Heat Pump Repair Experts on Long Island
Heat pumps are becoming increasingly popular on Long Island as an efficient year-round heating and cooling solution. Whether you have a ducted central heat pump or a ductless mini-split system, LI Heating & Cooling provides expert diagnosis, repair, and installation throughout Nassau and Suffolk County.
We service all heat pump types and brands — from traditional central systems to modern cold-climate mini-splits from Mitsubishi and Daikin. Our licensed technicians carry refrigerant, common parts, and diagnostic equipment on every truck to maximize first-visit fix rates.
Long Island's coastal climate can be tough on heat pump components. Salt air, humidity, and temperature swings stress outdoor units. Regular maintenance and prompt repairs keep your system running efficiently and extend its lifespan well beyond the average 10–15 years.
