From the quote to the completion of our renovations, Delta was a dream to work with. Jason, who provided our quote, was courteous and knowledgeable. Not only did he look over the duct work and gas lines, he answered questions about our fireplace, windows, and plumbing system, and he gave us the names and numbers of reputable companies who could help us in areas that Delta couldn't (ie. windows). He then offered to expand a portion of our venting system for optimal airflow and to replace certain gas valves that were no longer up to code. The quotes we received from other companies also admitted these valves weren't up to code, but then they shrugged and said they were probably fine anyway, whereas Delta agreed to replace them at no additional cost. Steve and Sean performed our renovations, assisted by a trainee whose name I didn't catch (sorry). They completed every detail Jason and I agreed upon, replacing valves, venting, and installing our new furnace and air conditioner all in one day. I've had trouble with contractors in the past showing up drunk or doing shoddy work, but these guys were fantastic. They arrived on time and worked hard, taking only a short break for lunch. They cleaned everything up before they left, and Steve stayed behind to explain the work they did and how to use and take care of our new HVAC system. I would wholeheartedly recommend these guys to anyone looking to replace their furnace or AC unit. Never in my life has a renovation gone so smoothly.
