How to diagnose your RV’s air conditioner health

2

Certified RV technician Chris Dougherty shows you a way to diagnose the health of your RV’s air conditioner (or air conditioners) using an infrared thermometer. It’s a simple process, but one most RVers have likely never thought to check. Chris recorded this video while he was the technical editor of RVtravel.com.

A infrared thermometer like the one Chris uses in the video (and the one RVtravel.com carries in its Mothership), is available at Amazon.com.

Very good tip. Thanks. Here’s another. A pin wheel will also provide an indication of flow rate. Seeing a obvious difference of flow coming from identical opposing vents caused me to investigate further. I found several little leaks in the distribution baffle underneath each of my ACs. I was air conditioning the interior of my roof. Using aluminum tape to patch the poor workmanship, I increased the air flow into the room noticeably. This is something you may want to do to the unit of your dreams before you buy as well.

I have used the infrared thermometer to check my tire axle temperatures as I travel. Never thought to use it to see how the A/C unit is working. Thanks for the tip.
