Why is one room of my house hot when the others are cool?

When every room in the house is comfortable except a single bedroom, that’s usually more of a problem with the air conditioning system than with the location of the room. 

There’s no need to swelter overnight when the rest of the house is cool.

Tip: Don't sweat: Get an energy audit. You could discover a problem with: 

  • solar heat gain penetration
  • improper air flow
  • pressure imbalances caused by the inability of the a/c to recruicult air into the air handler
  • insulation failure

The best way to determine what’s causing the problem is to discover the root cause. And the best way to get to the root of any home energy problem is through comprehensive energy audit—before you pay for repairs.
