In Montreal, HVAC MTL replaces wall-mounted heat pumps starting at $2,690 + taxes, including installation and a 10-year warranty. The final price depends on the unit’s capacity, model, and the complexity of the installation. If the unit qualifies, Hydro-Québec’s LogisVert program then reimburses $50 or $120 per 1,000 BTU/h of heating at -8°C.
Starting price: $2,690 + taxes, installation included
The figure we are displaying, $2,690 + tax , corresponds to the replacement of a wall-mounted heat pump, including installation and a 10-year warranty . This is the actual price, not a promotional price for the unit alone: it covers the removal of the old unit, the installation of the new indoor and outdoor units, the connection, and the commissioning.
Why talk about a “starting from” price? Because no two projects are exactly alike. A triplex in the Plateau neighborhood with an outdoor unit on the second floor doesn’t require the same work as a bungalow with a concrete slab foundation. Rather than publishing a table of approximate prices per capacity, we prefer to give you a firm price in less than 24 hours , calculated specifically for your property.
What affects the price of a wall-mounted heat pump
When two bids for a “12,000 BTU” differ by several hundred dollars, the difference almost always comes from the following.
| Element | Effect on price | What to check in the submission |
|---|---|---|
| Power (9,000 to 36,000 BTU) | The more powerful the device, the more expensive it is. | That the power is justified by the surface area and insulation |
| Model and brand | Significant difference between an entry-level range and a cold climate model | Minimum heating temperature (−25 °C or −30 °C), HSPF2, guaranteed |
| Pipe length | A longer distance between the two units requires more equipment and time. | Length included and price of each additional foot |
| Outdoor unit support | Slab, wall mount or raised stand do not have the same cost | Height relative to the snow, wall-mounted fixing |
| Electricity | Adding a dedicated circuit or a full panel may increase the price. | Who does the electrical work and is it included? |
| Access | High facade, roof, narrow alley | Access equipment provided or not |
| Removal of the old device | Refrigerant recovery and disposal | Included or extra |
To compare prices fairly, compare quotes that describe the same thing: same capacity, same pipe length, same type of support, and same warranty.
What our installation price includes
- A certified refrigeration technician from our team, under RBQ license 5845-4109-01.
- The installation of the two units, drilling, refrigerant piping and drain.
- Vacuum sealing, leak testing and commissioning in heating and air conditioning.
- A 10-year warranty is included.
- A detailed invoice containing the information requested by Hydro-Québec for LogisVert.
The price with subsidy: how LogisVert is calculated
In 2026, the Quebec subsidy for a heat pump will be administered through Hydro-Québec’s LogisVert program . The amount will depend not on the price paid, but on the heating capacity of the unit at -8°C (verified on October 16, 2026):
- $50 per 1,000 BTU/h at −8 °C for an ENERGY STAR certified heat pump;
- $120 per 1,000 BTU/h at -8°C for an ENERGY STAR certified “cold climate” type heat pump.
According to the LogisVert participation guide , the subsidy cannot exceed 100% of the purchase and installation cost before taxes, the outdoor unit must have a nominal air conditioning capacity of at least 12,000 BTU/h and the application must be submitted within nine months of installation (verified on October 16, 2026).
Table: Subsidy based on power at −8 °C
| Heating power at −8 °C | ENERGY STAR ($50 / 1,000 BTU/h) | ENERGY STAR cold climate ($120 / 1000 BTU/h) |
|---|---|---|
| 12,000 BTU/h | $600 | $1,440 |
| 18,000 BTU/h | $900 | $2,160 |
| 24,000 BTU/h | $1,200 | $2,880 |
These amounts are a simple calculation based on official rates. They do not correspond to a precise model, and that’s where many people go wrong.
Why doesn’t a “12,000 BTU” heater deliver 12,000 BTU/h at -8°C?
