03 · SEER / SEER2

Why we do not compare SEER with SEER2.

The 2023 brochure gives SEER and HSPF, measured with the old method. Current series are rated in SEER2 and HSPF2. The calculator applies the same definition to the 2023 SEER values: heat removed over the season divided by the electricity used.

Two methods, two scales
ZE-24CA17 (2023 brochure)17.6 SEER
ZE-24CB25 (BRO_2606 brochure)22.5 SEER2

These two figures do not compare directly: SEER2 comes from a tougher test, with higher external static pressure (US DOE, Appendix M1, mandatory since January 1, 2023). In Canada, minimums are stated in SEER2 and HSPF2 since the same date.

Heat removed from the home over the summer (example)
3,000,000 BTU
ZE-09DA17 19.3 SEER155 kWh$17.27
ZE-12CA17 16.7 SEER180 kWh$20.06
ZE-18CA17 17.6 SEER170 kWh$18.94

Illustrative math: SEER (old method, DOE, Appendix M), like SEER2, is the heat removed over the season divided by the electricity used, in BTU per watt-hour. A SEER and a SEER2 do not compare directly. Cost at Hydro-Québec’s Rate D second-tier price (11.142¢/kWh since April 1, 2026), which applies if use exceeds the first tier (40 kWh per day, times the number of days in the period); below it, a kWh costs 7.065¢. Before taxes and access fees. Your home will have its own numbers.

Did you know?
14.3minimum SEER2 (heat pump)

Since January 1, 2023, a split heat pump made for Canada must reach at least 14.3 SEER2 and 6.0 HSPF2 (Region V); a split air conditioner, 13.4 SEER2.Source: SOR/2022-265, Canada Gazette, Part II, Dec. 21, 2022.

04 · LogisVert

Zephyr 18: no LogisVert. Here is why.

Hydro-Québec’s program follows simple rules, and the 2023 R-410A models do not fit them. Several current wall units, on the other hand, qualify by AHRI number.

Why no LogisVert
  • Since November 26, 2025, the unit must be ENERGY STAR certified. The Zephyr 18 models are not in the current ENERGY STAR list (Oct. 8, 2026).
  • The outdoor unit must also be at least 12,000 BTU/h.
With a current wall unit, same size
CB25 24,000$2,640
CB25 18,000$2,160
UB32 12,000$1,560
CB25 12,000$1,296
CB22 18,000$740

Amounts checked by AHRI number in Hydro-Québec’s tool (Oct. 6, 2026). Scale: $0 to $2,640.

06 · Electricity

How many watts at rated capacity?

The brochure ratings are enough to estimate the power drawn at test conditions. Pick a size and a mode: the meter follows.

Pick a size and a mode
Capacity (brochure)9,000 BTU/h
Rating (brochure)EER 11
Rated current (brochure)7.4 A
Math9,000 BTU/h ÷ 11 EER
Cooling · ZE-09DA17
818 W
Power draw818 W

Scale: 0 to 2,500 W. At the brochure’s test conditions, not in deep cold.

AirGreen math from the ratings printed in 2023: EER is cooling in BTU/h per watt used; COP is heat delivered per unit of electricity (1 W = 3.412 BTU/h). The rated current is the brochure’s; a variable-speed unit can draw more or less depending on the load.

Did you know?
2,021 Wheating (18,000)

In rated heating, the Zephyr 18 18,000 draws about 2,021 W for 20,000 BTU/h (COP 2.9), the series’ lowest COP; the 12,000, about 1,121 W.Source: TTI “ZEPHYR 18” brochure (2023); AirGreen math.

07 · Refrigerant

R-410A, still allowed in Canada.

The Zephyr 18 generation uses R-410A, an A1 (non-flammable) refrigerant with a GWP of 2,090. Current series moved to R-454B (CB25, UB32) and R-32 (CB22).

Global warming potential (GWP)
R-410AA12,090
R-32A2L675
R-454BA2L470

GWP and ASHRAE class per the EPA (SNAP, March 19, 2026). A1: non-flammable.

What R-410A is made of
50% R-3250% R-125

Composition per ASHRAE designations (410A: R-32/125, 50.0/50.0).

In Canada, no GWP limit applies to residential air conditioners and heat pumps: R-410A remains allowed (SOR/2016-137, Schedule 1.1, current to Apr. 28, 2026). In the United States, new residential equipment installed since January 1, 2025 must use a refrigerant with a GWP under 700, unless its components were made or imported before 2025; on May 21, 2026, the EPA removed the January 1, 2026 installation deadline for those components.
Did you know?

R-410A is an equal blend of R-32 and R-125. R-32 alone is the CB22’s refrigerant.Source: ASHRAE refrigerant designations.

11 · Warranty and installation

What the brochure said, and what the law says.

The 2023 brochure announced 10 years on parts and compressor. For a unit bought new on or after October 5, 2026, the law adds a 6-year warranty of good working order, counted from delivery.

Zephyr base warranty
10 years

on parts and compressor, per the 2023 ZEPHYR 18 brochure. We confirm the warranty on the quote.

Parts (Zephyr)
10 years
Legal warranty
6 years

For a heat pump or air conditioner bought new from a merchant on or after October 5, 2026, Quebec law adds a free, automatic 6-year warranty of good working order, counted from delivery (Office de la protection du consommateur). Under TTI’s parts policy (v3.4, July 17, 2026), labour to replace a part during that period falls on the installing contractor.

Certified technician

Service or repair by anyone not certified and authorized by TTI (or Kinghome) ends the manufacturer’s conventional warranty (TTI, s. 4.4).

Through your installer

If something breaks, you call the contractor who installed it; they file the claim with TTI.

Filters, every month

TTI’s policy asks owners to clean the indoor unit filters at least once a month (s. 6.3).
