Ductless Mini-Split Heat Pump Installation & Service

Plitnick is a Mitsubishi certified Diamond Contractor®

Since 1977, Plitnick Plumbing and Heating has installed, repaired, and maintained heating systems for Westchester County, NY homeowners and commercial property owners. Our family-owned crew works every day across Dobbs Ferry, Hastings-on-Hudson, Irvington, Tarrytown, Yonkers, White Plains, Ardsley, and the surrounding river towns. We service every heating system common in pre-war and modern Westchester homes: oil and gas boilers, hot-air furnaces, heat pumps, hybrid systems, ductless mini-splits, water heaters (tank and tankless), thermostats, oil-to-gas conversions, and complete heating-system replacements. We also provide thermal imaging energy audits to help you identify where your home is losing heat. Whether your boiler is making a noise it shouldn't, your furnace is short-cycling, or your water heater is leaking, our licensed technicians fix it right the first time. After 47+ years protecting Westchester homes through cold winters, Plitnick is the local heating contractor Dobbs Ferry families call when their heat goes out at 11pm in February.

How Heat Pumps Work:

Mitsubishi Electric ductless HVAC system provides both heating and cooling by using compact indoor units mounted in individual rooms or areas. Instead of relying on traditional ductwork inside the walls, the system connects these indoor units to an outdoor condenser through a small line set. Refrigerant circulates between the indoor and outdoor units, allowing the system to efficiently regulate temperatures and maintain consistent comfort throughout the space.
