York Versus Carrier Air Conditioners - Every manufacturer has their own parts system and sometimes these parts are readily available aftermarket and sometimes the parts are proprietary and can only be purchased through the manufacturer of that equipment. Carrier is one of the HVAC manufacturers that has proprietary parts and sometimes you will pay a premium for those parts.
The manufacturer can hold the customer hostage especially when it comes to repairing the unit. Of course, York is one of the big HVAC manufacturers and they too have proprietary parts however the parts are usually more reasonable for purchase as far as cost is concerned so people would lean towards purchasing a York simply because the replacement parts are not sold at a premium where with SOME Carrier parts are sold at a premium and are not easily replaceable except through a Carrier dealer.
