Following these tips helps Old Westbury homeowners extend equipment life and reduce energy costs.
Schedule your AC maintenance in April or May before Long Island's humid summer arrives. Early tune-ups ensure your system is ready for peak demand and can prevent mid-season breakdowns.
Keep outdoor condenser units clear of debris, leaves, and vegetation. Allow at least two feet of clearance around the unit for proper airflow—especially important for homes near Old Westbury Gardens.
Use ceiling fans to supplement your AC. Running fans counter-clockwise in summer creates a wind-chill effect that lets you raise your thermostat 3-4°F without sacrificing comfort.
Close blinds and curtains on south- and west-facing windows during peak afternoon heat. This simple step can reduce your cooling load by 10-15% in Old Westbury homes.
