We had a leak in the drain part of our "in the attic" air handlers. As per normal, this happened around 5pm on a Friday night. Nick came out, found the problem, and had it fixed in short order. He explained everything that was wrong and what he did to fix it. He was knowledgeable, competent, and a pleasure to have around. I will definitely ask for him to do all of our future maintenance servicing. He is definitely a top-shelf guy!
