Ductless Systems
Report
Those boxy window-mounted air conditioning units might be the old standby, but they can leave much to be desired. They're often noisy, unwieldy, and heavy, and they basically co-opt a window for months out of the year. Fortunately, there is a better solution for home and business owners across Western NY: ductless air conditioning.
