How long does central AC installation take in Plainview homes?

Most central AC installations take one to two days, depending on your home’s setup and whether ductwork modifications are needed. Straightforward replacements where existing ducts are in good condition typically finish in one day. New installations or jobs requiring significant ductwork changes may take two days. The timeline gets discussed during your initial assessment, so you know exactly what to expect. Weather and permit approval can occasionally affect scheduling, but you’ll get advance notice of any delays.
The right size depends on your home’s square footage, insulation, window placement, and several other factors. A proper load calculation determines the exact cooling capacity needed – usually measured in tons or BTUs. Most Plainview homes need between 2 to 5 tons of cooling capacity. Oversized units waste energy and don’t remove humidity properly. Undersized units run constantly and never quite keep up. That’s why professional sizing calculations matter more than guessing based on square footage alone.
Central AC installation typically ranges from $3,000 to $8,000, depending on system size, efficiency rating, and installation complexity. Basic installations with standard efficiency units cost less than high-efficiency systems or jobs requiring extensive ductwork. You’ll get a detailed written estimate that breaks down equipment costs, labor, permits, and any additional work needed. The estimate stays valid for 30 days, so you have time to make your decision without pressure or surprise price changes.
Yes, we handle all necessary permits as part of the installation process. Nassau County, NY requires permits for central AC installations, and the local building department needs to inspect the work. We take care of the permit application, approval process, and scheduling inspections – it’s all included in your installation service. You don’t need to visit town hall or deal with paperwork. The installation isn’t considered complete until all inspections pass and you receive final approval from the building department.
We remove and dispose of old equipment properly as part of the installation service. Refrigerant must be recovered according to EPA regulations – it can’t just be vented into the atmosphere. We disconnect the old indoor and outdoor units carefully to avoid damage to your home. Most components get recycled through authorized facilities. You don’t need to arrange disposal or worry about environmental compliance. We clean up the work area completely before the job is considered finished.
You get manufacturer warranties on all equipment – typically 5 to 10 years on major components like compressors and heat exchangers. Labor warranties cover the installation work itself, usually for one to two years. Warranty terms vary by manufacturer and system type, but we explain everything clearly before installation begins. We handle registration with manufacturers automatically to ensure warranty coverage starts immediately. Keep all warranty documentation in a safe place, and remember that regular maintenance helps keep warranties valid.
