We chose Ed Kuhn and his team because they were the only ones who said they could run ductwork to all the rooms in our upstairs (3 rooms and a bathroom) and for the same price as the other guys who would only run it to 2 rooms. The house is an old 1938 craftsman style so it's really only 1.5 stories which translates to lots of sloped ceilings and very little overhead space. In fact, they were the ones to discover just how little room there was in the ceiling. The whole ductwork layout had to be reconfigured on the fly but in the end it came together very nicely, didn't cause any significant delays and the best part, no change to the cost of the project! On day 2 we had 7 people in the house working on the ac and electrical which seemed a little daunting (it's our first big home renovation project) but they were very efficient and we were glad that it got done so quickly. The group was polite, accommodating (per my request, they placed the unit and cement pad outside on several inches of gravel since it's located close to a downspout) and made sure to clean up all their trash when they left. Since we weren't home when they finished, Ed was came by the house the following night and talk with us about the installation and answer any questions. He's a very nice man and we were glad that he was overseeing the project himself; he was the one calling us if anything came up (i.e. moving the ductwork) and keeping us informed of the project's progress which we appreciated. We have an older ac on the 1st floor and if does need to be replaced while we own this home we will definitely call Ed.
