Trouble located, motor removed, part ordered, insurance company contacted and repair complete in under one hour of MY time (two visits under half hour each). While at my home, I found Aaron friendly and conversant, and careful of his impact in my super clean space. He keeps his tools and work vehicle clean and organized. Four Seasons was the second contractor called for my repair, after I learned that my appliance insurance policy uses his service. The first company I called suggested the wrong repair and even suggested the appliance was old enough parts may not be available, and that I might need a whole new furnace! All for a seized up motor. Thank goodness for Aaron's honest expertise!!

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"! It helps other Yelpers. If you liked my review, follow me on Yelp or send me a friending request. Stay safe and healthy and keep Yelping!

When you buy a former hoarders property you know there will be problems that need fixing. With our…read more'new' home, we inherited an old furnace that had a slow but steady gas leak, that periodically refused to heat and basically guzzled a full 250 gallon propane tank every month just coughing out cold air. It was costing us $500 a month, for nothing. Having just bought the home, we were cash poor. We are not made of money. I contacted five local companies for help. Paying $160 an hour plus a call out fee for a dying furnace seemed a waste of money to us, but it's what others wanted to charge us before they would even come out and look at it. We were concerned that they would spend two minutes looking at the furnace, pronounce it dying, which we already knew, take the money and leave. That's not service. Colin, of Clean Air Heating & Cooling was different, he offered to come out and take a look and take it from there. We were so relieved. He duly made an appointment, and turned up when he said he would. Here was a technician who actually arrived on the day, and time that they said they would. I was already impressed. Punctuality is important. Time is money, if you take a day off work for an appointment, you can't wait in all day for nothing. He checked it thoroughly and gave us various options. To repair it, (and he outlined the probable costs) or to replace it. He made sense. With such an old furnace, with total long term neglect we would be throwing even more money away. Did they even do parts for it? He went through everything thoroughly. What did we want? What was our budget? What was important to us? Did we have allergies? When were we thinking of doing the project? Did we need help with financing? Did we need a payment plan? We were most surprised at the reasonable cost that he quoted that we signed on the day. We agreed when the project would start and I couldn't wait! One thing that I need to add here, it's all very well having a new furnace installed, but if your duct system is leaking, and/or dirty the benefits of the heating provided will be lost, through the vents. I hadn't even thought of that. Luckily Colin had. More sense. We arranged for that to be done by them too. (See my separate review for that). The old furnace was removed in what seemed like minutes. They were safety conscious, thorough and efficient. I was impressed. They obviously know what they are doing. Next came the installation. Because of the former owners DIY installation of the old furnace, David and Isiah had to work extra hard and fix all those problems first before fitting the shiny new furnace. We hovered in the background, fascinated by all the work being done. They worked well as a team. Installing the furnace was not easy, but they managed it. We were excited to see it progress. Much testing and double checking later they fired it up. Wow. The 95% efficient furnace quietly purred into life, and before we knew it we were all sweltering and hot. My husband and I smiled at each other. Just wow, we were so glad that we chose this company! As David checked all the vents for the temperature, I mentally vowed to turn the heating thermostat down. We are delighted with the work done. The furnace is quiet, completely efficient. The house is warm. No more propane wasted. We can already imagine the savings to our heating bill! We are now fully ready for winter 2021. The work was completed on time. They were polite, friendly, informative to the work being done. They cleaned up before they left. All in all, we cannot recommend them highly enough. Everyone at this company goes above and beyond to ensure the job is done. They are reliable and complete professionals. Our next project is a new Tankless Water heater. We WILL be using them for this project as well. (Review to come when the job is done). See pictures attached.

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.

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.

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.
