    I recently bought a home built in the 70s, which had a past end-of-life furnace and which sensibly…read moredidn't have cooling, though I wanted it as its become increasingly important over the years. I pitched a project via Yelp to install cooling and replace the furnace to all of the most highly rated companies in the area. All of them recommended a heat pump as opposed to traditional AC. Better Air NW's proposal was not only the least expensive by a fair margin, but also offered the highest quality machines and best warranties. Normally, I'd be pretty skeptical at that combination, but all of the positive reviews on Yelp convinced me to accept their offer. A few days later, as I write this I'm basking in the warmth of my new heater. The installation was smooth, painless, and well done. Despite some unexpected challenges in the home's design to figure out and overcome, they charged exactly their estimate; there were none of the kind of headaches or scams that one often expects dealing with contractors. All in all, great experience, these folks deserve their lofty reputation.

    Had a great experience with Better Air NW! Customer service was excellent in helping us schedule…read more Communication was clear and they even give a heads up text when they're on their way. Corey was our technician and did a very thorough job. We had both our AC and furnace worked on. We will continue to use Better Air NW and recommend this company to family and friends.

    I booked AirGanic's services for duct cleaning, furnace cleaning, AC cleaning, and dryer vent…read morecleaning. They came on 3/6 in the provided time window, and did a good job of cleaning from what I can tell. On their website, they mention they provide a before and after report of the duct cleaning, though the only report I've received so far is the indoor air quality one. It would be nice to see the before and after, but that's not my biggest concern with their service. Unfortunately after they completed the service and left, I noticed floor new vibrations on the floor that is right below the furnace (which weren't there before the service). At the time since this was still during the day, I figured it might be from some construction work outside and ignored it. The vibrations continued into the night at which point I was getting concerned. I call them on Monday 3/9 and the earliest they can send someone to check it out is Friday 3/16 -- not ideal, but appreciated nonetheless. It's the same tech who did notice the vibrations on the furnace with the blower compartment open and fan running. Unfortunately he doesn't have an idea on what could be causing the vibrations from a cleaning. I suspect the vibrations to be from the blower going out of balance (perhaps from something settling on the blower during the duct cleaning). He goes to call his boss and returns saying the boss isn't also sure of what could be causing the vibrations, that the blower could be cleaned but AirGanic doesn't do it and that the boss would reach out to me with details of a company that cleans furnace blower. It's been three full business days and I've yet to recieve a call from the boss. I removed, cleaned, and put back the furance blower myself in the mean time which did resolve the vibrations -- it looked like there was stuck on paper on the blower fins. No idea where that came from. I'm not particularly happy with how my situation was handled -- if I am told someone will reach out to me, I expect to be reached out in a reasonable time. If I'm hiring a professional for a service and something unexpected happens, I expect help from the professional -- that's why you hire a professional. I was left without help and had to guess and fix the problem myself. Everyone makes mistakes, that's not what I have a problem with, I'm only interested in how well the mistake is remedied. I imagine this was something that doesn't happen frequently. In all probability, you'll hire AirGanic for cleaning, everything will go great -- I certainly don't contest that the cleaning itself was poor or unsatisfactory -- but if something unexpected happens, you might not get the help you are expecting.

We called AirGanics this morning because of no heat coming from our furnace, which we had installed when we moved in our house June 2021. We tried most of the morning, both email and phone to contact them. We couldn't wait any longer and reached out to another company to fix our furnace. We did a call back but was told they do not service "non AirGanics" installed equipment. I explained we did have AirGanics install our our whole unit when we moved in, but was told they had no record of us installing, just a consultation. So I forwarded the invoice we had paid to have the unit installed. I received an email back simply stating, "Checking our records now for that invoice. I did find that. Thank you So now I don't even know if the warranty on our less than 5 year old furnace will be serviced in the future, or will we need to go to another company. Just passing along our experience.

    I had my old furnace taken out first by another company and then had Howie's power vac come in…read morewhile the old furnace was pulled. You'll get a better deal that way versus having them vacuum while your furnace is still installed (basically there's an additional charge if your furnace is still connected and they may have to physically cut an access hole into your furnace to hook up the vacuum). Much easier if your furnace is already pulled out. They quoted me around $500 to vacuum all the ducts in my approximately 2000 square foot home and the final price came out to $350 before tax. They use a big truck mounted vacuum that does a much better job than places that have a cheaper service but use wimpy little vacuums. Ultimately they showed up on time and did good work. They were very professional throughout the whole process and the technician called me when the job was complete to review what he did.

We ended up paying around $350 for the entire duct system to be cleaned and we feel like we made the right choice. The whole cleaning job was about 3-4 hours. They actually connected a large diameter hose from the truck to the furnace.... then they ran an agitating line down each vent duct, thoroughly cleaning the entire system. We were extremely happy with their service. We will definitely be calling them back in a couple of years. Thanks!

My dryer was old (23.5 years) so first I got a new dryer. However, when that didn't help I tried to clean the dryer vent myself. I discovered that my dryer vent exits on the roof of my house - so I realized I needed to hire someone. As I researched companies, I discovered there is a vast range of pricing and expertise available. The cheaper companies (~$150) won't go on the roof and often only clean the vent from one side. Although Seattle Dryer Vent is not the cheapest, they are knowledgable about what they do and they do a thorough job. The technician arrived on time, was pleasant, and seemed to immediately know what the problem would be when I explained the problem I was having with drying my clothes. It turns out the the builders (my home was built in 2002) hadn't removed a mesh screen from the vent on the roof which was preventing my vents from fulling expelling the dryer lint out the end of the vent. The technician removed the screen as part of the service. Thanks to Seattle Dryer Vent Cleaning company, my clothes now dry in a reasonable amount of time. They were professional, knowledgable, and friendly and I would recommend them to others.
