If you have an HRV can you just swap the core to an ERV without buying a new system?

My home was always cold in the winter with an air exchanger I bought a dehumidifier and now my home is no longer cold
Comment from : @dmjmercer

what would cause mold to develop on an ERV core? Mine is moldy
Comment from : @shellderp

ERV can grow mold when it's not working

I'm in Eastern Canada, just across the border from Northern MainebrWhich one would you suggest?

Horrible audio quality

Do Spot ERV's for one room focus have drainage pans? Do all ERV's have to be drained everyday? I have stale air problem and a dehumidifyer for wet cool air
Comment from : @brianmahoney2079

I had an ERV and it plugged up with bugs Cheap intake filter(VENMAR) Couldn't clean out the ERV recovery core If the core is soaked or gets wet, the recovery core gets ruined Very costly to be replaced How do you clean out a core if plugged with bugs Vacuuming would not work Cleaned it with water and Guess what? Ruined the core Venmar wanted 1100 dollars for replacement and cost me 1200 for unit (No way I would buy another core)HRV core can be washed, dried and reused So be careful in buying an ERV core which cannot be washed It will be very costly if ruined Very sorry I bought an ERV(especially from Venmar, no support what so ever)

I hear ERV’s raise the RH in homes
Comment from : @sp1200M3D

How long does a erv-core last? I imagine that mold could be an issue
Comment from : @hassiaschbi

Unfortunately ERV is so noisy
Comment from : @ilya8918

Thank you for your video I live in MD and want to have an ERV installed I'm worried about the air intake side of the core building mold due to humidity air coming into the unit Did you see this type of issue for ERV? I saw someone complained about it online
Comment from : @wewe5dfbb

I have an ERV in the Midwest… fight air being too dry in the winter and way too humid in the summer

Biggest waste of money in my new house Noisy Expensive Energy hungry Basically a very over priced fan Its a scam Its just a Greenwashing Scam Some one is getting rich and ERVs are a bunch of green hyped BS
Comment from : @lawrencebarnes6893

Honestly, you must be scared to go outside in case you get a humidity spikereallya shower should kill you on contact I assumethis whole ERV HRV crap seems like a money making thing
Comment from : @Voidy123

Question would an ERV be of any value in ventilating a non conditioned crawl space vs simple screened vent holes Would UVC LAMP be good enhancements to maintain a better environment within them I never enjoyed entering dusty insect ridden crawl areas
Comment from : @charlespaine987

I live in climate zone 3B, hot and dry, but I'm coastal with little to no real humidity and a more of a mild climate because of the location to the coast I got a quote from Zender, and they called for an HRV What do you think in this scenario, ERV or HRV?
Comment from : @bretcrutchfield5622

I just swapped out my HRV to an Venmar N series ERV I’m in Victoria BC Which is the most mild climate in Canada My install is challenging in that it’s an attic with some decent runs of of flex I’m going to rearrange it a bit and replace some of the flex with metal But the auto balancing feature seems to work well, and as an added bonus, the supply from the ERV is going straight into the 8” line that runs to my Bypass HEPA system 👌
Comment from : @JordieG8

I am in Maine with a tight house with humidity problems in the winter- it becomes TOO humid and the windows condensate I am about to purchase an ERV to get some fresh air in and stale moist air out- is this not the solution in this case? Thanks
Comment from : @lesleyainsworth1860

How load is it? I need to put one in my condo so it will be in a bedroom Will it be comfortable?
Comment from : @juliesack2752

Hi it is true that it is not recommended to use ERVs to extract air from the bathrooms? Thanks
Comment from : @markramirezg

What about this case youtube/9MXjsS6J7Cc
Comment from : @ajavrick

What about the argument that the dew point created by the crossing of air leads to mold issues and HVR/ERVs?
Comment from : @joshuaallen7385

Towards the end of the video you mentioned you would comment on one marketing myth, “self-balancing” in a couple of months in another video Did you make that video?
Comment from : @billdenyar4157

I am confused what to do for our house We had some mold issues in the past and want and air exchanger to get fresh clean air inside and get rid of stale/unclean air outside We live in southern ontario in canada Very humid here, but air gets pretty dry in the house when its cold outside, so i don't want to remove even more humidity from the house with the air exchanger The air conditionner and furnace does a good job at keeping the house dry I would say My main goal is to get rid of pollutants in the house Filtration isn't enough really I need to get rid of VOCs from the pollutants, since there is a bit of smell as well Any tips would be great What our tech recommended was an HRV from venmar, i think its one of those self-balancing, which sounds great, but as a telecoms tech, can be skeptical of anything auto Sometimes its great, sometimes awful
Comment from : @W0WHERMY

