When the owner of a small building asks us which one to choose, we always start with the same explanation: at equal capacity, these units share identical certified data. The choice therefore comes down to something else, the equipment and the control. This page covers the 2 ton \u003cstrong\u003eTOSOT TK-H02TC\/NhA-D(U)\u003c\/strong\u003e model, that is 24,000 BTU\/h nominal, and what its spec sheet puts forward.\u003c\/p\u003e\n\u003cp\u003eA \u003cstrong\u003epackaged heat pump\u003c\/strong\u003e brings the compressor, the coils and the fan together in a single outdoor cabinet. That cabinet connects to the building's duct system and delivers both \u003cstrong\u003eheating and air conditioning\u003c\/strong\u003e, with no indoor unit to house in a mechanical room. The TOSOT model runs on \u003cstrong\u003eR-32\u003c\/strong\u003e refrigerant and is fed in \u003cstrong\u003e208-230 V single-phase\u003c\/strong\u003e (1 phase, 60 Hz), which suits buildings that have no three-phase service. It is all-electric: no gas is required.\u003c\/p\u003e\n\u003ch3\u003eThe buildings a 2 ton is right for\u003c\/h3\u003e\n\u003cp\u003eThe 2 ton size targets small buildings served by a single duct system: a neighbourhood commercial space, a professional office, a workshop, a small branch or a house where all the air travels through the same distribution. In Montreal, Laval and Longueuil, these units often find their place on the flat roofs of small commercial buildings, where owners prefer to keep the equipment outside and free up the space indoors.\u003c\/p\u003e\n\u003cp\u003eFinal sizing still depends on your building: insulation, windows, occupancy and the condition of the ducts. That is why we do the estimate on site, before talking about a brand or a model. If the needs exceed what a 2 ton can deliver, the same TOSOT line also comes in 3, 4 and 5 ton.\u003c\/p\u003e\n\u003ch3\u003eGree, Kinghome or TOSOT: what the certificates say\u003c\/h3\u003e\n\u003cp\u003eThe three brands come from the same group: Kinghome presents itself as \"a member of GREE group\" and TOSOT is a Gree brand. We do not claim that the units are identical, but their certified data is, at equal capacity. In 2 ton, the TOSOT model posts the following values:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAHRI reference 218795633 and ENERGY STAR certificate 4706810, with the \u003cstrong\u003eENERGY STAR Cold Climate\u003c\/strong\u003e designation;\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSEER2 of 18.0\u003c\/strong\u003e, \u003cstrong\u003eEER2 of 11.7\u003c\/strong\u003e and \u003cstrong\u003eHSPF2 of 8.8\u003c\/strong\u003e (region IV), against an EER2 of 11.2 for the 3, 4 and 5 ton models;\u003c\/li\u003e\n\u003cli\u003e24,000 BTU\/h in cooling at 35 °C and 24,000 BTU\/h in heating at 8.3 °C;\u003c\/li\u003e\n\u003cli\u003e15,500 BTU\/h in heating at -8.3 °C (17 °F), the certified rated capacity;\u003c\/li\u003e\n\u003cli\u003e29,000 BTU\/h at -15 °C (5 °F), measured at maximum compressor speed, with a COP of 1.90.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe value at -15 °C is higher than the one at -8.3 °C, which can be surprising on a first read. The explanation lies in how they are measured: the capacity at -8.3 °C is the certified rated value, while the one at -15 °C is measured at maximum compressor speed, under the ENERGY STAR Cold Climate criterion. The two figures therefore do not describe the same operation and cannot be compared directly. The COP of 1.90 means that, under those conditions, the unit delivers 1.90 units of heat for every unit of electricity it draws.\u003c\/p\u003e\n\u003ch3\u003eWhat sets the TOSOT sheet apart\u003c\/h3\u003e\n\u003cp\u003eSince the certified figures are the same from one brand to the next at equal capacity, it is the items described in TOSOT's \"Submittal data\" sheet that guide the choice. Three points hold our attention when we advise a customer torn between the group brands.