From micro-breweries and medical suites to multi-family builds, a properly designed and serviced HVAC system keeps occupants comfortable, protects equipment, and slashes operating costs. Below, Duramax Heating & Cooling Inc.breaks down everything facility managers and general contractors need to know about commercial HVAC in the Pacific Northwest.
Why Commercial HVAC Matters
Comfort & Productivity – Studies show temperature swings of just 2 °F can drop worker output by 3 %.
Equipment Protection – Server rooms, kitchens, and labs rely on precise humidity and ventilation.
Code Compliance – ASHRAE 62.1 ventilation standards and Oregon Mechanical Specialty Code demand proper airflow and efficiencies. [ASHRAE]
Energy Costs – HVAC can eat up 40–60 % of a building’s utility bill. [DOE]
