🔧 Tech Tip Tuesday from Blue Diamond Heating & Air 💎

💡 Today’s HVAC Tip:
👉 Use ceiling fans on low (clockwise) in winter

Why it matters:
This gently pushes warm air down from the ceiling, helping rooms feel warmer and more comfortable without turning up the heat.

A small adjustment that can make a big comfort difference! ❄️🔥
