feet long, or if you plan to camp in very hot climates, a dual system provides much better, more consistent cooling for the entire space.
