Manual J Load Calculations in Arizona
Permit-ready Manual J, D & S reports for Arizona HVAC contractors — built for the extreme cooling loads of the low desert and the cold winters of the high country. We serve Phoenix, Tucson, Scottsdale, Mesa, Chandler, Flagstaff, and contractors across the state.
Manual J for Arizona's Climate
Arizona spans Climate Zones 2–4 — from the cooling-dominated low desert to the cold, high-elevation north. In Phoenix and Tucson, summer cooling drives the design; in Flagstaff, winter heating does.
Sedona, Arizona
Phoenix & Tucson
The Valley and southern Arizona see extreme summer heat. Cooling loads dominate, and a detailed calculation keeps equipment from being oversized for the short shoulder seasons.
Flagstaff & the Rim
Flagstaff and northern Arizona sit at high elevation with cold, snowy winters. Heating leads here — a statewide cooling assumption would size equipment wrong.
Desert Sun
Arizona's intense solar radiation adds substantial heat gain through windows and roofs. We account for orientation, glazing, and shading rather than a flat estimate.
