Every Type of Installation We Handle

We install central air conditioning systems for whole-home cooling, ductless mini-splits for specific zones or additions, and commercial units for Franklin Square businesses. Each installation includes proper equipment sizing, electrical connections, refrigerant line installation, and system testing.

For older Franklin Square homes, we often work with existing ductwork or recommend ductless solutions when traditional central air isn’t practical. We handle the electrical permits and inspections required in Nassau County, so you don’t need to navigate that process yourself.

Every installation comes with manufacturer warranty coverage and our guarantee on the installation work. We also provide maintenance recommendations to keep your new system running efficiently for years, not just the first season.

Most residential AC installations take 4-8 hours depending on the system type and your home’s setup. Central air systems with existing ductwork typically finish in one day. Ductless mini-split installations often complete in 3-4 hours since there’s no ductwork involved. If we need to run new electrical lines or modify ductwork significantly, the job might extend to a second day. We’ll give you a realistic timeline during our initial assessment so you can plan accordingly.
AC sizing depends on your home’s square footage, insulation, window placement, and ceiling height. Many Franklin Square homes need 2-4 ton units, but the only way to know for sure is through proper load calculation. Oversized units cycle on and off too frequently, creating humidity problems and higher bills. Undersized units run constantly and never cool properly. We measure your space and calculate the exact cooling load rather than guessing based on square footage alone.
Yes, ductless mini-splits work great in Franklin Square’s older homes, especially when adding central air isn’t practical or cost-effective. These systems don’t require ductwork, so installation is less invasive and usually faster. You can cool specific rooms or zones without affecting the whole house. Many of our Franklin Square customers choose ductless for home additions, converted basements, or when their existing ductwork is in poor condition. The outdoor unit connects to indoor units through small refrigerant lines that run through the wall.
Nassau County requires electrical permits for most AC installations, especially when we’re running new electrical lines or installing units that require 240V connections. We handle the permit applications and inspections as part of our service, so you don’t need to deal with the county directly. The permit process typically adds 1-2 days to project timeline but ensures your installation meets local codes. Some simple replacement installations on existing electrical connections may not require permits, which we’ll determine during our initial assessment.
Installation costs vary based on system type, home size, and complexity of the job. Central air systems typically range from $3,000-$8,000 including equipment and installation. Ductless mini-splits usually cost $2,000-$5,000 depending on how many indoor units you need. Additional costs come from electrical work, ductwork modifications, or permits. We provide upfront pricing after assessing your specific situation, so you’ll know the total cost before we start any work. No surprises or hidden fees.
All equipment comes with manufacturer warranties, typically 5-10 years on parts and 1-2 years on the compressor. We also warranty our installation work for one year, covering any issues related to our workmanship like refrigerant leaks, electrical connections, or mounting problems. If something goes wrong with how we installed your system, we’ll fix it at no charge. Equipment failures due to manufacturing defects get handled through the manufacturer warranty process, but we coordinate those repairs for you.
