Professional AC installation that keeps your home comfortable all summer without the headaches or surprise costs.
Your home stays consistently cool without those frustrating hot spots in certain rooms. You’re not dealing with a system that breaks down every summer or energy bills that make you cringe when they arrive.
A properly installed AC system runs efficiently for years, not months. You get even cooling throughout your house, lower monthly utility costs, and the peace of mind that comes with knowing it was done right the first time.
When we install your system, you’re investing in comfort you can count on. No more sweating through Long Island summers or wondering if your AC will make it through the next heat wave.
Excellent Air Conditioning and Heating Service has been handling AC installations across Long Island for years. We know the local climate challenges and what systems work best in East Williston homes.
Our technicians are licensed, insured, and trained on the latest installation techniques. We handle everything from permits to final testing, so you don’t have to worry about code compliance or warranty issues.
We’re not the cheapest option, and that’s intentional. You’re getting installation work that lasts, equipment that performs, and service you can actually reach when you need it.
First, we assess your home’s cooling needs and existing ductwork. This isn’t a quick glance – we measure square footage, check insulation, and evaluate your electrical system to ensure proper sizing.
Next, we provide a detailed estimate with equipment options and installation timeline. No surprises, no hidden fees, just clear pricing for the work ahead.
On installation day, our team arrives with all necessary equipment and permits. We remove your old system if needed, install the new unit with proper refrigerant lines and electrical connections, and test everything thoroughly before we leave. You get a walkthrough of your new system and all warranty information before we consider the job complete.
