Torrence responded to my message within 30minutes of my post and because he stayed within minutes of my home added my Air Conditioning service call to his already full list for the day. I would definitely recommend his services to anyone looking for quality and punctual work. Not to mention the price was extremely resonable.

I would like to begin by saying it was great to work with a company that truly knows it's business. I replaced the enter HVAC system in my home and contacted multiple contractors for the best resolution to the heating & AC issue that I was having. Pactick came to the house & was able to diagnose the problem & resolve it, along with pricing and a time line for installaion. I am a very satisfied customer. Patrick yoiu ROCK! Keep up the good work!
