Seasonal Energy Efficiency Ratio (SEER): A Guide to Choosing an Energy-Efficient HVAC System
Are you considering installing a highly energy-efficient heating and cooling system (HVAC)? The Seasonal Energy Efficiency Ratio (SEER), or TRÉS in French, is a key factor to consider.
What is SEER?
SEER measures the energy efficiency of an air conditioning system or the cooling function of a heat pump. A higher SEER means the unit is more efficient and uses less energy to produce the same amount of cooling. For more info, visit our last article :

What SEER is Considered Highly Efficient?
Since the 1990s, standards have significantly evolved. A HVAC system with a SEER of 8 to 9 was common back then. With the 2005 U.S. Energy Policy Act, the minimum required SEER was raised to 13. Today, a SEER of 13 to 14 is considered average, while high-end systems can reach values up to 20 or 21, offering exceptional performance for residential and commercial applications.
Does a Higher SEER Mean a More Expensive HVAC System?
Generally, yes, but several advantages should be considered:
- Enhanced Performance: A high-efficiency system offers better performance and quieter operation.
- Long-Term Energy Savings: A high-performance system reduces your energy bills while maintaining optimal comfort.
- Reduced Repair Costs: Increased reliability can lower long-term repair expenses.
- Subsidies and Tax Incentives: Certified systems, like Energy Star, may qualify for subsidies and tax credits.
Can the SEER of an Existing HVAC System Change?
No, but energy efficiency decreases over time, making replacement with a higher SEER model more relevant. Staying informed about SEER developments helps you make an informed decision when purchasing your next system.
Can a SEER of 13 be Effective?
Yes, depending on the situation. For a small house or commercial property in a temperate climate, a SEER of 13 can be sufficient.
Is it Possible to Increase the SEER of an Existing Unit?
Yes, by replacing certain components, you can increase the SEER. For example, going from a SEER of 14 to 16 by adding a third-party horizontal coil and a variable-speed condenser. However, consider the following:
- Component Compatibility: Upgrades may not always be compatible.
- Project Cost: Sometimes, investing in a new unit is more sensible.
- Warranty: Modifying a system may void the existing warranty.
Conclusion
SEER is crucial when choosing an HVAC system. A higher SEER means better energy efficiency, long-term savings, and increased comfort. Consider your needs, climate, and budget to choose the ideal unit. By researching and choosing wisely, you can find a
high-efficiency HVAC system that meets your needs while reducing your environmental impact.
