Ductless AC & Mini-Split Systems
Mitsubishi ductless solutions for additions, bonus rooms, and whole-home comfort.
Comfort Without Ductwork — Heating and Cooling for Any Room
Ductless mini-split systems are the perfect solution for homes without existing ductwork, room additions, sunrooms, garages, and anywhere you need targeted heating and cooling without the cost and disruption of installing ducts. As a Mitsubishi Diamond Contractor Elite, Siegman & Schaefer brings the highest level of ductless expertise to every installation in Hanover PA, Westminster MD, and surrounding communities.
Mitsubishi ductless systems are whisper-quiet, incredibly energy efficient, and give you independent temperature control in every room. Heat or cool only the spaces you're using — and stop wasting energy on empty rooms. Whether you need a single-zone solution for one room or a multi-zone system for your entire home, we'll design the right setup for your needs.
Every installation starts with a site survey to determine the optimal placement for indoor and outdoor units. We handle the electrical, refrigerant lines, and mounting — and we leave your home clean when we're done.
