I got quotes from several other installers (including the big box stores). They all quoted me in the $2800 to $4500 range and I finally went with 1st Air. These guys turned out to be the better choice. Met with one of the sales agents, and they installed it the next day. Installation was quick (less than 2hrs) and the guys were professional. Customer service was great too when I inquired about the coil's model and serial number in order to register my units for the warranty. Best money I've ever spent. No regrets.
