Professional AC installation that keeps you comfortable all summer without the surprise breakdowns or sky-high energy bills.
Your AC system runs efficiently from day one, keeping your space consistently comfortable without straining to keep up. You’re not dealing with frequent repairs or wondering if your system will make it through the next heat wave.
Energy bills stay predictable instead of spiking every summer month. The system operates quietly and reliably, doing its job without becoming a constant source of stress or unexpected expenses.
You get years of dependable cooling because the installation was done right the first time. No callbacks, no do-overs, no wondering if you should have chosen someone else.
Excellent Air Conditioning and Heating Service has been handling AC installations throughout Locust Valley and the surrounding Long Island area for years. We understand how the coastal humidity affects system performance and what it takes to keep homes and businesses comfortable.
We’re licensed, insured, and focused on installations that last. Our team knows local building codes, understands the mix of older and newer properties in the area, and sizes systems properly for Long Island’s climate demands.
You’re working with contractors who live and work in the community, not a crew that’s here today and gone tomorrow.
We start with an assessment of your space, existing ductwork, and cooling needs. No guessing at system size or rushing through measurements. We calculate the proper capacity for your specific situation.
You get a detailed estimate that covers equipment, installation, permits, and any additional work needed. Everything’s spelled out upfront so you know exactly what you’re paying for.
Installation day means protecting your property, installing your system according to manufacturer specifications, and testing everything before we consider the job complete. We clean up completely and walk you through your new system’s operation.
Your system comes with manufacturer warranties on equipment plus our guarantee on the installation work. You have our contact information for any questions or service needs going forward.
