Professional AC installation that works the first time, every time, with no surprises or callbacks.
Your AC system stops being something you think about. No more sweating through hot nights or cranking up fans that barely help. No more utility bills that make you cringe when they arrive.
A properly installed air conditioner runs efficiently, cools evenly, and lasts years longer than rushed installations. You get consistent temperatures in every room, lower energy costs, and the confidence that comes from knowing your system was installed right.
When summer heat hits Long Island, you’ll have reliable cooling that keeps your family comfortable and your energy bills reasonable. That’s what professional AC installation delivers.
Excellent Air Conditioning and Heating Service has been installing AC systems throughout Carle Place and Nassau County for years. We understand how Long Island’s humidity affects cooling needs and which systems work best in local homes.
Licensed, insured, and familiar with local building codes, our team handles everything from permit applications to final inspections. We’ve worked in homes built in the 1950s and brand-new construction, so we know what works and what doesn’t.
Being local means faster response times, ongoing support, and technicians who understand the specific challenges of cooling homes in this area.
First, our technician evaluates your space, existing ductwork, and electrical setup. We calculate the right system size based on square footage, insulation, and local climate factors. You get a detailed estimate that covers equipment, labor, permits, and cleanup.
Installation day starts with protecting your floors and furniture. Old equipment gets removed safely, and new components are installed according to manufacturer specifications. All electrical connections are tested, refrigerant lines are pressure-tested, and the system runs through complete startup procedures.
Before leaving, our technician walks you through system operation, maintenance schedules, and warranty details. You get documentation for permits, warranties, and service records. The job isn’t finished until your new AC is cooling properly and you understand how everything works.
