Central AC vs. Ductless: Which Is Right for Your Home?

Central air conditioning distributes cooled air through your home's duct system from a single outdoor compressor and indoor air handler. It's the most common choice for homes that already have ductwork and need whole-home cooling.

Ductless mini-split systems connect an outdoor unit to one or more wall-mounted indoor heads — no ducts required. They're ideal for older homes, additions, garages, and any space where running new ductwork is impractical. Our network contractors install both.

What's Included in Your AC Installation

  • Site assessment and Manual J load calculation
  • Outdoor condenser unit installation and line-set connection
  • Indoor air handler or evaporator coil installation
  • Electrical disconnect and refrigerant charge
  • Permit application and inspection coordination
  • System test, commissioning, and homeowner walk-through

AC Installation Cost

A central AC replacement typically costs $3,500–$8,000, depending on system size, SEER rating, and your region. New installations with ductwork run $6,000–$15,000. Many utilities offer rebates of $300–$1,000 on high-efficiency (16+ SEER) units. Submit a free quote request for an estimate specific to your home and location.

FAQ

AC Installation FAQ

What size AC unit do I need for my home?
AC size is measured in tons (12,000 BTU per ton). A rough rule is 1 ton per 400–600 sq ft, but the right size depends on ceiling height, insulation, window area, and local climate. Your contractor will perform a Manual J load calculation to size the unit correctly — oversizing is a common and costly mistake.
What is the difference between a central AC and a ductless mini-split?
Central AC uses existing ductwork to cool the whole house from one outdoor unit. A ductless mini-split has an outdoor compressor connected to one or more indoor air handlers mounted on walls — no ductwork needed. Mini-splits work well for additions, garages, or homes without ducts.
How long does AC installation take?
A standard central AC replacement typically takes one day. A new installation that includes ductwork takes 2–5 days. Your contractor will give you a timeline after the site assessment.
Do I need a permit for AC installation?
Yes, most jurisdictions require a permit for new AC installation or replacement. Our network contractors handle the permit application and schedule the inspection.
How much does central AC installation cost?
Central AC installation typically costs $3,500–$8,000 for a standard replacement, depending on unit size, SEER rating, and local labor rates. New installations that include ductwork run $6,000–$15,000. Submit a free quote request for an estimate specific to your home.
What SEER rating should I look for?
SEER (Seasonal Energy Efficiency Ratio) measures cooling efficiency. The federal minimum is 14 SEER in most regions. High-efficiency units (18–26 SEER) cost more upfront but reduce energy bills significantly. Many utilities offer rebates on units 16 SEER and above.
