How long does central AC installation take in Uniondale homes?

Most central air installations take one to two days, depending on your home’s setup and whether new ductwork is needed. If you already have ductwork in place, we can typically complete the installation in a single day. Homes requiring new ductwork or electrical upgrades may need an additional day. We’ll give you an accurate timeline during our initial assessment so you can plan accordingly. Weather delays are rare since most of our work happens inside your home.
The right AC size depends on your home’s square footage, insulation quality, ceiling height, window placement, and local climate factors. We perform detailed load calculations rather than using rough estimates. An oversized unit cycles on and off too frequently, wasting energy and failing to remove humidity properly. An undersized unit runs constantly and never reaches comfortable temperatures. Our technicians measure and calculate the exact cooling capacity your Uniondale home needs for efficient, effective cooling.
Yes, we obtain all required permits for your central AC installation and ensure the work meets Nassau County, NY building codes. This includes electrical permits if new circuits are needed and mechanical permits for the HVAC system itself. We schedule required inspections and handle any follow-up items with local authorities. Having proper permits protects you if you sell your home and ensures your installation meets safety standards. The permit costs are included in our upfront pricing.
Absolutely. We install complete ductwork systems for homes that currently use window units, baseboard heating, or radiators. This technique involves running supply and return ducts through your basement, crawl space, or attic to reach all rooms. We design the duct layout to provide even cooling throughout your home while minimizing any impact on your living space. The process takes longer than a simple equipment replacement but gives you the comfort and efficiency benefits of central air conditioning.
Your new central air system comes with manufacturer equipment warranties that typically cover parts for 5-10 years, depending on the brand and model you choose. We also provide a guarantee on our installation workmanship, covering any issues related to our installation work. This includes refrigerant connections, electrical work, ductwork modifications, and system setup. We’ll return to address any installation-related problems at no charge. Extended warranty options are available if you want additional coverage beyond the standard manufacturer warranties.
Central AC installation costs vary based on your home’s size, the equipment you choose, and whether ductwork installation is needed. Basic installations for homes with existing ductwork typically start around $3,000-$5,000, while complete systems with new ductwork range higher. High-efficiency units cost more upfront but save money on monthly energy bills. We provide detailed written estimates that break down equipment, labor, permits, and any additional work needed. Financing options are available to help spread the investment over manageable monthly payments.
