A/C in my Hurricane

inlyzbldcj · 06-26-2021, 10:28 PM

Question for you experienced Rvers for me the rookie....I have my A/C set on auto 74 degrees for the A/C to come on....it is 101 outside today and I just returned to my RV from playing ball in a softball tourney....the A/C was on but it is only 87 in here...why isn't it cooler? The A/C's are blowing COOL air, but not COLD air....is something wrong with my A/C?

Nope - most seen to work that way. The biggest heat gain is through the windshield so Magna shade or Reflextix will help. Roof A/Cs cool the inside air going across the coils by 20 degrees. Your coach has single pane windows, R-5 insulation in the walls and R-18 in the ceiling. The heat load is more than the A/C can handle. Best advice is to staying the shade. Search this Forum for A/C and heat advice.

Research Delta-t and learn about AC. You can use that term to search the forum for a lengthy discussion.

What about running the cab AC with the engine running while on levelers....would that be ok?

Yes. as long as the engine doesn't overheat. In the summer we run the generator and both roof A/C in addition to the dash A/C to keep the coach cool when traveling.

Use a thermometer and check where the air goes into the filter on either side that is your air in the rv if it is 87 the air coming out should be 20 degrees or more less than the air going in 67 or less. Also when was the last time the ac filters were cleaned. If the fan was on low and the air went from cold to warm the AC evaporator coil could be frozen the fan must be put on high and the compressor off till it melts the ice

I have a 2021 34J. Anyone have issues with chassis A/C?
Is it a problem to run generator and roof A/C's if needed while traveling over road? Is there a conflict with generator/12 volt system or does generator override ?

Your Battery Interconnect module (BIM) will keep the 12 volt power sources isolated.

There are several things you can do to make your ac unit much more efficient

Here are a couple of YouTube, Coleman and Dometic.

First, no problems running the generator to use the house AC while traveling. We do it all the time.

The chassis AC is a different issue and you may want to start getting it check sooner rather than later. Part of the AC is warranted by Ford while the inside ducting and other components are installed and warranted by Thor.

So there are a number of different things that you have to consider. First, is that number a measurement you made or on the display. I ask that because the location of the front AC temp sensor results in incorrect values. My RV is 74 degrees, but the display says 78. Secondly, you should measure the temp coming out of the cold side of the AC. There are only so many degrees it can drop.
I recently installed RV AirSystems upgrade, and the increase in airflow is surprising. My AC cycles on and off all the time now, instead of running all day.
