On installation day, our crew arrives on time with all the equipment and materials.

Everything You Need for Professional Installation

Our air conditioner installation includes proper system sizing, all necessary permits, professional installation, and thorough testing. We handle central AC systems, ductless mini-splits, and both residential and light commercial applications.

Every installation comes with manufacturer warranties on equipment and our guarantee on workmanship. We use quality equipment from trusted brands and install everything to code the first time.

You’ll also get a complete walkthrough of your new system, including how to operate it efficiently and when to schedule maintenance. We’re here for questions and service long after the installation is complete.

Most residential AC installations take 6-8 hours for a straightforward replacement, or 1-2 days for new installations that require ductwork modifications. The timeline depends on your specific situation – replacing an existing system in the same location is faster than installing a completely new system. We’ll give you an accurate timeframe during our initial assessment. Complex installations involving electrical upgrades or significant ductwork changes may take longer, but we’ll discuss all of this upfront so you know what to expect.
The right size depends on your home’s square footage, insulation levels, window types, ceiling height, and local climate conditions. We perform detailed load calculations rather than using rough estimates or rules of thumb. An oversized unit will cycle on and off frequently, wasting energy and failing to dehumidify properly. An undersized unit will run constantly and struggle to keep you comfortable. Our assessment takes about 30 minutes and ensures you get a system that’s properly matched to your home’s specific cooling needs.
Yes, we pull all necessary permits and handle inspections as part of our installation service. Nassau County requires permits for most HVAC installations, and we’re familiar with all local requirements and codes. This protects you from potential issues when you sell your home or file insurance claims. We schedule inspections at the appropriate times and make sure everything passes the first time. You don’t need to worry about dealing with the building department – we handle all of that paperwork and coordination.
We install quality equipment from several trusted manufacturers, including units appropriate for different budgets and efficiency requirements. Rather than pushing one brand, we recommend systems based on your specific needs, home characteristics, and budget. All the equipment we install comes with manufacturer warranties, and we only work with brands that have reliable local parts availability and service support. During our consultation, we’ll explain the differences between options and help you choose the system that makes the most sense for your situation.
Installation costs vary based on system size, equipment type, installation complexity, and any additional work needed like electrical upgrades or ductwork modifications. A basic replacement might start around $3,000-$5,000, while new installations or high-efficiency systems can cost significantly more. We provide detailed written estimates that break down all costs so you understand exactly what you’re paying for. There are no hidden fees or surprise charges – the estimate we give you is the price you pay.
You get manufacturer warranties on all equipment – typically 5-10 years on parts and sometimes longer on major components like compressors. We also guarantee our installation workmanship and will return to address any issues related to our work at no charge. This covers things like refrigerant leaks at connection points, electrical problems, or other installation-related issues. Equipment failures are handled through manufacturer warranty, but we coordinate that service for you. We stand behind our work because our reputation in this community depends on your satisfaction.
