Testing out a High Performance HVAC Installation

Note John's Electrify Everything shirt. WHICH HE KEEPS FOR HIMSELF. lol Love these guys! Great project!

Nate the House Whisperer that reminds me, I need one!

[@neilcomparetto5282]

Milo Torres if you’re referring to the filter grille we’re expecting changing about every 6 months. As always every house is different.

[@guybeavers6026]

Kudos to Neil and John. If you live in the Virginia are where these guys are located and you're doing a remodel or new build, please consider these gentlemen as they are the best of the best.

[@chargedmtb7440]

I have been installing ERV’s that way for 20 years.

[@HVACS]

I guess it’s not uncommon in some places. I’ve just never seen it in Florida

[@mhoush]

What an awesome video! Great job Neil & John!

[@doughunt6978]

Pretty damn sweet design and install. BZ on the actual testing!

[@neilcomparetto5282]

Doug Hunt thanks Doug!

[@theairconditioningguy]

It does take away time from working. To have to record video. But we HVAC fanatics love this stuff.

[@awesomebillfromdawsonville8715]

This is commercial HVAC standard installation basics. Hopefully a good PM contract is sold with installation to keep systems clean and working correctly.

[@mannytheacguy]

I know you have decent filters plus the ERV but how do you access the evap. coil and blower section for maintenance/service?

[@billj4859]

In the area I work in we don't see systems like this. While I like the specs on it I don't like it at all from a serviceability standpoint. The undercut doors lead to carpet filtration. Is that basically an insulated door covering the indoor coil?

[@neilcomparetto5282]

bill j the combination of leak-free ducts, great filtration, and blower on the warm side keeps the AHU very clean... There is no carpet in this house so that not an issue- I hear you though.

[@billj4859]

@@neilcomparetto5282 very interesting install. I'd like to see a long term update on one.

[@frankgall6]

I’ve watched this video like 10 times now

[@hvacshinobi8047]

Quick question, the DG 700 manometer calculates and displays the actual CFM duct leakage, why was he using his phone to find the result of the test?

[@dennistreacy2160]

I still think using hard pipe on straight runs is easier, than pulling flex tight. This is probably from running hard pipe for the last 25 years. We use flex duct only to pull over the hard pipe to speed insulating the duct.

[@neilcomparetto5282]

Dennis Treacy 10’ and under yes. Above 10’ I think flex is faster.

[@tonymckay9031]

Yeah, that was awesome! Thanks!

[@rj.parker]

Does the Rheem heat pump circulate air from the mechanical room to the crawlspace and then back using a sealed crawlspace? Is the house in this same air space or is the mechanical room sealed separate from the house?

[@johnsemmelhack6294]

The heat pump water heater discharge air is sent to the sealed, conditioned crawlspace. A transfer grill in the floor brings mixed air back up to the house.

[@j.r.1223]

Very cool! Thanks!!!

[@mike7357]

Great video! Thanks.

[@passangsherpa6831]

That’s looks new design not sure but very clean must be new one keep posting new video very nice 👌

[@redhathat]

The crawl space should be forbiden

[@stevebotson7734]

Second 👍

[@spoderman2886]

What’s the maintenance on all that nonsense

[@patolorde]

Erv is innovative? 😂

[@HVACS]

The way they are ducting it is

[@Oscarbm1234]

First

[@embreesmith7613]

cheesey system in my opinion ... undercut Doors ..?? .. nope

[@HVACS]

If cheese works well then give me cheese

[@mattbruner8633]

Cheesey system?? This is in the top 1% of systems installed out there. It doesn't get better than this

[@thebigdoghimself]

I am buying a Rheem heat pump water heater, I was thinking of taking its intake air from a conditioned attic as it is always a bit warmer up there than in the living space. Would there be any advantage to that? I figured it would be easier for the heat pump to transfer heat if the incoming air is warm to begin with.

[@neilcomparetto5282]

John Salazar sure, warmer air will help with the performance of the water heater. Depending on how difficult that is the juice may not be worth the squeeze 🤷🏻‍♂️.

[@thebigdoghimself]

@@neilcomparetto5282 We are rebuilding after a fire. Going from natural gas to a mini split, so we have a flue going from basement to attic that is not going to be used. Since the path is already there should be pretty straightforward?

[@dunkdamonk]

@@thebigdoghimself what else is in your mechanical room? What region do you live in? Alot of time we spec a heat pump water heater to lower the dew point in a mechanical room or basement.

[@thebigdoghimself]

@@dunkdamonk We are in The Chicago suburbs. There will be either 2 LG red or 2 Mitsu air handlers in there. There will be an electronics rack that generates some heat however as a whole the basement is cold. We are installing a radon mitigation system and I have been told that since it is pilling air from under the slab it has a side effect of removing a lot of humidity from the basement.
