Not too hard to install--if you're comfortable working on metal and HVAC systems
While installing this generally involves finding the right spot in your ducting (especially if you have a humidifier), cutting a hole, and wiring it up, it's easier said than done.  You likely will need a drill, Dremel, and/or snips, and most folks don't mess with their ducting much (the video provided by the vendor is a bit misleading, as you generally cannot just drill through drywall to install!).  If you know someone who does, it'll likely be easy for them.  The brightness of the bulbs makes it hard to QC things, as you cannot easily tell they're on without being blinded by severely unhealthy light.  I actually had welders goggles handy, which helped a lot.  The unit does have indicators on the outside, but if you want to verify things while setting it all up, be careful.<br /><br />In the end, it all works.  It was easier to install than a whole home humidifier, but more difficult than many home improvement projects.
