Most residential AC installations take 6-8 hours for a complete central air system, or 4-6 hours for ductless systems. Older Hewlett homes sometimes require additional electrical work or ductwork modifications, which can extend the timeline to 1-2 days. We’ll give you an accurate timeframe during your free consultation based on your specific situation. Complex installations involving new ductwork or electrical panel upgrades are scheduled accordingly, and we always communicate any timeline changes upfront.
AC sizing depends on your home’s square footage, insulation, window placement, ceiling height, and local climate factors. Many Long Island homes have oversized units that waste energy and don’t control humidity properly. We perform Manual J load calculations to determine the right size – typically 20-25 BTUs per square foot for well-insulated homes, but this varies significantly. Proper sizing is crucial because an oversized unit cycles on and off too frequently, while an undersized unit runs constantly without reaching comfortable temperatures.
Yes, we install both central air conditioning systems and ductless mini-split systems. Central air works well when you have existing ductwork or want whole-house cooling from one system. Ductless systems are perfect for home additions, rooms without ductwork, or when you want individual temperature control in different areas. Many Hewlett homeowners choose ductless for flexibility and energy efficiency. We’ll recommend the best option based on your home’s layout, existing infrastructure, and cooling preferences during your consultation.
Nassau County requires permits for most AC installations, especially when electrical work or refrigerant lines are involved. We handle all permit applications and schedule required inspections as part of our installation service. The permit process typically takes 3-5 business days, which we factor into your installation timeline. Some simple equipment replacements using existing connections may not require permits, but we always verify requirements with local codes. Having proper permits protects you and ensures the work meets safety standards and manufacturer warranty requirements.
AC installation costs vary based on system type, size, and complexity of the installation. Central air systems typically range from $3,500-$8,000 including installation, while ductless systems run $2,500-$6,000 depending on the number of zones. Factors affecting price include electrical upgrades, ductwork modifications, equipment efficiency ratings, and manufacturer selection. We provide detailed written estimates during your free consultation, breaking down equipment and labor costs with no hidden fees. Financing options are available for qualified customers to spread costs over manageable monthly payments.
You receive manufacturer warranties on all equipment – typically 5-10 years on parts and 1-2 years on the compressor, depending on the brand and model selected. We also provide a labor warranty on our installation work, covering any issues related to the installation process. Manufacturer warranties require professional installation and regular maintenance to remain valid. We register your equipment warranty and provide all documentation. Extended warranty options are available for additional coverage. Our ongoing service relationship means we’re here to handle any warranty claims or maintenance needs throughout your system’s life.
