Purchased in May of 2023.  Installed late June due to scheduling delays, install contractor was good.  Not in use most of July due to being out of town.  Worked great for August, then failed in September for unknown reason.  At this time, we have been without the ability to use for 2 weeks.  Parts shipped out to house, but repair technician did not show on scheduled repair date.  Now waiting for week 3 without ability to use - will see once repair is done.
