    Heating and air conditioning service in Montreal

    The same cooling system that stops the engine overheating in July is what feeds warm air to the cabin in January, so heating and cooling faults are often two symptoms of one problem. In a climate with this much seasonal range, both halves matter.

    What this covers

    • A/C Service
    • Radiator / Coolant
    • Heater Core
    • Thermostat

    Signs you may need this

    • Air conditioning blows warm, or cools much less than it used to
    • The heater blows cool air, or takes a long time to warm up
    • The temperature gauge reads higher than normal, or fluctuates
    • Sweet coolant smell, or visible coolant under the car
    • Windows fog up and are slow to clear

    How often it's needed

    There is no universal interval for A/C service; it is done when performance drops, since the refrigerant only depletes if there is a leak. Coolant is interval-based and varies by type — often somewhere between 4 and 8 years. A cooling-system pressure test before summer catches leaks before they cause an overheat.

    Quebec context

    A working defroster is a safety system here, not a comfort feature — and it depends on both the heater and the A/C, since air conditioning is what dries the air. Freeze-thaw cycles are also hard on hoses and plastic coolant fittings, which is worth checking in the spring.

    What affects the cost

    • Whether the fault is a simple recharge or a leaking component
    • Which part has failed — a thermostat and a heater core are very different jobs
    • How much of the dash must come apart to reach the component
    • Refrigerant type, which differs between older and newer vehicles
