Commercial AC Repair | Everett, WA

Commercial AC breakdowns we diagnose

Work starts with amp draws, refrigerant readings where the charge is verifiable, condenser airflow checks, and how the panel executes its published sequence of operation—so fixes target provable cooling faults, not guess-and-replace parts.

What we see on Seattle commercial AC systems

  • No cooling, warm supply air, or compressors that will not start or stay running
  • Contactor pitting, capacitor drift, or single-phase electrical faults on rooftop and split equipment
  • Restricted condenser coils, failed condenser fans, or high head-pressure trips
  • Thermostat, sensor, or BAS commands that do not match what the equipment is doing
  • Heat pump reversing valve or defrost faults during shoulder seasons

How findings get communicated on site

Expect narration that connects meter readings and commanded outputs so owners and facility leads can weigh repair spend against capital timing—whether that means closing the ticket now, budgeting a packaged-unit swap, or tweaking schedules without burying an underlying mechanical fault.

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.
