Still have questions? We're here to help.
Call (224) 754-7152Is a ductless mini split a good option for a home addition?
Often, yes — it avoids the cost and disruption of extending existing ductwork into a new space, and gives you independent control over that room's temperature.
How many rooms can one mini split system cool?
A single-zone system handles one room or open area. Multi-zone systems can serve several rooms from one outdoor unit — we'll help you figure out which setup fits your space.
Do you also repair existing mini split systems?
Yes — if you already have a ductless system that's not performing well, we diagnose and repair it in addition to new installations.
