The average person looking at a wing cross-section would think it pushed down, not lifts up. Common sense would fail them there. And not wanting to be disagreeable, but I think common experience (emperical results), not common sense, guides most good gardening. We often don't know specifically why something works, at least in any rigorous sense, but we know what has worked reliably for others and ourselves. Reasonable, common sense solutions can sometimes lead us astray. Common sense might easily have all our pear pruning in the dormant season (as with most other deciduous fruits): practical experience shows that some summer pruning is often more effective. Common sense had us removing lawn clippings from the lawn ("leads to thatch buildup"): actualy experience (experiment) shows that leaving them is best apparently and has nothing to do with thatch. It is often hard to figure out when to defer to authority (whether university or neighbor) and when to go with the gut, with common sense. Fortunately in gardening, experimenting and failing occasionally has little risk.

Ok. I ordered the Laura Bush. Planted the seeds and now I have the sprouts!!!! Got 4 packages....if the bunnies don't eat them and Sam (my dog) leaves them be, I have some petunias!!! Also, talk about luck, my neighbor gave me three starts of her self-seeders.....how blessed am I!

advisor - maybe we just are reading this differently: "contractor is saying we can run 10 inch off the hood and then "choke it back" to the 8 inch for the majority of the run. " You see , only an idiot would got to the trouble to install an 8" to 10" transition at the hood and then immediately add another one going in the opposite direction to go back down to 8". So what is likely happening is there is the takeoff at the hood at whatever size to 10" for a run of between 2 and 24 feet at which point there is to be another reducer of 10" down to 8" for the rest of the run - or majority as o.p. says. This leaves a big belly in the middle of the assembly. If you think this is good design then you are certainly entitled to your opinion, but fancy website aside I say you're wrong. You are correct about the transitions 8" to 10" is quite common , you can get one of the shelf at your local home depot, and VAH will even sell you one. They'll even sell you one of their wacky 8" plus 6" dual takeoff to 10" round if you get one of their larger hoods. BUT, I'm not letting any contractor go from 8" to 10" back down to 8" again in our projects. You can do what you want, and I'd suggest mrd gets someone that knows what they are doing locally to advise him/her because 1. neither you or I are on site to see what's actually going on, 2. have not been engaged to design the system, 3. seems that the onsite HVAC guy is not quite on the top of his game based on the quoted gameplan. RE: the 600 cfm, might be enough, but what if it's actually not in this case. Are you going to pay for the swap, refund the consult fee, ect.??? I know 900 + will work because it there is a lot of xtra headroom built in. It might cost more, or maybe not as VAH is proud of their hoods, but that cushion is nice. You also do not mention how loud that VAH is going to be especially on full tilt ! May not be important to mrd as (s)he didn't mention it - but what if it is???? Doesn't seem prudent to make a rec to a stranger that is too conservative - but hey it's a free country.

