If you think it’s cold now, a mini split in that space will change your life.

[@Itsallaboutthebuild]

I was thinking of getting one of those, but it had a much higher price point. But it would work well in the cold months for heat too 🙌

[@maus0292]

Yep mr cool is best deal but need to make a dust cover for vent. Lots of shop videos on this.

[@Itsallaboutthebuild]

@@maus0292 thanks much will check out 👍

[@volksbugly]

@@maus0292 mr cool is over priced if you don't go with pre-charged lines you can get it alot cheaper. charging lines isn't hard at all!

[@TheSlimHim]

I agree with the mini split but if you must got portable ac, a dual hose system should ahow significant improvements! Your host length is fairly short but ill also mention a general tip dor portables is to insulate the hoses as well.

[@stevec9669]

Surprise to me that HF car moving tool really worked! Great idea👍.

[@Itsallaboutthebuild]

Yes we love the HF wheel dollies. Use them all the time to move the Datsun around. We have a small garage 😁

@@curtishorton6163 thx, much appreciated. We’re all just trying to learn. That’s what we love about YT 🙌🙌🙌

[@KA9DSL]

I used my Flir infrared camera for finding hot spots in my garage while I was installing insulation. Seeing the heat leaks is real neat.

[@Itsallaboutthebuild]

The laser works pretty good, but the infra would be even better. I need to look into the flir

[@marcusandreopoulos3114]

I absolutely love that you guys do projects together! Looking to insulate and possibly floor my garage attic, just too fat and lazy to make it happen...

[@Itsallaboutthebuild]

Glad you enjoyed the video. It’s definitely hard work and I’m glad we had each other to help 😁😁😁

[@jesselejarzar5114]

I had something chew through the plastic of one of those vents.I highly recommend a metal version or at least some small opening wire mesh over the plastic grates.

[@Itsallaboutthebuild]

Wow really??? Will have to keep checking on ours or upgrade. Thanks for the advice 👍

[@Preciouspink]

What is the red tape for? Would double insulating the walls and the ceiling in the loft give equal or better thermal separation from the outside,versus insulating inside the ( building envelope) between the hot second floor from the living area below? Regarding the foil insulation on the garage door. I imagine you unrolling the foil upward from the floor.What were the roll width and length?Did you use two lengths coming together at the middle of the door. I like unscrewing the support lengths putting foil underneath. Has the door operated more quietly or did affect the integrity of the door overall?

[@Itsallaboutthebuild]

Fantastic questions. The red tape just holds the reflectix together at the seams. You could use aluminum tape too. The loft above the ceiling which is now insulated is not insulated, but covered with reflectix material. If we were to insulate the loft you'd need some ridge foam vents too. The reflectix seems to work well in the attic. For the garage we used 4ft wide and as long as we could get the reflectix. The door works exactly the same, no additional noise or signal issues 👍👍👍

[@Michael_Archer78]

I know I'm a weirdo, but if you are doing your own work, I prefer doing insulation, attic work, etc at night. My normal work shift is 7pm to 7am, though, so I'm kinda used to it

[@Itsallaboutthebuild]

Yeah, that probably would have worked better 🤣 With everything else we do I don’t know if I could work the night shift 👍

[@ramoncortez8623]

This is a house of learning doctors

[@Itsallaboutthebuild]

Why thank you 😁

[@scottbrown6034]

A dual hose portable AC would be even cooler, since the heat transfer would completely leave the room. I had one of those single hose AC units, and it worked, but the dual hose is that much more efficient. Alas it costs more.

[@Itsallaboutthebuild]

Ah really? I was thinking of upgrading to a mini split. Will have to check out the dual hose setup. Thanks

[@maus0292]

We had one of those for a while. But ultimately did not last. Replaced with a mini split. Due to dust we killed one. And read on our 2nd mini. Not fond of the filter stem. Need to build a filter box like folk that have them in wood working shops make. The filters prevent dust from killing the mini split.

[@Itsallaboutthebuild]

Funny you mentioned this because I just cleaned the filter and added another layer of filtration from all the dust. We do quite a bit of cutting/sanding. I think we might upgrade to a mini split over time. What model do you have?

[@benjammin2L8]

@@Itsallaboutthebuildcheck out the TOSOT brand they’re much more affordable. less the price of a Mr cool and they have very good reviews

[@ramoncortez8623]

Great ideas, Do you think a gable fan can help?

[@Itsallaboutthebuild]

Yes, I believe it would definitely help move all the hot air out of the attic space.

