The most common faults
- The unit blows air but no longer cools, or no longer heats.
- Water is dripping from the indoor unit.
- An unusual noise: clicking, vibration, whistling.
- An unpleasant smell on start-up.
- An error code appears, or the unit switches itself off.
- The outdoor unit will not start.
Some causes are simple, such as a clogged filter or a blocked drain. Others involve the refrigerant circuit or the electronics and call for a proper diagnosis.
Understanding the fault before acting
On site, the air-conditioning technician first listens to what you have observed, then methodically checks the power supply, circuit boards, sensors and fans, as well as the circuit's pressures and temperatures. If a leak is suspected, they search for it and pinpoint it. Any handling of refrigerant is carried out by a technician holding the refrigerant handling certificate (attestation de capacité) and recorded on an intervention sheet.
A quote first, then the repair
Once the cause is identified, we explain the fault in plain terms and give you a quote. Nothing goes ahead without your agreement. Our principle: repair before replacing. A fan, a capacitor or a sensor can often be changed for a fraction of the price of a new unit.
If a repair is not reasonable (a very old unit, a part that cannot be found, a refrigerant no longer on the market), we tell you frankly. Our advice service then helps you choose a correctly sized replacement.
Requesting a call-out
For your home or your shop, describe the fault on the contact page: brand, type of unit, symptoms and, if possible, a photo of the rating plate. We reply within 48 working hours with a free quote, and the visit usually takes place within 24 to 72 hours depending on the season and area.
Worth knowing: many faults stem from a lack of servicing. Annual servicing prevents a good number of them.
