01 · Is it right for me?

Central heat pump, add-on or wall units? Four answers are all it takes.

Your ducts, your current heating, your home, your priority. Sometimes the right answer is wall units, and we’ll tell you so right away.

1. Your air ducts
2. Your current heating
3. Your home
4. Your priority
Our take
Complete central system or add-on to your electric furnace
Your furnace can stay as backup, or make way for a new indoor unit.
The grant
LogisVert: $120 per 1,000 BTU/h at -8 °C for cold climate, $50 for standard ENERGY STAR.
The technical side
We check your duct airflow, the electrical panel and where the outdoor unit will go.
Watch out for
The complete system must be ENERGY STAR certified; the claim must be filed within 9 months.

02 · How it works

How a central heat pump works, in one diagram.

One unit outside, one unit inside the house, your ducts in between. In winter, it pulls heat from the outdoor air; in summer, it does the opposite.

BasementGround floorUpstairs-20 °Coutdoor airOutdoor unitcaptures heat from the airrefrigerantIndoorunitWinter: warm air in every room
Simplified illustration. In winter, the refrigerant carries heat from the outdoor air to the indoor unit, which blows it into the ducts.
Mode
Tap a component
Outdoor unit (condenser and compressor)
In winter, it captures heat from the outdoor air, even at -30 °C with cold-climate models, and pushes it into the house. In summer, it sends the house’s heat outside.

Heating and cooling the whole house with ducts: the central heat pump is the most versatile solution, and the only one of the two central options that qualifies for LogisVert.
Wall-mounted heat pump
Ideal for one specific area: living room, upstairs, condo, extension. Quick to install, no ducts. For a whole house you often need several units, which can cost almost as much as a central system, with less even distribution.
Wall-mounted heat pump installed
Wall-mounted heat pump installed
Central air conditioner
Uses the existing ducts, but only cools. In winter, an electric or gas furnace or baseboards do the heating. A good choice when your heating is already efficient, less economical in the long run.
Central heat pump
The most versatile: a single system heats and cools through the ducts. It replaces or works alongside the furnace, heats in deep cold with a model built for Québec, and qualifies for LogisVert.
The main advantages
Even comfort. Every room at the same temperature, no cold corners or overheated rooms.
One system. Heating in winter, cooling in summer, same ducts.
Less electricity. The Inverter compressor adjusts its output. AirGreen benchmark: 20 to 40% less on your Hydro-Québec bill depending on the house; run the numbers for yours in section 05.
Quiet. The noise stays outside; inside, you only hear air through the vents.
Resale value. A modern central system is a selling point.
Healthier air. A filter, humidifier or purifier can be added on the same ducts.

The limits to consider
Upfront investment. Higher than a wall unit; LogisVert covers part of it.
Ducts required. Existing and in good shape. Otherwise, plan for corrective work.
Demanding installation. RBQ and CMEQ licences, blower calibration: one mistake gets expensive.
Regular maintenance. Filters, coils and components need checking to keep the efficiency.

05 · Heating cost

How much a central heat pump takes off your winter bill.

Same heating need, two ways to produce it. Slide, change the efficiency, and see the gap over one winter and over ten.

Home heating need
18,000 kWh
Rule of thumb: the winter jump in your Hydro-Québec bills. Example value.
Heat pump efficiency (HSPF2)

Method: HSPF2 ÷ 3.412 gives the seasonal efficiency; we take off 20% to be safe, since a Montréal winter is harsher than the rating’s reference region. kWh price: 11.142¢, 2nd tier of Rate D (April 1, 2026). No rate increase, no cooling.

Estimated savings per winter

06 · Price

Central heat pump prices in 2026: what you really pay.

The price isn’t just the machine: it’s 15 to 20 years of comfort. Be wary of prices that are too low; a botched installation costs more over 10 years.

Market prices 2012–2026
AirGreen benchmarks from our own quotes, before grants.
2012 · basic central model, installedfrom $2,500
2026 · high-performance model, properly installed$3,500 to $6,500
2026 · replacing the heat pump only$3,000 to $7,000
$0$2,500$5,000$7,500
Why prices are rising: inflation, labour, materials, and above all new technology (R-32 / R-454B, Inverter, Wi-Fi, self-diagnostics). A complete installation with ductwork is always assessed case by case.
Why two quotes differ

A higher-rated cold-climate model can cost less net than a non-eligible entry-level model.
AirGreen tips
Compare the net price after the grant. A mid-range or high-end model with a good grant can end up cheaper than a basic unit.
Check the real warranties. Parts, compressor and labour: read the exclusions.
Insist on RBQ and CMEQ licences. A proper installation protects the lifespan and the warranty.
Think long term. Parts availability, brand reliability, speed of service.