\u003c\/p\u003e\n\u003ch4\u003eThe TOSOT RS485 thermostat or a 24 V thermostat\u003c\/h4\u003e\n\u003cp\u003eThe unit accepts two control modes: the \u003cstrong\u003eTOSOT RS485 thermostat\u003c\/strong\u003e, or a standard 24 V thermostat from another manufacturer. The standard controller listed on the sheet is the XE7C-23\/H. For a small business that already has a 24 V thermostat in good condition, we check whether it can be kept. For a building starting from scratch, the brand's own thermostat keeps everything with a single manufacturer, which simplifies dealings with technical support.\u003c\/p\u003e\n\u003ch4\u003eThe Inverter rotary compressor with vapour injection (EVI)\u003c\/h4\u003e\n\u003cp\u003eTOSOT presents this model as a \"DC Inverter Rooftop Ultra Heat Fully Electric Heat Pump\", in other words a 100% electric heat pump. The unit is built around an \u003cstrong\u003eInverter rotary compressor with vapour injection (EVI)\u003c\/strong\u003e, managed by high-efficiency DC Inverter technology. Vapour injection is a compression technique associated with cold-weather heating, while the Inverter compressor varies its speed with demand. The sheet also publishes a range of 8,600 to 25,400 BTU\/h in cooling and 9,000 to 30,400 BTU\/h in heating at 8.3 °C, which shows how wide that modulation is.\u003c\/p\u003e\n\u003ch4\u003eThe 5 or 10 kW backup heat kits\u003c\/h4\u003e\n\u003cp\u003e\u003cstrong\u003eElectric backup heat kits\u003c\/strong\u003e of 5 kW or 10 kW are offered as an option on the 2 ton. They add a reserve of heat for deep cold, on top of the heat pump. The 15 and 20 kW kits, for their part, are reserved for the 4 and 5 ton models. The choice between 5 and 10 kW is made with you, based on the building's needs and the capacity available at the electrical panel.\u003c\/p\u003e\n\u003cp\u003eThe TOSOT sheet also describes an electronic expansion valve, a centrifugal indoor blower and an aluminum air filter. We mention them because they are part of the documented equipment, not to set them against the other brands of the group: to compare two quotes, rely on the AHRI and ENERGY STAR references of each unit.\u003c\/p\u003e\n\u003ch2\u003eThe TK-H02TC on your roof: dimensions, connection and installation\u003c\/h2\u003e\n\u003ch3\u003eA compact cabinet for a small roof\u003c\/h3\u003e\n\u003cp\u003eThe 2 ton measures 44 × 35-7\/16 × 49-1\/4 in. (1,120 × 900 × 1,250 mm), in width, depth and height. It weighs 523 lb net and 545 lb gross, and holds 150 oz of R-32 refrigerant. On a flat roof, we check the load-bearing capacity of the structure and the access for handling before confirming the location with you.\u003c\/p\u003e\n\u003ch3\u003eVertical or horizontal duct connection\u003c\/h3\u003e\n\u003cp\u003eThe ducts connect vertically, through the bottom of the unit, or horizontally, through the side. The vertical connection is made on a roof curb whose dimensions TOSOT publishes; the side connection suits cases where the ducts come in through a wall. The installation clearances published in the spec sheet are respected on every job, both for access during maintenance and for air circulation around the cabinet.\u003c\/p\u003e\n\u003ch3\u003eAirflow, static pressure and sound level\u003c\/h3\u003e\n\u003cp\u003eThe centrifugal indoor blower offers three airflows: 880, 700 and 600 CFM (high, medium and low speed). External static pressure is 0.5 in. as standard and can reach 0.7 in. at maximum, a useful figure when reusing an existing duct system whose resistance is unknown. The published sound pressure is 65 dB(A): we take it into account to place the unit away from neighbouring windows and terraces when the roof allows.\u003c\/p\u003e\n\u003ch3\u003eElectrical supply and operating range\u003c\/h3\u003e\n\u003cp\u003eOn the electrical side, the sheet lists an MCA of 35.0 A and an MOCP of 40.0 A, at 208-230 V single-phase. Your electrician sizes the circuit from those values; the backup heat kit, if you choose one, also has to be planned for at the panel. The unit heats at outdoor temperatures from -30 °C to 24 °C and cools from -5 °C to 52 °C. This \u003cstrong\u003eheating down to -30 °C\u003c\/strong\u003e comes on top of the \u003cstrong\u003eENERGY STAR Cold Climate\u003c\/strong\u003e certification, obtained for every capacity in the line.\u003c\/p\u003e\n\u003ch3\u003eHow we help you choose\u003c\/h3\u003e\n\u003cp\u003eBetween two brands with identical certified data, the decision rests on concrete criteria.

