Ductless vs. Central Air: Which Is Better for Your Home?

Choosing between ductless mini-split and central air conditioning systems is one of the most important decisions Vancouver homeowners face when upgrading their cooling systems. At Equinox HVAC, we've completed hundreds of AC installation Vancouver projects with both system types, giving us unique insights into which works best for different homes. This guide breaks down installation complexity, costs, efficiency, and real-world performance to help you make the right choice.

Understanding the Key Differences

Ductless mini-split systems use wall-mounted indoor units connected to an outdoor compressor via refrigerant lines. Each indoor unit operates independently, requiring only a three-inch hole through the wall for installation. These systems provide both heating and cooling, making them versatile year-round solutions for BC's climate.

Central air conditioning distributes cooled air through a network of ducts connected to a single outdoor condenser and indoor air handler. The system cools your entire home from one thermostat, delivering conditioned air through vents in each room. This traditional approach works best in homes with existing ductwork.

Installation Complexity and Timeline

Based on our HVAC installation Surrey and Vancouver projects, installation complexity differs dramatically between these systems.

Ductless Mini-Split Installation takes 1-2 days for most homes. Our technicians mount indoor units on walls or ceilings in desired rooms, drill a small conduit hole, and connect refrigerant lines to the outdoor compressor. There's minimal disruption to your home—no drywall removal, no attic work, and no structural modifications. We recently completed a three-zone installation in a 1,400 sq ft Kitsilano heritage home in one day, preserving the original architecture while adding modern cooling.

Central Air Installation requires 2-5 days if ducts exist, or several weeks if ductwork must be added. Installing new ducts involves cutting into walls and ceilings, running metal or flexible ductwork through attics and crawlspaces, and patching drywall afterward. Last year we installed central air in a 2,200 sq ft Surrey home with existing ducts in three days. However, a comparable Burnaby home without ducts required two weeks due to ductwork installation throughout three floors.

Cost Comparison: Initial Investment vs. Long-Term Savings

Ductless systems in Vancouver typically cost $7,000-$15,000 for multi-zone installations covering 2-4 rooms. Single-zone systems for additions or single rooms range from $3,000-$6,000. While the per-unit cost seems higher than central air, homes without existing ducts save $5,000-$10,000 by avoiding ductwork installation.

Central air systems cost $5,000-$12,000 when ducts already exist. However, adding ductwork increases total costs to $12,000-$22,000 or more. One recent home cooling Vancouver project for a 1,900 sq ft East Vancouver home required $8,500 for ductwork alone before installing the $6,500 central AC unit.

Operating Costs: Our clients switching from central air to ductless typically see 30-40% reductions in cooling costs. Ductless systems avoid the 25-40% energy loss inherent in ductwork from leaks and heat transfer. One Burnaby family reduced their summer cooling bills from $180 monthly to $110 after installing a four-zone ductless system in their 1,800 sq ft home.

Energy Efficiency: The Numbers That Matter

HVAC efficiency BC standards favor ductless systems significantly. Modern ductless units achieve SEER ratings of 20-30+, while typical central air systems reach 14-20 SEER. This translates to measurably lower energy consumption.

Ductless advantages: Inverter technology allows compressors to run continuously at variable speeds rather than cycling on and off, reducing energy waste. Each zone operates independently—you cool only occupied rooms rather than the entire house. Our measurements show a 1,600 sq ft Coquitlam home using a three-zone ductless system consumed 35% less electricity than comparable homes with central air during summer 2024.

Central air efficiency: Modern central systems with SEER ratings above 16 are vastly more efficient than older units. However, duct losses remain the fundamental limitation. Even perfectly sealed ducts lose 15-20% efficiency as air travels through unconditioned attics and crawlspaces. A recent energy efficient hvac vancouver audit we conducted found a five-year-old central system with 18 SEER rating performing at effective 13 SEER due to duct inefficiencies.

System Comparison at a Glance

Which System Fits Your Home?

Choose Ductless Mini-Split If You Have:

• Older homes without existing ductwork - Installing ducts in heritage homes often damages original features and costs $8,000-$15,000 alone

• Home additions or renovations - A detached garage conversion, basement suite, or sunroom addition gets independent climate control without extending ductwork

• Homes under 2,000 sq ft - Multi-zone systems efficiently cover smaller footprints with 2-4 indoor units

• Desire for zone control - Families with different temperature preferences benefit from individual room settings

• Limited installation timeframes - Tenants moving in next week or finishing renovations on deadline

Choose Central Air If You Have:

• Existing ductwork in good condition - Leveraging existing infrastructure keeps costs reasonable at $5,000-$12,000

• Homes over 2,000 sq ft - Larger homes benefit from centralized whole-home cooling with uniform temperatures

• Preference for hidden systems - All components hide behind walls except small vents

• Superior air filtration needs - Family members with severe allergies or asthma benefit from whole-home HEPA filtration and UV purification

• Plans for whole-home humidity control - Central systems integrate seamlessly with whole-home humidifiers and dehumidifiers

Real Equinox Case Studies

Case Study 1: 1928 Vancouver Craftsman Home - This 1,650 sq ft home had no existing ductwork and owners wanted to preserve original plaster walls and crown molding. We installed a four-zone ductless mini split vancouver system with units in the living room, kitchen, and two bedrooms. Total cost: $11,200. Installation took one day. The homeowners report $145 monthly summer savings compared to their old window units and improved winter heating efficiency.

Case Study 2: 2,400 sq ft Surrey Family Home - Built in 2015 with existing ductwork throughout, this home needed AC for Vancouver's increasingly warm summers. We installed a high-efficiency 18 SEER central air system for $8,900. The three-day installation integrated seamlessly with their gas furnace. Whole-home cooling maintains consistent 22°C throughout summer with monthly operating costs around $95.

Case Study 3: Burnaby Condo (850 sq ft) - This second-floor condo had electric baseboard heating and no cooling. We installed a single-zone ductless heat pump for $4,200, providing both summer cooling and efficient winter heating. Installation completed in four hours with zero disruption to neighbors. Annual energy savings exceeded $800 compared to baseboard heating alone.

Maintenance and Longevity

Ductless systems require monthly filter cleaning by homeowners (a five-minute task) and annual professional servicing. With proper maintenance, quality ductless units last 15-20 years. Our service records show Mitsubishi and Daikin units regularly operating efficiently after 12-15 years.

Central air needs filter changes every 1-3 months, annual professional tune-ups, and duct cleaning every 3-5 years. Properly maintained central systems last 15-20 years, though ductwork can deteriorate earlier in humid crawlspaces or unconditioned attics, requiring repairs or replacement.