08 · The 24 brands

Best central heat pump brands in Québec: all 24 put under the microscope.

Japanese brands, the Midea family, the Gree family, American brands: filter by family. When we sell a model, its certified spec sheet speaks louder than its reputation.

Who makes what: the family map
Several brands share the same manufacturer or platform. Based on our field and distribution experience.
In 2026, all new central units are moving to R-32 or R-454B and to SEER2, HSPF2 and EER2 ratings. The gaps are widening: some brands shine for their durability in our climate, others win you over on price, with more service calls.

09 · Deep cold

Central heat pumps and Québec winters: which ones still heat at -30 °C?

In Québec, a central unit has to heat at -25 °C and -30 °C. Most generic models lose their efficiency from -15 °C and are no longer enough as a main heating source. Bring the thermometer down.

Outdoor temperature
-25 °C
9 of 13 models are still rated to run at -25 °C.
Our pick for deep cold: Midea EVOX G3. In the 3-ton size, it keeps up to 27,600 BTU/h at -30 °C, with a COP of 1.56: it still delivers more than one and a half times the electricity it uses as heat. See the product
What sets a good cold-climate model apart
Multi-stage Inverter compressor. Adjusts its output continuously: steady and economical.
Base pan heater. Keeps the condensate from freezing.
Smart defrost. Only when needed: fewer stops, lower consumption.
High HSPF2. A sign of heating efficiency over the whole winter.
Capacity maintained in the cold. Check the capacity at -8 °C and at -15 °C on the spec sheet.
ENERGY STAR “Cold Climate” criteria: a COP of at least 1.75 at -15 °C and at least 70% of capacity retained at -15 °C.
The AirGreen edge: more than the brochure
  • Analysis of real performance curves.
  • Reliability tracked over several Québec winters.
  • Real service data from Greater Montréal.
For a main heating source, we favour models rated down to -30 °C.

10 · Sizing

What size central heat pump does my home need?

Capacity in tons and BTU, and why real comfort depends as much on proper sizing as on the brand.

Heated area
1,800 sq ft
Your home
1 ton = 12,000 BTU/h. Our estimators’ starting point: about 18,000 BTU/h per 1,000 sq ft, then adjusted on site; a poorly insulated century-old house can need up to 30% more than a new build. The often-quoted rule (2 tons for 900 to 1,200 well-insulated sq ft) is very limited: two houses of the same size don’t have the same needs. A load calculation (Manual J method) remains the reference; proper sizing extends the lifespan and maximizes the grant.

≈ 32,400 BTU/h of estimated need, rounded to a market size
Too big, too small or just right?
outputtime
Properly sized: the Inverter modulates its output smoothly; steady temperature, dry, comfortable air.
Real comfort depends as much on output as on airflow (variable-speed blower, sealed ducts), steady cycles (Inverter), dehumidification and even distribution.

Central heat pump noise levels: where does yours land?

AirGreen benchmarks: 40 to 55 dB for the indoor blower, 55 to 70 dB for the outdoor unit. To the ear, +10 dB sounds about twice as loud; +3 dB is twice the energy, not twice the perceived noise.

TCL APEX XS: 54.0 dB outdoors
Indoor unit (blower): 40 to 55 dB; with variable speed or Inverter, it adjusts the airflow and stays quiet.
Outdoor unit 55 to 60 dB: quiet, suited to urban areas.
Outdoor unit 65 to 70 dB: standard, but can be a nuisance near a patio or a bedroom. High-end models have sound-insulated cabinets.
Strange noises or vibrations: what to check
Strange noises or vibrations: what to check
Location
Away from bedroom windows and balconies, yours and your neighbour’s.
Resonance
An anti-vibration pad or slab cuts the noise transmitted into the house.
Inverter
At low speed most of the time: much quieter than an on/off unit.
Build quality
An insulated cabinet and a well-designed fan reduce vibration.
Well chosen and well installed, a central unit stays discreet, for you and for your neighbours.
12 · Refrigerants and ratings

R-32, R-454B, SEER2, HSPF2: the 2026 standards made simple.

Two ratings are enough to judge a model, and one number for its climate footprint.