[@scottbrown6034]

No, that will disrupt the flow from soffit to ridge vent. With a ridge vent, which was clearly visible in their Reflectix video, you don’t need a gable fan.

[@Itsallaboutthebuild]

@@scottbrown6034 so as long as there’s good air flow through the ridge and the soffit no need for gable?

[@scottbrown6034]

@@Itsallaboutthebuild Correct. The gap you left behind the Reflectix, I’m assuming since I haven’t been there, actually runs from the soffit to the ridge vent. It will act as a channel, allowing hot air to escape the ridge vent, allowing air to be brought in via the soffit. That’s how a vented attic works. If you did NOT have a ridge vent, then yes gable fans, or other attic fans would help.

[@Itsallaboutthebuild]

@@scottbrown6034 got it. So no additional vent fan needed in our case. Thanks 👍

[@kevinmills5293]

The problem with those portable units is the hot air that is expelled comes from within the room you are cooling and has to be replaced (normally with hot air from outside). A mini split will make a huge difference.

[@Itsallaboutthebuild]

Right on, I think we’re going to upgrade to a mini split. Any suggestions on best brand???

[@kevinmills5293]

@@Itsallaboutthebuild can’t really help on brands as I live in Spain. I’ve got a Mitsubishi mini split and it’s been very good but I think there are more efficient options out there these days.

[@Itsallaboutthebuild]

@@kevinmills5293 NP, thanks 👍

[@Pallidus_Rider]

One thing people have forgotten, is the exterior color of the building. The color white will reduce temperature as opposed to a darker color, which is better suited for northern climates

[@Itsallaboutthebuild]

Absolutely. It boggles my mind why shingles are mostly darker colors 😭

[@Pallidus_Rider]

@@Itsallaboutthebuild I thought I would mention it, even though you have a light color on exterior of garage. Incidentally, I will be doing the same for my garage, but will wait for cooler weather 😲

[@Itsallaboutthebuild]

@@Pallidus_Rider yes, wait for cooler weather. Not sure why we put ourselves through so much extra pain 🤣

[@-GrimEngineer-1337]

Use a dual hose ac unit or a wall mount mini split unit. Single hose systems are poor because they create negative pressure in the cooled space when they blow air out which sucks in hot air from outside through cracks and crevices.

[@Itsallaboutthebuild]

Will have to look into a dual hose unit or perhaps a mini split… It’s hot out there 🥵

[@Clouds-su3dc]

One more very good option you can do is paint the outside of your garage surface white because white reflects a lot of sunlight compared to a darker colour garage that absorbs heat and makes things hotter. Having your outside garage white can keep the temperature of your inside garage 11 to 17°C/20 to 30°F cooler automatically. 👍

[@Itsallaboutthebuild]

@@Clouds-su3dc love that idea. Too bad our HOA dictates the color of our shingles… but they do let us install solar panels. Thought was solar panels could provide shade and some extra power 😁

[@Clouds-su3dc]

You can try a lighter colour also for option number two but it’s not as heat reflective as white but it’s still very good heat reflector. 😊

[@Clouds-su3dc]

Yes, solar panels providing shade also with a lighter colour outside garage still reflecting some heat, even if it’s in the shade

[@Itsallaboutthebuild]

@@Clouds-su3dc now just have to find the best cost solar options 👍

[@rayv43]

Did you see any degradation in your garage remote signal?

[@Itsallaboutthebuild]

Great question. Haven’t had any issues or what seems to be like any differences in our garage remote opener. And we’ve had this up for over a year now 👍

[@Preciouspink]

Excellent question. Did they insulated the loft walls also,and what were the considerations for the ventilation soffits?

[@Itsallaboutthebuild]

@@Preciouspink Only the ceiling parts were insulated. The loft in the attic of the garage has reflectix material stapled on the rafters with ventilation of soffit to ridge exposed. Check out kzbin.info/www/bejne/d5jMYmSpl82Wn7c

Seriously considering a mini split upgrade. What model do you use/recommend???

[@volksbugly]

There is another youtuber named Will Prowse he has a mini split video. He mostly talks about solar, but that video makes it affordable.@@Itsallaboutthebuild

@@volksbugly awesome. Will check it out. Thanks!!!

[@patrick5028]

Just buy garage door with insulation

[@Itsallaboutthebuild]

@@patrick5028 most homes already come with a garage door, so we didn’t want to just buy another complete garage door for insulation.
