Winters in this part of Colorado run cold enough - the whole service area sits in a severe cold climate band - that an opener without a battery backup can leave you stuck outside during a power outage at exactly the wrong moment. In Castle Pines specifically, where more owners are asking for backup-equipped units already, that's less of a hard sell and more of a default expectation. Where it goes sideways is when the safety sensors ice over or shift out of alignment after a hard freeze, which reads to the owner as "the opener is broken" when it's really a sensor problem thirty seconds from a fix.
The other place it goes sideways: a homeowner wants a specific smart-opener model with a feature we haven't got in stock on the truck. Some of those units run on a supplier lead time that isn't something we control. We'll tell you straight if what you want isn't sitting on the shelf that week, rather than installing something close to it and calling it the same thing.
