Air Conditioning Installation & Replacement in Long Island

Upgrade to Reliable, Energy-Efficient Cooling

If your AC is struggling — or your home never had central air at all — upgrading to a modern cooling system can transform your comfort. Many Long Island homes rely on window units or aging central AC, leading to hot spots, high electric bills, and loud operation. A new system provides cool, even temperatures, lower humidity, and whisper-quiet performance throughout your home. From East Northport to Huntington, Smithtown, Commack, and beyond, our team delivers expert installation and reliable results.

What’s Included in Our AC Installation


Tailored AC System Design

We assess your home’s size, insulation, layout, and cooling habits to design the right system — no one-size-fits-all solutions. Proper sizing ensures consistent comfort and efficiency.


Central Air Conditioning Options

For homes with existing ductwork, we install high-efficiency central AC systems that deliver strong, even cooling. We can also design new duct systems if needed.


Ductless Mini-Split Solutions

No ducts? No problem. Ductless mini-splits provide zoned cooling without major construction. Great for older Long Island homes, additions, and multi-level layouts.


High-Efficiency Upgrades

We install AC units with modern SEER2 ratings and variable-speed compressors for better comfort and lower energy use. Many customers see substantial savings compared to older units.
