The LED assumption being they will be less maintenance? I don't think the information available supports that assumption safely. The one or 2 LED's that worked for James for barely a year are no longer available. James has a new LED that may work, but not even on the market yet. I have a client that emphatically wants LED, yet I have no product to offer that has any track record whatsoever. I guess I really don't understand the scope. If the systems don't run when the clients are not home for 10 months out of the year, then maybe it is ok to install and not come back for a year? I really don't have any experience with this, so I cannot know if it is a good idea or not.
