Air Conditioning Problems

We are experiencing tripld digit/high 90s heat. Although the controls are set on 68 or so, the coach will no cool down below around 82. Any ideas on a solution?

  • We have 30' with just two slides, and in the temps now, both are running during the day. In a shady CG last weekend, Outside in the 90+ range, we did very well with only one AC most of the time. Most RV units have no provision for adding gas, some techs can do it, some say it can't be done. But you should get about 20 degrees drop from either unit. I leave topside vents open most of the time, so hottest air can escape, and small fans front and back to circulate air better through the coach.
  • Two ACs. We are in a 39' pusher with 3 slides. In complete shade for the next 8 days. Dirty condenser? Where is the condenser? Assume it is on the unit on the roof. If I take the covering off, will I be able to see anything obvious?
    As to low on coolant, have to wait until we get back home and get it into the shop.

  • Find a shady place. What you have is about it, but do check the in and out temps. Do you have one or two ACs??
  • Measure the return air temperature then measure the discharge temperature and if about 20 degrees F +- couple a degrees, if so, then move to a cooler climate. If less than say 15D you might have a dirty condenser or possibly low on charge
    Have good blinds on the windows, out in sun all day, etc ?
