Daikin Heat Pump and Air Conditioner Repair in Greater Montreal

Is your Daikin unit no longer heating, no longer cooling, or showing an error code? Our technicians come to you in Montreal, Laval, Longueuil, the North Shore and the South Shore to find the fault and get your system running again.

The Daikin Units We Work On

  • Daikin makes a wide range of heating and cooling equipment, from ductless wall-mounted heat pumps to central systems. Like any mechanical equipment, these units eventually need a repair, whether from normal wear or an unexpected breakdown.

    At AirGreen, we repair and maintain units of every brand, including Daikin. Our qualified technicians have the equipment needed to find the cause of the breakdown and recommend the right repair.

    What We Repair

    • Daikin wall-mounted heat pumps
      Water leak, error code, unstable temperature: we find the cause and fix it.
    • Daikin central heat pumps and air conditioners
      Weak airflow, a compressor that will not start, short cycling: we check the outdoor unit, the indoor unit and the controls.
    • Daikin multi-zone heat pumps
      A zone that no longer responds, a head that freezes or drips: we check every head and the refrigerant circuit.
    • Daikin commercial equipment
      VRV systems, rooftop units and other commercial systems: maintenance, diagnosis and repair for businesses and buildings.
  • Common Signs Your Daikin System Needs Repairs

    It’s essential to recognize the early signs of trouble to prevent a complete breakdown. Watch out for:

    • Unusual Noises
      Grinding, buzzing, or rattling sounds indicate mechanical or electrical problems.
    • Inconsistent Heating or Cooling
      Uneven indoor temperatures often signal underlying issues, such as blocked vents or thermostat malfunctions.
    • Visible Leaks or Excessive Moisture
      Any water pooling near your Daikin unit suggests drainage or refrigerant-related problems.
    • Increased Energy Bills
      A sudden spike in your energy consumption could indicate that your system isn’t operating efficiently.
    • Error Codes or Alerts
      Many Daikin systems are equipped to display codes for specific issues. Let us decode and address the problem for you.