When that unit reaches the end of its life, the question comes up: replace it with the same type of equipment, or switch to electricity. The \u003cstrong\u003eTOSOT TK-H03TC\/NhA-D(U)\u003c\/strong\u003e model answers the second option. TOSOT, a brand of the Gree group, describes it as a \"DC Inverter Rooftop Ultra Heat Fully Electric Heat Pump\": an all-electric \u003cstrong\u003epackaged heat pump\u003c\/strong\u003e, which needs no gas, and which delivers heating as well as air conditioning from a single outdoor cabinet.\u003c\/p\u003e\n\u003cp\u003eLike the old rooftop unit, this cabinet brings together the compressor, the coils and the fan, then connects to the building's duct system. The difference lies in the heat source: instead of a burner, an \u003cstrong\u003eR-32\u003c\/strong\u003e refrigeration cycle draws heat from the outdoor air to move it inside in winter, and reverses the process in summer. This 3 ton \u003cstrong\u003eRooftop R32\u003c\/strong\u003e posts a rated capacity of \u003cstrong\u003e36,000 BTU\/h\u003c\/strong\u003e.\u003c\/p\u003e\n\u003ch3\u003eWhat the conversion changes for your building\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eNo more gas supply or propane tank for this unit: the heat pump runs on electricity alone.\u003c\/li\u003e\n\u003cli\u003eNo combustion in the cabinet, so no combustion products to vent on the roof.\u003c\/li\u003e\n\u003cli\u003eA \u003cstrong\u003e208-230 V single-phase\u003c\/strong\u003e supply (1 phase, 60 Hz), which suits buildings with no three-phase service, with an MCA of 35.0 A and an MOCP of 40.0 A according to the spec sheet.\u003c\/li\u003e\n\u003cli\u003eAir conditioning in the same unit, from -5 °C to 52 °C outdoors, with a \u003cstrong\u003eSEER2 of 18.0\u003c\/strong\u003e and an EER2 of 11.2.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe old gas or propane connection stops being used. Taking it out of service is planned with the qualified trades before the heat pump goes in, and we factor that into the project schedule.\u003c\/p\u003e\n\u003ch3\u003e36,000 BTU\/h nominal: reading \"3 ton\" correctly\u003c\/h3\u003e\n\u003cp\u003eThe name \"3 ton\" refers to the rated capacity of 36,000 BTU\/h. The certified values, the ones that appear on AHRI certificate 218471411 and ENERGY STAR certificate 4624791, are 34,000 BTU\/h in cooling at 35 °C and 34,000 BTU\/h in heating at 8.3 °C. We base our calculations on the certified values; the rated value mainly serves to name the size.\u003c\/p\u003e\n\u003cp\u003eBecause the compressor uses DC Inverter technology, capacity varies with demand. The TOSOT sheet publishes a range of 8,600 to 36,100 BTU\/h in cooling and 9,000 to 39,600 BTU\/h in heating at 8.3 °C. On the mild days of spring and fall, the unit can therefore run at the bottom of its range instead of starting and stopping endlessly.\u003c\/p\u003e\n\u003cp\u003eOne point deserves particular attention during a conversion: the capacity of the old burner must not be copied over as is. A gas rooftop unit was often chosen on other criteria, sometimes with a generous margin. We calculate the real heat losses of the space instead, then we check that the 3 ton, with or without backup heat, covers those needs.\u003c\/p\u003e\n\u003ch3\u003eHeating without gas through the Quebec winter\u003c\/h3\u003e\n\u003cp\u003eThe main worry for owners leaving gas behind is the deep cold. This model is \u003cstrong\u003eENERGY STAR Cold Climate certified\u003c\/strong\u003e and runs in heating mode at outdoor temperatures from -30 °C to 24 °C. The certified data gives two reference points:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e21,800 BTU\/h at -8.3 °C (17 °F), the certified rated capacity at that temperature;\u003c\/li\u003e\n\u003cli\u003e29,000 BTU\/h at -15 °C (5 °F), measured at maximum compressor speed, with a COP of 1.90.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe second figure is higher than the first because it does not measure the same thing: one is a rated value, the other corresponds to the compressor pushed to its maximum speed, as the ENERGY STAR Cold Climate criterion requires. The COP of 1.90 indicates that at -15 °C the unit delivers 1.90 units of heat for every unit of electricity it draws. The Inverter rotary compressor with vapour injection (EVI) is part of the equipment TOSOT describes for this \"Ultra Heat\" model, which delivers \u003cstrong\u003eheating down to -30 °C\u003c\/strong\u003e.\u003c\/p\u003e\n\u003ch3\u003eThe optional 5 or 10 kW electric backup heat\u003c\/h3\u003e\n\u003cp\u003eA gas rooftop unit gave the impression of a reserve of heat always on hand. To get that margin back, TOSOT offers optional \u003cstrong\u003eelectric backup heat kits\u003c\/strong\u003e of 5 kW or 10 kW on the 3 ton. These kits are electric heat strips: they turn electricity into heat without the effect of the heat pump, and therefore serve as a supplement during deep cold rather than as the main source.\u003c\/p\u003e\n\u003cp\u003eThe choice between 5 and 10 kW depends on the heat loss calculation and on the capacity available at the electrical panel, since the kit adds its own load to the circuit. The 15 and 20 kW kits are offered only on the 4 and 5 ton models; if your space needs one, it is often a sign that the capacity of the unit itself has to be reviewed.