What Proper Installation Really Gets You

Your new air conditioner isn’t just about staying cool. It’s about knowing your system will fire up every time you need it, without the stress of wondering if today’s the day it quits on you.

When we install your AC system correctly, you get consistent temperatures in every room. No more hot spots upstairs or that one bedroom that never quite cools down. Your energy bills drop because the system isn’t working overtime to compensate for poor installation.

You sleep better knowing your equipment is sized right for your home and installed by licensed professionals who understand Long Island’s unique climate challenges. The humidity stays controlled, the air quality improves, and you stop thinking about your AC system because it just works.

How We Handle Your Installation

First, we come out to assess your home and current setup. We measure your space, check your electrical system, and evaluate your existing ductwork. No guessing, no assumptions – just the facts we need to size your system correctly.

Next, we provide a clear, written estimate that breaks down equipment costs, labor, and any additional work needed. You’ll know exactly what you’re paying for before we start. No surprise charges or “unforeseen complications” that magically appear halfway through the job.

On installation day, our crew arrives on time with all the equipment and materials needed. We protect your floors and furniture, install your system according to manufacturer specifications, and test everything thoroughly before we leave. You get a walkthrough of your new system and all warranty information in writing.

Central and Ductless AC Systems

What's Included in Every Installation

Every AC installation includes proper load calculations to ensure your system is sized correctly for your home. We don’t just swap out equipment – we make sure your new system can actually handle your cooling needs efficiently.

You get professional ductwork evaluation and modifications if needed. Many Lattingtown homes have ductwork that’s been patched and modified over the years. We identify problem areas and fix them so your new system performs as designed.

All installations include electrical connections by licensed technicians, refrigerant line installation, system commissioning, and complete testing. We register your equipment warranty, provide operating instructions, and schedule your first maintenance visit to keep everything running smoothly.

How long does AC installation typically take in my home?

Most residential AC installations in Lattingtown take one to two days, depending on your specific situation. A straightforward replacement where we’re swapping out an existing system usually takes 6-8 hours. If we need to modify ductwork, upgrade electrical connections, or install new refrigerant lines, it might extend to a second day. We’ll give you an accurate timeline during our initial assessment so you can plan accordingly. We always aim to have your system up and running by the end of each work day, so you’re never left without cooling overnight.

What size AC unit do I need for my house?

The right size depends on your home’s square footage, insulation, window placement, ceiling height, and several other factors specific to your property. Many contractors just use square footage, but that often leads to oversized systems that cycle on and off too frequently, wasting energy and failing to control humidity properly. We perform detailed load calculations that account for your home’s unique characteristics and Long Island’s climate. This ensures your system runs efficiently and keeps you comfortable without the short cycling problems that plague improperly sized units.

Should I choose central air or ductless mini-split systems?

It depends on your home’s layout and existing infrastructure. Central air makes sense if you already have ductwork in good condition and want whole-house cooling from a single system. Ductless mini-splits work well for homes without existing ducts, room additions, or situations where you want different temperature zones. Many Lattingtown homeowners choose ductless for second floors or converted spaces where extending ductwork would be difficult or expensive. We’ll evaluate your specific situation and explain the pros and cons of each option based on your home’s needs and your comfort preferences.

How much does AC installation cost in Lattingtown?

Installation costs vary based on system type, size, and complexity of the job. A basic central air replacement typically ranges from $4,000 to $8,000, while high-efficiency systems or complex installations can run higher. Ductless systems vary depending on how many indoor units you need. The key is getting an accurate assessment of what your home actually requires – not just a generic quote. We provide detailed written estimates that break down equipment, labor, and any additional work needed, so you understand exactly what you’re paying for before we start.

What warranty coverage comes with my new AC system?

You get manufacturer warranty coverage on all equipment – typically 5-10 years on parts depending on the brand and model you choose. Our installation work is backed by our service guarantee, and we register your equipment warranty to ensure you’re fully covered. We also provide written documentation of all warranty terms and help you understand what’s covered and for how long. Many manufacturers offer extended warranty options for additional peace of mind. We’ll explain all available coverage options during your consultation so you can make an informed decision about protecting your investment.

Do you handle permits and inspections for AC installation?

Yes, we handle all necessary permits and coordinate required inspections as part of our installation service. Nassau County has specific requirements for HVAC installations, and we’re familiar with local codes and inspection processes. We pull permits before starting work and schedule inspections at the appropriate stages of installation. This ensures your installation meets all local requirements and protects you from potential issues down the road. You don’t need to worry about navigating the permit process or dealing with inspectors – we handle all of that as part of providing complete professional service.
