Package Units (often referred to as rooftop units) are an ideal, all-in-one solution for commercial properties, large residential buildings, and homes with limited indoor utility space on Long Island, NY. These systems house all heating and cooling components in a single outdoor cabinet, making them powerful, discreet, and easy to service.

Why Choose a Packaged HVAC Unit?

• All-in-One Efficiency: Combines your cooling and heating (AC/Furnace or Heat Pump) into one streamlined, tested unit for optimal performance.
• Ideal for Commercial Spaces: The perfect solution for Long Island commercial HVAC needs, including retail, office buildings, and restaurants.
• Easy Access & Maintenance: Being a single, outdoor unit (often rooftop), maintenance and Package Unit repair are simplified, minimizing disruption to your indoor operations.

Enhanced Security: Keeping the main unit outdoors reduces noise inside and protects valuable equipment from damage or vandalism.

Are you looking to cool an older home without existing ductwork, a garage conversion, or a home addition? Ductless Mini-Split systems are the flexible, energy-efficient cooling solution. These innovative units allow you to create customizable temperature zones, eliminating the energy waste of cooling unoccupied rooms.

The Ductless Advantage:

• Zone-Specific Comfort: Control the temperature in individual rooms independently—perfect for families with different comfort preferences.
• Unmatched Efficiency: Since there is no ductwork, the typical 20-30% energy loss from ducts is eliminated, resulting in significantly lower utility bills.
• Ideal for Long Island Homes: They are the perfect solution for historic homes, co-ops, or any residence where installing traditional ductwork is impractical or too costly.
• Year-Round Use: Our Ductless Mini-Split Installation services include advanced heat pump models, providing highly efficient heating in the winter and powerful cooling in the summer.

The finest air conditioning system is only as good as the Ductwork that carries the air. Poorly designed, damaged, or leaky ducts can waste up to 30% of your HVAC energy, leading to high bills and inconsistent cooling.

Long Island Heating and Cooling INC. specializes in comprehensive Air Duct Services to ensure your system operates flawlessly.

• Custom Ductwork Design: We engineer and install new duct systems for new construction or major remodels, prioritizing optimal airflow and system efficiency.
• Duct Sealing & Repair: We use advanced techniques to locate and seal leaks in existing ductwork, immediately boosting your system’s efficiency and cooling power.
• Ductwork Modifications: Adjusting or expanding existing ducts for new additions or renovated spaces to maintain balanced airflow throughout your Long Island property.

Improved Indoor Air Quality (IAQ): Properly sealed and clean ductwork prevents dust, allergens, and pollutants from entering your air stream, leading to a healthier indoor environment.
