What's Included in Professional Installation

Every AC installation includes proper system sizing, electrical connections, refrigerant lines, and ductwork modifications if needed. We handle both central air systems and ductless mini-split installations for homes and commercial properties throughout South Farmingdale.

How long does AC installation typically take?

Most residential AC installations take 6-8 hours for a straightforward replacement, or up to a full day for new installations requiring electrical or ductwork modifications. The timeline depends on your home’s specific setup, the type of system being installed, and whether permits and inspections are required. Commercial installations typically take longer due to system complexity and size. During your initial consultation, you’ll get a realistic timeframe based on your specific project so you can plan accordingly.

Do I need permits for AC installation in South Farmingdale?

Yes, most AC installations in South Farmingdale require permits, especially for new electrical connections or refrigerant work. The good news is that we handle all permit applications and coordinate required inspections as part of our service. This ensures your installation meets local building codes and protects you from potential issues when selling your home. Attempting to skip permits might save money upfront, but it can create expensive problems later during home inspections or insurance claims.

What size AC system do I need for my home?

AC system sizing depends on your home’s square footage, insulation quality, window placement, ceiling height, and local climate factors. A system that’s too small won’t cool effectively, while an oversized system cycles on and off too frequently, wasting energy and failing to control humidity properly. We perform load calculations using industry standards to determine the right capacity for your specific home. This isn’t guesswork – it’s engineering that ensures optimal comfort and efficiency for your investment.

Should I choose central air or a ductless system?

Central air makes sense if you already have ductwork in good condition and want whole-home cooling from a single system. Ductless mini-splits work better for homes without existing ducts, room additions, or situations where you want individual temperature control in different areas. Ductless systems are also more efficient for cooling specific zones rather than the entire house. The best choice depends on your home’s layout, existing infrastructure, and how you actually use your living space.

How much does AC installation cost in South Farmingdale?

AC installation costs vary based on system type, home size, existing infrastructure, and equipment quality. Basic central air replacement might run $3,000-$6,000, while new installations requiring ductwork or electrical upgrades cost more. Ductless systems range from $2,000-$5,000 depending on the number of zones. High-efficiency equipment costs more upfront but saves money long-term through lower energy bills. We provide written estimates after evaluating your specific situation, so you know exactly what you’re paying before any work begins.

What maintenance does a new AC system need?

New AC systems need regular filter changes every 1-3 months depending on usage and filter type. Annual professional maintenance includes cleaning coils, checking refrigerant levels, inspecting electrical connections, and testing system performance. This preventive care extends equipment life, maintains efficiency, and catches small problems before they become expensive repairs. We offer maintenance plans that include priority service and discounts on repairs. Proper maintenance is essential for keeping your warranty valid and ensuring reliable operation throughout the system’s lifespan.
