Curious what noob questions you asked.

Well, it's AC season at my house. Kids bedroom was still 23c with the windows open at 10pm last night. Stupid infill are hard to cool down.
Now we enter the season of it being freezing at the breakfast table. Good times.

The HVAC in my house sucks as well. Cooling the upstairs to ~21 means the basement is absolutely freezing. Our media room was ~15 last night when we were watching TV.This quote is hidden because you are ignoring this member. Show Quote
Although, given it's a wood-frame house that's nearly 50 years old it's probably nearly time to bulldoze and rebuild.

This house has always been weird for temp differentials, even with furnace fan running 24/7. Whatever, we've learned to live with it. Next house will have 2 furnaces and AC only for top floor with bedrooms.

Have you tried rebalancing the vents? Closing the ones downstairs and fully opening the ones upstairs?This quote is hidden because you are ignoring this member. Show Quote

yes. I adjust the vents every spring and fall to get the heat or cold to where I need it.

I'm interested in this. I've always figured that if you open your basement windows and put the fan on continuous that it would circulate that frigid basement air around. But there seem to be many things in HVAC that are counter intuitive.
I can confirm that exploitng natural convection seems to generally be a good idea. I've had good luck with opening an attic hatch and a basement window, but only after the outside temp has cooled below the indoor temp. The hot air absolutely pukes up into the attic and the cold air floods into the basement.
Do this during the day, (because you forgot to close or in the morning) and your house will hit 29°C!
My last house was extremely similar to yours. Skylights and massively high ceilings on the top floor absolutely fucked the HVAC.This quote is hidden because you are ignoring this member. Show Quote
2 dedicated zones is what those houses need and very few of them have them.
I’m pretty lucky in this new place, the whole house stays pretty stable ( with 15min/hr fan scheduled )
I highly recommend these ecobee sensors though, and put in some intelligent programming on which sensors to use when. For example in the evening, DO NOT average in the basement in determining if AC needs to be on. That setting only looks at the bedroom sensors.

Anyone have experience with room AC units? My kids room heats up during the day and even tin foiling the windows like a drug dealer doesn't keep it below 25-28 C
What size is the room?This quote is hidden because you are ignoring this member. Show Quote
What kind of window do you have? (does it open up or does it slide left/right)
Is the window south facing? or what direction
Have you blocked air flow with a door sweep?
Can sell my 12,000btu portable if you're interested.
Also have a 5000btu window unit.
Otherwise I'm gonna wait til July to see if I get more interest on kijiji that way.
Speaking of this whats everyone ecobee setting now that we have sweet, sweet A/C?This quote is hidden because you are ignoring this member. Show Quote
- Switch to COOL mode and just set the temp to +22c and only look at upstairs sensors?
- Add in evening comfort setting to lower the temp a degree or two more then during the day?
- Run AUTO mode? Seem silly to have the furnace pop on for a couple hours one night if it gets really cold outside.
It works. We did this for my daughter for two summers before we got central AC.This quote is hidden because you are ignoring this member. Show Quote
Pro: Very easy to control temp of the room. Set it and forget it.
Pro: Low cost of entry. <$400
Con: Probably a stop-gap, and you'll want central AC at some point
Con: Uses just about as much power as central AC (or mine did at least), if you care about that kind of thing
Con: Takes up floor space and is ugly
Room is probably 200-220 sqft or soThis quote is hidden because you are ignoring this member. Show Quote
3 large windows facing east, they open about 20 degree maybe (dont slide, just open out with a crank)
Have not blocked air flow

My settings that i use 365 a year. I feel like I keep my house warmer than many. Meh.
I use auto during bridge seasons, what seems silly to me is the very small amount of cost it adds to just have the house at the temperature I want. I feel like usage costs are a near 0 portion of my bill.
If the temp dips below 0 auto gets turned off which can be a bit annoying, by June I’ll probably switch it to cool only.
22C seems really cool to me and your AC will run ALOT, but I’d be lying if I said I didn’t manually override to 22 sometimes. 24 is the level where I never feel like my house is too warm.

Sometimes it's not about the expense, but the feelings. My feelings burn when I use heat and cool in the same day. That's a mental block I apparently cannot get over. Could be because my AC is undersized and struggles to cool my house properly. Oh well.

Yea I haven't actually used the a/c yet so no idea if 22c is too cold but we'll see this weekend i suppose.
I'm also having trouble getting equalized temp from the main floor to upper floor for some stupid reason. Fan has been running all afternoon at I'm still seeing +16c main floor and +19.5c upstairs (those temps are with no a/c as well, just opened the windows last night). Seems like running the furnace fan cools the main floor and doesn't do fuck all upstairs.
And ExtraSlowPoke is right, I'm not running AC and heat on the same day. I'd hate myself.
Is it an infill? If so that is life. Pick comfortable upstairs bedroom, or not frozen basement. I’d shut damn near very basement event.
I find I don’t need to cool to nearly the same temp I heat to in the winter.
AC is a godsend. People who say we don’t need it in Calgary are just wrong.

Nope. 2 storey with huge south facing windows upstairs that cook from sunrise to 3pm. 2018 build so shits tight. I'm going to mess with closing vents in the basement (duh) and main floor to see if that helps.This quote is hidden because you are ignoring this member. Show Quote
I’d invest in the extra ecobee sensors too to help steer the thermostat. I found they helped a lot at the margins.
I personally would not own another 2 story plus basement home without 2 true HVAC zones. This is not nessecsrilly a popular opinion but I think it’s an accurate one.
A skinny infill just exacerbates the problem.

Is the heat due to big windows facing the evening sun? That's why our West-facing bedroom still gets warm in the evening despite having A/C (though it's definitely better than without the A/C). If so, you might look into getting some tint - that's what we're doing and since it's very obvious that big window is where most of the heat is coming from (I've measured 50C behind the blinds on a summer evening), it should help a ton based on what the tint guys are telling me anyway. The film goes on the exterior and apparently rejects up to 90% of the solar energy.This quote is hidden because you are ignoring this member. Show Quote
It's way cheaper than A/C so it might be something people who don't yet have A/C want to try before shelling out $5K for A/C. My quote was around $500 for a large window and you probably only need to do the windows that bake in the sun toward the afternoon/evening or the bedrooms.
