  • NW Mechanical recently installed a new Hot Water Heater and a new Heat Pump for us.
    NW Mechanical recently installed a new Hot Water Heater and a new Heat Pump for us. The technicians were very knowledgeable, arrived on time and worked very efficiently. They answered any questions, explained what they were doing and what the equipment should do and the results we should expect. They were correct, we have been very happy with the performance of both. We highly recommend them for both new installations as well as service to maintain equipment.

  • I wish I could give Mark, a salesperson at NW Mechanical, ten stars. A hundred stars. ALL the stars!
    I wish I could give Mark, a salesperson at NW Mechanical, ten stars. A hundred stars. ALL the stars! How does amazingly generous customer service like this exist in 2018? Apparently, it is alive and well at NW Mechanical. Why am I so grateful and thrilled? For no apparent reason, my radiant baseboard heating system suddenly conked out in my house during typical mid-December, 42ish degree, pouring cold rain Seattle weather. In describing my current heating system and the problem to Mark, who was determining which boiler system would be the most efficient and effective for my needs, he learned enough about my current system to guide me through restoring heat to my house. What did it take? Flipping one switch. Oh, my gosh! If Mark had not been so knowledgeable, kind, and patient with my rambling descriptions, I would continue to be shivering in a cold house waiting for a service crew to arrive, diagnose the problem, flip the switch and hand me the bill. In the long term, what was even more valuable from today's call was the information Mark provided on what NW Mechanical can install in current day boilers that work far more efficiently than my current funky (my term, not his) boiler set up. Thank you, Mark. Thank you, NW Mechanical. Thank you for your excellence in knowing your trade and for putting this customer's needs front and center. If you want warmth and outstanding customer service, call NW Mechanical. They will take care of you.

  • Had them work on our house twice.  Decommissioning some kitec and installing a water heater.

    Had them work on our house twice.  Decommissioning some kitec and installing a water heater.  

    They were on time and still apologized over the phone about being a couple of minutes late, were very respectful, friendly and clean.   They weren't the cheapest quote I got, but I'm so glad I chose them.   

    Will do business again.

  • Very happy with NW Mechanical.
    We have a geothermal residential furnace. NW Mechanical has always been able to provide prompt quality service for this somewhat unusual setup, with courteous technicians. Very happy with NW Mechanical.

  • They worked very quickly and efficiently and left no trace behind.
    They had to cut a lot of holes in the walls of my house -- and afterward, you couldn't even tell it happened.

  • They did a really good job.
    They reinstalled a furnace for me and reconnected my hot water heating system. They were consistent with the price they gave me even though the put in more time on the job than anticipated. The gentleman that came out was very professional and took extra efforts to ensure the quality of the installation. They did a really good job.
