AC Performance

Going to AZ and wondering when it's 115 outside, and the coach is not under shade, what can we expect the inside temperature to get to?

Thank you

Tom,
If your ACs are working you should be fine. Use the awnings to shade the coach sides. You'll need to use the roof airs when traveling. Try to do any mountain driving (climbing) in the AM when temps are cooler.

Do you have 2 or 3 ac units?

Fortunately, the 115 forecasted temps will only be with us for a couple of days before it drops down to a balmy 103 or so.  At least for us in Tucson...if your unfortunate enough to be going to Phoenix, not so good.

You should be able to keep the inside temp in the high 70's low 80's during the worst of the heat.

Of course, someone will ask the question...Why?

One thing that helps on the forum is if we can see what coach you have.  You can add the year, make and model to your signature line so it shows on each post.
Our 98 Patriot had two roof airs and would drop the temp in the coach about 25 degrees over time.  The roof airs were fairly old.  We had a Marquis that had basement air but that didn't do any better in 112 degree.
Our current coach has 3 roof airs and they work well but we haven't needed them yet in the NW WA. Area.
A good cleaning of the A/C condenser helps.  I am not sure of a heat pump u it but a regular A/C can be cleaned  easily with some simple green for aluminum and a very soft spray from a garden hose.

Tom,
With only 2 roof A/C units (hopefully 15,000 BTU units), there is a good chance that you can see inside temperatures as high as the low 90s F with the outside temperatures that you are talking about and no shade. That is the reason that most of us Beavers who winter in Arizona head north in the spring. It is very hard to cool one of these fiberglass ovens in the Arizona summer sun. However, like they say, it is a dry heat, but aren't most ovens.

    Yup, Welcome to Arizona "dry heat" Cindy and me are living in our motor home and in the afternoon when it is 106 outside, we loose ground around 2:00pm and it gets up to 85degrees inside until about 5:00 and then catches back up. We use a tower fan in the hallway to help push all that bedroom cold air forward.
   We normally "Get out of Tucson" in May and June but can't do it this year. Still counting our Blessings we have a roof over our head and not homeless.
   Regards, Fred

Thanks to everyone who replied. We just purchased this '05 Marquis in April, sold our home in TO CA and are heading to the Phoenix area to purchase in the 55+ community. We like Sun City Grand, the coach has two airs which are both 13.5. The front air does not seem to perform as well as the rear. We have been told that there are no service ports to add Freon. We are planning on replacing it with a 15. While searching for a home we will be living in the RV, possibly at Happy Trails in Surprise.

Tom,
I wish that I was there to welcome you to Arizona. My house (winter base) is located about 15 minutes from Happy Trails, and there are probably well over 20 Beaver owners who winter at Happy Trails with most of them owning one or more lots.

The Beaver group has a potluck once a month, and we have several cookouts at my house during the winter season. So keep in touch, we would like to see you when we get back. Most of us get back in the October to November time frame after it cools off.

     Hi Tom,
If you want to check your air conditioners for proper operation with clean filters here is what you do. Check the temperature of the air that is entering the return air filter. Check the temperature of the discharged cold air coming out of the nearest register to the air conditioner. The temperature differential with no humidity should be 22 to 25 degrees. Humid air is more dense and harder to cool.
   Keep in mind that the front of your coach is twice the size of the rear and has 4 times the glass making it extremely hard to cool. Home depot has rolls of chrome colored bubble insulation if you want to "cut to fit" to put in the windshield or the large windows up front.
   Hope this helps, Fred
