Founded on Technical Integrity

A/C Dr. Naz was built to solve a specific problem in the Puget Sound region: the lack of precision in mechanical repairs. Most contractors guess; we calculate.

As an EPA Universal Certified technician, I founded this company on the principle that commercial refrigeration and HVAC systems are high-performance engines. They require more than just a quick fix—they require an understanding of airflow dynamics, refrigerant chemistry, and electrical precision.

Whether we are performing a Friday-night evaporator replacement on a Nor-Lake walk-in or commissioning a high-efficiency mini-split system, our mission is simple: Zero shortcuts. Maximum longevity.
