AC unit not cooling, leaking water or showing an error code? Our refrigeration technicians come to your home to diagnose and repair single and multi-split air conditioners of every brand: gas recharge, circuit board replacement, cleaning and sanitising, communication errors.
When to call us
- Not cooling, or cooling poorly (possibly low on refrigerant gas)
- Water leaking from the indoor split unit
- Error code on the display (e.g. E07, U4, F3)
- Unusual noises from the outdoor unit
- Bad smells: filters need cleaning and sanitising
AC gas recharge
If your air conditioner no longer cools like it used to, the most common cause is a drop in refrigerant gas (R32 or R410A). The technician measures the circuit pressure, checks there are no leaks — recharging too often is a sign of a leak that needs fixing — and recharges the gas with certified equipment, bringing the system back to its original performance.
AC cleaning and sanitising
Dirty filters and heat-exchange coils mean bad smells, allergens in the air and higher running costs. A professional split-unit clean with sanitising at the start of the season removes mould and bacteria from the air circuit and restores efficiency: the ideal service before summer, and we can do several units in the same visit.
Electronic fault and board repair
Is your AC flashing or showing an error code on the display? The cause is usually a temperature sensor, a fan motor or an inverter board. The technician reads the code, diagnoses it on site and replaces only the faulty part: in most cases the repair costs a fraction of a new system.

Frequently asked questions
How much does it cost to recharge the gas in an AC unit?
It depends on the type and amount of gas: roughly 80 to 150 euros. If it needs recharging often, there is a leak that must be found and repaired.
My AC shows an error: should I repair it or replace it?
The technician diagnoses it on site: often the problem is a board or a sensor that can be replaced for a fraction of the cost of a new system. If a repair is not worth it, you get a transparent quote for replacement.
Do you work on all brands?
Yes: Daikin, Mitsubishi, Samsung, LG, Haier, Hisense and all the main brands on the market.
