This Mechanical Room is Epic : Build VLOG

This mechanical room is bigger than my whole house. I’ve installed many of those Mitsubishi units.

You need the humidifier on those cold dry winter days and nights. You can run on a rug And with static electricity you can give one hell of a shock if you don’t have a Humidifier.

[@zjeepgozweeln]

You would be surprised how little to no humidification you need on a really tight house. Just the moisture from breathing, cooking, and bathing can be enough or even too much. On a standard leaky house it's the cold dry winter air constantly infiltrating that dries out the indoor space.

[@arcanondrum6543]

@@zjeepgozweeln All the air inside a tight home is replaced via the HVAC by outside air (Matt Risinger covered that). Outside air is dry. That's a great deal of volume with little moisture.

[@michaelmcewan5074]

Extremely nice system and wisely designed. With the amount of mechanical refrigeration connections involved with that type of system the potential for refrigerant leaks is high so having the accessibility to make repairs is critical. Very impressive installation. I come across those types of HVAC systems here in Virginia and the builders tuck those refrigerant branch boxes in unserviceable spots within the home so when leaks occur it’s a major repair. Thanks for the great content. I’ve been an HVAC tech for 26 years and I greatly appreciate serviceable high tech installations. Installing the latest and greatest HVAC systems is one thing but putting the thought into making it serviceable is very impressive. Kudos!!!

[@dougandjyness]

I own an HVAC company and we install this Mitsubishi product every day.....the main down fall of this system is the type of AHU's they used....those pancake AHU's are a disaster to change a coil or fan blower motor.....literally open heart surgery. It would have just taken an extra 8-12 inches to put in the Horz AHU's that have standard A coils and blower motors. It also looks like they had the space. This is the definition of just following the drawn spec rather that pushing the Mech Eng into what he should have drawn. Other than that this is a stellar ductwork install.

[@michaelmcewan5074]

@@dougandjyness Agreed, those pancake airhandlers are terrible to perform repairs on and homeowners always assume it’s not working correctly because of the lower CFM.

[@rebturtle]

As an electrician, I'm both happy with the neatness of the distribution panels, and mildly curious/ nervous about the effects of bundling those cables ( typically only an issue if done for longer than ~2' due to heat buildup and EM reactance ) and how they were landed into the panels.

[@steven7650]

Carrier now has a 6 port branch box for small residential builds. I'm considering it.

[@bobainsworth5057]

With that space, you can build a large model railroad😄

[@valkyriefrost5301]

My first thought when I saw that room was someone is going to fill that room with stuff that can't be easily moved (like an extensive model railroad) or they'll put in a hard ceiling for even more "living" space. Then, when one of those systems needs repair, the HVAC guys will not be able to get to them as the home owner has literally blocked the access...

Matt, I see a bunch of low voltage stuff. I would have loved for you to talk about the structured cabling. I notice that structured cabling seems to still be an afterthought for most if not all builders still.

Those are sweet systems, with those covers on the outdoor units it can go down to -47 degrees.

[@WeAreTwoDoorsDown]

I assume you mean the black boxes with yellow wires coming out the top? If so, those are actually relay boxes for automated lighting, fans, blinds, etc. But I would sure hope a home of this caliber would have a well thought out networking system as well.

[@snowgorilla9789]

Up here in Canada I hear a lot of complaints about the running costs of heat pumps, they say they installed them to save money but the electric bill has gone WAY up. These are just conversations I have overheard numerous times from different people and did not get any specifics so maybe cheapy units or bad installs or both ?

[@seabream]

Well what did they start with? If they switched from natural gas, propane, oil, coal, wood, etc... then of course their electrical costs will have gone up substantially because they are using electricity instead of combustion for their heating. The relevant question would be how that increase compares to their decrease from the previous system. Now, if they were changing from electric baseboard convection, radiant, or (somewhat rare in Canada) a hydronic system with an electric boiler, and their electricity usage went up, then that's more of a problem. From my own experience in southwestern Ontario, energy costs have been roughly a wash before and after getting an H2i Mitsubishi Zuba system (and at only a small increase in price installed for replacing a furnace and air conditioner of similar capability - which to be fair, is comparing with a premium Trane system) but there have been other benefits. Also, if I were to make comparisons into the future that wouldn't necessarily stay that way since different energy sources change prices at different rates. As an example, in Europe, electricity and natural gas prices for households both went up this winter as compared to the year before, but natural gas went up much more.

[@beachboardfan9544]

Can any HVAC ppl in the comments explain to me why its called static pressure instead of just calling it resistance? Its literally the duct circuits resistance to flow right?

[@Ariccio123]

Because there are dynamic effects too.

[@beachboardfan9544]

@@Ariccio123 Can you elaborate on that?

[@Z50paintballer]

@@beachboardfan9544 not really in the vein of HVAC, but dynamic pressure is related to changes in the flow when flow starts and stops, which causes a pressure gradient across the length of the duct. Normally static conditions are studied for system design, and other factors can be neglected.

HELP! ok...this is a long shot, but lots of smart people in here. whats the proper way to insulate an A frame home? we dont have much access to spray foam and im not sure about how the venting works correctly. i was going to eliminate the venting, hopefully, by installing a zip r panel on the roof deck, tape, and seal everything up. Then maybe some batts inside. the framing should be 2x10.... thoughts?

[@davidchillton1744]

Consider mineral wool insulation it doesn’t loose r value over time and is very water resistant and won’t mold, not to mention extremely fire resistant. There’s no proper way to insulate a home per say, but definitely ways to do it wrong. If your trying to make the most energy efficient house possible minimize any penetrations in walls and on through the roof. If your using the zip system liquid flash in my opinion would definitely be a more permanent air sealing and would get into the seams more and provide a better seal. Not sure on your climate or roofing material your going to use but consider having an air layer to allow some ventilation beneath it if necessary to prevent any condensation issues. Overall air sealing any and all seams will minimize energy loss, and insulate any can lights (if you have any).

[@davidchillton1744]

This is rafter framing I presume?

[@R2Mike]

@@davidchillton1744 I'll stick build the whole thing but the framing was 2x10. I just didn't know if the fiberglass against the osb would cause any rot. Using baffles would be really time consuming, so I thought the r panels on the outside would basically be like using spray foam on the inside. It will have a metal roof as well

[@alexisstarsmith1477]

WRONG! Flex pipe on supply lines (=quiet & filtered supply) and only ridged on returns for cleaning unless you have filters at the return inlets then yes flex duct returns. I love forced air as a filtering method however I've considered hot water based radiators at outlet points because you can control each room as it's own zone independently or incorporate a whole house zone controller. Each room adjusted by occupants use or common sleep temp. A side room kept @ 45 on heat because or 90 on AC because it's not used or storage. Filtered house, independent/user temp zoned per room or centralized controller defined heat/AC.

[@alexisstarsmith1477]

To refine - each filtered outlet could be hot or chilled water based on user or central based profile

gah damn. that's one expensive job.

[@nikdipetta]

True. But Still good tips and tricks you can do. Heat pump systems are affordable. And designing the house for conditioned mechanical and rigid ducts will add costs sure, but it’s ultimately up to owner and how they want it built and how much they want to spend. Vs how efficient their home is. This is obviously a very high end build. Hopefully it trickles down and become more affordable for mid range homes. Eventually lower priced builds as well. Like I said heat pumps are available on the cheap systems now.

People are seduced by finishes when that could be done, slowly by an owner. Structure, Insulation, Mechanicals, Kitchen and Baths are where the money should go. The money will be paid back forever.
