Installation and distribution of the 3-ton YORK YH5 LX central heat pump throughout Greater Montreal.
Two-stage LX series, R-454B refrigerant, ENERGY STAR® certified, 10-year parts and compressor warranty.
The two-stage compressor changes how the home is heated. Instead of starting at full capacity and then stopping, the unit spends most of its time at the low stage: longer cycles, fewer starts, and more consistent temperatures from room to room.
Certified performance, not advertised performance. Paired with the YORK JHE36B5CD2SS1 blower cabinet, the YH536E2S11 is rated at 15.2 SEER2, 11.0 EER2, and 8.1 HSPF2 under AHRI certificate 214427016. It delivers 21,000 BTU/h at -8 °C and 17,600 BTU/h at -15 °C. Its 8.1 HSPF2 is the highest in the LX series: this is the combination that performs best over a full heating season.
YORK approves this series for heating down to -18 °C. Below that temperature, the backup heat source - electric heat or a furnace - takes over. We always size both systems together, after performing an actual home load calculation: an oversized central system costs more, has excessively short cycles, and dehumidifies poorly.
The blower cabinet is part of the system. The JHE36B5CD2SS1 is a 48.4-inch-high, 17.5-inch-wide, and 21.5-inch-deep unit with a constant-torque ECM motor, supplied with its thermostatic expansion valve and A2L detector factory-installed. It delivers 1200 CFM and can be installed in upflow, downflow, right-horizontal, or left-horizontal configurations - providing flexibility for installation in both basements and attics.
A flexible outdoor unit. It can be paired with a blower cabinet, an “A” coil, or a “cased coil,” and operates with a conventional thermostat - no proprietary control required. The fin-and-tube coil and baked-on salt-spray-resistant coating are designed for outdoor durability.
R-454B replaces R-410A. Its global warming potential is nearly 78% lower, and it is the refrigerant used in new equipment sold in Canada.
YORK heat pumps are also eligible for provincial and/or federal rebates, such as Chauffez Vert, Efficient Heat Pumps (Hydro-Québec), and Canada Greener Homes.
