What's Included in Every Installation

Every AC installation includes proper equipment sizing, professional installation of all components, electrical connections, refrigerant lines, and system testing. We handle permits when required and ensure all work meets local building codes.

For central air systems, we evaluate your existing ductwork and recommend modifications if needed for optimal airflow. Ductless installations include mounting indoor units, running refrigerant lines, and positioning outdoor condensers for maximum efficiency and minimal noise.

Commercial installations receive the same attention to detail, whether you need rooftop units, split systems, or complex multi-zone setups. We coordinate with your schedule to minimize business disruption and ensure your customers and employees stay comfortable.

Most residential AC installations take one to two days, depending on the system type and complexity. A straightforward central air replacement in a home with existing ductwork usually takes 6-8 hours. New installations requiring ductwork modifications or electrical upgrades may take 1-2 full days. Ductless systems are often completed in 4-6 hours since they don’t require extensive ductwork. We’ll give you a realistic timeline during your estimate so you can plan accordingly.
AC sizing depends on your home’s square footage, ceiling height, insulation quality, window placement, and local climate factors. In Nassau County’s humid climate, proper sizing is crucial – an oversized unit won’t remove humidity effectively, while an undersized unit will run constantly without cooling properly. We perform detailed load calculations during our assessment, measuring your space and evaluating factors like sun exposure and insulation. This ensures your new system provides optimal comfort and efficiency for Long Island’s summer conditions.
Most AC installations in Rockville Centre require permits, especially for new installations or significant system upgrades. The Village of Rockville Centre building department requires permits for electrical work, refrigerant line installations, and structural modifications. We handle permit applications and ensure all work meets local codes and manufacturer requirements. This protects you from potential issues during home sales or insurance claims, and ensures your installation is done safely and legally.
Absolutely. Many older Nassau County homes weren’t built with central air conditioning, but we have several options. Ductless mini-split systems are popular because they don’t require extensive ductwork – we mount indoor units in rooms that need cooling and connect them to an outdoor condenser. For homes where central air is preferred, we can install new ductwork, though this involves more extensive work. We’ll assess your home’s layout and discuss the best options for your specific situation and budget.
Central air uses ductwork to distribute cool air throughout your home from a single indoor unit, while ductless systems use individual indoor units in each room connected to an outdoor condenser. Central air provides whole-home cooling through existing or new ductwork, making it ideal for homes with good duct systems. Ductless installation is less invasive – we mount wall or ceiling units and run refrigerant lines through small holes. Ductless systems offer zone control, letting you cool specific areas as needed, which can be more energy-efficient for some homes.
AC installation costs vary based on system type, home size, and installation complexity. Central air systems typically range from $3,000-$8,000 including equipment and installation, while ductless systems range from $2,500-$6,000 depending on the number of zones. Factors affecting cost include equipment efficiency ratings, necessary electrical upgrades, ductwork modifications, and permit fees. We provide detailed written estimates that break down all costs upfront, so you understand exactly what you’re paying for before any work begins.
