YORK central heat pumps: YH5 or HH8, what sets them apart at the same tonnage

At −15 °C (5 °F), the HH8 keeps 72 to 82% of its certified heating capacity at 8.3 °C; the YH5 LX keeps 49 to 55%. The rest shows in your yard and basement: footprint, weight, electrical circuit, line sets.

YH5 · HH8

Where to start? Pick what matters to you.

HH8

The HH8 systems are ENERGY STAR cold-climate certified, and NEEP lists their maximum output down to −25 °C. The YH5 LX systems carry no such mention and are not on the NEEP list as of October 27, 2026.

See the HH8

HH8

With its side discharge, the HH8 is the shallowest central unit in our catalogue at 2, 3 and 5 tons. Clearances are not in the YORK documents we read: we check them at the visit.

Compare dimensions

YH5 LX

At 1.5 tons, our catalogue only has the YH5 LX: our HH8 starts at 2 tons. At 4 tons, our catalogue has the YH548; YORK also sells the HH860 for 4 and 5 tons with a capacity switch, but our listing shows it at 5 tons.

See the YH5 LX

HH8

The HH8 gets LogisVert’s cold-climate rate, the YH5 LX the base rate: up to $4,440 on Hydro-Québec’s list.

See the amounts

Not comparable

The YORK documents we read give no per-model sound level. YORK claims “as low as 54 dBA” for the HH8 and, for the YH5, “as low as 69 dBA” in its technical guide and “76 dBA or lower” on its product page, with no test conditions.

Everything to know · Central heat pumps

03 · The system

Outside, the YORK unit. Inside, the JHE air handler.

A YORK central heat pump is two units certified together under one AHRI number: the one in the yard and the one in the house, in the basement or a closet. LogisVert excludes an indoor unit or ducts installed outside the insulated envelope, in the attic for example.

Outside

YH5 LX

Top discharge, base from 24 × 24 in. (1.5 tons) to 35 1/4 × 31 3/4 in. (4 and 5 tons).
124 to 255 lb operating weight.
Crankcase heater and discharge muffler factory-installed on every model.

Outside

HH8

Side discharge: 13 to 17 5/7 in. deep, up to 57 1/2 in. tall (5 tons).
116.8 to 244.7 lb operating weight.
Crankcase heater and base-pan heater as standard; the YH5 guide mentions no base-pan heater.

Inside

YORK JHE air handler

Multiposition: upflow, downflow or horizontal; 21 in. deep at most.
Nine-speed ECM blower, MaxAlloy™ “A” coil, factory-installed TXV.
Total air leakage of 2% or less; 1 in. filter.
At 4 and 5 tons, optional JSE short cabinet: upflow only, 57 in. tall at most. That is a different pairing: its AHRI number and LogisVert eligibility are checked on the quote.

Thermostat: YORK lists conventional controls for both families, and ENERGY STAR lists no connected function for either.

04 · Deep cold

In deep cold, how much of its heating capacity each family keeps.

Four test points are published: 8.3 °C, −8.3 °C and −15 °C by ENERGY STAR; −25 °C by NEEP. Nothing is published between these points, and we don’t estimate any. The bar shows the share of the 8.3 °C capacity that remains.

According to ENERGY STAR; YORK prints 467 in the YH5 guide.

Up to 78% lower GWP than R-410A, according to YORK, with similar pressures.

RDSRefrigerant detection

YORK factory-installs a refrigerant detection system (RDS) on the relevant equipment, including the JHE air handler. Local codes may require extra training or equipment.

07 · Glossary

The words on the spec sheet, in plain language. Tap or click a card.

SEER2

Seasonal cooling efficiency under the current test method; the “2” sets it apart from the old SEER. The higher it is, the less cooling costs.

HSPF2

Seasonal heating efficiency, calculated for a climate region: region V stands for a colder climate than region IV. NEEP lists both for the HH8.

COP

Heat delivered divided by electricity used, at a given temperature. A COP of 2 gives twice as much heat as electricity.

Two-stage

The YH5’s scroll compressor, from 2 tons up, runs at two capacities.

Variable speed

The HH8’s inverter-driven compressor adjusts its speed continuously; YORK states 35 to 100% of capacity.

Air handler

The indoor section: blower, coil and, when needed, an electric heat kit.

AHRI number

The certificate of one exact pairing, outdoor and indoor unit. Hydro-Québec looks this number up in its LogisVert list.

ENERGY STAR cold climate

The ENERGY STAR mention for heat pumps that meet cold-weather performance criteria.

Frequently asked questions

What people ask us about YORK central systems.

YH5 or HH8: which one for a Montreal house?

If deep-cold heating matters most, the HH8: its matched systems are ENERGY STAR cold-climate certified and keep 72 to 82% of their heating capacity from 8.3 °C to −15 °C, compared with 49 to 55% for the YH5 LX. At 1.5 tons, our catalogue only has the YH5 LX: our HH8 starts at 2 tons. The tonnage is set at the free visit.

Do the YH5 and the HH8 use the same indoor unit?

At 2 and 3 tons, yes: the JHE24B5AC2SS1 and JHE36B5CD2SS1 serve both families. At 5 tons, our listings pair the YH560 with the JHE60D5CH2SS1 and the HH860 with the JHE60C5CH2SS1. Each matched system has its own AHRI number.

Can I keep my gas furnace?

YORK allows pairing the YH5 and the HH8 with a gas furnace, and for the HH8, even one of another brand. The indoor unit is then no longer the JHE on our list: LogisVert eligibility, the AHRI number and the amount of that combination are checked on the quote. Gas work goes to a partner holding the proper RBQ licence.

Why does the HH8 get more LogisVert than the YH5?

Hydro-Québec’s LogisVert guide sets $120 per 1,000 BTU/h at −8 °C for an ENERGY STAR cold-climate heat pump, and $50 for an ENERGY STAR heat pump. At 3 tons, the October 26, 2026 list gives $3,408 for the HH8 and $1,050 for the YH5 LX.
