Why is it that I keep coming across rooftop units (mostly Lennox it seems) which are way over-complicated and have so many optional features which are never used?
How much more is the customer paying for a unit with the option for zoning, fire alarm integration, smoke detectors, etc. when they're not even being used? It's just a 2-stage rooftop for pete's sake!
Is it just to keep the plumbers from working on it?
