AC Installation Process

Most residential AC installations take 6-8 hours for a straightforward replacement, or 1-2 days for new installations requiring ductwork or electrical upgrades. The timeline depends on your specific setup – replacing a central air system in a typical Freeport home with existing ductwork is usually completed in one day. However, if we need to install new ductwork, upgrade electrical panels, or work around unique architectural features common in older Long Island homes, the project may extend into a second day. We’ll give you an accurate timeline during our initial assessment so you can plan accordingly.
AC sizing depends on your home’s square footage, insulation, window placement, and Long Island’s specific climate conditions. An undersized unit will struggle during hot, humid summer days, while an oversized unit will cycle on and off too frequently, wasting energy and failing to properly dehumidify your home. We perform detailed load calculations that factor in your home’s unique characteristics, including ceiling height, insulation levels, and sun exposure. This ensures your new system provides consistent comfort while operating efficiently. Most Freeport homes need between 2-5 tons of cooling capacity, but proper sizing requires professional assessment rather than guesswork.
Central air works best if you already have ductwork in good condition and want to cool your entire home uniformly. Ductless systems are ideal for homes without existing ducts, room additions, or situations where you want independent temperature control in different areas. Many older Freeport homes benefit from ductless installation because adding ductwork can be expensive and disruptive. Ductless systems also offer higher energy efficiency and the flexibility to cool only occupied spaces. We’ll assess your home’s layout, existing infrastructure, and cooling priorities to recommend the best option for your specific situation and budget.
AC installation costs vary based on system type, home size, and complexity of the installation. Basic central air replacement typically ranges from $3,000-$7,000, while new installations requiring ductwork can cost $5,000-$12,000 or more. Ductless systems generally range from $2,000-$6,000 depending on the number of indoor units needed. Factors affecting cost include equipment efficiency ratings, electrical upgrades, permit requirements, and any modifications needed for your specific home. We provide detailed written estimates that break down all costs upfront, so you understand exactly what you’re paying for without hidden fees or surprises.
Yes, we handle all necessary permits for AC installation in Freeport and throughout Nassau County. Most AC installations require permits to ensure the work meets local building codes and safety standards. We’re familiar with Freeport’s specific requirements and have established relationships with local inspectors, which helps streamline the permitting process. The permit costs are included in our estimates, and we coordinate all inspections required for your installation. This protects you from potential issues when selling your home and ensures your installation meets all current safety and efficiency standards.
You receive manufacturer warranties on all equipment, typically ranging from 5-12 years depending on the brand and model you choose. Additionally, we provide warranties on our installation workmanship to ensure everything is installed correctly and functions properly. If any issues arise from our installation work, we’ll return to address them at no charge. We also help you register your equipment warranties and provide guidance on maintenance requirements to keep your warranties valid. Many manufacturers offer extended warranty options, and we can explain these choices to help you make the best decision for long-term protection of your investment.