Hi eam44! I understand how frustrating it can be when you have been given a specific promise from a vendor, so you have an expectation and then that expectation isn't met, over and over... I did a bit of research for you; don't worry about that, because academic research is what I do for a living, so I actually enjoy it. I can say with confidence that this company is not fraudulent, nor are they scam artists trying to get your money for nothing. What they are bad at is customer relations. What they teach you in business school, and what I completely disagree with, is to never tell the customer something will take a long time, or that they really don't know how long it will take. Their reasoning is that if they tell you something will take three months, or indefinitely, you won't buy it. But if they tell you it will take two weeks, you will buy it. You'll hate them for it taking so long, but research shows that very, very few people will cancel the order. I had a friend in college who did telemarketing for extra cash. They were doing surveys for the GOP, among other things; it was an election year. They were told to tell people that the survey would only take 5-6 minutes, when in reality it would take almost 45 minutes. During the survey, when a customer would ask how much longer it would take, they were always supposed to say five minutes. The problem was that in polling, you can't use the data from an incomplete survey. But it has been found that once people agree to do the survey they very rarely hang up before completing it, even when it becomes obvious that they were misled about the length of the survey. This is not considered fraud under the law. This company, as I said before, is not fraudulent. You'll get your vent liner eventually, or they'll tell you they can't source it and give you a refund. I think you have a few options here: 1) Call your bank and have them dispute the charge. Tell them the original delivery date and the number of times you have received email from them. They will have a certain number of days to respond. My guess is, if they can at all control it, you'll get your product before the 30 days or whatever the time limit is for them to respond. If you don't get it, they have no control and are relying on another company to get it to their warehouse. At that point, you could cancel the order and get a full refund. 2) Call the customer service department of #AppliancesConnection.com and try to find out what's going on and get a realistic delivery date. Remember that you catch more flies with honey than with vinegar. I almost always get my way when I call customer service people because I am super polite, never, ever raise my voice, and always start out by saying I know none of this mess is the fault of the person I'm speaking to. Always find out the name of the person you are speaking to, and write it down! Use their name throughout the call, because this helps establish a personal relationship. Use a low, soft spoken voice throughout. Actually, literally, smile because that helps you maintain a pleasant voice. Work in something personal, like the weather (Wow, it's been snowing all day here; what kind of weather are you having?) Other safe topics are, I love your name, my favourite aunt is named...or my dog is chewing on my shoe again! Do you have any pets? Etc, etc. I also make various threats, but super politely in a friendly, soft spoken way. Example of an actual call I made in 2002 regarding a bathroom plumbing issue (starting after opening pleasantries and brief explanation of the problem) : "I really, really don't want to call the Better Business Bureau, Irene, because you're a small, local company and I try really hard to support local businesses, and I'm really happy you're open on Saturday; thanks so much! And I know that even a couple of negative reports with the BBB can really hurt a small local business that relies on word of mouth. But I just don't know what to do. I'm actually just about to start crying. You and Mike [the plumber] both seem like very nice people, and I know this isn't your fault, Irene, but Mike was supposed to be out here six weeks ago to finish fixing my shower. I'm 42 years old, and I've had to share a bathroom with my parents for six weeks. Between you and me, Irene, it is really gross sharing a bathroom with people in their 80's. Would you want to share a bathroom with people in their 80's? So, like I said, I'm quite reluctant to report you to the BBB or the plumbers association, but I don't see an alternative if my shower doesn't get fixed immediately, especially since we've already paid you." I HAD A WORKING SHOWER 45 MINUTES LATER. :-) That was in 2002. Today we also have social media. I was trying to get a refund from Amazon for a $25 bath mat that I never received. The conversation (via online text chat) was going nowhere until I nicely informed the customer service rep that I was going to place our whole conversation on Facebook. I got a $25 credit I could use to reorder the mat or anything I wanted to. 3). Call and email them AND send them a certified letter where they have a receipt they have to sign upon delivery, and CANCEL the order. Call your bank, tell them you cancelled the order and get a hold or return on your charge. This is different from disputing the charge. When you dispute the charge and you get the delivery you have to pay for it. When you cancel the charge, you don't get the hood liner and you get your money back. I assume they have some sort of return policy, and since you haven't even gotten it yet, it must still be in effect. After you cancel and they try to deliver it to you, REFUSE the delivery. Do not accept it! 4) Just wait it out, do nothing, and wait for it to arrive. 5) For all options 1-4, SAVE ALL CORRESPONDENCE!!! This is very important. Save all email on your computer; also print them out and save hard copies. Either record all phone calls or write down everything everyone said as soon as you hang up. This means saving everything they wrote and said, AND everything you wrote and said. And save everything you post on social media and everything they post, if they respond to you on social media. I'm really sorry this has been so frustrating for you! I'm just starting a whole house renovation, and I've already freaked out a few times, lol!! Try not to let it get the best of you. YOU can choose your attitude and your mood. Don't allow them to choose it for you. I hope this helps! :-)