SEER2, HSPF2, EER2: how to read a spec sheet
SEER2 · Cooling over a whole season. The higher it is, the less summer costs.
HSPF2 · Heating over the whole winter. The rating that matters most in Québec.
EER2 · Cooling efficiency in high heat (35 °C outside).
Since January 1, 2023, ratings follow the M1 test method, closer to real-world use. They often look 5 to 15% lower than the old ones, with no real loss: a SEER 22 unit is rated about SEER2 20.
7.8 ENERGY STAR
8.1 Cold Climate
Zephyr R-454B : HSPF2 10.5, above both thresholds, certified Cold Climate.
ENERGY STAR v6.2, ducted split system: SEER2 ≥ 15.2, EER2 ≥ 11.0, HSPF2 ≥ 7.8. Cold Climate: HSPF2 ≥ 8.1.
From R-410A to R-32 and R-454B
R-410AGWP 2,088
R-32GWP 675
R-454BGWP 466
R-32 cuts global warming potential (GWP) by about 68%, R-454B by about 78% (IPCC AR4). Better heat transfer, more compact units, lower consumption, simpler maintenance.
Not backward compatible. You can’t put R-32 or R-454B into an R-410A system. They are A2L refrigerants, mildly flammable: installation by a refrigeration technician trained in their safety rules.
Manufacturers have switched to these refrigerants; an R-410A unit that has already been manufactured can still be installed and repaired.

14 · Lifespan and maintenance

Central heat pump lifespan and maintenance.

Even an excellent central unit wears out faster without maintenance. See the effect, then plan your filters.

Lifespan: 15 to 20 years, if…
0 years
5 years
10 years
15 years
20 years
Maintained: aim for 15 to 20 years, manufacturer’s warranty preserved.
AirGreen benchmarks: a well-maintained central unit aims for 15 to 20 years; neglected, it can lose up to 25% of its efficiency in 5 years.
What makes a central unit last
Anti-corrosion coating. Humidity, road salt, pollution: essential near the river or in the city.
Inverter compressor. Fewer starts, less wear.
Parts available in Québec. A well-distributed brand gets fixed in days, not weeks.
Installation and follow-up. A well-installed, well-maintained mid-range unit often outlasts a neglected high-end one. That’s often the difference between a unit that quits after 7 years and one that goes past 20.
Reliability and durability
Reliability and durability
Maintenance: who does what
You
  • Clean or replace the filters every 1 to 3 months.
  • Keep grilles and air vents clear.
  • Avoid sudden setpoint jumps (18 °C to 24 °C all at once).
AirGreen, once a year
  • Pressure and refrigerant charge readings.
  • Inspection of the fan, compressor and blower.
  • Defrost and electrical connection checks.
  • Coil cleaning and, if needed, duct cleaning.
This preventive follow-up sharply reduces the risk of costly breakdowns and keeps the manufacturer’s warranty valid.
Your filters: how often?
Every 1 to 3 months depending on the season, pets, dust and pollen.

AirGreen expertise
  • Recommendations suited to your setting: a house near the river needs more follow-up than a new condo in Laval.
  • Advanced diagnostic tools: thermal camera, precise pressure tests.
  • Programming tips: lower it slightly at night for comfort and for the bill.
  • Preventive accessories: high-efficiency filters, anti-vibration protection, anti-corrosion treatments.
The result: a reliable, quiet and economical central unit, year after year.

The dangers of an uncertified installer
  • Manufacturer warranty refused or voided.
  • Premature breakdowns: sloppy connections, no pressure test.
  • Improvised wiring: risk of major failure or fire.
  • Hidden costs: the “cheapest” ends up costing thousands in repairs.
  • A contractor you can’t find after a few months.
Risky installation
Risky installation
Real examples of bad installations
Unlicensed subcontractor: warranty refused, parts not covered.
Poorly sized or poorly insulated ducts: freezing rooms, others overheated.
Badly placed outdoor unit: vibration in the house, noise for the neighbours.
Uncalibrated blower: airflow too strong or too weak, constant discomfort.
A careless installation can cancel every promise of efficiency and comfort.

16 · 2026 grants

Central heat pump grants in 2026: what’s still open.

Plenty of pages still talk about programs that have closed. Here’s where things stand as of September 22, 2026, your timeline all the way to the cheque, and the eight conditions to check off.

LogisVert, the main program
The broadest, and the only one still open
  • Who: owners of an eligible home in Québec: houses, plexes, condos with ducts, residential buildings.
  • Why: a central or multi-zone air-source heat pump, to use less electricity.
  • How much: based on the certified capacity at -8 °C and the certification, not on floor area or the quality of the ducts.
  • Conditions: unit bought in Québec, ENERGY STAR certified, installed by an RBQ-licensed contractor.
It’s the program that covers most of the central units AirGreen installs. Since 2025, federal grants are no longer available for these systems.
