Frequently Asked Questions About Ductless Mini-Splits in Historic Homes

  • Are mini-splits cheaper to run than old steam or oil radiators?

    Our systems require only a single 3-inch sealed core penetration per zone, avoiding bulky ductwork and protecting delicate lath-and-plaster walls and ornate moldings.
