Horrible, do not use this company for anything. Six weeks to improperly install a new HVAC system. Gas connection was wrong 3 different ways: 1. Actual fittings and configeration was wrong. 2. They connected into line going to my dryer, rather than running new line to the new gas furnace. 3. The gas line that they tapped into was not big enough to supply the furnace, let alone furnace plus a dryer. Add that to every gas connection made by their HVAC guys leaked and had to redone by their plumber. Their plumber refused to run direct line to the furnace, as it needed to be. Also had issues with the new humidifier being installed wrong. Water ran directly from humidifier onto and into the furnace. soaking all of the electronics, and leaving standing water inside the unit. At this point I demanded that they take it all out and give me my money back. They sent a senior ops manager to bully and intimidate me, claimed there was nothing wrong with installation. Back to 3 different problems with gas line, and the system being flooded by the improper instalation of the humidifier. He kept telling me nothing was wrong and it was all perfectly safe. Sorry does anyone really believe that water and electricity mix well? As for minor problems, in general it looked awful. Many problems with this install and how it was left. Six weeks with 6 in pipe open through the roof, they didn't take it out and repair roof as promised. They ran the new exhaust pipes in front of my electrical outlets, to where I would not be able to use them. I was left to repair a lot of damage caused by them. Everything that they did had to be taken out and done correctly. At this point, I wouldn't trust them to change a lightbulb.
