Phoenix heat in summer w/Class A coach

We are about to start looking for a home in the Phoenix area and need to be in the area to do so. We are in a 2011 HR Endeavor with 3 AC units.

We know the temps are brutal in Phoenix in the coming months and that RV's don't do near as well in such heat as a house does... but just how bad will it be for us in the RV in 100+ degrees?

I know we will probably need to run the AC units full time while there during summer... is it possible to keep a coach like ours comfortable in 100+ degree weather?

Are we crazy to consider this option???

==========U P D A T E==============
FAST FORWARDING TO TODAY... AUGUST 6TH

...FOR THOSE WHO HAVEN'T READ THE LATEST POSTS IN THIS THREAD... WE ARE PERFECTLY COMFORTABLE HERE IN THE PHOENIX AREA, IN OUR COACH, RUNNING JUST 2 OF OUR 3 AC UNITS!!!

WE HAVE BEEN HERE IN PHOENIX WITH OUR COACH FOR OVER A MONTH NOW (JULY INTO AUGUST) AND WE ARE LOVING IT.

? NO SILVER FOIL NEEDED OVER THE WINDOWS.

? NO NEED TO BLACK OUT ALL THE WINDOWS.

? AWNING PROVIDES GOOD SHADE TO MAJOR WINDOWS.

? NO AUXILLARY AC UNIT NEEDED.

? NO SHADED OVERHEAD STRUCTURE NEEDED.

? WE ONLY NEED TO USE TWO OF OUR 3 AVAILABLE ROOFTOP AC UNITS.

WHEN THE TEMPS HIT 110+, WE MAY USE ALL THREE NOW AND THEN, BUT WE HAVE FOUND THAT WE HAVE NO WORRIES ABOUT THE TEMPS WITH THIS WONDERFUL COACH - IT'S A KEEPER!

THANKS, ALL.

  • My suggestion would be to stay in one of the high country areas, Prescott to Pinetop, and drive down on daytrips looking for your house. You will enjoy and may change your purchase location a little. Phoenix is too hot for us also so we looked South. The elevation also increases as you head South and the Summers are much more comfortable. By the time you get to Nogales on the border the elevation is 4,000 feet and rarely over 98 degrees which is 20 degrees cooler than Phoenix. Tucson's elevation is half of the increase and so is the temp at about 10 degrees cooler than Phoenix. Buying a house and staying all year is different than Snowbirding and requires a year-around point of view. Good luck in your hunt!

  • Go to home depot or lowes, search for a roll 4ftx24ft insulation barrier. foil on both sides with bubble wrap in the middle. Don't care how you install it or hang it. But it would work better on the outside. This will keep the heat out, make rig dark and will allow the AC to work efficiency. We live outside of Apache Junction, base of the Superstition mountains and know too well about the heat. But this stuff really works. Summer = Outside, Winter = inside.
  • With 3 units, should not be a problem. We only have 2. 95% of the time fine keeping 72 inside. The problems have been during extremely hot, power is low. So check wherever you stay for power. As others have said shady spot if possible, awnings out, blinds and curtains pulled. And if you have to pull in a slide or two. Less cubic ft to cool.
  • It is possible, but I'd heavily suggest some portable A/C units to help out the overhead units.
  • Add one of the portable 120 volt AC units that have one or two hoses that vent to the outside and it will help. We have one and it helps a lot in the really hot temps and since it is a heat pump also, it helps in the Winter. They are not that expensive and they come on wheels so that you can roll them out of the way when you do not need them.
  • They are showing 112 plus today for Phoenix. Was there the first part of the week and it was hot. Both AC were running all the time. Your show 3 AC. should be OK. As stated shade, water and close off all windows with something. Have fun, we did. And don't turn them off if you get cool.
  • It can be done! When were in Lake Havasu, AZ. in early October it's around 103* we have a Winnebago with 2 AC's and were at 83* inside the coach. It's very hard to properly cool in Arizona due to there's very little humidity and AC units work off of humidity. Lake Havasu is about 1,500 lower in elevation than Phoenix and on most 100* day's the humidity is around 8. What we found to work best for us is if possible park under a shade tree, get a chrome reflector type windshield sunshade, and start cooling your coach down in the early in the AM as possible. Also, if you don't have them get a shade protector for your tires (wheel cover for your tires), that hot sun and the UV Rays will cause ozone cracks in older tires. I tried cooling my coach down with water my first time in AZ. and what a mistake that was! The water is so hard it left large water spots all over the coach. It made the windows hard to see out of. And if you wash your coach or car do it in the shade and wipe the water off as quickly as possibly, never wash in AZ. out in the sun. And for drinking water we never drink anything in Arizona but, RO Water (reverse osmosis). The PH in AZ. is about 6.5 (very hard water) where in Washington State most places it's 8.5. We also go to laundry mats that feature soft water to wash our clothes in! All of this info is just IMHO, thru experiences the wife and I have been thru in AZ. (3 years in AZ.). Good Luck and Happy trails! I'll be down there in AZ. for 6-7 months in October.
  • Yes, it can be done, but you will only get the temperature down 20 - 25 degrees from what it is at the present time.
    Try to park in the shade if possible.
    Don't be going in & out all day.
    Close all shades & blinds.
    If you have an awning - use it!
    If it get's too windy - close it!
    I just looked at the weather for Lake Havasu and it's 112 right now and will go up each day.
    Friday: 125
    Sat: 127
    and then drops off a little for 4 or 5 days!
    Drink lots of fluids (not beer) & RELAX!!
    Good Luck & Drive Safe!
