Split vs. Central vs. Ductless: Which AC System Delivers Superior Value for Calgary Homes?

Strategic System Selection for Calgary’s Unique Climate

Selecting the optimal AC system type for your Calgary home requires balancing multiple factors: your home’s structure, budget considerations, comfort requirements, and our unique climate patterns. At Purcell Heating and Air, we assess these variables to identify which system architecture—central, split, or ductless—will deliver maximum value for your specific situation.


Central Air Conditioning Systems

Ideal Home Profile: Single-family homes with existing ductwork, open floor plans, whole-home cooling needs

Advantages for Calgary Homes

  • Whole-home cooling from a single system

  • Hidden components maintain aesthetic appeal

  • Consistent temperature throughout the home

  • Single point of maintenance

  • Excellent integration with air purification

  • Typical lifespan of 15-20 years with proper maintenance

Limitations for Calgary Homes

  • Requires existing ductwork or significant installation investment

  • Less zoning flexibility without additional equipment

  • Energy losses through ductwork (up to 30% in poorly sealed systems)

  • Higher initial investment ($7,000-$15,000 installed)

  • All-or-nothing operation less ideal for our variable climate

Value Equation

  • Cost per square foot cooled: $3.50-$7.50

  • Energy efficiency: Moderate to high (depends on duct quality)

  • Installation complexity: Moderate (higher if adding ductwork)

  • Return on investment timeline: 7-10 years


Split Air Conditioning Systems

Ideal Home Profile: Most Calgary single-family homes, especially those with existing forced-air heating systems

Advantages for Calgary Homes

  • Excellent performance in our dry climate

  • Lower installation costs when utilizing existing ductwork

  • Good whole-home humidity control

  • Variable-speed options work well with Calgary’s temperature swings

  • Good integration with existing furnace blowers

  • Typical lifespan of 15-18 years

Limitations for Calgary Homes

  • Still requires ductwork throughout the home

  • Limited zoning capabilities without additional equipment

  • Outdoor unit can be affected by extreme weather

  • Less ideal for homes with space constraints

  • Installation costs of $6,000-$12,000

Value Equation

  • Cost per square foot cooled: $3.00-$6.00

  • Energy efficiency: Moderate to high

  • Installation complexity: Moderate

  • Return on investment timeline: 6-9 years


Ductless (Mini-Split) Air Conditioning Systems

Ideal Home Profile: Older Calgary homes without ductwork, additions, finished basements, homes needing zoned cooling

Advantages for Calgary Homes

  • No ductwork required—ideal for older Calgary homes

  • Zoned cooling reduces energy waste

  • Precise temperature control per room

  • Excellent for supplemental cooling in problem areas

  • Lower installation disruption

  • Higher efficiency in variable climate conditions

  • Typical lifespan of 15-20 years

Limitations for Calgary Homes

  • Indoor air handlers visible in each cooled room

  • Multiple points of maintenance

  • Higher cost per square foot for whole-home applications

  • Limited air filtration compared to central systems

  • Installation costs of $3,000-$5,000 per zone

Value Equation

  • Cost per square foot cooled: $4.00-$8.00 (whole home), $10-$20 (single zone)

  • Energy efficiency: Very high

  • Installation complexity: Low to moderate

  • Return on investment timeline: 5-8 years


Hybrid/Dual Fuel Systems

Ideal Home Profile: Energy-conscious Calgary homeowners wanting year-round climate control

Advantages for Calgary Homes

  • Year-round operation (heating and cooling)

  • Lower operational costs through fuel switching

  • Excellent for our variable climate conditions

  • Reduced carbon footprint

  • Potential for significant rebates and incentives

  • Typical lifespan of 15-20 years

Limitations for Calgary Homes

  • Higher initial investment ($10,000-$18,000 installed)

  • More complex installation and maintenance

  • Requires both gas and sufficient electrical service

  • Not necessary for homes with efficient furnaces

Value Equation

  • Cost per square foot conditioned: $5.00-$9.00

  • Energy efficiency: Very high

  • Installation complexity: High

  • Return on investment timeline: 8-12 years


Decision Framework: Assessing Your Specific Needs

Existing Infrastructure Assessment

  • Quality and extent of existing ductwork

  • Electrical service capacity

  • Space availability for indoor and outdoor units

Cooling Load Requirements

  • Whole home vs. targeted cooling

  • Occupancy patterns and schedules

  • Problem areas (hot spots, sun exposure)

Budget Considerations

  • Initial investment capacity

  • Operating cost sensitivity

  • Expected length of home ownership

Future-Proofing Factors

  • Potential home additions

  • Changing usage patterns

  • Energy cost projections

  • Climate change considerations
