Trane central air conditioner
by Ace B
Trane air conditioning units aren't bad. The one thing I don't care about Trane central air conditioner though is that they still use a hermetic compressor in some of their units. The scroll compressor is said to be 15% more efficient and operates with less noise and moving parts.
In my mind the top three brands are Trane AC, Lennox, and Rheem. Rheem I tend to lean a little more towards since they don't seem to be as "pricy" and from my experience in the field, they hold up just as well as a Trane, or a Lennox.
Also understand the importance of the install, - its the most critical day in the life of the air conditioner units. A central air conditioner unit
not installed correctly won't operate at its max efficiency and the compressor will experience a shorter life.
Since most installers aren't required to have any kind of formal training, a technician will understand the importance of pulling an adequate vacuum on the system, checking its superheat, subcool, and external static pressure.