\u003c\/p\u003e\n\u003ch2\u003eReusing the location and the ducts of the old unit\u003c\/h2\u003e\n\u003cp\u003eIn most conversions, the goal is to keep what already works: the opening in the roof, the duct system and, if possible, the control. Here are the points we check before confirming that the TK-H03TC can take the place of your rooftop unit.\u003c\/p\u003e\n\u003ch3\u003eRoof curb and vertical or horizontal connection\u003c\/h3\u003e\n\u003cp\u003eThe cabinet measures 44 × 35-7\/16 × 49-1\/4 in. (1,120 × 900 × 1,250 mm), in width, depth and height. TOSOT publishes the dimensions of the roof curb: we compare them with the existing curb to find out whether it can be kept or whether an adaptation is needed. The ducts connect vertically, through the bottom, or horizontally, through the side, which makes it possible to follow the old unit's configuration in many cases. The installation clearances published in the spec sheet are respected around the cabinet.\u003c\/p\u003e\n\u003ch3\u003eWeight and roof structure\u003c\/h3\u003e\n\u003cp\u003eThe heat pump weighs 523 lb net and 545 lb gross, and holds 150 oz of R-32 refrigerant. We compare that weight with the one of the unit being removed and we check the condition of the structure and of the curb before setting it in place. Getting it up to the roof is part of the planning we prepare with you.\u003c\/p\u003e\n\u003ch3\u003eAirflow and static pressure on existing ducts\u003c\/h3\u003e\n\u003cp\u003eA duct system designed for a gas rooftop unit was not always sized for a heat pump. The centrifugal indoor blower on the 3 ton moves 1,120, 800 or 700 CFM depending on the speed (high, medium, low), with an external static pressure of 0.5 in. as standard and up to 0.7 in. at maximum. We measure the existing system to confirm that these values suit it, and we flag the sections to correct where needed.

These figures do not compare directly: the values at 8.3 °C and at -8.3 °C are certified reference capacities, while the value at -15 °C is measured at maximum compressor speed, under the ENERGY STAR Cold Climate criterion. In the same way, the 62,700 BTU\/h represent the top of the modulation range published at 8.3 °C, not the certified value. To size backup heat, we therefore look at the capacity the heat pump holds at the design temperature for your area, then at the gap with the building's heat loss. The COP of 2.00 means that at -15 °C, the unit delivers 2.00 units of heat per unit of electricity it uses.\u003c\/p\u003e\n\u003ch3\u003eFour backup heat kits offered on the 4 ton\u003c\/h3\u003e\n\u003cp\u003eThe 5 and 10 kW kits exist across the whole TOSOT range, from the 2 to the 5 ton.

They turn electricity into heat without the effect of the heat pump, which draws its heat from the outdoor air. Backup heat therefore acts as a supplement during deep cold, not as the main source, and every kilowatt added is one more load on the panel. That is why we never choose a kit without first looking at the building's electrical service.\u003c\/p\u003e\n\u003ch3\u003eThe heat pump circuit: MCA 39.1 A and MOCP 45.0 A\u003c\/h3\u003e\n\u003cp\u003eThe TOSOT specification sheet gives, for the 4 ton, an \u003cstrong\u003eMCA of 39.1 A\u003c\/strong\u003e and an \u003cstrong\u003eMOCP of 45.0 A\u003c\/strong\u003e, in \u003cstrong\u003e208-230 V single-phase\u003c\/strong\u003e (1 phase, 60 Hz). The MCA, or minimum circuit ampacity, is used to determine the conductor size. The MOCP is the maximum rating of the breaker or the fuses protecting that circuit. Those two values let your electrician plan a compliant circuit for the heat pump itself.\u003c\/p\u003e\n\u003cp\u003eThe single-phase supply is an advantage for many small commercial buildings and multiplexes in Montreal, Laval and Longueuil that have no three-phase service. It does not, however, remove the need to check the total capacity of the electrical service, above all if a backup heat kit is added to the project.\u003c\/p\u003e\n\u003ch3\u003ePlanning the panel with your electrician\u003c\/h3\u003e\n\u003cp\u003eHere is the process we follow with the project's electrician before confirming the choice of kit:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003etake stock of the capacity of the electrical service and of the loads already connected: water heater, baseboards, kitchen or workshop equipment;\u003c\/li\u003e\n\u003cli\u003ereserve the heat pump circuit according to the MCA of 39.1 A and the MOCP of 45.0 A;\u003c\/li\u003e\n\u003cli\u003eadd the load of the kit under consideration, 5, 10, 15 or 20 kW, according to the manufacturer's data;\u003c\/li\u003e\n\u003cli\u003eaccount for the circuits freed up if the heat pump replaces electric baseboards;\u003c\/li\u003e\n\u003cli\u003eif the available capacity is not enough, choose a smaller kit or plan an upgrade of the electrical service;\u003c\/li\u003e\n\u003cli\u003ecoordinate the order of the work between the electrician and our installation crew.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThat planning avoids ordering a kit the panel could not feed, or having to rework the connection once the unit is set on the roof.\u003c\/p\u003e\n\u003ch2\u003eConnecting the 4 ton to vertical or horizontal ducts\u003c\/h2\u003e\n\u003cp\u003eThe TK-H04TC connects to the ducts in two ways, which leaves room to adapt to the building rather than the other way around.

