Here's How We Handle Installation

First, we come out and look at your house. We measure spaces, check existing ductwork, and figure out what size system you actually need. Not what some chart says, but what works for your specific home.

Next, we give you a written estimate that breaks down equipment and labor costs. No hidden fees or surprise charges later. You know exactly what you’re paying for.

Installation day, we show up on time with everything we need. We protect your floors and furniture, install your new system, test everything thoroughly, and clean up completely. You get a walkthrough of your new system and all your warranty information before we leave.

How long does central AC installation take in my home?

Most central air installations take one to two days, depending on your home’s setup. If you already have ductwork in good condition, we can often complete installation in a single day. Homes that need new ductwork or electrical upgrades will take longer. We’ll give you an accurate timeline during your estimate so you can plan accordingly. We work efficiently but never rush the important details that ensure your system works properly for years.
System size depends on your home’s square footage, insulation, window placement, and ceiling height. A system that’s too small won’t cool effectively. Too large, and it cycles on and off constantly, wasting energy and wearing out faster. We do proper load calculations during our estimate, measuring your actual space and considering factors like sun exposure and insulation levels. This ensures you get a system that cools efficiently without oversizing.
Yes, we install ductwork as part of central AC installation. Many Seaford homes were built before central air was standard, so we’re experienced with adding ductwork to older houses. We route ducts through basements, attics, or crawl spaces depending on your home’s layout. The process takes longer than installations with existing ducts, but we minimize disruption to your daily routine and repair any walls or ceilings we need to access.
Installation costs vary based on system size, efficiency rating, and whether you need new ductwork. Basic installations for homes with existing ducts typically start around $3,000-$5,000. Homes requiring new ductwork or electrical upgrades cost more. High-efficiency systems have higher upfront costs but lower operating expenses. We provide detailed written estimates that break down equipment and labor costs so you understand exactly what you’re paying for.
Yes, we obtain all necessary permits and schedule required inspections with Seaford building departments. HVAC installations need permits to ensure safety and code compliance. We’re familiar with local requirements and handle the paperwork so you don’t have to deal with municipal offices. Permit costs are included in our estimates, and we coordinate inspection scheduling to avoid delays in getting your system up and running.
New systems need regular filter changes every 1-3 months depending on usage and filter type. Annual professional maintenance includes cleaning coils, checking refrigerant levels, and inspecting electrical connections. Most manufacturers require annual service to maintain warranty coverage. We offer maintenance plans that handle scheduled service and give you priority scheduling for repairs. Proper maintenance keeps your system running efficiently and extends its lifespan significantly.
