I already have an HVAC system in my shop, and I am planning to add this. Will it increase my costs or use a lot more energy?

Not at all! The Titan is highly energy-efficient, using far less power than multiple smaller fans or just your HVAC alone. Many facilities see up to 30% savings on heating and cooling costs because the fan keeps air evenly circulated, cooling in the summer and pushing warm air down in the winter for better comfort and lower bills.
