Our AC Installation Process

Here's How We Handle Installation

First, we calculate your home’s actual cooling load. This determines the right size system for your space, not just what fits or what’s cheapest. Oversized units waste energy and create humidity problems. Undersized units run constantly and wear out fast.

Next, we handle the installation itself. This includes proper refrigerant line installation, electrical connections, ductwork modifications if needed, and system commissioning. We test everything before we leave to make sure it’s working correctly.

Finally, we walk you through your new system’s operation and maintenance requirements. You get all warranty information, operating manuals, and our contact information for any future service needs.

What's Included in Installation

Every AC installation includes load calculation, equipment sizing, professional installation, system commissioning, and cleanup. We handle central air conditioning systems, ductless mini-splits, and commercial HVAC installations throughout Lake Success and Nassau County.

You also get permit handling, code compliance verification, and manufacturer warranty registration. Our technicians protect your home during installation and leave the work area clean when finished.

Whether you’re replacing an old system, installing AC in a new addition, or upgrading to a more efficient unit, we handle the technical details so you don’t have to worry about them.

How long does AC installation take in Lake Success homes?

Most residential AC installations take one to two days, depending on the complexity of your home’s layout and whether ductwork modifications are needed. Simple replacements where we’re swapping out similar equipment often finish in one day. New installations or systems requiring significant ductwork changes may take two days. We’ll give you an accurate timeline during your estimate so you can plan accordingly. Weather and permit requirements can occasionally extend timelines, but we communicate any delays immediately.

What size AC unit do I need for my home?

The right size depends on your home’s square footage, insulation, window placement, ceiling height, and local climate conditions. We perform a Manual J load calculation to determine exact requirements rather than guessing based on square footage alone. Oversized units cycle on and off frequently, wasting energy and failing to remove humidity properly. Undersized units run constantly and struggle to maintain comfortable temperatures. Our technicians measure and calculate to get the sizing right the first time.

Do you handle permits for AC installation in Nassau County?

Yes, we handle all permit requirements for HVAC installations in Lake Success and throughout Nassau County. This includes pulling the necessary permits, scheduling inspections, and ensuring all work meets local building codes. Permit requirements vary depending on the type of installation and your home’s existing systems. We factor permit costs into your estimate upfront so there are no surprises. Having proper permits protects you if you sell your home and ensures the work meets safety standards.

What's the difference between central AC and ductless installation?

Central AC installation connects to your existing ductwork to cool your entire home through one system. Ductless mini-split installation involves mounting indoor units in specific rooms and connecting them to an outdoor condenser. Central systems work well when you have good existing ductwork and want whole-home cooling. Ductless systems are ideal for homes without ducts, room additions, or when you want zone control. We evaluate your home’s layout and your cooling needs to recommend the best option for your situation.

How much does professional AC installation cost in Lake Success?

Installation costs vary based on system type, home size, ductwork requirements, and equipment efficiency levels. Basic central AC replacement typically ranges from $3,000 to $7,000 including installation. High-efficiency systems or complex installations cost more upfront but often save money long-term through lower energy bills. 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.

What warranty coverage comes with new AC installation?

New AC equipment comes with manufacturer warranties covering parts for 5-12 years depending on the brand and model. We also provide labor warranties on our installation work, typically one to two years. Manufacturer warranties require proper installation and regular maintenance to remain valid, which is why professional installation matters. We register your equipment warranty and provide all documentation you need. Extended warranty options are available through most manufacturers if you want additional coverage beyond the standard terms.
