Very professional, informative, and friendly. Our AC stopped working and so we called MTB on a Sunday afternoon and they showed up in just 2 hours on a Sunday! Jason showed up and even put on plastic booties before entering our house. Once inside he was very knowledgable and offered some great tips. He spent about half an hour and the AC was back to normal. With so many other companies out there, I'm glad we made the right choice! Thanks again for your prompt service, and insight into the problem as well as helpful tips for the future!
