Most residential AC installations take 4-8 hours, depending on the system type and complexity. Central air installations with existing ductwork typically finish in one day. Ductless systems often install faster since there’s no ductwork involved. Commercial installations or systems requiring new ductwork may take 1-2 days. We provide a realistic timeline during your estimate so you can plan accordingly. Weather and permit requirements can occasionally affect scheduling, but we communicate any changes immediately.
System sizing depends on your home’s square footage, insulation, window placement, and Long Island’s climate factors. An oversized system cycles on and off too frequently, wasting energy and failing to control humidity. An undersized system runs constantly without adequately cooling your space. Professional load calculations consider ceiling height, insulation quality, sun exposure, and local climate data. This ensures your new system runs efficiently and maintains consistent comfort throughout your South Hempstead home.
Most AC installations in South Hempstead require permits, especially for central air systems and commercial installations. Permit requirements ensure installations meet local building codes and safety standards. The permit process typically takes a few days and involves inspection of the completed work. Excellent Air Conditioning and Heating Service handles permit applications and coordinates inspections as part of our installation service. This protects you from potential code violations and ensures your installation meets all Nassau County requirements.
Yes, though older homes often present unique challenges like outdated electrical systems, lack of existing ductwork, or space constraints. Many older South Hempstead homes benefit from ductless mini-split systems that don’t require major renovations. If your home needs electrical upgrades to support a new AC system, we can coordinate with qualified electricians. We evaluate each situation individually and recommend solutions that work within your home’s existing structure and your budget.
Equipment warranties come directly from manufacturers and typically cover parts for 5-10 years, depending on the brand and model. Installation workmanship is warranted separately, covering any issues related to the installation process itself. This includes refrigerant line connections, electrical work, and system commissioning. If something goes wrong due to installation error, we return to fix it at no charge. Warranty terms are clearly explained before installation begins, so you understand exactly what’s covered.
Installation costs vary based on system type, home size, and installation complexity. Basic central air installations typically start around $3,000-$5,000 for smaller homes, while larger homes or high-efficiency systems cost more. Ductless systems range from $2,000-$4,000 per indoor unit. Commercial installations depend on building size and system requirements. We provide detailed written estimates that break down equipment and labor costs. No hidden fees or surprise charges – you know the total cost before work begins.
