It's DRY Heat, But It's Still HOT! How to Stay Cool With Your RV Air Conditioning
"Help! My air conditioner isn't working, and it's so hot in my RV!" I can't tell you how often we get that type of frantic, sweat-induced call in the summer from both long-time RVers and those new to owning one. There are a few things you need to keep in mind about RV air conditioning and that you need to do to ensure your home away from home is cool and comfy.
While you're at the campground pool all day, shopping, or visiting the sights around the area, the RV is heating up inside. You've left the air conditioner off. It's 100 degrees inside when you return to the RV at 5 o'clock at night! Immediately, you turn that air conditioner on. Why doesn't it feel cooler yet?! You need to realize that the air conditioner has to pull the heat out of the carpet, bedding and couches out of everything inside before you start to feel cool. This takes time, LOTS of time. Here are a few things to avoid being miserable when using your RV A/C….
- The first thing you need to ensure is that you plug into at least a 30-amp service. RV air conditioners require 30 constant amps to operate. If you plug into a regular 110-house outlet and run the A/C, you'll have cold air for a few minutes and then warm or no atmosphere. A couple of things happen when you run the A/C plugged into 110. First, you only get 15 amps to the A/C, half of the required. This will cause the compressor to overload and at some point, fail entirely. Most times, that then requires a new A/C unit to remedy the problem. Also, look at the adapter on the end of your RV cord that enables you to plug into 110. You'll find it is severely discolored and often literally melted from the intense heat from the overloaded cord. A potentially dangerous situation.
- Turn that air conditioner on in the morning; by morning, I mean by 9AM. If you wait until noon to turn on the A/C, you'll never have a fantastic RV!
- Set the fan on HIGH. Using the low setting causes the A/C to freeze because of the lack of airflow.
- Set the mode to COOL. Don't use the Auto setting. When an A/C runs in the Auto mode, the compressor cycles intermittently, making the unit work much more than you want. Let it run all day; it'll do a better job, and you'll return to a fantastic RV.
- Use your thermostat to adjust the temperature inside your RV. If it's too cold, push it up a bit. If it's too warm, move it down a few degrees.
