Seattle's high humidity and moderate temperature swings create specific challenges for commercial make-up air systems. Unlike dry climates where untreated outdoor air might work for part of the year, Seattle requires year-round tempering to avoid dumping cold, damp air into your kitchen. When outdoor temps drop to 30 degrees and humidity sits at 80 percent, an MUA unit without proper heating capacity will freeze out your staff and overload your HVAC system. Seattle's adoption of the International Mechanical Code with local amendments also means any hood system over 400 CFM must have code-compliant make-up air. You cannot skip this step or use undersized equipment without risking inspection failures and operational shutdowns.
Peak HVAC Seattle has worked with the city's permit and inspection process for years. We know what inspectors look for, what documentation they require, and how to design systems that pass review without delays. Our familiarity with Seattle's older commercial building stock also matters. Many restaurants and facilities operate in century-old structures with limited space for new equipment. We engineer solutions that fit your building's constraints while meeting current code. That local knowledge prevents costly mistakes and keeps your project on schedule.
