Any HVAC contractor will tell you, it is easier said than done to get a system up and running. Among the factors to consider: equipment, climate, installation and cost. I came across an interesting case study from Rheem related to this. Here we have the right equipment, an understanding of the climate, and a great installation to top it off. If we were watching the ponies right now I'd say that's a trifecta.

Contractor Tito Gabilondo, owner of A.G. Service & Repair, Tucson, Ariz. developed a comprehensive custom HVAC comfort system for a 3,300 square-foot custom home in southern Arizona.

Gabilondo ultimately installed two 4- and 5- ton, 16-SEER Rheem air conditioners and matched them with two 80-percent, two-stage gas furnaces that feature GE’s ECM motors. To improve the indoor air quality in this dusty climate, he installed a Honeywell media cabinet that captures airborne particles to add even greater indoor air quality. The house also sports a PROTECH-branded humidifier into the system. All system components are managed by a two-stage thermostat.
