Why Certain Rooms Run Hotter Than Others

When a room feels hotter than the thermostat says it should, the issue is often less about the AC and more about what the windows are allowing in.

A window does not have to be broken to be inefficient, because weak seals, thin glass, and worn weatherstripping can all raise indoor temperatures.

A few common signs point to the windows:

What To Watch For During Replacement

A good installer will look at the whole assembly, from the sash and frame to the insulation gap around it.

What glass package is being proposed for the sun exposure on this side of the house? How will the installer air-seal the opening after the old unit comes out? Is the project a full-frame replacement or a pocket installation? What does the warranty cover on the glass, frame, and labor?
