I finally brought the guys from Fox round lake heating and air (http://kriminal-ohlyad.com.ua) HVAC over to troubleshoot my A/C setup after it unexpectedly gave up the ghost right in the middle of that insufferable run of 90-degree days this past week. I figured I ought to post a quick shout-out here since I was completely stressed out searching for a contractor who wouldn't rip me off. The team were a lifesaver.
