My least favorite part of testing homes is telling customers that their 1 year old HVAC system is too big for their house/ductwork. I run in to this at least 2x per week. Something needs to be done about HVAC contractors selling customers whatever they can, and require that they do proper sizing and design work. 3 of the largest HVAC contractors in our area do not perform Manual J, or Manual S calculations AT ALL! Looking forward to many more episodes of this, hope that this show gets to the average consumer, rather than just the building science community.
GREAT WORK! As a HVAC contractor, I hear it all the time....."BIGGER IS BETTER". People need to hear and see the truth and understand that there is no magic standard number for sizing their HVAC equipment and no two houses are the same.
Glad to see it happening! Of course I want to see more details on the testing but this may be good to show a standard homeowner that there are testing options for these sorts of things.
Great episode! I would love to see a results segment, a before-and-after, to wrap it all up.
We would have loved it too, but we didn’t have the money
@@HomePerformance could you have updates after the problems were fixed on your youtube channel? Like a skype chat with the homeowner or something
Great idea, we’ll check on them!
Great idea, we’ll check on them!
Awesome work Corbett and Grace! I always hate telling clients that the equipment that they just installed or the work they just had done was not done well, but it happens all the time.
Great job on the show. As always I want more. More details. More pictures. More verification. Etc. But you have done a great job of keeping it appropriate for the average home owner who may watch and learn from the show. Congrats!
Thanks buddy!
Nice work. Particularly liked Grace in this episode. She managed to more than balance out Corbett this time. A quick followup would be a perfect wrapup.
Fantastic explainer, guide, We appreciate you
Thanks for following my friend
@@HomePerformance my pleasure
Great job guys! Looking forward to the rest of the season.
Awesome footage, nice quality.
Prograde service and sexy tools.
Helpful content as always, I'd love to see more. thanks for being ninjas and always inspiring!!!
Thanks for following, Bob!
Great work! 👍🏻
Thank you for posting on you tube. My local PBS (WVIZ) doesn't carry the show so Joe Medosch from Hayward Score led me here. Good show. I'm also a fan of John Bower books. Only bad moment was when I saw a Method and Mrs Meyers bottle near your sink. Anne Steinmann PhD has found hazardous pollutants. "Fragrance" and even "natural fragrance" is b.s. for the chemicals.
Thanks for following! Yes, don’t get us started on indoor chemistry, it’s a very deep hole with no end in sight.
Very interesting watching this as I'm a domestic energy assessor in the UK.
I find home owners here saying the same things. Condensation on widows is usually down to high humility in kitchens/bathrooms, we don't often have HVACs in homes only extract fans, which people never turn on while cooking.
Surface condensation such as that you found in the attic would likely be due to either insufficient heating to increase surface temperatures or inadequate insulation resulting in excess heat loss and thus reduce surface temperatures. I was surprised that you put this down to poor air tightness. Did the room even have heating in it?
Surly removal of the over sized HVAC system is unnecessary, it would just run at a less efficient rate to a "correctly" sized system?
IHOW inadequate summertime dehumidification occurs with systems sized so large that they short cycle - turn on and off before adequate dehumidification is completed.
So far so good. ...:) Good Luck with series. ...*
I hope you do a follow up. Great first show. Will keep watching. You make a great team, and can really see the time spent together. I chuckled a few times at how similar your speech patterns are. Makes me wonder if you guys stick to a script of just bullet point and go from there. Wish you and the family all the best in 2019. Ty from chicago.
Thanks for watching!
Pretty confident this is the same problem I'm having with my house.
Also I like how the cold-air return ducts in my home were not connected to anything going to the actual furnace.
😭
You guys are great!
Best production of any Home Performance show I have seen, keep it up and best wishes. Will this be airing on cable/streaming/pbs?
Thanks- we premiered it on PBS stations this week, Gary! It’s running on almost 40% of all stations nationwide now.
Nice double teaming the client!
you keep equating missing insulation with air leaking around light fixtures, they are not the same thing
Not equating, but they often go hand in hand
Awesome
I'd love to see some outcomes, after all "proof is possible". Diagnosing is less than half the battle. IMO.
We would too- hopefully next season we’ll be making the show with some more money. Pass the word along if you know any potential sponsors.
Are you going to be at the ahr show
Yeah buddy
Home Performance do you have your own booth? Or how can I find you
Get in touch during the show, I’ll be walking the exhibit hall fundraising season 2, happy to chat
so what happened? wheres the follow up? kinda got left hanging.
also would have liked a better explanation of why the big hvac was causing the issues. (hvac is rare here)
on the positive side it looks nice, nice filming, you looked really good and you highlighted some common issues. nice job!
We made this first season with almost no money, so enjoy what came of it! If the DOE or a network had taken the lead, we would have given you before and after.
@@HomePerformance at least its a start in the right direction. i'm so sick of "make it all pretty so we call sell it for heaps" shows.
An air conditioner will dehumidify while cooling the air. - Very basic description. Think back to when Corbin was testing wet bulb and dry bulb.
The longer it runs, the more humidity it's able to remove.
So if the hvac system is oversized, it runs a short period of time. Not allowing it to pull enough water out of the air inside your home. When sized correctly, it will run the right amount of time to efficiently dehumidify your home.
But that's just a small portion of the system. You need the correct size duct. To small you can't move enough air. To big and there is not enough velocity.
In this episode, Corbin specifically mentioned small ducts. He was referring to the return ducts.
A system is design to move so many CFMs per ton. Let's use 400 cfms per ton. A 5 ton system is required to move 2000 cfms in this example. So it needs to pull in 2000 and push out 2000.
Well if it's only pulling in 1200, it's only pushing out 1200. When this happens, you can't push enough air through ALL the ducts. Typically the furthest ducts suffer and you start to create hot/cold spots.
Really difficult to fully explain this on a social media comment. But this is the very basics of what Corbin was talking about in this episode. At least it's what I picked up on and combined with my little bit of knowledge and experience.
Great description
@@HomePerformance Thank you!
I love working in the HVAC trade, a few years ago I made air flow my "thing" to improve in my skill set. Still have a long ways to go. But i have come so far.
Класс))!!
Thanks, I think!
You mind as well be describing the Flintstones house that’s the level of information your describing. All of the information your talking about is the same information 70 years ago. I’ll tell you the same email I sent This Old House. If you want to talk about how or what to do go to Germany. Conservation in home building is now the norm because it is and was the law. You aren’t given a choice when it comes to insulation. When your ready to sell your house in Germany the prospective buyer doesn’t go to past sales or current market. They (the buyer) go to city hall and find out what the yearly inspection of the Chimney sweep have been reported on that house, that’s what controls house price. For a number of years in Germany you are not allowed to build a house that does not produce enough energy for itself and then some to sell back. The fact is that what they have is so effective it’s spilling over to commercial new building. The biggest compliment is other European countries are following the Germans. What we are doing in this country is continuing to make the same mistakes over and over some of you may get this it’s like watching Groundhog Day over and over and expecting a different outcome.
Wow, a real live time traveler come back to tell us we're dumb! Thank you!
@@HomePerformance your response is typical of the rest of do it yourselfers. Not sure how you fit time traveler in but one day, when you have time look up in the sky and you see those things flying overhead they are called Airplanes and that’s what us time travelers ride on. You can ride on one use one of those things you see people holding up to their ears and talking into. We are also using a thing called internet if you go to a library they will show you how to use it. While your there look up en.wikipedia.org/wiki/Passive_house you may learn something you didn’t know can you imagine well maybe you can’t.
