I called Kevin based off the Yelp reviews. He was pretty knowledgeable and said based off what I described it sounds like a capacitor. He sent out his son in law, Chris. Family business which I always like to hear of and support. Chris was also very knowledgeable and quickly identified the bubbled capacitor and had it replaced. What I liked was that they were quick to send someone out and get me cold air when it was 112 degrees outside. I would use them again and recommend them to others.