In an existing building, we compare the published dimensions with the opening and the curb in place, if there is one, in order to determine the roofing work required before the unit is delivered.\u003c\/p\u003e\n\u003ch3\u003eClearances to respect around the cabinet\u003c\/h3\u003e\n\u003cp\u003eThe technical sheet publishes the installation clearances to allow for around the unit. We respect them on every installation: they ensure access for maintenance and the free circulation of air around the cabinet. On a commercial roof that already holds other equipment, this point often guides the choice of location. We also take into account the published sound pressure of 68 dB(A), keeping the unit away from windows and neighbours when the roof allows, as well as snow accumulation on the roof.\u003c\/p\u003e\n\u003ch3\u003eWeight, dimensions and handling\u003c\/h3\u003e\n\u003cp\u003eThe cabinet measures 44 × 44 × 49-1\/4 in. (1,120 × 1,120 × 1,250 mm), in width, depth and height. It weighs 629 lb net and 650 lb gross, and holds 205 oz of R-32 refrigerant. Before installation, we check that the roof structure can take that load at the planned location and we plan the handling up to the roof according to the access to the building.\u003c\/p\u003e\n\u003ch3\u003ePower supply and control\u003c\/h3\u003e\n\u003cp\u003eThe technical sheet lists an MCA of 39.1 A and an MOCP of 45.0 A, in 208-230 V single-phase (1 phase, 60 Hz). We pass these values on to your electrician for the preparation of the circuit, adding the load of the backup kit if you choose one. For control, the unit accepts a standard 24 V thermostat from another manufacturer or the TOSOT RS485 thermostat; the standard controller listed in the sheet is the XE7C-23\/H. In a store, we place the thermostat where it reads a temperature representative of the room, away from the doors and the display windows.\u003c\/p\u003e\n\u003ch3\u003eHow a project unfolds with our team\u003c\/h3\u003e\n\u003cp\u003eFor a commercial project of this size, here is how we proceed:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ea visit to the space, measurements and inspection of the duct system and of the diffusers;\u003c\/li\u003e\n\u003cli\u003ecalculation of the heating and cooling needs according to the volume, the occupancy and the building envelope;\u003c\/li\u003e\n\u003cli\u003ea roof plan: location, roof curb, clearances and vertical or horizontal connection;\u003c\/li\u003e\n\u003cli\u003ecoordination with your electrician for the circuit and any backup kit;\u003c\/li\u003e\n\u003cli\u003einstallation by our technicians, connection to the ducts and start-up;\u003c\/li\u003e\n\u003cli\u003ean explanation of the settings and of the thermostat to the manager of the space.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIf your project calls instead for a smaller capacity, or if you want to compare the brands of the Gree group, our \u003ca href=\"\/en\/collections\/thermopompe-monobloc-installation-partout-a-montreal-laval-longueuil-rive-sud-et-rive-nord\"\u003epackaged heat pumps\u003c\/a\u003e page presents the Rooftop R32 models we install, from 2 to 5 tons.\u003c\/p\u003e\n\u003ch3\u003eLet's talk about your large space\u003c\/h3\u003e\n\u003cp\u003eWe install the \u003cstrong\u003e5 ton TOSOT packaged heat pump\u003c\/strong\u003e in the stores, workshops and halls of Montreal, Laval, Longueuil, the North Shore and the South Shore. 100% free on-site estimate everywhere in Montreal, Laval, Longueuil, North Shore and South Shore: call AirGreen at 514 316-2973 to have your space, your roof and your ducts assessed by our team.
