One local team for every heat pump need
Installation, conversion, repair, and maintenance for homes across Nassau and Suffolk County, handled by a team that works with heat pumps every day.
Whether you are replacing an oil boiler, fixing a system that stopped heating, or adding comfort to a room your central air never reaches, GreenShield Heat Pumps covers the full life of your system. We design and install new heat pump systems, convert oil-heated homes to efficient electric comfort, repair equipment of all major brands, and keep systems running with seasonal maintenance.
Every service starts the same way: we listen to what is happening in your home, look at the house and the equipment, and explain your options in plain language with a clear written scope. Choose a service below to see how we approach the work, what is included, and answers to the questions homeowners ask most.
Move your home off heating oil with one coordinated project that covers heating, cooling, hot water, and electrical planning. We explain full and phased conversion options before any work begins.
Go to Oil to Heat Pump Conversion →Zoned comfort for additions, bedrooms, finished basements, and whole homes without usable ductwork. Every zone is sized and placed around how the room is actually used.
Go to Ductless Mini-Split Installation →No heat, weak cooling, ice buildup, water leaks, or repeated error codes? Our technicians diagnose the cause, explain the findings, and complete the repair with your approval.
Go to Heat Pump Repair →Seasonal cleaning and inspection for ducted and ductless systems. Maintenance protects efficiency, catches developing problems early, and builds a useful service history.
Go to Heat Pump Maintenance & Tune-Up →Central, ducted heat pump systems matched to your home’s heating and cooling loads, duct capacity, and electrical service, with cold-climate performance planned from the start.
Go to Air-Source Heat Pump Installation →Efficient hot water from a heat pump water heater, sized around your household demand with proper space, drainage, and electrical planning.
Go to Heat Pump Water Heater Installation →That is common. Many calls start with a symptom, like an uncomfortable room, a rising oil bill, or a system that short-cycles, rather than a specific service request. Describe the problem and we will point you in the right direction, whether that turns out to be a repair, a tune-up, a single ductless zone, or a full system replacement. Call (516) 874-2060 or request a free estimate and we will take it from there.
