These guys are, in a word....awesome. I've got a few properties around the valley that are rentals/etc, and I had them out to do 3 service calls. They were great about scheduling (big plus), showed up on time, did a very thorough job, and didn't cost too much!
An added bonus, they took the time to explain to me the ideal maintenance schedule for the AC units to keep them running in top shape for years - big plus in my book!
Bottom line - they're great! Use them, yelp them, share it around.