The number in a model name is its rated power. Hydro-Québec, however, calculates the subsidy based on the heating capacity at -8°C indicated in the appliance’s certification. For example, the manufacturer’s datasheet for the GREE Vireo shows a 12,000 BTU model with a heating capacity of 7,700 BTU/h at -8°C (17°F).
If a unit of this capacity at -8°C were ENERGY STAR cold climate certified, the calculation would be 7.7 × $120 = $924; if it were only ENERGY STAR, 7.7 × $50 = $385. The actual amount always depends on the certification details of the installed system. We will indicate this in your quote, and our LogisVert example page for the GREE Livo 12,000 BTU shows the complete reasoning.
Example of calculation before and after subsidy
Let’s take an installation billed at $2,690 before taxes, for an eligible unit whose heating capacity at −8 °C would be 12,000 BTU/h:
- Price before taxes: $2,690.
- Subsidy if the appliance is ENERGY STAR: $600, for a net cost of $2,090 before taxes.
- Subsidy if the appliance is ENERGY STAR cold climate: $1,440, or a net cost of $1,250 before taxes.
Taxes are applied to the full bill; the subsidy is paid later by Hydro-Québec to the homeowner. Therefore, it is not deducted from the bill on the day of installation. Also note: a less expensive entry-level model may receive a smaller subsidy than a cold-climate model. The best net price is not always that of the least expensive unit.
Does the price change between replacement and first installation?
Our starting price is for replacing a wall-mounted heat pump. In a replacement, the unit locations, wall penetration, and often the electrical connection are already in place. A new installation may require more: new drilling, new piping, and a new support structure. Conversely, if the old piping is incompatible with the new refrigerant or pipe diameter, it must be replaced.
If your current unit is broken, also request a repair assessment on our heat pump repair page before deciding: depending on the age and the breakdown, one or the other option may be the most reasonable.
The wall-mounted models that we install
Our catalog of wall-mounted heat pumps includes Gree, Stelpro, Ouellet, Elios, and Moovair models ranging from 9,000 to 36,000 BTU, many of which heat down to -30°C depending on the manufacturer. To help you choose:
- Small room or bedroom : 9,000 BTU, to be validated according to insulation.
- Open area of a condo or apartment : often 12,000 to 18,000 BTU.
- Large open ground floor : 18,000 to 24,000 BTU, or a multi-zone heat pump if several rooms are closed.
To estimate the required heating capacity for your home, consult our heat pump BTU calculation guide. An oversized heat pump is more expensive to purchase and less efficient; an undersized heat pump leaves the auxiliary heating system to do the job in very cold weather.
How to get the best price without any unpleasant surprises
- Request a written price that specifies the exact model (indoor and outdoor unit numbers).
- Verify that the quote specifies the included pipe length and the type of support.
- Confirm that the device is eligible for LogisVert and at what rate.
- Demand the contractor’s RBQ license number: this is a LogisVert requirement.
- Compare the full warranty: compressor, parts and labor.
- Keep your detailed invoice: it is used for the grant application and the guarantee.
Frequently Asked Questions
How much does a wall-mounted heat pump cost to install in Montreal in 2026?
At HVAC MTL, wall-mounted heat pump replacements start at $2,690 + tax, including installation and a 10-year warranty. The exact price depends on the unit’s capacity, model, piping length, mounting brackets, and accessibility. We provide a firm quote in less than 24 hours.
Is the LogisVert subsidy deducted from the bill?
No. You pay the full bill, then submit your application online to Hydro-Québec no later than nine months after installation. The subsidy is paid to the homeowner whose name appears on the bill and proof of ownership.
What is the LogisVert price for a 12,000 BTU wall-mounted heat pump?
It depends on the heating capacity at -8°C listed in the appliance’s certification, not on the “12,000” in the name. The rate is $50 per 1,000 BTU/h for an ENERGY STAR model and $120 for an ENERGY STAR cold climate model.
Does the price include the warranty?
Yes, our starting price includes a 10-year warranty. The exact terms (compressor, parts, labor) vary by brand and are listed on each product page.
