I have mixed feelings bout Northwest Energy Systems (NES). I used them 3 times, once to install a…read morewater heater (great experience; original review), a second time to repair a gas leak (things went terribly wrong), a third time to investigate this oily burnt foul smell in the kitchen (dissatisfied). PROS + Most of the people at NES are nice. Chris in Sales is professional and easy to work with. Dan, the own, went out of his way to make things right when my gas leak repair went REALLY bad. CONS - When I had a gas leak in the garage, this one technician misdiagnosed and replaced a gas pipe that was not leaking. A few hours after the technician left, I called them to ask to send the technician back as I was still smelling gas in the garage. The receptionist REFUSED to send him back because she did not believe I was still smelling gas. As it turned out, the technician had replaced a line that was not leaking. After spending several hours, the technician finally located where it's really leaking. Unfortunately, this is not the end of my ordeal. They put a temporary hookup so that I can at least use the water heater before they can fix the leak on a later day. Then, the temporary hookup leaked! It was after hours, but I called NES and left a message for the on-call person. I ended up having to call the Cascade Natural Gas emergency line as I did not receive a call back, and Cascade Natural Gas shut off my main gas line. Because of the misdiagnosis and the failure to respond to my after-hour request, Dan, the owner, gave me his personal cell number in case I have difficulty reaching them. - The same technician was sent to my house a couple days ago when I requested to investigate the foul smell I noticed in the kitchen. Ok, the previous time, he was reluctant to investigate the issue any further as he thought he had fixed the leak. This time as well, he was reluctant to do anything. First thing he said was "I don't know what to tell you." So, I asked him to at least check for a gas leak. 10 minutes later he left, and I received a bill for $92.40 ($85 trip charge plus tax). As I requested a service call, I did pay (the entire bill), but I expressed to the office my concerns about this technician's unwillingness to help me TWICE. I am not even calling this technician incompetent, but it's a waste of money at least if he's not willing to help his customers. The office promised me to send someone else in the future. It is my Yelp review policy not to name names to avoid "public shaming." However, if you're considering to hire NES and want to know which technician I'm talking about, please PM me. I can share the information in private. ************************************************************ If you found my review helpful, don't forget to hit "useful" and/or "cool"!

Not a customer, but a neighbor of a customer. There was no reason why their van had to be parked on…read morethe sidewalk, but it was. This sidewalk connects two sections of a heavily-used recreational trail, but because it was parked on the sidewalk, people had to walk into the street to get around it. Lots of elders in this neighborhood use that sidewalk for their exercise. There isn't a sidewalk on the other side of the street that people can use instead. I contacted the company via FB to let them know, but got no response. I'd waited an hour before posting here hoping that my FB message would prompt them to move it. Didn't happen. It was parked there for at least an hour before I went to FB. I know who I WON'T be calling for HVAC services. Rude, y'all.

Terrible experience. I had a power outage that caused my Napoleon fireplace to stop igniting and I…read morecalled Clean Air to come out and see what the issue was. The tech Michael came out and immediately seemed perplexed by the issue but after about an hour and a half of messing around determined that it was the main control board and that he would get me a quote for a replacement part and to come back out. He then billed me over $350 for the diagnosis. I then waited a couple of weeks pestering the main office to get my quote for the repair. Guess how much? $1500. $1000 for the part and another $500 for labor and tax. I have some connections and managed to source the part myself for less than $300. I've heard of cost plus markups on parts but triple the cost.....really? I got Clean Air and Michael to agree to come out and replace the part using the part I sourced and only charge for labor. Guess what? After spending another hour or so replacing the part there was a new error code and the fireplace still didn't work. Michael promised to reach out to Napoleon to help him diagnose the problem and get back to me when he had an answer. That was 4 weeks ago and I never heard from Clean Air or Michael again. Like a fart in the wind. Gone. Not even a courtesy call letting me know that they had no idea how to fix my fireplace and sorry about me wasting $1000 on a part and 2 useless service calls. I guess I just had it coming. In the end I called Innovations. Their tech came out found a high limit switch tripped and reset it. No parts required. Less than 30 minutes to fix it. Thanks Innovations. You rock!

Yep I kept tract.Then I wanted continuous hot water so they put in a combination boiler /hot water heater that lasts another 20 years (3 years ago) and it has worked great. Altho it cost more than I had paid in the past I don't have to keep switching out water heaters every 6 years. I think they do quality work at a reasonable price. Never upsell. Always on time. If they break a part they replace it free. They use good parts. They have an annual service which gives you 10% off for the year if you have the annual service. The best heating repair. They put in furnace and AC for my neighbor and found her a great discount. I had discounts on my boiler yet I got quality equipment. This last year they replaced a motor piece in my 20 year old gas insert fireplace. Great Work, Good prices, helpful staff. Ethical.

Andgar was the original contractor for our office HVAC, but once individual office walls were…read moreerected and furniture/cubicles moved in, the airflow and climate control went completely out of whack. People in their offices are sweltering and those in cubicles are either freezing -- wearing coats, hats, and blankets indoors -- or sweating and stripping off layers. These temperature extremes are only 5 to 10 feet apart. Also, the system for regulating temperature and fans is clunky: thermostats near a vent actually operate vents across the room and they're not very intuitive. It takes an engineer to program it, and I work with engineers. We're still freezing/sweltering. Makes no sense. Anyway, just wanted to put my 2 cents in while my fingers still have feeling.
