Serving 6 Western States
Local climate expertise combined with national industry standards. We understand the unique challenges of western building codes and climate zones.
Where We Serve
Idaho
Idaho's cold winters and moderate summers create significant heating loads. Our design professionals understand zone 5 and 6 dynamics, managing heating demands while optimizing summer cooling in transitional spring and fall seasons.
Oregon
Oregon's mild, wet winters and dry summers require careful analysis. We account for marine influences on the coast and continental effects inland, ensuring proper load calculations across diverse regional climates.
Washington
Washington's maritime climate presents unique challenges with high humidity and moderate temperatures. We design systems that handle coastal and Cascade region conditions, from Seattle's mild winters to eastern Washington's harsher climates.
Arizona
Arizona's extreme summer heat demands precise cooling load calculations. Our expertise ensures equipment sized for intense desert conditions while managing minimal winter heating needs in Phoenix and across southern Arizona.
New Mexico
New Mexico's high-altitude and high-desert conditions create complex load scenarios. We account for thin air, intense solar radiation, and wide day-night temperature swings to ensure accurate calculations from Albuquerque to northern mountain regions.
Utah
Utah's diverse climate—from salt lake region humidity to high-altitude mountain valleys—requires regional expertise. We handle variations across northern, central, and southern zones with precision and local knowledge.
Why Local Expertise Matters
Tim Neumeyer grew up in the western US and built Manual J USA on deep knowledge of these regions' climate, building codes, and contractor relationships.
Regional Climate Knowledge
We understand microclimates, elevation effects, humidity patterns, and seasonal variations across 6 states. Generic calculations don't work—regional expertise does.
Building Code Expertise
Each state and jurisdiction has unique code requirements. We stay current with local codes so your reports pass inspection the first time.
Built on Relationships
We work with local contractors, builders, and inspectors. We understand your market and your customers' expectations.
