When comparing two quotes, write down the brand, model number, SEER/SEER2, and whether it’s ENERGY STAR certified. That simple grid often reveals that a “cheaper” quote is using lower‑efficiency equipment.
In Canada, the most useful label for comparing AC efficiency at a glance is the black‑and‑white EnerGuide label. For central air conditioners, Natural Resources Canada’s central AC EnerGuide documentation shows that this label prominently displays the unit’s SEER value, along with a horizontal scale indicating the range of SEER ratings available for similar models and a pointer marking where your specific model falls on that range, as described in Natural Resources Canada’s EnerGuide guide for central air conditioners. That visual “thermometer” helps you see instantly whether a unit sits at the low, middle, or high end of currently available efficiency.
On top of EnerGuide, many central ACs and heat pumps also carry the blue ENERGY STAR symbol. NRCan notes that ENERGY STAR certification for residential air conditioners requires higher efficiency thresholds than non‑certified units and that certified split systems must meet elevated SEER criteria, a point discussed in Natural Resources Canada’s Air Conditioning Your Home guidance. That means:
Here’s a quick mental checklist for using the label when you’re standing in front of a spec sheet or equipment quote:
You’ll see SEER or SEER2 in different places depending on the type of system:
When in doubt, ask your contractor to point out the SEER or SEER2 rating on the exact model and configuration they’re quoting, not just on a generic brochure.
When comparing two quotes, write down the brand, model number, SEER/SEER2, and whether it’s ENERGY STAR certified. That simple grid often reveals that a “cheaper” quote is using lower‑efficiency equipment.
