I got my CT last October, so I never got to use the A/C, until last week. It's been in the 80's and humid, so I set my A/C auto temp to 75, thinking that would be a comfortable setting (my home A/C is set to 78, which is fine). Well, it was not. The air coming out of the vents was barely cool; it felt like a fan. So, I started cranking the temp down. It wasn't until I hit 68 that I noticed a difference, and settled on 66 as the optimum comfort level. This doesn't seem right to me. If I set my home A/C to 66, I'd freeze to death! Is my A/C not working as it should?
