When my son became licensed in commercial refrigeration and air conditioning over 15 years ago, his instructors taught him two basics:
1. Trane units require Trane parts for repair. Those parts cost more than the generic parts that most other brands use, and are not superior in performance. It simply assures revenue for Trane when repairs are required.
2. Heat pumps are more complex than standard air conditioners that use heat strips for heat in cold weather. Accordingly, heat pumps require maintenance and repair more often, generating revenue for service technicians. In Florida where winter weather is brief and not severe, heat pumps are not needed.
