AC Installation Process Overview

Here's How Your Installation Actually Works

First, our technician evaluates your space to determine the right system size and type for your home. This isn’t guesswork – we calculate cooling loads based on square footage, insulation, windows, and local climate conditions.

Next, we handle all permits and scheduling with your utility company if needed. On installation day, our team arrives with all equipment and materials. We protect your floors and furniture, then remove old equipment if you’re replacing an existing system.

The new system goes in with careful attention to proper refrigerant lines, electrical connections, and ductwork. Everything gets tested thoroughly before we clean up and walk you through operation and maintenance basics. You get warranty information and contact details for future service needs.

Most residential AC installations take one to two days, depending on the system type and any ductwork modifications needed. Straightforward replacements of existing central air systems typically finish in one day. New installations requiring extensive ductwork or electrical upgrades may take two days. We provide a realistic timeline during the initial assessment and keep you informed if anything changes during the work.
System size depends on your home’s square footage, insulation levels, window types, ceiling height, and local climate conditions. A professional load calculation determines the exact capacity needed – usually measured in tons or BTUs. Oversized systems waste energy and don’t control humidity well. Undersized systems run constantly and never achieve comfortable temperatures. We perform this calculation during the initial consultation to ensure proper sizing.
Yes, Excellent Air Conditioning and Heating Service handles all necessary permits for AC installation in Hewlett Bay Park and throughout Nassau County. This includes building permits for new installations and electrical permits when significant electrical work is required. We know local code requirements and inspection schedules. Permit costs are discussed upfront so there are no surprises in your final bill.
Ductless AC systems work particularly well in older Hewlett Bay Park homes where adding traditional ductwork would be difficult or expensive. These systems require only small holes for refrigerant lines and electrical connections. They’re ideal for room additions, homes with radiator heating, or spaces where window units currently provide cooling. Installation is typically faster and less invasive than central air systems.
Central air installation connects to existing ductwork or requires new ducts throughout your home. The outdoor unit connects to an indoor air handler that distributes cooled air through vents. Ductless installation places individual units in specific rooms, connected to an outdoor compressor by refrigerant lines. Central air cools the whole house uniformly, while ductless systems allow zone control and are easier to install in homes without existing ductwork.
AC installation costs vary based on system type, home size, and installation complexity. Central air systems typically range from $3,000 to $8,000 including equipment and installation. Ductless systems range from $2,000 to $6,000 depending on the number of zones. High-efficiency equipment costs more upfront but reduces energy bills long-term. We provide detailed written estimates after evaluating your specific installation requirements and discussing equipment options.
