"Chad and his team were very friendly yet efficient and professional--they even came an hour early due to being ahead of schedule for the day. I am currently working from home and did not feel disrupted at all while they were cleaning my HVAC system!"

I am a jack of trades independent contractor/ handyman with 10+ years experience. I am not a licensed plumber, licensed electrician, or licensed roofer. With that said it's easier to just tell you the things that I don't do. I do not do drain work, I do not replace electrical lines or panel boxes, I do not replace plumbing lines which includes water and gas, and I do not replace roofs. Aside from that I can do everything else, and have the tools to do so.
