AC Installation Process

Here's How We Handle Your Installation

First, we assess your space and cooling needs. This means measuring rooms, checking existing ductwork, and understanding your budget. We’re not pushing the most expensive option – we’re finding what actually works for your situation.

Next, we provide a clear estimate with no hidden fees. You’ll know exactly what equipment we’re installing, what the labor includes, and when we can get it done. If permits are needed, we handle that process.

Installation day, our team arrives on time with all necessary equipment. We protect your floors, install your system according to manufacturer specifications, and test everything before we leave. You get a walkthrough of your new system and all warranty information. Clean-up is included – we don’t leave you with a mess to deal with.

What's Included in Every Installation

Every AC installation includes proper system sizing, professional installation following manufacturer specifications, and thorough testing of all components. We handle electrical connections, refrigerant lines, condensate drainage, and thermostat setup.

For central air systems, we inspect and modify ductwork as needed. Ductless installations include mounting indoor and outdoor units with proper refrigerant line routing. Commercial jobs get the same attention to detail with consideration for business hours and minimal disruption.

You receive warranty information for both equipment and our installation work. We also provide basic operation instructions and maintenance recommendations to keep your system running efficiently. Emergency replacement service is available when your current system fails unexpectedly.

Most residential AC installations take 6-8 hours for a complete central air system, including ductwork modifications. Ductless systems are usually faster – often 4-6 hours depending on the number of indoor units. If we’re replacing an existing system with similar equipment, it’s typically on the shorter end. New installations in homes without existing ductwork take longer, sometimes requiring two days. We’ll give you a realistic timeline during the estimate so you can plan accordingly.
AC sizing depends on your home’s square footage, insulation, window placement, and ceiling height. A typical 1,500 square foot Lynbrook home needs about 2.5-3 tons of cooling capacity, but that’s just a starting point. We do a proper load calculation that considers your specific situation, including factors like which direction your home faces and how much shade you have. Oversized units waste energy and don’t remove humidity properly. Undersized units run constantly and never cool adequately. Getting the size right is crucial for comfort and efficiency.
Yes, most AC installations in Lynbrook require permits, especially for new installations or major replacements involving electrical or ductwork changes. We handle the permit application process as part of our service – you don’t need to deal with the paperwork or village office visits. The permit ensures the installation meets local building codes and safety requirements. It also protects you if you sell your home later, as buyers and inspectors will see the work was done legally and properly inspected.
Central air installation typically ranges from $3,500-$7,000 depending on system size, efficiency rating, and ductwork requirements. Ductless systems start around $2,500 for single-zone units, with multi-zone systems running $4,000-$8,000. Factors affecting cost include equipment brand, energy efficiency ratings, installation complexity, and any electrical upgrades needed. We provide detailed written estimates so you know exactly what you’re paying for. Emergency replacements may cost more due to after-hours labor, but we’re upfront about any additional charges.
Central air uses ductwork to distribute cool air throughout your home from one indoor unit, while ductless systems use individual indoor units in each room or zone. Central air provides more even temperatures and is often preferred for whole-home cooling, but requires existing ductwork or space to install it. Ductless systems are more energy-efficient for cooling specific areas, install faster, and work well in homes without existing ducts. They also allow different temperature settings in different rooms. The best choice depends on your home’s layout, existing infrastructure, and cooling preferences.
Installation day starts with our team arriving on time with all equipment and materials. We’ll protect your floors and furniture, then begin with any electrical or ductwork modifications needed. The outdoor unit gets positioned and connected, followed by indoor components and refrigerant lines. We test all connections, charge the system with refrigerant, and run it through complete operational cycles. Before leaving, we walk you through basic operation, show you how to change filters, and provide all warranty documentation. The process is typically completed in one day for most residential installations.
