Understanding SEER Ratings in Ottawa: How Efficiency Impacts Your Comfort and Costs

What are SEER and EER?

When shopping for a new air conditioner or heat pump, you’ll often see ratings like SEER and EER. Here’s what they mean:

SEER (Seasonal Energy Efficiency Ratio): Measures the cooling output of your AC system over a typical cooling season, divided by the total energy consumed. It reflects overall seasonal efficiency.
EER (Energy Efficiency Ratio): Focuses on performance at a specific outdoor temperature (usually 35°C), showing how efficient a unit is under peak conditions.

Both ratings indicate how much cooling you get per unit of energy—higher numbers mean greater efficiency.

How Ratings Affect Your Bills

The higher the SEER rating, the less energy your system will use to cool your home. As Cross Heating notes, “higher SEER uses less energy.”

That said, savings don’t scale evenly. Moving from SEER 10 to SEER 14 may save a lot, but going from SEER 18 to SEER 20 offers smaller incremental benefits.

Still, over the long run, even modest efficiency gains can add up on Ottawa’s summer electricity bills.

New Standards and Regulations

Canada has recently increased efficiency requirements for new cooling equipment, meaning today’s systems are significantly more efficient than those sold just a decade ago.

SEER minimum thresholds are rising, ensuring that Ottawa homeowners upgrading their systems automatically benefit from better technology and lower operating costs.

Choosing High-Efficiency Units

When replacing an AC or heat pump, look for ENERGY STAR® certified or higher-SEER models.

While they may cost more upfront, they typically pay back through reduced energy use.

ENERGY STAR estimates that replacing an older system with a high-efficiency unit can save an average household up to $140 per year in energy bills.

Seasonal Considerations

Ottawa’s climate means homeowners should consider both cooling and heating performance:

Cooling: SEER ratings matter most during hot summers.
Heating: For heat pumps, check the HSPF (Heating Seasonal Performance Factor). For furnaces, look at the AFUE (Annual Fuel Utilization Efficiency) rating.

Choosing a balanced system ensures comfort and savings year-round.
