New AC installation followed by an unseasonable cold wave !

My new AC was turned on and cooled my fifth wheel down nicely, Within two days the weather turned much cooler. I had to turn the AC off. The coolness is forecast to last indefinitely!

I rearranged my furniture and even vacuumed. 

Ordered and installed a portable air conditioner. That is all it took to change the weather from the usual very hot to a delightful cool. Could anyone use an AC?
