***OFFICIAL 2026 WEATHER THREAD***

The HVAC folks tell me the opposite. They tell me to make sure all registers throughout the house are clear and open.
We replaced the windows in each of our kid’s rooms this year. They do face the west and it has seemed to help a lot. Instead of a 60/70/80 spread from basement to the 2nd story I bet we are only at 75 on the 2nd now.
 
We live in a split foyer house, and with the AC on the temperature differential between upstairs and downstairs seems enormous, especially when it gets ridiculously hot outside like now.

You either sit downstairs with a blanket wrapped around you or you sit upstairs where it's a little warm. I have a large fan at the bottom of the steps blowing the cold air upstairs, but wish there was more I could do to even out the temperature.

If anyone has any suggestions, I'd love to hear them!
We have a four level split and have similar issues. I had a company in that recommended duct booster fans. Never pulled the trigger on that, but on really cold or really hot days, I'm very tempted, as our top level is much colder or hotter than the rest of the house.

 
Talked to a guy who has one by Algona. He said they would rebuild at his place.
They put new blades or a new head on them about every 5 years or so. They don’t like to mention that stuff right away. When they sell them, they say no disruption to the area but they will reshape the area for their pad and drainage will get screwed up.
 
Didn't the 2020 Derecheo record 140 mph west of Cedar Rapids, or was that unofficial.
Unofficial. But my work weather station exploded at 120 mph with the unofficial 140 being like 2 miles away.

If you have forced air heating, leave the furnace fan running 24/7. If the registers are balanced properly, this action should help even the temp throughout the house--may not completely solve the issue but will certainly help. I have geothermal which is slower to correct temperature differences because of the lower temps the furnace operates at, and except for a unit replacement a few years back, my furnace fan has been running 24/7 since the original install in 1995 simply to address this problem
Unfortunately, I have been doing this for a few years now and it doesn't seem to solve the problem, although I'm guessing the temperature differential would be even greater than it is now if I hadn't been doing this.

As someone who was a few miles north of the apartment complexes that completely lost their roofs and had 2nd floor exterior walls falling in, I believed the 140 number.

Thanks! I'm going to do some research on this option. Appreciate the suggestion!
