PVC Window Summer Mode and AC-Reducing Tips Boost Home Cooling

Experts advise homeowners to adjust the small metal roller on PVC window locks to switch to a "summer mode." Turning the roller reduces the pressure on the rubber seal, lessening wear during high temperatures and helping the window close more easily.

To lower reliance on air‑conditioners, specialists recommend using a dehumidifier, which removes excess moisture and makes rooms feel cooler without changing the thermostat. Additional measures include keeping blinds closed during peak sun, ensuring vents and grilles are unobstructed, and running wall fans counter‑clockwise to improve air circulation.
