Calgary’s summer heat is no joke, when July hits 30°C and smoke rolls in from nearby wildfires, a reliable air conditioner becomes more than comfort, it’s peace of mind.Whether you’re building a new home in Livingston or upgrading an aging system in Altadore, the right AC ensures consistent cooling when Calgary weather is at its worst.
At Comfort Union, we’ve completed hundreds of local installs, 70% of them ductless in 2024 alone, especially in older homes across Inglewood, Crescent Heights, and Mount Pleasant, where retrofitting ductwork is tricky. Our firsthand insights help us recommend the best system for your home’s layout, age, and energy goals.
What’s the Average Cost to Install an Air Conditioner in Calgary?
In Calgary’s 2025 market, the average air conditioner installation cost ranges from $4,300 to $8,600, depending on system type, home layout, and brand.

Central Air Conditioning Systems typically cost $4,300–$8,600 fully installed. These are best for full-home cooling and work well in houses with existing ductwork. Expect monthly energy bills between $65–$90.
Ductless Mini-Split Systems start around $3,000 and can go up to $10,000, depending on the number of zones and complexity. They’re ideal for older Calgary homes in areas like Crescent Heights or Ramsay where ductwork is limited. These systems usually add $50–$100/month to your utility bill.
Additional Costs to Keep in Mind
- Permits & Ductwork Modifications: Older homes often require airflow upgrades or code-compliant duct repairs, which can add $500–$2,000.
Smart Thermostat Add-ons: For remote access and energy tracking, smart thermostats cost an extra $300–$600, depending on the brand.
At Comfort Union, we often see older Calgary homes with narrow mechanical spaces that require compact ductless systems or low-profile air handlers. so installation costs vary based on these real-world constraints.
What Factors Influence Air Conditioner Installation Costs in Calgary?
Several key factors determine how much you’ll pay to install an air conditioner in Calgary:
1. Home Size & Layout
The larger your home, the more powerful the AC unit you’ll need. A good rule of thumb is 1 ton of cooling capacity for every 600–700 square feet. For example, a 2,000 sq. ft. home typically needs a 3-ton unit.
2. Efficiency Rating (SEER2)
Higher Seasonal Energy Efficiency Ratio (SEER2) means better performance but a higher upfront cost.
- 14 SEER2: Basic efficiency (budget-friendly)
- 16–18 SEER2: Mid-tier efficiency (better savings)
- 20+ SEER2: Premium efficiency (highest savings, rebates eligible)
3. Ductwork Condition
Older or retrofit homes often require duct repairs or upgrades to ensure proper airflow, which can add $500–$2,000 to your total cost.
4. Brand & Model
Top-tier brands like Trane, Lennox, and Carrier generally come at a premium due to better performance, warranties, and longevity.
5. Installation Complexity
Multi-level homes, zoned systems, or difficult attic/basement access can increase labor time and costs.
How Much Does It Cost to Run an Air Conditioner Monthly in Calgary?
In 2025, electricity rates in Calgary range from $0.16 to $0.26 per kWh, depending on your utility provider and usage tier.
Here’s what that means for typical monthly AC operating costs:
- Central AC Systems use about 400–600 kWh per month, which translates to approximately $65–$90 on your electricity bill.
- Ductless/Mini-Split Systems consume slightly less—around 300–500 kWh per month, costing roughly $50–$100 monthly
Keep in mind, high-efficiency units (with higher SEER2 ratings) will lower your energy usage over time, especially during Calgary’s peak summer months.
Should You Choose Central AC or a Ductless System in Calgary?
When deciding between central air conditioning and a ductless mini-split system in Calgary, consider your home’s layout and cooling needs.
Central AC is ideal for whole-home cooling in houses that already have ductwork. It’s quieter, integrates with your furnace system, and typically takes 1–3 days to install. However, it requires existing ducts or retrofitting, which can increase installation costs.
Ductless systems are better for zoned cooling, additions, or homes without existing ductwork. Each indoor unit cools a specific area, making them flexible for retrofits or partial-home solutions. Installation is quicker, typically one day per zone, but indoor units may produce slightly more fan noise.
Both systems offer energy-efficient options, and your choice largely depends on your home’s structure and whether you want whole-home or targeted cooling.
