What Proper Installation Really Means

Your AC system is only as good as the installation behind it. When we install your new air conditioner, you get consistent cooling in every room, not just the ones closest to the unit.

You get lower energy bills because properly sized and installed systems don’t work overtime trying to cool your home. The equipment lasts longer, breaks down less often, and keeps you comfortable during those brutal Long Island heat waves.

Most importantly, you get peace of mind. No wondering if it’ll work when you need it most. No surprise repair bills because corners were cut during installation. Just reliable cooling that works the way it’s supposed to.

Here's How We Handle Installation

First, we assess your home’s cooling needs and existing infrastructure. We measure square footage, check ductwork, and evaluate electrical capacity. This ensures we recommend the right size system for your space.

Next, we provide a detailed estimate covering equipment, installation, and any necessary upgrades. No surprises or hidden costs. Once you approve, we schedule the installation at your convenience.

On installation day, we protect your home with drop cloths and shoe covers. We remove your old system safely, install the new equipment, test everything thoroughly, and walk you through operation and maintenance. The whole process typically takes one day for most residential installations.

What's Included in Your Installation

Every AC installation includes proper equipment sizing, professional installation of indoor and outdoor units, refrigerant line connections, and electrical hookups. We handle ductwork modifications if needed and ensure proper drainage.

We install central air systems, ductless mini-splits, and commercial HVAC units. Each installation comes with manufacturer warranties on equipment plus our guarantee on workmanship. We also take care of permit applications and schedule required inspections.

For Plainview homes, we often recommend high-efficiency systems that handle our humid climate well. We’ll explain your options clearly so you can choose what makes sense for your home and budget.

Most residential AC installations take 6-8 hours to complete. Simple replacements where existing ductwork and electrical are adequate can be done in one day. More complex installations requiring ductwork modifications or electrical upgrades may take 1-2 days. We’ll give you a realistic timeline during our initial assessment so you can plan accordingly. Weather and equipment availability can occasionally affect scheduling, but we always communicate any changes promptly.
AC sizing depends on your home’s square footage, insulation, window placement, and ceiling height. A system that’s too small won’t cool effectively. One that’s too large cycles on and off frequently, wasting energy and failing to remove humidity properly. We perform detailed load calculations using industry-standard methods to determine the right capacity for your specific home. This ensures optimal comfort and efficiency while avoiding the problems that come with incorrect sizing.
Yes, we handle all permit applications and inspections required by Nassau County and local Plainview codes. Most AC installations require permits to ensure safety and code compliance. We’re familiar with local requirements and have established relationships with inspectors, which helps move the process along smoothly. The permit cost is included in our estimate, and we schedule all required inspections. You don’t need to deal with any of the paperwork or coordinate with building departments.
Absolutely. Ductless mini-split systems are excellent for older homes without existing ductwork or homes where adding ducts would be impractical. They’re also great for additions, converted garages, or rooms that don’t cool well with your current system. Installation is less invasive than central air since we only need to run refrigerant lines and electrical connections through small holes in the wall. Each indoor unit can be controlled independently, giving you precise temperature control in different areas of your home.
We handle complete removal and proper disposal of your old equipment. This includes safely recovering refrigerant according to EPA regulations, disconnecting electrical and refrigerant lines, and removing both indoor and outdoor units. We dispose of everything at appropriate recycling facilities. The removal process is included in your installation cost, so you don’t need to worry about hauling away heavy equipment or finding disposal sites that accept HVAC components.
Yes, all our installation work comes with a comprehensive warranty covering workmanship and labor. Equipment warranties are provided directly by manufacturers and typically range from 5-12 years depending on the brand and model you choose. We also provide ongoing service and maintenance to keep your system running efficiently. If any issues arise related to our installation work, we’ll return to make it right at no charge. We stand behind our work because proper installation is crucial for long-term system performance.
