Recent Review: I like to cook. I have a small town home - it would fill up with smoke very fast without good ventilation. So, I purchased a commercial grade hood to go over my stove/oven. Hired a local handyman to install venting, which by my own admission was somewhat complex as the options for venting to the outside were limited. Handyman installed venting (according to hood instructions - or so we thought). We cooked. Place filled up with smoke - not good. Learn after reading range instructions ourselves that handyman did not install proper venting. So, we opened the walls back up and ripped his work out. Time for plan B. Thankfully, we had met David earlier that week, doing some major work on our HVAC system. We asked if he could help and, despite a second request for us to work over the holidays, he didn't bat an eye. Came out the next morning, assessed what needed to be done, and was back the next day to complete the work, which included some customized venting fabrication. These guys are great, that's all I can say. Knowledgeable, fair pricing and get the job done right - no shortcuts. I highly recommend.
