Installing a heat pump in a condo in Quebec: A complete guide 2026
Reading time: 8 minutes
Do you live in a condo and want to install a heat pump? It's entirely possible, but there are a few extra steps compared to a single-family home. This guide covers everything condo owners need to know.
Yes, it is possible to install a heat pump in a condo
More and more condo owners in Quebec are installing wall-mounted heat pumps. The advantages are the same as in a house:
- Savings of 40-60% on heating
- Air conditioning included (no more noisy window air conditioner)
- Individual temperature control
- Better comfort year-round
The main challenge: finding where to place the outdoor unit and obtaining the necessary approvals.
Step 1: Check your condominium declaration
First and foremost, consult your condominium declaration and building regulations . Look for the sections concerning:
- Modifications to common areas (balconies, exterior walls)
- Mechanical installations (air conditioning, heating)
- Rules about noise
- The exterior aesthetics of the building
What you might find
- Authorization required: Most condos require approval from the condo association.
- Designated locations: Some buildings have designated areas for outdoor units
- Prohibitions: Rarely, but some condos prohibit visible outdoor units
- Aesthetic requirements: A specific unit cover or color may sometimes be required.
Step 2: Obtain union approval
How to submit your application
Prepare a complete application to maximize your chances of approval:
- Letter of application explaining your project
- Technical specifications of the heat pump (dimensions, weight, noise level)
- Photo or diagram of the proposed location
- Noise level (Kanartic units are at 40 dB — quieter than a refrigerator)
- Installation method (DIY or professional)
Arguments in favor of your request
- Reduced electricity consumption (good for the building)
- Removal of the window air conditioner (more aesthetically pleasing)
- Very low noise level of modern heat pumps
- Increase in the value of your unit
- Many similar condos have already approved this type of installation.
Typical time
Allow 2 to 8 weeks for a response, depending on the frequency of board meetings.
Step 3: Choose the location for the outdoor unit
Option 1: Balcony
Benefits :
- Private area, easier to approve
- Easy access for maintenance
- Simple installation
Considerations:
- The balcony must be open (not glazed) for air circulation.
- Check the load capacity of the balcony (the unit weighs 30-50 kg)
- Plan for the drainage of condensation/defrost water.
- Keep a minimum clearance around the unit
⚠️ Glazed/enclosed balcony: Does not work! The outdoor unit needs fresh air. An enclosed balcony would cause overheating.
Option 2: Exterior wall (wall bracket)
Benefits :
- Does not take up space on the balcony
- Good air circulation
- Often less visible
Considerations:
- Generally considered a common part = approval required
- More complex installation (robust wall mount)
- Check the wall structure
Option 3: Flat roof (some buildings)
Benefits :
- Out of sight
- No impact on the balcony
Considerations:
- Longer refrigerated lines (choose 25 feet)
- Roof access required
- Coordination with the union
Recommended capacity for condos
| Condo type | Area | Recommended BTUs |
|---|---|---|
| Studio / 1½ | 400 - 550 sq ft | 9,000 BTU |
| 3½ (1 bedroom) | 550 - 750 sq ft | 9,000 - 12,000 BTU |
| 4½ (2 bedrooms) | 750 - 1,000 sq ft | 12,000 - 18,000 BTU |
| 5½ (3 bedrooms) | 1,000 - 1,300 sq ft | 18,000 - 24,000 BTU |
| Large condo / Penthouse | 1,300+ sq ft | Multi-zone |
Note: Condos are often well insulated and have less surface area exposed to the cold (neighbors on both sides). You can usually choose the lower end of the price range.
DIY installation in a condo: Is it possible?
Yes, in most cases. DIY installation works just as well in condos as in houses.
Advantages of DIY in a condo
- Savings of $1,500 to $2,500 on installation
- No need to coordinate with a contractor
- You control the timing
Specific considerations
- Noise: Use a drill during reasonable hours
- Dust: Drilling into the wall will generate dust — arrange for someone to be outside to collect it.
- Access: If the outdoor unit is on the balcony of the neighbor below, coordinate
- Electricity: Check that your panel can handle the load
When should you call in a professional?
- Installation on an outdoor wall bracket at height
- Rooftop installation
- If the union demands it
- If you are not comfortable with DIY
Electricity in a condo
Check your electrical panel
Condos often have 100A or 125A electrical panels. Check:
- Is there room for a new circuit breaker?
- Do you have a 240V circuit available (for the 18000+ BTU)?
Requirements per model
| Model | Voltage | Circuit breaker |
|---|---|---|
| 9,000 BTU | 115V or 230V | 15-20A |
| 12,000 BTU | 115V or 230V | 15-20A |
| 18,000 BTU | 230V | 20-30A |
| 24,000 BTU | 230V | 30A |
Tip: If you're unsure, consult an electrician about this. It usually costs $150-$300 to add a dedicated circuit.
Noise management in co-owned properties
Noise is often the main concern of unions and neighbors.
The real figures
- Kanartic heat pump: ~40 dB (outdoor unit)
- Refrigerator: 40-45 dB
- Normal conversation: 60 dB
- Window air conditioner: 50-60 dB
In practice: A modern heat pump is quieter than a window air conditioner. That's a selling point for your building management!
Tips for minimizing noise
- Install on anti-vibration pads
- Avoid placing the unit against a shared wall with a neighbor
- If possible, direct the fan towards the outside of the building.
Typical costs for a condo
| Element | DIY | With professional installation |
|---|---|---|
| 12000 BTU Heat Pump | $2,450 | $2,150 (standard) |
| Facility | $0 | $1,500 - $2,500 |
| Electrical circuit (if necessary) | $150 - $300 | $150 - $300 |
| Support/accessories | $0 - $150 | $0 - $150 |
| TOTAL | $2,600 - $2,900 | $4,000 - $5,100 |
Condo FAQs
Can my union refuse my request?
Yes, but it's rare if your application is well-presented. Valid reasons for refusal include: restrictions in the declaration of co-ownership, significant aesthetic impact, or structural problems. A simple "no" without justification can be challenged.
Can I install it on a glass-enclosed balcony?
No. The outdoor unit needs fresh air to operate. An enclosed balcony would cause overheating and malfunctions.
Will my downstairs neighbor be bothered by the running water?
Condensation and defrost water must be managed. Install a collection tray or a drain pipe directed to a suitable location.
Will the outdoor unit freeze on my balcony in winter?
Frost is normal and is automatically defrosted. Just make sure the meltwater can drain.
Do I need to inform my immediate neighbors?
It's not mandatory, but it's courteous. Explain that the unit is quiet (quieter than a window air conditioner) and that you will be attentive to any inconvenience.
