Two, bay all means Two.. Many of our elected leaders and others try to convince us that Global Warming is a myth but every year for the last several years has set a new record as the Hottest Year, and hottest "Summer, Winter, Spring or Fall" on record.. Also I'm not sure if it's ended but for the last several days where I am we have set a new record for the most consecutive days over 90.
In short The globe is getting warmer, and the warmer it gets the more you are going to need that 2nd A/C...
OH, just for reference, on my Rig 37'7" I have ONE 15,000 btu at this time and if I can go 5 Degrees below outside. It is night time.. So I'm sleeping OK, but during the day it's gotten into the 90's often this last week.
New 2nd A/C on order, Installer on order, May arrive this afternoon (I hope) I'm tired of eating out.
