Iain from WIN Electrics installed our ducted vacuuming system and did a really terrific job. Professional, knew what he was doing, and got the job finished quickly. We've never had any issues or problems and it's been nearly 2 years since he installed the system for us. Because of the way the house was built, we initially had problems as we were told we couldn't have a ducted vacuuming system, but Iain was able to work though that and brainstorm some ideas & did an amazing job for us. Highly recommended!!
