NW Mechanical is our go to place forever. We've used them before and they are very professional, knowledgeable, reliable and reasonable in their pricing. Aaron was our boiler expert. He was amazing he installed and fixed our problem and even instructed me on how to adjust the flow on some of our old radiators. I would highly recommend!

We had the fine folks at Northwest Mechanical install a combi boiler at our home and couldn't be happier with the whole process and the setup we now have. We spoke with several vendors and the team at NW Mechanical was quick to understand our home's requirements, our current HVAC + water setup, and nuances around the installation space. Clear communication, technically competent, punctual, and competitively priced. Highly recommend.

*We have a (new to me) boiler whole house system and have been using NW Mechanical now for 2 years, they are without a doubt experts at taking care of our heating system. I signed up for the yearly maintenance program for peace of mind and we have them out once a year to proactively maintain and test things. Running tip top and their techs are SUPER knowledgeable. Great outfit!

Critical: Professionalism, Responsiveness Used nw mechanical for boiler repair in the past. Called up for an emergency and they refused to service our home because it's been "over a year and we only service customers we've serviced in the past year." Service: Heating system repair

We ha a heat exchanger installed on 7/10/17 it worked fro 2 years. Then only cold air came out of our heaters. Then on 6/11/18 and 6/22/21 we had the same maintenance technician come out. The issue was not resolved and cold air remained to come out of the air vents. 6 months after the maintenance the heat exchanger stopped working completely. Because the schedule was full they couldn't send anyone out for 8 days.
Therefore we were without heat for 8 days. They sent a maintenance technician out named Chris who resolved all of our issue that we were having. Not only that he went above and beyond and replaced the batteries in the thermostat. He was very personable and we really enjoyed his company. We recommend Northwest Mechanical but we will always be requesting Chris!

Cole came out today and fixed a pinhole leak in the supply line to my in-floor radiant heating. I just opened the garage for him, he swapped out the leaking joint while I worked upstairs, showed me what he did, and then he was on his way. The trip charge covered the repair. He couldn't have made the process any easier. The only downside was having to wait a couple weeks for their availability to open up.
