Professional AC installation done right the first time, so you stay comfortable all summer long.
You want an air conditioner that works when you need it most. Not one that breaks down during the first heat wave or drives your electric bill through the roof.
When your AC installation is done right, you get consistent temperatures in every room. Your energy bills stay predictable. And you don’t spend your weekends calling repair companies.
That’s what proper installation looks like. The right equipment, sized correctly for your home, installed by technicians who know what they’re doing. No shortcuts, no guesswork, no surprises three months later when something goes wrong.
Excellent Air Conditioning and Heating Service has been handling AC installations in Manhasset and throughout Nassau County for years. We understand how Long Island’s climate affects your cooling needs and what it takes to keep homes comfortable during humid summers.
Our technicians are licensed, insured, and trained on the latest equipment. We’ve worked on everything from older colonial homes to new construction, so we know how to handle the unique challenges each property presents.
You’re not getting a fly-by-night operation or someone learning on your dime. You’re getting experienced professionals who do this work every day.
First, we assess your home’s cooling needs. This means looking at square footage, insulation, windows, and existing ductwork. We’re not trying to sell you the biggest unit we have – we’re figuring out what actually works for your space.
Next, we provide a clear estimate with no hidden fees. You’ll know exactly what equipment we’re installing, what the labor costs, and what’s covered under warranty. No surprises, no upselling during the job.
Installation day, our team arrives on time with all necessary equipment and permits. We protect your floors and furniture, install your new system properly, test everything thoroughly, and clean up completely. Before we leave, we walk you through your new system and answer any questions you have.
