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 charge. The crew found one small part that was not working and replaced it at a reasonable charge over their original estimate. They fixed several other small issues they encountered at no additional charge. The boiler system now works great, with no more problems. I highly recommend NW Mechanical for modern condensing boilers and radiant heat - which many local heating companies have limited experience with.
Description of Work: 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.

Description of Work: We have used them for 6/7years. They did the annual inspection. We have radiant heat system and not very many people locally know how to handle that type of of system and they have been very good. We pay a monthly $27 all year round and that gives us priority if we have a problem.

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 shocked us. We had a planning meeting to go over our goals and make a detailed plan. The representative, Larry made good suggestions about what we needed and adapted well to the few requirements we had (leaving certain locations clear and running piping in certain areas to maximize storage space). The workers showed up on time each day and worked hard all day. The work was very dirty, but they kept it all within the workspace and covered all walkways they used to keep them clean. The new gas and radiator piping looks beautiful and well designed. A couple tiny leaks were quickly solved with a call and free visit. The total cost ended up under budget and less than the other vendor had proposed. The new heating system is using dramatically less gas than the old and the temperature is more consistent and comfortable all day. It's also almost completely silent as opposed the the jet engine in the basement sound our old header made.
Description of Work: Upgraded internal gas pipe capacity (meter also upgraded), established new gas distribution stack, converted old open radiator system to closed/pumped system, removed old boiler, replaced with new boiler.

I have used this company for years. Recently I needed a quote for a new boiler. They were $3k over any other estimates and charged $350 for just a quote. This is not unusual with this company. They are always trying to gouge their customers. It's a shame because they have hard working knowledgeable stuff.

I contacted the company in the late afternoon, at about 16:55 to 17:00. A woman answered the telephone. I told her the city/town that I resided and that I wanted a ductless heat pump system to be installed in my home. She said that the cost to come to my home and create a bid would be at least $250 because I lived outside of her company's service area. I thought to myself that the bid should be free because all of her company's competitors that I had contacted gave free bids. She said that she would have another employee telephone me the next afternoon. After 10 days, I still have not received a telephone call from the company. I have concluded that the company did not want my business.
Description of Work: I contacted the company one time via the telephone to schedule a meeting at my home for a ductless heat pump installation.

When everything was said and done, I paid Northwest more than $200 with no work done. They charged both a service visit fee and a diagnostic fee. A technician diagnosed the boiler problem and said it would be another $600 to perform the repair. I asked if Northwest would waive the service fee for a return visit to perform the repair (I did not want to proceed with a repair at this price without obtaining other bids), and they agreed to this. I did find a reputable company that charged $400 for the repair.

I have been a customer for many years and had this company perform an annual (required) check of my backflow prevention device and boiler-fired heating and DHW system. About two days after the last service call, I ran out of hot water. The boiler was running, the DHW demand icon was lit, the DHW pump was running, but the valve between the pump and the DHW tank was in the closed position. I turned it open, and the system funtioned normally. The technician had accidentally left this valve closed at the end of his tests. Because of this oversight, my DHW pump had been running continuously against a closed valve for almost 48 hours, which undoubtedly damaged it. I notified Northwest Mechanical in writing of this error, and asked them to contact me to discuss a remedy. They never responded to my letter, or subsequent phone calls. They were always happy to take in the neighborhood of $200/hr for their services, but unwilling to even acknowledge my complaint. I would strongly recommend avoiding this company.

The field technicians did an outstanding job. One note of caution is to verify the experience level of the technician with your particular home mechanical system. The efficiency and effectiveness of the office staff is absolutely terrible. They have not followed through on commitments to schedule final permit inspections or delivery warranty documentation without an abnormal amount of followup.

Aaron from NW Mechanical came out to our house and gave us a detailed bid, which gave us a few different options to choose from. We ended up having them re-pipe all of the radiators in our house, along with installing a new boiler and hot water tank. They also put in the pipe from the gas meter to boiler. They were great to work with, came out and did the work as scheduled and got it done in a timely manner. There was one joint that was dripping slightly after they were done, but they came right out and fixed it up. All in all it was a very good experience.

I'm completely disgusted with them. I have a new house so it's real work but they will not even give me the time of day. If they are too busy to take on new projects they should just admit it and not waste peoples time.

THIS IS ONE OF THE MOST PROFESSIONAL AND KNOWLEDGEABLE PLUMBING OUTFITS I HAVE EVER WORKED WITH -- AND I HAVE WORKED WITH QUITE A FEW. THEY ARE COURTEOUS, RESPECTFUL AND CAREFUL WITH ONE'S HOME -- THEY PUT A PROTECTIVE BARRIER ON THEIR SHOES WHEN THEY COME INTO THE HOUSE. I HAD SEVERAL PEOPLE COME OUT AND TALK ABOUT RADIENT HEAT AND NW MECHANICAL WAS BY FAR THE MOST KNOWLEDGEABLE AND WILLING TO WORK WITH MY FINANCIAL CONDITIONS. THEY ARE ALSO EXPERT PLUMBERS AND WILLING TO SHOW ME WAYS TO SAVE AND BE CURRENT IN TERMS OF CODE AND WATER-SAVING DEVICES. THEY WERE WILLING TO DETERMINE HOW THEY COULD INCORPORATE MY PLANS FOR A RAINWATER HARVESTING SYSTEM INTO THE NEW PLUMBING I AM PLANNING TO HAVE INSTALLED.
Description of Work: I RECEIVED TWO VISITS FROM NW MECHANICAL -- ONE FROM THE PRESIDENT, BUZZ BURGETT AND ANOTHER FROM A PLUMBING TECH. BUZZ CAME TO OFFER FREE CONSULTATION ON A PROJECT OF MINE TO INSTALL RADIANT HEAT THROUGHOUT THE HOUSE. THE TECH CAME TO BID ON A SEPARATE PLUMBING JOB AND TO REPAIR A SIGNIFICANT LEAK I HAD IN MY KITCHEN SINK.
