Here in Massachusetts and northern Connecticut, our homes experience severe weather extremes. From freezing winter blizzards to humid summer heatwaves, your home works hard to maintain a comfortable indoor climate. While you might inspect your insulation or check your roof, your patio door is often a hidden culprit for massive energy loss. Recognizing the warning signs early can save you hundreds of dollars on utility bills.

Telltale Signs Your Patio Door Is Leaking Energy

Drafts and temperature fluctuations are rarely subtle once you know what to look for. If you walk past your sliding or hinged patio door on a chilly New England morning and feel a distinct chill, the seal has likely failed. Energy-wasting doors force your heating and cooling systems to run constantly, leading to premature mechanical wear and unexpectedly high monthly statements.
