What Proper Installation Actually Gets You

Your new AC system runs efficiently from day one. No short cycling that wastes energy. No hot spots in bedrooms or uneven cooling that leaves you adjusting the thermostat constantly.

You get lower monthly bills because the system is sized correctly for your space. Not oversized where it cycles on and off too frequently. Not undersized where it runs constantly trying to keep up.

The installation meets manufacturer specs, which means your warranty stays intact. You’re not dealing with service calls six months later because corners were cut during setup. Your system lasts longer, runs quieter, and gives you the comfort you paid for.

Here's How We Handle Your Installation

We start with an assessment of your space, existing ductwork, and electrical setup. This determines the right system size and identifies any prep work needed before installation day.

On installation day, we protect your floors and furniture, then remove your old system if needed. We install the new equipment according to manufacturer specifications, test all connections, and verify proper refrigerant levels and airflow.

Before we leave, we walk you through your new system’s operation and maintenance requirements. You get all warranty information and our contact details for any questions that come up later.

What's Included in Your Installation

Your installation includes proper equipment sizing based on your home’s square footage, insulation, and layout. We handle electrical connections, refrigerant lines, and ductwork modifications if needed.

We install both indoor and outdoor units, connect your thermostat, and test the complete system under load. All debris and old equipment get removed from your property.

You receive manufacturer warranties on equipment plus our workmanship guarantee. We also provide operating instructions and maintenance recommendations to keep your system running efficiently for years.

How long does AC installation take in Uniondale homes?

Most residential AC installations take 6-8 hours for a complete system replacement. This includes removing your old equipment, installing the new indoor and outdoor units, connecting refrigerant lines, and testing everything. If we need to modify ductwork or upgrade electrical service, it might take longer. We’ll give you a realistic timeline during your estimate so you can plan accordingly. Straightforward replacements where we’re swapping similar equipment usually go faster than installations requiring significant modifications.

What size AC system do I need for my Uniondale home?

System sizing depends on your home’s square footage, insulation levels, window placement, and ceiling height. A typical 1,500 square foot home needs a 2.5-3 ton system, but that’s just a starting point. We perform load calculations that factor in your specific conditions rather than guessing based on square footage alone. Oversized systems waste energy and don’t control humidity well. Undersized systems run constantly and never reach comfortable temperatures. Proper sizing is critical for efficiency and comfort.

Do you handle permits for AC installation in Uniondale?

Yes, we handle all permit requirements for your AC installation. Nassau County requires permits for most HVAC work, and we know the local codes and inspection requirements. We pull the necessary permits, schedule inspections, and ensure everything meets current building standards. This protects you from compliance issues and ensures your installation is done correctly. Some homeowners try to skip permits, but that can cause problems with insurance claims or when selling your home later.

Can you install ductless AC systems in older Uniondale homes?

Ductless systems work great in older homes without existing ductwork or where adding ducts isn’t practical. We can install single-zone units for specific rooms or multi-zone systems that cool your entire home. Installation is less disruptive than central air since we don’t need to run ductwork through walls. We just need to connect indoor and outdoor units with refrigerant lines through a small hole in your exterior wall. Many of Uniondale’s older homes benefit from ductless systems because they provide efficient cooling without major renovations.

What brands of AC equipment do you install?

We install major brands like Carrier, Trane, Lennox, and Rheem that offer solid warranties and local service support. We don’t push one brand over others – we recommend equipment based on your budget, efficiency goals, and specific needs. Higher-end units offer better energy efficiency and quieter operation, while standard models provide reliable cooling at lower upfront costs. We’ll explain the differences during your estimate so you can make an informed decision that fits your situation and budget.

How much does AC installation cost in Uniondale?

Installation costs vary based on system size, equipment quality, and complexity of the job. Basic central air installations typically start around $4,000-$6,000, while high-efficiency systems or complex installations can cost more. Ductless systems range from $3,000-$8,000 depending on how many zones you need. We provide written estimates that break down equipment and labor costs so you know exactly what you’re paying for. Financing options are available if you prefer to spread payments over time rather than paying upfront.
