Our Expertise
Repairs You Can Rely On
At Allard & Emond, we provide trusted, efficient, and effective HVAC repair services for homeowners across Montreal and Laval. When your heating or cooling system stops working, our certified technicians are here to diagnose the issue accurately and restore your comfort as quickly as possible. You can count on clear communication, transparent pricing, and reliable repairs every time you call.
Most repair calls are booked for the same day or the next, because a furnace that quits in January or an air conditioner that fails in July is not something that can wait. We repair most major residential systems regardless of who installed it, and carry the parts for common brands, so most visits finish in one trip.

What We Repair
Systems We Repair
Our certified technicians provide HVAC repair services for all major residential systems across Montreal and Laval, including:
Heat Pump Repairs
Central and ductless heat pump repairs, from a unit that no longer heats or cools to error codes, ice build-up on the outdoor coil, and compressors that short cycle.
Furnace Repairs
Gas and electric furnace repairs, including a furnace that will not start, blows cold air, trips the breaker, or shuts down mid-cycle through a Montreal cold snap.
Air Conditioning Repairs
Central and ductless air conditioning repairs covering weak airflow, warm air from the vents, refrigerant leaks, frozen coils, and outdoor units that will not run.
Geothermal System Repairs
Geothermal repairs on the heat pump, circulating pumps, and loop field controls, so a system built to last decades keeps performing like one.
Air Exchanger Repairs
Air exchanger and HRV repairs for units that have stopped running, are noisy, or are leaving the house stuffy and the windows fogged.
Humidifier Repairs
Whole home humidifier repairs when the unit is not holding humidity, is leaking, or has stopped responding through Montreal’s dry winter months.
Thermostat Repairs
Thermostat repairs to ensure accurate temperature control and reliable communication with your HVAC system.
* Please Note: We do not provide repair services for oil furnaces due to provincial regulations. Quebec law restricts major repairs on oil furnaces, which means a furnace replacement may be your best option. Learn more about our furnace conversion services.
Common faults
Problems We Fix Most Often
Most calls we take start with a symptom rather than a diagnosis. If your system is doing one of these, it is worth booking a technician:
- The furnace runs but the house never reaches the set temperature
- The air conditioner blows warm air, or only cools some rooms
- The system turns on and off every few minutes
- A burning, musty, or electrical smell when the system starts
- Grinding, squealing, or banging from the indoor or outdoor unit
- Ice on the outdoor unit in heating season
- Water pooling near the indoor unit or furnace
- Energy bills climbing with no change in how you use the system
We serve Montreal, Laval, and the surrounding West Island and North Shore communities, including Pointe-Claire, Dollard-des-Ormeaux, Saint-Laurent, and Dorval.
Long-lasting repairs
Making Repairs Last
After completing a full diagnostic, our technicians present you with a recommendation alongside alternative options so you can make an informed decision. Once an option is selected, we prepare a transparent repair estimate so you know exactly what you are paying for.
Our technicians then complete the repair efficiently, taking the proper precautions to keep your system running reliably and prevent future breakdowns.
Where a repair is one of several sensible paths, we will tell you what a replacement would cost as well, so the decision is yours with both numbers in front of you.
