Ductless Mini-Split System Service

Say you live in a condo, or an older home that does not have the air ducts to make central air an option. If this sounds familiar, you will probably need a ductless or mini-split system. Mini-splits offer heating and cooling relief in individual rooms, so you can stay comfortable without having to worry about retrofitting your space for ductwork or using unreliable heating and cooling options like fans and space heaters.
At Weis Comfort Systems, we offer a full range of repair, installation, and maintenance options for ductless and mini-split systems, so no matter what kind of home you have, you can always stay comfortable.
Today’s mini-splits are more energy-efficient than ever, so if you need to upgrade or make the switch, contact our St. Louis cooling pros at Weis Comfort Systems today!
