Our AC Installation Process

Straightforward Installation, Professional Results

First, we assess your space and cooling needs. This isn’t a quick glance – we measure square footage, evaluate insulation, check existing ductwork, and consider your home’s layout. Proper sizing matters because an oversized unit cycles on and off constantly, while an undersized unit runs constantly without reaching your target temperature.

Next, we handle the installation itself. We protect your floors and furniture, remove the old equipment safely, and install your new system according to manufacturer specifications. For central AC, that includes connecting refrigerant lines, testing electrical connections, and ensuring proper airflow through your ductwork.

Finally, we test everything thoroughly before we leave. We check refrigerant levels, verify electrical connections, test all safety controls, and walk you through your new system’s operation. You get documentation for warranty purposes and our contact information for any questions down the road.

Everything You Need for Reliable Cooling

Our air conditioning installation services cover residential and commercial properties throughout Searingtown. Whether you need central AC installation for your whole house, ductless mini-splits for specific zones, or commercial HVAC installation for your business, we handle projects of all sizes.

Most residential AC installations take 4-8 hours, depending on the system type and any modifications needed. Central air conditioning installation usually takes a full day, especially if we’re replacing ductwork or upgrading electrical service. Ductless mini-split installations are typically faster, often completed in 3-5 hours. Commercial installations vary widely based on system size and complexity. We’ll give you a realistic timeframe during our initial assessment so you can plan accordingly.
Proper AC sizing depends on your home’s square footage, insulation levels, window placement, and ceiling height. Most Searingtown homes need 1 ton of cooling capacity per 500-600 square feet, but Long Island’s humidity requires careful calculation. An oversized unit won’t remove humidity effectively and will cycle on and off frequently. An undersized unit runs constantly without reaching your target temperature. We perform detailed load calculations during our assessment to determine the right size for your specific home and cooling needs.
Yes, we handle all necessary permits for AC installation in Searingtown and throughout Nassau County. Most central air conditioning installations require permits to ensure electrical and refrigerant work meets local codes. We’re familiar with Nassau County’s permit requirements and inspection processes. The permit cost is typically included in our installation quote, and we schedule inspections as needed. This protects you from code violations and ensures your installation meets all safety requirements for insurance and warranty purposes.
Absolutely. Many older Searingtown homes don’t have central air ductwork, but you have several options. Ductless mini-split systems are perfect for homes without existing ducts – they provide efficient cooling without major renovations. We can also install new ductwork for central AC, though this involves more extensive work. High-velocity ductwork is another option that uses smaller ducts that fit in tight spaces. During our assessment, we’ll explain which approach works best for your home’s layout and your budget.
Our AC installation includes manufacturer warranty on the equipment (typically 5-10 years depending on the brand and model) plus our labor warranty on the installation work. We warranty our workmanship for one year, covering any issues related to installation quality. This includes refrigerant connections, electrical work, and system setup. Equipment warranties cover parts and sometimes labor for manufacturer defects. We provide all warranty documentation and handle warranty claims if issues arise. Proper installation is crucial for maintaining manufacturer warranty coverage.
AC installation costs vary based on system type, home size, and installation complexity. Central air conditioning installation typically ranges from $3,000-$8,000 including equipment and labor. Ductless mini-split installations usually cost $2,000-$5,000 depending on the number of zones. Additional costs may include electrical upgrades, ductwork modifications, or permits. We provide detailed written estimates that break down equipment and labor costs so you understand exactly what you’re paying for. Financing options are available for qualified customers to help manage the investment in your comfort.
