Very well. We have relied on NWM for any work needed within their genre. And they stand behind their work.

Hot water heater replacement. Service on in floor radiant heating system.

The original founder of the company was very good to us when he installed the system and they have done good ever since.

They serviced my Honeywell air filtration system and the gas furnace.

After we accepted their recommendation for corrections, the two person crew arrived on time at the scheduled date. The crew worked very hard until about 7:30 PM to get all the work done so heat and hot water could be restored to our home. Early on in the day, the crew showed me one internal part of the boiler that had been seriously damaged by the installer and they fixed it at no additional charg...

Maintenance and corrective work for a boiler providing heat to an in-floor radiant heat system and domestic hot water. NW Mechanical identified problems in the service and installation of our modern, high tech condensing boiler - that had been installed and serviced by a competitor. The boiler had started periodically producing trouble codes and would shut down. The competitor that installed and serviced the boiler could not find a solution after making three trips over 6 weeks. On their first visit, NW Mechanical took all of five minutes to find the problem. A part of the boiler had not been cleaned by the competitor during the annual service 6 weeks earlier and was clogged. NW Mechanical recommended we correct errors in the plumbing and wiring of the boiler system to improve efficiency and safety.

We chose to pay for an emergency call and Aaron came out 5 hours later. He diagnosed the problem - plugged drain - discussed solutions and we had him install a trap. No, it wasn't cheap but in a lot of cases you get what you pay for. This is the second time we've used them and won't be the last.

We had purchased several new gas appliances and during a service call learned that our existing gas piping was under capacity for the appliances we have, so we called two piping vendors and NW mechanical gave the best advice and made the best proposal all around.  The other vendor was slightly cheaper, but they were surprised that we insisted that the work must be inspected by the city, which shoc...
