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

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.

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."

*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!

I pay a lot of money to be on a maintenance plan so they come on on a regular basis to check the heating system, and supposedly they prioritize your service needs if you do need urgent service. First of all, clearly their maintenance isn't that great because my radiant heat is not working. Secondly, "priority service" doesn't exist -- they won't be able to service my un-heated home until mid-November. Will be looking for another service provider in the future. Very disappointed in their service.

Chris came to inspect our 30 year old boiler and thermostats. We had been having a heat fluctuating issue. He was very informative and showed me the batteries that are in the thermostat that I had no idea were there. Of course they were dead after 30 years but they kept the connection between the thermostat and the boiler and were calling for heat even after the desired temperature was reached. New batteries and we are back in business. We will have Chris come in a month and do a full boiler inspection and update. We were impressed with his professionalism and knowledge. Pricing was reasonable

Even though we were not able to do business to repair my boiler, Kathy was able to help me with tips and referrals. She later called back to see if I still needed assistance and if I was able to resolve my problem. She gave that personal touch that every customer should get from every business. Thanks, Kathy!

Sometimes, you get what you pay for. Although Northwest Mechanical costs a little more than some others, their pricing is fair. What's more important is that they know what they're doing, do quality work, very responsive, and we can get a diagnostic and repair appointment fairly quickly. Also, unlike many other plumbers or tradesmen, they show up on-time. Their work is professional and they stand behind their work. I would recommend Northwest Mechanical to my friends and family.

Just had a heat pump installed, replacing our gas furnace in a very old home. They were great from start to finish. Informative estimate, including what options were available and which they would recommend, and the work happened right on the schedule they set up. The installer, Brendan, was very knowledgeable and did an excellent job adapting our old forced air system to the new heat pump. Kept the place clean, and kept us informed. They also represent Mitsubishi heat pumps, which are very quiet inside and outside. We're happy, and recommend these folks for this type of work.

I had purchased this new home and the previous owners gave excellent reviews for Northwest Mechanical, so of course I reached out to them for my regular maintenance. Kyle was super helpful, as he walked me through the boiler system and he even had much of the history associated with this installation having done regularly scheduled maintenance in the past. I was reassuring to have that level of history and knowledge of the unit.
Kyle even installed a new thermostat up in the kitchen which I hadn't noticed had stopped working.
Overall, this has been an excellent investment in our home, which is

Great service, found a small leak in my baseboard hydronic heater and needed a yearly boiler service. They had someone out the next day. He was extremely efficient, had the system drained and the pipe fixed in about 30 minutes. Then the service on the boiler was very thorough, cleaned it out, checked all the safety mechanisms, and made a few tune ups to make sure it was running well. At the end of it all, he made a coupe suggestions of things that made need replacing or updating, but he was not trying to sell me on anything, he was very respectful, he just laid it out and said these couple thing

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

This is the rating for a business that ripped us off from the initial service call and wanted us to have us pay around $20,000 to install a new furnace which we don't need.

We wanted to get a checkup on our furnace to ensure that it wasn't leaking gas (we live in an old house with the original furnace still intact.) Since PSE was apparently swamped and the company they referred us to was also swamped, we're by extension referred to NW Mechanical. We paid them around $100 for a service call which ended up being worthless: everything related to the furnace was apparently broken and

I highly recommend. I've used NW Mechanical for almost 10 years now on a quite complicated, and poorly installed, radiant heating system in my house. They also do maintenance and support work on a rental we own. Recently they helped me re-route radiator piping, install new radiators, and re-balance the ferrous and non-ferrous halves of my boiler system. They're technical, fast, competent, and they show up when they say they're going to. Their bills aren't a surprise (meaning, they charge you what they say they're going to). If you have a technically complicated job, they

Had NWMechanical install a ductless AC and replace the hot water tank in my house.
Was extremely impressed with the workmanship, professionalism, and work ethics.

Estimates were on spot, they kept schedule, were respectful of my dwellings, kept the place as clean as possible, and even though they had to come in/ out of my house continuously, took their shoes off every time they came in (yes, I found that impressive!! :))

Really couldn't ask for more, and have already scheduled additional projects for the house with them.

Mark took the time to give me awesome advice and detailed information on radiant floor heating. He actually educated me out of a sale for himself, because it's actually not the right product for our home, but he was candid and honest. He could have "sold" me because I knew nothing about this, but he didn't. Can't ask for much more than that!

Thanks for the info Mark!

I have a three story townhouse with a complicated Hydronic heating system. They took the time to explain the system to me and I've been in great hands. The one time I called another company out, I had to bring in Northwest Mechanical to fix that company's mistake. These guys are so great I signed up for their annual service plan.

Pros: On time, experts in this field, professional staff, they accept credit cards, they have an annual service program that can save you $$

Cons: they are pricey but worth it!

When does the air conditioner need work? One of the hottest days of the year - of course! We decided to pay for an emergency call and the technician, Aaron came out in 5 hours. He diagnosed it quickly, discussed fixes, installed a trap, tested it and accepted the check. You might find cheaper service somewhere but you may get what you pay for. This is the second time we've used them and it won't be the last.

From scheduling through repair and follow through I am so pleased with the service. When you have no heat you feel panicked and worried that you could be easily taken advantage of. We have a radiant heat system that we knew zero about. Aaron took the time to explain what needed to be done to get it working and how to operate and maintain it going forward. I am so very thankful I chose them, we will definitely be back for future service and repair needs.

Very professional.

They mostly specialize in mechanical aspects of residential and commercial and might handle your plumbing needs if you are already an established client or they happen to be working on your property for another issue.

They are swamped with clients because they are dependable for the job to be done correctly. So be patient and anticipate a 1-2 week wait for your appointment.

Pricing is moderate. I have a boiler system and full house radiant heated floors so i have to be extra careful who can work on my property. If the boiler water is cross contaminated with the drinking

The only company that didn't run away from my Solar/Boiler heating system issues. I swear my heating system is the most complicated system in the world, but NW Mechanical was up for the challenge. They were exactly on time and stayed as long as it took to complete the job correctly. I attempted to contact a few other highly rated local mechanics on Yelp, but after i emailed them a picture of my system, all i got back was NUTHIN. Quote was fair, final bill was fair, and i was very pleased with the thorough nature of the tech. I will call NW Mechanical again when the time comes for my yearly

Northwest Mechanical really stepped up and did right by me! Mr. Ryan Burgett contacted me to obtain more information about my complaint, after doing some investigation on his own. After I provided more information, he provided me with a refund on the service fee AND put a $50 coupon in the system for a discount on future work. Wow! I'm very impressed with how Northwest Mechanical "walks the talk" of striving for 100% customer satisfaction. Now I'll probably use that coupon with them toward a big, fat ductless AC unit just because they were way cool!
