The faults we repair

Tell us what the unit is doing (or not doing): wall-mounted AC, multi-split or heat pump, we track down the cause.

  1. 01

    No longer cools

    The unit runs but blows lukewarm air: clogged filter, low refrigerant, a faulty sensor or compressor.

  2. 02

    No longer heats

    Your heat pump or reversible AC no longer produces heat, or locks out in cold weather.

  3. 03

    Water leaking from the indoor unit

    Blocked condensate drain, full pan or the wrong slope: water runs down the wall.

  4. 04

    Bad smell

    A musty smell when it starts: the heat exchanger and drain pan need cleaning and disinfecting.

  5. 05

    Unusual noise

    Knocking, vibrations or whistling, from the indoor unit or the outdoor unit.

  6. 06

    Error code or flashing light

    The code shown points the diagnosis in the right direction: note it down before calling us.

  7. 07

    Ice on the unit or the pipes

    Abnormal icing often signals a problem with the airflow or the refrigerant.

  8. 08

    The unit won't start

    Remote control, power supply, circuit board: we find the exact cause.

Good to know

Before you call: 4 quick checks

Remote control: check the batteries and the selected mode (cool, heat, dehumidify, fan).

Circuit breaker: make sure the air conditioning breaker hasn't tripped in your fuse box. If it trips again, don't keep resetting it.

Filters: dust-clogged filters are enough to make performance drop. Dust them if they are accessible.

Outdoor unit: nothing should block the airflow (cover, leaves, furniture). Still not working? Switch the unit off and call us.

Making the right choice

Repair or replace your unit?

On a recent installation, repairing is almost always the right choice. On an old unit with more and more breakdowns, we give you an honest opinion: repair, or consider a new installation.

Either way, a yearly service is still the best way to avoid a breakdown in the middle of a heatwave or the depths of winter.

    Intervention très rapide un vendredi soir et un jour férié pour une fuite urgente sur notre chaudière. Le technicien a identifié le problème et est revenu le lendemain pour remplacer la pièce et tout remettre en service. Service efficace et réactif dans une situation d'urgence.
