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.
Air conditioning repair in Milano: where we operate
In Milan we work across a dense, vertical city: office buildings and large apartment blocks, renovated ringhiera houses in the historic districts, new towers and residential complexes in Isola, Bicocca and the Portello area. Here timing and access matter — Area C, inner courtyards, concierge desks, central systems in big blocks — and your request is routed to the nearest technician between the city and the hinterland, where traffic weighs most on timing.
Districts and areas of Milano: Centro · Brera · Navigli · Porta Romana · Isola · Città Studi · Lambrate · Bicocca · Bovisa · Niguarda · Baggio · Corvetto · Barona · Quarto Oggiaro · Lorenteggio.
And in the surrounding towns: Sesto San Giovanni · Cinisello Balsamo · Rho · Cologno Monzese · Segrate · San Donato Milanese · Rozzano · Corsico · Bollate and other nearby areas.

FAQ — Air conditioning repair in Milano
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.
How soon does the technician arrive?
Your request goes straight to the nearest available technician: in most cases it is picked up within a few minutes, with the visit the same day or by appointment.
Do you cover the Milan hinterland too, not just the city?
Yes. Beyond the Milan districts — from the centre to Bicocca, Lambrate, Baggio and Corvetto — we work in the first-ring towns such as Sesto San Giovanni, Cinisello Balsamo, Rho, Segrate and San Donato. Give the address and we put you in touch with the local technician.
How do call-outs in Area C or in buildings with a concierge work?
The technician agrees access and timing taking the ZTL/Area C and the building rules into account. If the job is on a central system it helps to flag it straight away, so the person who arrives is equipped for that kind of fault.
