We perform heating and cooling load calculations, design the system layout, and select properly sized equipment.
Energy-efficient equipment is selected based on your space, budget, and performance requirements.
Equipment is installed, ductwork or line sets are run, thermostats are wired, and the system is charged and commissioned.
System is tested across all modes, airflow is balanced, and you receive operation training and maintenance guidance.
It depends on your building type. Ductless mini-splits are ideal for Nassau County single-family estates, colonials, split-levels, Cape Cods, and waterfront properties that lack existing ductwork - they provide efficient heating and cooling without major construction. Homes with existing ductwork benefit from central air upgrades. We assess your space and recommend the best solution.
A single-zone ductless mini-split in Nassau County costs $4,000–$7,000 installed. Multi-zone systems (3–5 zones) range from $12,000–$25,000. Central air installation in a home with existing ductwork runs $8,000–$18,000. We provide detailed proposals after a load calculation and site assessment.
Yes. HVAC installations in Nassau County require DOB permits, and many buildings have additional requirements for condenser placement, line set routing, and noise compliance. Nassau County projects require town or village building permits rather than NYC DOB. Each municipality has its own process - we handle permitting in Garden City, Great Neck, Manhasset, and all Nassau County jurisdictions. We handle all permitting and coordination.
Yes - that's exactly what ductless mini-split systems are designed for. They require only a small hole in the wall for the refrigerant line set, making them perfect for Nassau County's single-family estates, colonials, split-levels, Cape Cods, and waterfront properties where adding traditional ductwork isn't feasible.
