Let's the hvac contractor choose on the brand. I mean, he/she is installing the central air conditioner units. Each contractor has a brand that they prefer.
Coleman is another York Unitary Products Group brand name. If I were to favor one brand and the hvac contractor is inexperience. It'll only make the good brand worse.
The only thing I can tell you is to focus on hvac contractor. The contractor decides if you have high efficient unit or the worse efficient units. The brand doesn't really matter.
Good luck shopping

P.S
Would you share your previous central air conditioner experience with other homeowners? What brand was it and how was the central ac unit.
