How long does AC installation typically take in Hewlett Neck homes?

Most residential AC installations take one to two days, depending on your home’s setup and the type of system. Straightforward central air replacements with existing ductwork usually finish in one day. New installations requiring electrical upgrades or ductwork modifications may take two days. We’ll give you an accurate timeline during our initial assessment, and we work efficiently to minimize disruption to your routine.

What size AC system do I need for my home?

System size depends on your home’s square footage, insulation, window placement, and ceiling height. We perform detailed load calculations during our assessment to determine the right capacity. Oversized systems waste energy and don’t control humidity well. Undersized systems struggle to cool your home effectively. Our technicians use industry-standard calculations to ensure proper sizing for optimal performance and efficiency.

Do you handle permits and inspections for AC installation?

Yes, we obtain all necessary permits and coordinate required inspections with Nassau County. This ensures your installation meets local building codes and safety requirements. Proper permits protect you if you sell your home and ensure warranty coverage remains valid. We handle the paperwork and scheduling so you don’t have to deal with municipal requirements.

What's the difference between central air and ductless systems?

Central air uses existing ductwork to distribute cool air throughout your home from one main unit. Ductless systems use individual indoor units in each room or zone, connected to an outdoor compressor. Central air works well for homes with existing ducts, while ductless is ideal for additions, older homes without ducts, or when you want zone control. We’ll recommend the best option based on your home’s layout and your cooling preferences.

How much does AC installation cost in Hewlett Neck?

Installation costs vary based on system type, size, and complexity of the job. Basic central air replacement typically ranges from $3,000 to $7,000, while new installations with ductwork can cost $5,000 to $12,000. Ductless systems range from $2,000 to $8,000 depending on the number of zones. We provide detailed written estimates with no hidden fees, so you know exactly what you’re paying before work begins.

What maintenance does a new AC system need?

New systems need regular filter changes every 1-3 months and annual professional maintenance. This includes cleaning coils, checking refrigerant levels, inspecting electrical connections, and testing system performance. Proper maintenance extends equipment life, maintains efficiency, and prevents unexpected breakdowns. We offer maintenance plans to keep your new system running smoothly and protect your warranty coverage.
