I guess. From outside or in the attic?Do you think you’re capable of determing type / size / area of vents?

I dont understand the point of pegolas. No protection for user from rain and very limited shade protection,Put a deck/pergola in backyard
If it’s me, I start outside to determine type of roof venting, then move inside w a tape measure to get dimensionsI guess. From outside or in the attic?
Curious - the house you bought doesn't have gutters?Have rain gutters installed
Install quartz countertops in kitchen
In a word: Vines. Something like this to provide natural shade:I dont understand the point of pegolas. No protection for user from rain and very limited shade protection,
Yeah there are several houses in the neighborhood without rain gutters, which I dont get, especially here in Florida where we get TONS of rain.Curious - the house you bought doesn't have gutters?
Quartz freaking rocks for counter tops![]()
Mine provides pretty substantial shade. It’s the difference between being able to sit outside and not during a good chunk of the summer. Plus ours is near a bunch of windows and keeps the house cooler.I dont understand the point of pegolas. No protection for user from rain and very limited shade protection,

The gutters are #1 on the list and will be done by the end of the month.
The one negative about quartz form what I understand is that heat can damage the resin so youve gotta use hot pads and not set pans directly from the oven on it.
Photo of concrete feather finish?Built our house 3 years ago. Hated all of the finishes available to us for the wet bar in the basement, so went with the cheapest options.
Just finished redoing:
Also repainted kid's bathroom cabinets grey and installed carrera marble double sink vanity top with new undermount sinks and widespread faucets.
- Painted cabinets grey (including built in wine rack - pain in the ###)
- Wrapped bar in wood (thick laminate flooring - super easy and turned out great)
- Backsplash
- Concrete feather finish on bar and counter tops (was going to pour solid concrete, but figured what the hell. For ~$100, let's see how this turns out. Love it)
Next up:
- Upper cabinets and waterfall counter over washer/dryer in laundry
- Aerate and slit seed the lawn end of September-ish
I guess I don't have any photos after I added trim around the backsplash, touched up all the wall paint, added a final "wet look" coat and moved the bar stools back. When I removed the tape from the wall it peeled away some paint. I'm guessing because I let the feather finish dry before removing. Really, you can do all of the layers in one day (I did 4), but I did this over the course of 4 days late at night while the kids slept. Super easy to do.Photo of concrete feather finish?
OK...Determining the amount of airflow in cubic feet per minute (cfm) that the whole house fan should provide involves a simple calculation. Multiply the total gross square footage of the house (include upstairs area) by the ceiling height (typically 8 feet). Select a fan that delivers between one half to one times that amount of cfm at 0.1" static pressure. For example, a 25'x40', one-story home is 1,000 square feet and would need an 8 x 1,000 x 0.5 = 4,000 cfm fan or better. A manufacturer sells a two-speed unit that delivers 4,500 cfm at the high setting (240 watts) and 3,200 cfm at low (120 watts); this unit should be adequate
last step is to ensure you can exhaust that air out of your attic. Determine what venting you have there, size it, come back here and post and I can check it
When you talk HVAC you talk air changes per hour. How many times per hour you want to turnover the air.shuke said:OK...
House is 2275 sq ft with 8' ceilings so 18,192 cub ft.
Attic volume is 2,080 cub ft.
Venting: I have nine 8" cylindrical vents for 3.1 sq ft and approximately 98.7 sq ft. of perforated vinyl soffit vents that have a net free area of 5.87 sq in per sq ft, so this is another 4 sq ft of venting giving a total of 7.1 sq ft.
Looking at these models, the CL-5400 covers up to 2520 sq ft and requires a minimum of 6.7 sq ft venting. So I am assuming this is the best fit.
Not sure why the values on Amazon are different. That says the CL-5400 covers up to 2725 sq ft and requires 7.3 sq ft of venting. I'm assuming I'm fine either way.
However, the airflow on this is 4332 CFM, and your post is saying I need something that delivers twice that. Where is your info from?
Well the way I see it is this... you’re not trying to move attic air. You’re trying to displace house air with external (environment) air.After more research not sure the Quietcool is going to move enough air. Thoughts on best way to add more attic ventilation? Gable vents?
I see what you're saying, maybe there is a disconnect. I want to both displace inside air with outside air but also displace the hot air in the attic. Whole house fans are typically mounted in the ceiling to do this.Well the way I see it is this... you’re not trying to move attic air.

If you mount this fan fan on the gable it will exhaust directly outside through the gable. You then need to connect that fan to your house. You can build a simple chase with plywood or you can duct it, but you want to “bypass” the attic and push that house air directly outside. In this way attic venting is irrelevant - you just need to have a few windows open
Honest to Dodds...After more research not sure the Quietcool is going to move enough air. Thoughts on best way to add more attic ventilation? Gable vents?
Brilliant!
Do some research on attic fans - they are a losing game. Ie you put more energy in than you get out. Protecting your home from heating via the attic is achieved by insulation, not by blowing that air out.I see what you're saying, maybe there is a disconnect.

Your link is talking about powered attic exhaust fans. Those run all the time even when the A/C is on so can pull cold air from the home into the attic, which can raise your energy costs. That's not what a whole house fan does.Do some research on attic fans - they are a losing game. Ie you put more energy in than you get out.

Make sure you are airsealed and well insulated. Insulation is cheap and if you don’t have enough that is your best bang for your buck. Whole house fans are designed to displace house air with outside air.

