01 · What only the LZAH1 does

The former XLTH, in six facts.

Facts from Fujitsu sheets, the ENERGY STAR list and the NEEP list. Sources are at the bottom of the page.

11,100 BTU/h

The 9,000 BTU/h delivers up to 11,100 BTU/h at -26 °C, at maximum capacity, according to Fujitsu.

Same indoor unit

It shares its indoor unit with the LZAS1. Only the outdoor unit changes the floor: -26 °C instead of -21 °C.

Heated base pan

A built-in heater keeps the base of the outdoor unit from freezing.

Cold climate ×3

All three sizes are ENERGY STAR Cold Climate certified.

2020

Launched in 2020, it replaced the RLS3H.

LZBH1

At Fujitsu, the pair we install carries the system name LZBH1.

02 · The R-410A generation

Eight R-410A series, from the coldest floor to the mildest.

Before R-32, Fujitsu wall units ran on R-410A. Each card gives the series’ heating floor; the LZAH1 is highlighted.

03 · The sizes

9,000, 12,000 or 15,000 BTU/h.

06 · Built in

What Fujitsu put in it.

Fujitsu lists this series among its retired models. It stays in AirGreen’s catalogue: we confirm availability at quote time, and show you its R-32 successor alongside.

Optional Wi-Fi: a wireless adapter, sold separately, adds app control.

The earlier LZAS indoor unit had built-in Wi-Fi; the LZBS unit we install needs the adapter.

Heater in the base of the outdoor unit, so defrost water doesn’t freeze.

No automatic cut-out in cold weather, according to Fujitsu, though output isn’t rated below the listed range.

Minimum heat mode: the room stays at 10 °C while you’re away.

Powerful mode: 20 minutes at maximum airflow and compressor speed.

Economy mode: the set point adjusts to avoid over-heating or over-cooling.

Energy Saving Program (ESP): the set point adjusts when the room stays empty, according to Fujitsu.

Quiet schedule for the outdoor unit.

Weekly timer and 24-hour timer.

Apple-catechin filter and ion deodorizing filter, according to Fujitsu.

11 · R-410A in Québec

R-410A: what the rules really say.

In Canada, what is capped is the total amount of HFCs, not the servicing of your heat pump. US dates are shown for comparison, in grey.

2017 · CA

Canada ratifies the Kigali Amendment, which targets an 85% cut in HFCs by 2036.

Jan. 2019 · CA

Canada’s HFC phase-down starts: the cap is 90% of the baseline.

Jan. 2021 · QC

Québec: GWP limits for some refrigeration equipment. Heat pumps are not covered.

Jan. 2024 · CA

Canada’s cap drops to 60% of the baseline, a 40% cut.

Jan. 2025 · CA+QC

A GWP limit of 750 for chillers, in Canada and in Québec. Still nothing for residential heat pumps.

Jan. 2025 · US

United States only: import deadline for residential R-410A products (EPA rule, per Fujitsu).

Nov. 2025 · QC

LogisVert requires ENERGY STAR certification, whatever the refrigerant.

Jan. 2026 · US

United States only: installation deadline for new residential R-410A systems (per Fujitsu).

Jan. 2029 · CA

Canada’s cap drops to 30% of the baseline.

Jan. 2034 · CA

Canada’s cap drops to 20% of the baseline.

Jan. 2036 · CA

Canada’s cap reaches 15% of the baseline, the targeted 85% cut.

Key point: In Canada, what is capped is the total amount of HFCs, not the installation or servicing of an R-410A heat pump. The US dates are shown for comparison only.

Servicing an R-410A heat pump in Québec

In Québec, you can have your R-410A heat pump serviced and repaired for its whole useful life.

Québec’s halocarbon regulation limits the GWP of refrigeration equipment and chillers, not that of residential heat pumps.

Only a person holding the attestation required by the regulation may install, service, repair, charge or drain the unit.

Refrigerant must never be released into the air. It is recovered before any repair or removal.

A leaking unit isn’t simply topped up. A leak test comes before any refill.

The regulation’s annual leak test targets air-conditioning equipment of 20 kW and more, a size no wall heat pump in these families reaches.

R-32 can’t go into an R-410A system. Fujitsu says it is not a drop-in replacement.

Indoor and outdoor units pair within the same generation. Plan a full-system replacement when the time comes.

Canada doesn’t ban R-410A. It caps the amount of HFCs: 60% of the baseline until 2028, then 30% from 2029.

Fujitsu warranty: 5 years parts and 7 years compressor, up to 12 years with online registration within 60 days and a Fujitsu Elite contractor. Labour isn’t covered by Fujitsu.

Register the unit online within 60 days of installation. That’s the condition for the extended warranty.
