Why Is Cold Weather a Cause of HVAC Condensation?

The winter season often presents ideal conditions for HVAC condensation to thrive inside your home. It’s simple physics at work: Water vapor present in warm indoor air meets cooler indoor surfaces. Condensation is the result.

Cold Glass Meets Warm-Water Vapor

Condensation is often most noticeable on windows. That’s because the glass surface typically stays cold during low temperatures outside, while the warmer indoor air contains a high amount of water vapor. Condensation forming on windows causes streaking and soaks the window frame and window sills, promoting mildew, mold, and wood rot. Another source of HVAC condensation are the indoor surfaces of exterior walls, which may remain colder in winter weather. Indoor water vapor condensing on these walls can cause paint to peel and may permanently stain drywall.

Lower Humidity = Less HVAC Condensation

Since cold outdoor weather can’t be prevented, the best way to reduce the effects of condensation is to reduce indoor water-vapor levels. To diminish the effects of condensation in your house this winter, most experts recommend keeping indoor humidity around 45%. Here are additional suggestions to reduce water-vapor levels in your home:
