Handling hot/cold rooms
Posted on 12/2/24 at 12:40 pm
Posted on 12/2/24 at 12:40 pm
I’m evaluating options for handling hot/cold rooms in my house. My 9 month olds room stays colder than other rooms so I’m having to crank up the heater to warm his room to desired temp (it’s a direct shot down the hall from the thermostat)
This smothers me in my master at night with the heat running (across the house from the thermostat)
It seems like there is about a 2 degree difference in the thermostat temp and his room. My options: 1. close/open vents around the house but I’ve read this isn’t a great idea. 2. Look into window efficiency maybe that’s the problem in the cold room. Other thoughts?

Why not add a space heater ?

I relocated a thermostat that helped balance the temperature.
Mind you, this is in a 2 story house with a 2 story great room, and 2 AC units (upstairs and downstairs) that were fighting each other.

Does your room have a return air path? We had issues with this as well. Turns out if the doors to the room are always closed and there are no returns, the room will always vary from the set temp by 2 or 3 degrees.
Options are cut in a return between the room and common space, or have a ducted return installed after.

Another option is to use, or hire someone with, a thermal imaging camera to evaluate insulation and drafts. One of my friends had a huge area above the ceiling of his kid's room with insufficient insulation.

My advise is not to go crazy over small details. Wear less clothing to bed in the master and have your kids wear long sleeves to bed, first world problems and all.
Serious answer is how much do you want to spend on this? In the winter, you can get the oil space heaters for $50 at walmart. For a single bedroom they are super safe and easy. Then you can move on with life.
Beyond that, getting every room the same has tons of variables.
You need to make sure you have proper airflow if all the rooms are on the same floor. I've seen carpet for example prevent air flow from one bedroom under a door where another had hardwood. Insulation and windows, the direction the rooms face, etc.

Within reason. End of the day I’m not going to break the bank, but this is only one uncomfortable situation. Another is that the room that is my office is what feels like 10 degrees hotter than the rest of the house in the summer. And I work in there 30 hours a week so it’s something I definitely want to investigate.

There should be dampers where the supply duct branch lines come off the mains. Look for a little handle sticking out. They're typically right off from where they branch off of the main.
Assuming you have dampers, I would start with small adjustments and see if it affects things. For instance, see if the one to your child's room is closed and if so of course you want to open it. If its already fully open, try pinching back in the hot rooms to see how much that helps.

If you don't have dampers, have them installed (speaking from experience). Before you do that, get up there and make sure there's no insulation issues.
We had damn near the identical problem. Our son's room would stay colder in the winter and hotter in the summer, and in the winter our master would get toasty just to get his room up to temperature.
I climbed in the attic and noticed that when they sprayed in the foam insulation, since his room is all the way in the corner, the insulation didn't make it over the AC flexline, so a 2 foot portion of his ceiling, closest to the vented soffit, was uninsulated. I bought two bags of insulation and covered it, and that helped some.
Then instead of trying to balance the airflow yourself, get a reputable HVAC company to come and measure and balance each room. Make sure to let them know the issue with the baby's room and they can compensate for that. If you don't have dampers, they will do this when they install them.
Once I added the insulation, we had dampers installed and they balanced the airflow, and that resolved it.

^^^^ this right here, and the only other thing I would add is door vents at the bottom for any door to any room, that usually remains closed. You can get the vents at Home Depot, or Lowe's, and they don't look bad at all.

Great point. Any easy way to check this is to just compare things with door open vs door closed. If its different, you'r not getting the same amount of air into the room because the air has no where to go (not large enough return area).
