The New Carrier hvac line is really a great fit for our company. It has a great line of systems for 20 seer to 13 seer. The Infinity series really goes above and beyond bringing greenspeed intelligence into the system. We have installed tons of Trane XL16 and XL20i systems and they dont even compare to the comfort and quality of the Carrier Infinity systems.
The Frigidaire brand is new to the phoenix area but they have been around for years. There product looks really nice and is built strong. The have systems from 22 seer down to 13 seer. These system are really affordable and come with 10 year unit replacement warranties.
