Kinghome R32 rooftop units: heating and cooling in one cabinet
Two 3 and 5 ton packaged heat pumps, ENERGY STAR cold climate certified. Everything is in the cabinet: it sits on a roof curb or a ground pad and connects to a duct system. Kinghome’s name for them: “R32 Rooftop Unit”.
Rated cooling (ENERGY STAR), rated heating at -8.3 °C (product page), circuit (MCA / MOP, in amps) and the amount on Hydro-Québec’s LogisVert list of Oct. 26, 2026.
LogisVert is for an existing home: read the LogisVert section before counting on it.

02 · Roof or ground
On the roof or on the ground: two installation methods, seven steps each.
The same cabinet connects from below (on a roof curb) or from the side (on a pad). Pick one: the manual’s steps show, with who does what.
Installation
On a roof curb, ducts from below
Licensed partnerInstall the roof curb and its flashing. The manufacturer does not supply the curb: the manual gives its reference dimensions (figure 7).
AirGreenBuild the supply and return ducts inside the curb, fastened to the curb and the building.
LiftingLift the unit by the rail lifting holes, with spreader bars, panels in place, cables attached 36 to 54 in (914 to 1,371 mm) above. Keep 1/4 in (6.4 mm) between the curb and the inner rail.
AirGreenSwitch the unit to vertical connection: the bottom opening covers come off.
AirGreenInstall the condensate drain with its trap.
AirGreenMake the electrical connections.
KinghomeDo the first start-up: per the manual, a Kinghome service centre technician or a person assigned by Kinghome, for the warranty to apply.
On a ground pad, ducts from the side
Licensed partnerPrepare the pad and the unit supports.
LiftingLift and set the unit, by the rail lifting holes, with spreader bars.
AirGreenSwitch the unit to horizontal connection: the side opening covers come off.
AirGreenBuild the ducts at the unit openings.
AirGreenInstall the condensate drain with its trap.

Neverinto a waste pipe that can send odours back, nor into a downspout: into a drain system meant for the unit, per the manual.
Manual, section 3.2.5.
03 · The ducts decide
Your ducts’ static pressure sets the fan speed.
The more the ducts hold the air back, the higher the static pressure. The manual gives, for each pressure, the allowed speeds and the airflow. Slide: the setting follows the pressure measured in your ducts.

Level 8speeds 8, 9, 10 and 12
Level 9speeds 9, 10, 11 and 13
Each level (4 to 9) gives four speeds: low, middle, high and super high. With a 24 V thermostat, the speed is set with the SA1 DIP switches. Manual, section 3.2.6.
Two tables, we follow the manual
The brochures claim 0 to 1.0 in W.C. and the submittals (Aug. 20, 2026) give a wider table, up to 1.0 in. The manual (Aug. 28, 2026) stops at 0.8 in, the unit’s test range, and forbids the cells outside its table. This page follows the manual, the most recent and strictest document.
The manual also marks with a bold frame the cells where electric backup is allowed; that frame cannot be read in the PDF text: the technician checks it in the manual.
The shop
Both rooftop units, right below.

Everything to know before installing a rooftop unit
Electric backup, cold, the trades involved, the warranty and LogisVert. Everything comes from Kinghome Canada documents, ENERGY STAR, Hydro-Québec and Environment Canada.
04 · Electric backup
Three backup kits: 6, 9 or 12 kW.
For the days when the heat pump is not enough, a heating element kit goes into the cabinet. It is electrical work: it falls within our licence (16).

Manual, section 3.4.1; LYQ-08 kit specification (Jan. 3, 2025); breakers from the 5 ton submittal (Aug. 20, 2026). The English brochure prints 5, 10, 15 and 20 kW for the 3 ton; the French brochure, both submittals, the manual and the specification say 6, 9 and 12 kW: we follow those five documents.
No factory element
Electric backup is an accessory, and only these three kits are allowed by the manual, for the 3 and 5 tons.
Its own circuit
The 5 ton submittal asks for an independent power supply, at 240 V. Copper wire only.
Fan first
The fan must run when the element heats, and the element must stop before the fan.
1 ft from combustibles
Per the manual, supply ducts within 5 ft of the heating element stay at least 1 ft from other combustibles and walls.
05 · In the cold
At -15 °C, the certificate shows more than at -8.3 °C.
ENERGY STAR publishes two figures: the rated heat at -8.3 °C (17 °F), the one Hydro-Québec reads for LogisVert, and the heat at -15 °C (5 °F). For these two units, the second figure is higher than the first. These are the certificate’s own figures, and our product pages carry them as is.

What Kinghome says
“Full heating capacity at -9.4°C and maintains 80% capacity at -15°C” (English brochure). ENERGY STAR publishes nothing at -9.4 °C. At -15 °C, the 3 ton keeps 85% and the 5 ton 89% of their rated heat at 8.3 °C: that half of the promise holds.
And in Montreal
-9.4 °C is about the January daily mean at Montreal-Trudeau (-9.2 °C, 1991-2020 normals). The January average daily minimum is -13.5 °C. The heating range goes down to -30 °C.

