How Do You Know If You Have Drafty Windows?

Windows complete the look of your home and bring fresh air and natural light to your indoor spaces. When they are in poor shape, your comfort could suffer. Window drafts can cause warm or conditioned air to escape, making your HVAC system work harder and consume more energy. Discover signs of this issue from a local window replacement expert. 

Drafty Windows

Visible Damage

Check your windows for visible damage. What’s the condition of the interior frames and exterior weatherstripping? If they are in poor shape, they are likely allowing outside air inside your house. 

Condensation Inside Window Panes

Whether you have casement or sliding windows, they could fog up when there’s a significant difference between indoor and outdoor temperatures. For instance, you might see condensation on your windows while your heating system runs in winter. If you can’t wipe the condensation on the glass, seal failure has likely occurred. When this happens, outdoor air will infiltrate your living space. 

Breeze Around Windows

When you go near your windows, do you feel a cool breeze coming through them? You know you have drafty windows if some areas of your home are more difficult to heat or cool than others. Old units with deteriorating frames are more likely to cause this problem. 

Increased Energy Bills

Are your energy bills rising? Drafty windows could be to blame. Because of them, your HVAC system will exert more effort to reach your desired temperature. Aside from increasing your utility costs, they can make your equipment prone to malfunctions.
