Rated 5 out of 5 by 4 reviewers.
Rated 5 out of 5 by 8-7-14 Install The unit itself was severely overpriced. Way too much money but you have to pay if you wanna be cool in Tucson. At first I was upset because my house took 10 hrs to cool off after the install (2300 sq ft) but the days after we set the thermostat and Bam! All is well and feeling nice and cool. Electric bill seems to be going down. August 29, 2014
Rated 5 out of 5 by excellent system for the the price Bought this unit a year and a half ago. The system replaced an old gas furnace and window A/C units. The change in the air quality in the house as been amazing. The use of the MERV 16 filter has also dramatically reduced my sons and mine's allergies. November 16, 2013
