The problem is customers have no way to judge quality until something goes wrong. So price is the only thing they can compare.

Some owners don’t realize they’re losing money until tax season hits.

Made the switch about 4 years ago. The physical side caught me off guard first. Residential you’re moving maybe 150 lbs on a bad day. Commercial RTU you’re rigging 800 lb units onto a roof with a crane and coordinating with a crew. Completely different animal.

You can tell where each one stopped caring.
Everyone fixed their issue, nobody owned the whole system. Now it all technically runs, but nobody wants to touch it without first undoing someone else’s work.
