AC Installation Process

Here's How We Handle Your Installation

First, we assess your home’s cooling needs. This means looking at square footage, insulation, windows, and existing ductwork. We’re not trying to sell you the biggest unit we have – we’re figuring out what actually works for your space.

Next, we provide a clear estimate with no hidden fees. You’ll know exactly what equipment we’re installing, what the labor costs, and what’s covered under warranty. No surprises, no upselling during the job.

Installation day, our team arrives on time with all necessary equipment and permits. We protect your floors and furniture, install your new system properly, test everything thoroughly, and clean up completely. Before we leave, we walk you through your new system and answer any questions you have.

What's Included in Your Installation

Your AC installation includes proper equipment sizing, professional installation of indoor and outdoor units, electrical connections, refrigerant lines, and ductwork modifications if needed. We handle all permits and inspections required by Nassau County.

We install central air systems, ductless mini-splits, and high-efficiency units from trusted manufacturers. Each installation comes with manufacturer warranties on equipment plus our warranty on labor. We also provide a complete system walkthrough so you understand how to operate and maintain your new AC.

Whether you’re replacing an old system or installing AC for the first time, we make sure everything is done to code and built to last. That means proper electrical work, secure mounting, correct refrigerant levels, and thorough testing before we consider the job complete.

Most residential AC installations take one full day, typically 6-8 hours depending on your home’s setup. If we’re installing ductwork or upgrading electrical panels, it might take two days. We’ll give you an accurate timeline during your estimate so you can plan accordingly. We always aim to complete installations efficiently without rushing the quality of work that keeps your system running properly for years.
AC size depends on your home’s square footage, insulation quality, window placement, ceiling height, and local climate factors. A unit that’s too small won’t cool effectively, while an oversized unit cycles on and off too frequently, wasting energy and creating humidity problems. We perform detailed load calculations to determine the right capacity for your specific home, ensuring optimal comfort and efficiency rather than just guessing based on square footage alone.
Yes, we obtain all necessary permits and schedule required inspections for your AC installation. Nassau County requires permits for most HVAC installations, and we’re familiar with local building codes and requirements. This protects you from potential issues when selling your home or filing insurance claims. We handle the paperwork and coordinate with inspectors so you don’t have to deal with the bureaucratic process yourself.
Central AC uses existing ductwork to distribute cool air throughout your home from one indoor unit, while ductless systems use individual units in each room or zone. Central systems work well if you already have ducts, but ductless gives you more control over individual room temperatures and can be more efficient. Ductless is also ideal for home additions or older homes without existing ductwork. We’ll recommend the best option based on your home’s layout and your comfort preferences.
AC installation costs vary based on equipment type, home size, and installation complexity. Basic central AC systems typically start around $3,000-$5,000 installed, while high-efficiency or ductless systems can range higher. We provide detailed written estimates that break down equipment and labor costs so you know exactly what you’re paying for. Remember that proper installation is crucial – cheaper installations often lead to expensive problems down the road.
All equipment comes with manufacturer warranties that typically cover parts for 5-10 years depending on the brand and model. We also provide our own labor warranty on the installation work itself. This means if something goes wrong due to installation issues, we’ll fix it at no charge. We stand behind our work because proper installation is what makes the difference between an AC system that lasts and one that gives you problems from day one.