That's why I was looking at the Quietcool models because the fan is listed and not sitting right on the joists. Like I said, one we had at our hold house was like one of those belt-driven Dayton models, very effective but very loud.No sweat buddy. There's a "Like" button the posts also, feel free to use liberally
I personally would bypass the attic as possible, commingling the air is just a complication in my opinion, but good luck either way. If you do decide to put the fan in the ceiling see if you can 'hear' how loud an installed fan is first (and wife), to make sure you won't hate it at night.
I gotta look into this. Wife and Kids "forget" (aka just don't care) to turn the vent fan on when taking showers. They open up the door after showers and it's basically a steam roomWhile I was working in the master bathroom I replaced the non-working exhaust fan. I don't know the brand but I got it from Costco. LED light (very bright) and multi-function fan, it's really cool. So if you keep the fan switch on it has a moisture sensor and will just automagically start working as it senses moisture or you can turn the fan switch off and back on to go full manual mode, I keep it on all the time. How do you tell the difference? There's a tiny little LED light up in the fan. If it's off, it's off. If it's blue it's in auto mode. If it's amber it's on manual. How cool is that?
lol... I installed a motion activated fan.I ripped and replaced our neo angle shower door. . . I had no idea that it was called that but I know now that I replaced it. . . thanks google! It's two pieces of side glass with a glass door, I wanted to go with a frame-less door but I chickened out and bought one with a frame around it. This project took me two months. One month because I had to order it and wait. And another month because every single time I started working on it, I got interrupted but this past weekend I finally finished installing it, caulked it on Labor Day, waited two days (just in case) for the caulk to fully cure/dry and used it for the first time this morning. So it had been a couple of months since I used that shower, it was a nice feeling! We had been using the shower in the guest bathroom which was kind of a pain.

Replaced the toilet seat while I was at it for extra bonus. So, now, you can sit in the bathroom on the new toilet seat, turn the fan on and admire the new shower door!![]()
Yeah, I need to install one of these in my son's bathroom. The thing is, I just replaced his about 2-3 years ago. It was a really nice (quiet) Broan fan that wasn't exactly inexpensive. The problem is that he NEVER turns the thing on and, of course, I didn't even think about putting one in with a moisture sensor. when I replaced it . . D'oh!I gotta look into this. Wife and Kids "forget" (aka just don't care) to turn the vent fan on when taking showers. They open up the door after showers and it's basically a steam room
Yeah this os the scenario when they actually do remember to turn it on (or i open door and turn it on for them mid shower)I put timer switches on all my bathroom fans - 4 buttons for different time intervals. My issue was the opposite of most of you - my wife would cut our remote fan on the master bath when showering, then forget to turn it off, so we were pulling all the conditioned air out of the house.
Which fan?shuke said:Fan purchased. Can’t wait to get up in my 1400 degree attic this weekend. I’m thinking install shouldn’t be difficult, just a little concerned about the wiring, including running it from an existing outlet and into the ceiling. No experience with that.
Will do some youtubes
I cut my FiOS cable coming in the house & they can't run a new one until Monday. I was doing some landscaping and it was a low burried wire in the way of my new French drain & rock path. I litterally pulled 50ft+ of random coax re-reuns from this area during an earlier excavation, and I thought this was another old one. Despite the wire not being coax
. I realized it when it was tough to cut through with my pliers.
This oneWhich fan?
I thought we worked out that this unit was under-sized? You're going to turn this thing on before bedtime and it'll finally be getting cool by the time you wake upThis one
“are you tying it into your smokes?”
Tell me how
“4 wires right?”
Haven’t opened the box yet
“How many amps, you putting it on it’s own circuit?”
tying into existing 15 amp circuit. Running power from middle of circuit outlet to a new gang box with a 2 speed switch and a timer switch, then running from there to attic.
Rolling with it, bro. We'll see.I thought we worked out that this unit was under-sized? You're going to turn this thing on before bedtime and it'll finally be getting cool by the time you wake up
Yes, hard-wired. Thanks for the advice. I will do this once I have this thing installed.As for the smokes... what I was asking is do you have hard-wired smokes, interconnected? They should have 4 wires coming off them (well 3 plus ground). If you have that, use the fourth wire, take it back to a relay that will shut off your fan. It's pretty easy, the relay should be about $10. Basically the smoke alarms, when activated, will send a signal via that 4th wire that says FIRE. You can use whatever smoke alarm is closest if they are interconnected. That signal wire goes to the relay, and when signaled that relay closes and thus interrupts power to the fan.
edit to add without this a small fire will become a major fire very quickly. for the sake of your family please do this
It's going to be installed in the attic. Are you saying I need to install a light up there? #### that noise.Looks like that's about 5.5 Amps. What else is on that circuit? Probably ok
Edit to add - code probably says this should have a light near it on a separate circuit so that with power isolated, you can still have light for a tech to work on it. Not a big deal but FYI. That came up in my inspection when I added HVAC
Can you link to some recommend relays? I thought the ones I saw were to turn something else on, but not turn it off.https://www.homedepot.com/c/smoke_detector_placement_and_where_to_install_HT_PG_EL
Look at step 6
The red wires are your 'signal' wires. You just need to jump from there to the relay. The relay itself will have power in and power out, it is basically a light switch that is turned on/off via that signal wire.
Relays can do either. Just wire it backwardCan you link to some recommend relays? I thought the ones I saw were to turn something else on, but not turn it off.