06 · Who does what
A rooftop unit involves several trades. Here are ours, and the others.
AirGreen holds RBQ licence 5645-9605-01, subcategories 15.8 (ventilation), 15.10 (refrigeration) and 16 (electrical). What falls outside these licences goes to a licensed partner.
AirGreen
AirGreen, licence 15.8
Ventilation: the supply and return ducts, their connection to the cabinet and the vertical or horizontal conversion.
AirGreen
AirGreen, licence 15.10
Refrigeration: the unit arrives assembled, piped and wired at the factory; any check or work on the R-32 circuit falls under this licence.
AirGreen
AirGreen, licence 16
Electrical: the unit’s supply, the backup kit circuit, the wired controller or the 24 V thermostat.
Partner
Licensed partner
The roofing: curb, flashing and membrane. It is not in our licences: a licensed roofer does it.
Partner
Engineer, if needed
The roof must carry the unit: 538 to 628 lb net per the brochure. The manual asks for a location strong enough for its weight and vibration.
Partner
Licensed plumber, if needed
If the condensate drain needs plumbing work in the building. Gas or oil: also handed to a licensed partner.
07 · Warranty
A commercial-use warranty, and three conditions in the manual.
The submittals give 5 years on parts and 7 years on the compressor for a registered unit, 5 and 5 otherwise (“Terms and conditions apply”). Labour is not covered by Kinghome.
The first start-up is done by a Kinghome service centre technician or a person assigned by Kinghome.
Only Kinghome spare parts are used.
The manual’s maintenance is done at the set frequency: filter, drain, heat exchanger, check before each season.
The manual adds that any breach voids the warranty.
RTU installation manual, section 7 “After-sales Service” and section 6 (maintenance); submittals of Aug. 20, 2026; 2025 Kinghome limited warranty (labour).
08 · LogisVert
On the LogisVert list, with one condition: a home.
Both units are on the LogisVert list “owner, existing home” of October 26, 2026, with the usual calculation: $120 per 1,000 BTU/h of rated heat at -8.3 °C.

09 · Frequently asked questions
Your questions about rooftop units.
Product-page figures are read live: when a product page changes, the answer follows. The others come from the dated documents at the foot of the page.
A packaged heat pump: compressor, coils and fan in one cabinet, assembled, piped and wired at the factory, with no refrigerant line set to run. It heats and cools through a duct system. Kinghome calls it “R32 Rooftop Unit” and the manual says it suits homes, offices and restaurants.
No. The manual plans two installs: on a roof curb, ducts from below, or on a ground pad, ducts from the side (see the steps).
No: 208-230 V single phase, 60 Hz, from 187 to 253 V. The circuit needs 35 A minimum and a breaker of 40 A maximum for the 3 ton, 39.1 and 45 A for the 5 ton, per the manual. A backup kit has its own circuit.
The manual allows a static pressure of 0 to 0.8 in W.C., with a fan speed set to match. Beyond that, the ducts must be reworked. Ducts must be sealed to the unit, insulated with a vapour barrier in unconditioned space, and the first 6 in of supply in sheet metal (NFPA 90B), per the manual.
R-32 is an A2L refrigerant, mildly flammable. The manual sets a minimum area for an unventilated room served: 12.7 m² (135.9 sq ft) for a 4.25 kg charge and 17.3 m² (185.5 sq ft) for 5.8 kg, at a 2.2 m height (the manual’s figures). Those two charges are the ones on the 3 and 5 ton submittals. It also requires continuous air circulation: the unit stays powered except for service.
Three kits exist: LYQ-08-F (6 kW), LYQ-08-G (9 kW) and LYQ-08-H (12 kW), at 240 V, for the 3 and 5 tons. The choice depends on the building’s heating need in deep cold (details).
One or the other, not both. The XE7C-23/H programmable wired controller is included; a 24 V thermostat connects instead, by setting the SA1 DIP switches. The submittal also mentions Modbus control and an included emergency stop switch.
538 lb net for the 3 ton (523 per its submittal) and 628 lb for the 5 ton, per the brochure. The manual asks for a location strong enough for the weight and vibration; if needed, an engineer confirms it before installation.
The brochure gives 65 dB(A) for the 3 ton and 68 for the 5 ton; the submittal and our product page give 63 for the 3 ton. On the Québec.ca scale, 60 dB is a normal conversation and 70 a busy street. The manual advises against installing it near a bedroom.
Because it is a packaged heat pump, all in one cabinet. At Kinghome, the word “Monobloc” also names another product, an air-to-water heat pump: the units on this page are what it calls “R32 Rooftop Unit”.
