Arizona and AC

[Mrblueeyes2020]

I live in Arizona , where Nevada , California and Arizona come together. The summer heat has started as it was 115 hear today.

My question is , my rooftop Ac unit seems to be struggling to keep up to wear it starts blowing warm air. At night and in the morning it runs great and will freeze you out , there is no shade trees here as it's the Desert , would putting a reflective cover over my AC unit help to keep the air flowing cold ?

I just drove through the area yesterday, thermometer said 112 outside. With both A/C's running in a 40' coach, it was still hot.

Bottom line, very unlikely that yours will keep you very cool in daytime temps like that even if the entire roof was shaded.

When it blows warm air your comprssor has shut off or frozen up. I had one acting similar to that and it was a bad thermister.

I would be very surprised if one AC could cool an RV in those temps but you didn't say what size your RV is.

Good luck

To answer the other part of your question, any thing you can do to keep the AC unit cool will help some.

We had the unit serviced at the end of November and was told all was fine with the unit.

If the outlet temperature is 20F cooler than the inlet temperature it's working correctly and you have inadequate cooling.