I live in Northern Canada which means it's colder during winter the temp is around -9 to -40 Is ERV still advisable? Having problem with high condensation on my windows What is your recommendations?
Comment from : @canadalifevlog21

I have a Broan hrv100h what should I be running it on low ? high ? I have no clue on this machine thanks!
Comment from : @bretsherk

Wasn't Brian ultimately not happy with an ERV in his home and moved to a ventilating dehumidifier?
Comment from : @D2O2

Does ERV connect to an existing central air duct system on a finished house? Or is this the kind of thing that needs a whole second duct system alongside the central air?
Comment from : @shoyrushoyru

Does that ERV thingy crackled your voice so terribly ?
Comment from : @-First-Last

Hi I live in Montreal Quebec our summers are hot and winters are really cold sometimes -15 or so do you recommend HRV or ERV My heating is also baseboard electric

Comment from : @mikepict9011

I was thinking of an erv with braided plastic cores increased durability for cleaning Think its a good idea ?
Comment from : @mikepict9011

Comment from : @joebeauchemin

Hi what do i need if my bedroom is really dry and not much air?? due too a very small window,,even plants die a slow death in the bedroomThanks
Comment from : @makkavelli3972

Great video, do you happen to know a product better than the Panasonic WhisperComfort ERV, looking for an spot ERV, and this is the only one i found but i'd like to have more CFM capacity Thanks!

A peak performance video! Thanks, mate
Comment from : @cafekiva7892

I mean, buy a cerv2 and it’ll do it all and far more efficientbrbrThese units came as building since was evolving but it is about 1/5 the solution There are evolutions to this

For Florida what is the best erv de humidifier in the market which does both and connects with hvac
Comment from : @shenoyglobal

I want fresh air in my NJ basement, my plan was to install an ERV and run a dehumidifier I was hoping the ERV would help dehumidify the basement by pulling out the stale moist air, but now i realize i was wrong Is an ERV still my best option or something all together different? I just want my basement to have nice fresh air and keep it from getting stale/moist, it has no windows that open
Comment from : @mark33545

Canada has cold climate ERV (see fantech) dry winters(20-30) and humid summers(50-100)
Comment from : @marcgallant5270

Ever since I had this installed in my house I’ve been getting an odd smell coming from my fence Has anybody had these issues?
Comment from : @Gr8ful7

There IS a more extreme example A Jamaican family lived in Michigan and preferred (endeavored to maintain) hot, humid air, as in their home country This created huge moisture issues in their home - up north, in the cold, in the winter A bit worse than some showers How do you handle this?
Comment from : @DK-vx5co

Are you saying that because most of the day you aren't using the shower, it doesn't matter that you are recycling the humidity from the shower back into the house? And that you could have a humidifier or dehumidifier hooked up to the ERV in order to control for that? I'm unclear about what your main point is
Comment from : @cellocovers3982

Wow so ideally my tiny house would need an hrv, minisplit, bathroom dehumidifier, and air filter?
Comment from : @TheKonnoisseur11

I erroneously assumed that an ERV would be better than a dehu In a spray foam house, I ended up installing a dehu on my dime Lessened learned, ERVs do not dehumidify In a super humid climate like the south, it cannot transfer enough moisture from fresh air to exhaust to break even, you will always net more moisturebrLove the video
Comment from : @timdestasiohvac

Erv for life baby Hrv can kiss my ass Great vid
Comment from : @MrTooTechnical

Thank you clarifying the use of ERV's in the south, particularly Florida I know that it is designed to mitigate humidity, but this is Florida In this state, you learn that not all "stainless steel" products are created equal for a reason Our atmosphere is brutal on machinery of any kind
Comment from : @N8TheSnake

This is a great video One, it takes complex information and tries to simplify it in a way that's conversational, and not talking down to the audience brbrIt also shows, like in science, when new information comes up that supercedes old information, the new information is accepted I caught that comment about needing a dehumidifier AND POSSIBLY a humidifier Humidifiers used to be a four letter word for you lolbrbrBut I still have to admit ignorance about what exactly, besides water, humid air carries that can be so bad for indoor air quality

Living in New York in a ICF home, which would you recommend?

Another great video! Quick Question: How do we properly let in 'supply' for what the clothes dryer pushes out of the house?
Comment from : @cjrob6151

Thank you so much for keeping this clear For the last few years it's been a mess of misinformation or flat out using the wrong terms as people have tried to explain the differences between what these two do
Comment from : @brettzeigerbacher2314

I cut allot of sodium (soda drinks, and chips ) out of my diet I belive it helped my nose bleeds allot
Comment from : @turboflush

Great video on the subject Can you do a video on how to safely humidify a home - tolerances, new air tight homes vs older homes, etc
