Why Are Some Rooms Hotter or Colder than Others?
December 02, 2015
This is one of the most frequently asked questions in home air conditioning and heating. Unfortunately, there’s no silver bullet. There are a wide variety of reasons the temperature of your home can vary room-to-room:
- Rooms can have different levels of insulation
- Rooms can have more walls or doors exposed to the outdoors
- Bad windows that let heat/air escape
- Hot air rises; second floor rooms can be hotter than first floor rooms
- Rooms can be further away from the heat pump or AC unit
- Air vents or ducts can be congested or blocked by dust
And that’s just a start. It’s not an easy problem to solve. Usually, you’ll need professional help to fix this problem, but here are a few things you can try for yourself before calling in a professional:
1) Dust the vents.
Dust could be blocking the vent; make sure they’re all clean.
2) Make sure all your air vents are open.
If one room is noticeably warmer, ensure that the air vent is open. Closing vents can actually increase pressure in your air ducts, increasing duct leakage. Basically, closing vents means you may be air conditioning your unconditioned attic—a huge waste of money.
3) Adjust the duct dampers.
If your air ducts are exposed (likely in your attic or basement), there should be a knob that you can turn parallel to open airflow down each air duct. Adjusting dampers has the same outcome as adjusting the vent, but happens closer to the source.
4) Close drapes and shades.
Closing drapes and shades helps prevent heat from invading your home through the windows.
If you try all of those ideas and they don’t fix the problem, source of the problem probably more complicated and requires a professional to fix.
