Problem: My central heating at home heats upstairs, but not downstairs. Anyone know why?

Answer 1

im not being a porky mouth, but heat rises. if you have a forced air system, you can close down the upstairs vents, at the same time make sure the down stairs vents are open.

this will force the heat down stairs....you may have to tweak thing around a little, but it will help you out.

remember to open the upstairs vents when its A/C season. you can try closing down the down stairs vents in the summer, but be careful, the reduced air flow will freeze the a/c evaporator coil on a high demand day.

Hope this helps,

Answer 2

There may be small vent cut-off's located in the ducts that are shut off. Every change of the season, I have to go around the house & open & close these little shut-offs to evenly distribute the heat or the airconditioning.
For example: in summer, I close off the basement ducts because it's always cool in the basement anyway, & then there is more cooler air for the upstairs. But in winter, I have to open those same vents back up, or freeze out the basement.
So you may have recently moved in, or you have forgotten about these vents like I do every year until my frozen feet remind me where I have gone wrong.

Answer 3

I once owned a 2,600 sq ft two story home with the same problem. I was told that two air/heating units were needed, one upstairs and one downstairs. If your home is an open floor plan with a loft, it may help to turn your ceiling fans on reverse. Remember, warm air rises and cold air falls.

Answer 4

1 check the filter 2 check all heat outlets in each room that they are open 3 check all return air openings are not blocked 4 check duct for a closed damper assuming this is forced air system

Answer 5

You may have a dual zone system (we do); it is set up for different temperatures for different floors. Your thermostat should tell you if it's dual zone.
