The real benefit? Peace of mind. You won’t be calling for repairs every few months because shortcuts were taken during installation. Your system will run reliably for years, backed by warranties that actually mean something when you need them.

Our AC Installation Process

Here's Exactly What Happens During Installation

First, we assess your home’s cooling needs. This isn’t just measuring square footage. We look at insulation, windows, ceiling height, and sun exposure to determine the right system size. Getting this wrong is the biggest mistake we see from other contractors.

Next, we handle the actual installation. This includes setting up the outdoor unit, connecting refrigerant lines, installing or modifying ductwork, and setting up the indoor components. We test everything multiple times to ensure proper operation.

Finally, we walk you through your new system. You’ll know how to operate it efficiently, when to change filters, and what to watch for. We also handle all permits and inspections so you don’t have to deal with the paperwork. Your system is ready to keep you cool from day one.

Most residential AC installations take one to two days, depending on your home’s setup and the type of system. Central air installations typically take longer than ductless systems because of the ductwork involved. We’ll give you a realistic timeline during our initial assessment. Factors like electrical upgrades, permit approvals, or complex ductwork can extend the timeline, but we’ll communicate any changes upfront. We work efficiently while ensuring every detail is handled properly because rushing leads to problems down the road.
AC sizing depends on much more than square footage. We calculate your home’s cooling load based on insulation levels, window types, ceiling height, sun exposure, and local climate conditions. An oversized unit will cycle on and off frequently, wasting energy and failing to remove humidity properly. An undersized unit will run constantly and never reach your desired temperature. Our technicians perform detailed load calculations to determine the exact capacity your home needs for optimal comfort and efficiency.
Yes, we handle all permit applications and inspections required for your AC installation. Nassau County and local municipalities have specific requirements for HVAC installations, including electrical connections and refrigerant handling. We’re familiar with local codes and inspection processes, so you don’t have to navigate the paperwork yourself. Proper permits protect you legally and ensure your installation meets safety standards. We won’t start work until all required permits are approved, and we schedule inspections as needed throughout the process.
Absolutely. We install both central air systems with new ductwork and ductless mini-split systems that don’t require ducts at all. For homes without existing ductwork, ductless systems are often the most practical solution. They provide efficient cooling with minimal disruption to your home’s structure. If you prefer central air, we can design and install ductwork, though this involves more extensive work. We’ll assess your home’s layout and discuss the pros and cons of each option so you can make an informed decision.
Our installations come with manufacturer warranties on equipment and our own labor warranty on installation work. Equipment warranties typically cover parts for 5-10 years depending on the brand and model. Our labor warranty covers any issues related to installation workmanship. This means if a problem develops because of how we installed your system, we’ll fix it at no charge. We also provide detailed warranty documentation and help you register your equipment with the manufacturer to ensure full coverage protection.
AC installation costs vary based on system type, home size, and installation complexity. Central air systems typically cost more than ductless units, and homes requiring new ductwork or electrical upgrades will have higher costs. We provide detailed written estimates that break down equipment and labor costs with no hidden fees. During our assessment, we’ll discuss different system options and their costs so you can choose what fits your budget and cooling needs. We believe in transparent pricing so you know exactly what you’re paying for.
