Choosing the Right RV Air Conditioner: A Buyer’s Guide
An RV air conditioner (AC) keeps your mobile home cool and comfortable. Finding the right one takes a little homework. This guide helps you pick the best AC unit for your travels.
Key Features to Look For
When shopping for an RV AC, several features make a big difference in performance and comfort.
Cooling Capacity (BTUs)
- What it is: BTUs (British Thermal Units) measure how much heat the AC can remove. More BTUs mean more cooling power.
- How to choose: Small campers need less power (maybe 10,000 BTUs). Large RVs often need dual units or units over 15,000 BTUs, especially in hot climates. Always check the size of your RV interior space.
Energy Efficiency (EER/SEER Ratings)
- What it is: Energy efficiency ratings show how much power the unit uses to cool. Higher numbers are better.
- Why it matters: If you camp without shore power (using a generator or batteries), an efficient unit saves fuel and battery life.
Noise Level
- What it is: How loud the indoor blower and outdoor compressor run. This is measured in decibels (dB).
- Tip: Quieter units (often called “low-profile” or “whisper-quiet”) greatly improve sleep quality inside your RV.
Smart Features and Controls
- Some modern RV ACs have digital thermostats or Wi-Fi connectivity. This lets you control the temperature from your phone.
Important Materials and Durability
RV ACs face tough weather—sun, rain, and road vibrations. Material quality matters for a long lifespan.
Housing and Casing
- The outer shell, or shroud, needs strong, UV-resistant plastic. This material resists cracking from intense sunlight.
- Metal components inside should resist rust. Good quality copper coils last longer than cheaper aluminum ones.
Fan Motors
- Look for brushless DC motors if possible. These motors run cooler and last longer than older AC motor types.
Factors That Improve or Reduce Quality
Certain design choices directly affect how well your AC performs and how long it lasts.
Improving Quality
- Two-Stage or Variable Speed Compressors: These units adjust their power instead of just turning fully on or fully off. This keeps the temperature steady and uses less energy.
- Good Insulation: Quality insulation around the unit prevents the cold air from escaping too fast.
Reducing Quality (Things to Avoid)
- Cheap, thin plastic shrouds break easily during high winds or hail.
- Units with very low BTU ratings struggle in high heat, causing the compressor to run constantly, leading to early failure.
User Experience and Use Cases
How you use your RV affects your AC choice.
Weekend Campers
These users often have access to campground electricity (shore power). They can focus more on powerful cooling capacity for quick temperature drops.
Full-Time RVers and Boondockers
These users need efficiency. They should prioritize low-draw units or look into high-efficiency models that work well with solar power setups. Noise level is also very important for daily living.
Installation Type
- Roof-Mounted (Most Common): Easy to install, cools the whole space well.
- Through-the-Wall: Less common, but sometimes used in truck campers or teardrops where roof space is limited.
10 Frequently Asked Questions About RV Air Conditioners
Q: What is the standard size for an RV AC unit?
A: Most standard RVs use 13,500 BTU units. Larger or high-end RVs often use 15,000 BTU units, or they install two smaller units for better zone cooling.
Q: Can I use a residential AC unit in my RV?
A: You can, but it is difficult. Residential units are not designed to handle the constant vibration of road travel or the limited power supply in an RV park. RV-specific units are built tougher.
Q: What is “soft start” technology?
A: Soft start technology slowly ramps up the power needed to start the compressor. This prevents the sudden power surge that often trips campground breakers.
Q: How much power does an RV AC typically draw?
A: A standard 13,500 BTU unit draws about 12 to 15 amps when running on 120V shore power. Always check the specific model’s label.
Q: Do I need two AC units?
A: If your RV is longer than 30 feet or if you plan to spend summers in very hot deserts, two units provide much better, more even cooling.
Q: What is the difference between a rooftop unit and a low-profile unit?
A: A rooftop unit sits high off the roof. A low-profile unit is shorter, which reduces wind resistance and makes driving easier. Low-profile units often cost more.
Q: How often should I clean my RV AC filter?
A: You should inspect and clean the air filter monthly during heavy use. A dirty filter seriously reduces cooling power and strains the system.
Q: Can an RV AC run off an inverter/battery system?
A: Yes, but it requires a very large, high-capacity battery bank and a powerful inverter because AC units use a lot of power to start up.
Q: What brand names are usually considered high quality?
A: Dometic and Coleman-Mach are the two most common and trusted brands in the RV industry. They offer good parts availability.
Q: Does altitude affect RV AC performance?
A: Yes. At very high altitudes (above 5,000 feet), the air is thinner, and the AC unit cools less effectively. You might need a slightly higher BTU rating to compensate.
