I dealt with Alan, Peter, Alex and two installers, Alex (electrician), and a gentleman who started up our unit. It took a few visits from the sales and install team to get the layout correct, but it worked out well. The contracting was pretty straightforward and clear. Alex the installation manager knows his stuff and gets the job done. The installers were neat, clean and professional. When they were done, it was neat and clean. They provided an electrician (also Alex) who was an honest guy, and worked hard. I thought I got value for what I paid him. The startup tech was also knowledgeable and pleasant. Overall a good contractor experience, especially why dealing with holes drilled through to the exterior of your home. It looks good, inside and out.
