What Is SEER and Why It Matters
SEER, or Seasonal Energy Efficiency Ratio, measures how efficiently an air conditioner cools a home over a season. Higher SEER ratings indicate greater efficiency, which can lower energy bills, reduce wear on your system, and contribute to longer equipment life.

Understanding SEER Ranges
Choosing the right SEER rating depends on your home size, energy goals, and Calgary climate. Below is a quick reference table:
SEER Rating | Typical AC Efficiency | Ideal Use in Calgary |
13–14 SEER | Standard efficiency | Older homes or limited budget |
15–16 SEER | Improved efficiency | Most Calgary homes with moderate cooling needs |
17–20 SEER | High efficiency | Larger homes, long-term energy savings focus |
21+ SEER | Ultra-high efficiency | Premium systems, extreme focus on efficiency |
Higher SEER units cost more upfront but provide better energy savings over the life of the system.
SEER vs Upfront and Long-Term Costs
Air conditioners with higher SEER ratings usually have higher installation costs. However, they can lower monthly electricity bills and reduce the frequency of repairs due to modern, durable components.

Repair and Maintenance Considerations for High SEER AC Units
Higher SEER systems may have more complex components, such as variable-speed compressors or advanced coil designs. While these features improve efficiency, they can increase maintenance requirements.
Common Considerations
- Regular maintenance: Annual inspections prevent efficiency losses and ensure warranty compliance.
- Component sensitivity: High-efficiency parts can be more expensive to replace.
- Professional service: Certified technicians, like those at Comfort Union, ensure proper maintenance and repairs.
SEER Ratings and Real-World Comfort
Real-world comfort depends on more than SEER alone. Proper sizing, ductwork efficiency, and thermostat placement play critical roles in keeping your Calgary home evenly cooled.
Key Factors
- Proper sizing: Oversized units cycle too frequently, reducing efficiency.
- Ductwork efficiency: Leaks or poor design can negate SEER advantages.
- Thermostat placement: Accurate temperature readings help maintain consistent comfort.

Choosing the Right SEER for Your Calgary Home
Selecting the best SEER rating requires balancing upfront costs, energy savings, and comfort needs. Most Calgary homes benefit from 15–18 SEER units, but premium installations may justify 20+ SEER systems.

Frequently Asked Questions
What is the minimum SEER rating in Alberta?
Alberta law requires new central air conditioners to have a minimum SEER of 13. Installing lower-rated units is not allowed, ensuring homes meet basic energy-efficiency standards and reduce electricity costs.
What is the $5,000 rule for AC?
The $5,000 rule suggests that if a new AC installation costs less than $5,000, upgrading to a higher SEER may not be cost-effective. For Calgary homes, consider energy savings versus upfront costs before choosing a premium system.
What is considered a good SEER rating?
For most Calgary homes, a SEER rating of 15–18 offers a strong balance between energy savings, comfort, and installation cost. Units above 18 SEER are high-efficiency but more expensive upfront.
Is it worth upgrading from 14 SEER to 16 SEER?
Upgrading from 14 to 16 SEER can reduce electricity bills by 10–15% and improve comfort. It’s typically worth it in Calgary if you plan to keep the AC for 10+ years and want long-term savings.
