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.

Great company and great owner! The owner of this business responded to our request very fast at night time when our commercial walk-in refrigerator broke down. He and his team helped fix our walk-in refrigerator the next day. Now it has been many months since we got the walk-in refrigerator fixed by this company, the refrigerator still works great!

My walk-in cooler broke down on us Friday night. I called Dr. Naz, and he showed up a couple of hours later and figured out the problem. He said he'd contact me with estimate first thing in the morning on Monday, and he actually did. He offered to replace our evaporator by Wednesday, and yep, he did it. He really knows his stuff and keeps his word. You can totally rely on him for your service needs. His price was fair, no hidden fees, and it even came with his own 1-year warranty. Highly recommend him; he's my go-to cooler guy now.

Nazar did an excellent job repairing the refrigerator at my restaurant in Seattle. He was very responsive and was able to schedule a same-day diagnostic, which was a huge help. The repair was handled quickly and professionally. I highly recommend A/C Dr. Naz to anyone who needs reliable commercial appliance repair.

We hired them for a commercial freezer installation and couldn’t be happier. Communication was clear, pricing was fair, and the installation was completed smoothly with great attention to detail. They tested everything thoroughly and explained the setup clearly. Highly recommended for any commercial refrigeration needs.
