Dolphins,
Also had a leaking a/c. Euronics came straight out and sorted it. Thankfully it was only a build up of ice melting. They have seen many instances of blocked, broken and not even installed drainage pipes. They will no longer fit units in the Penthouses, except top floor, due to the drainage pipe problems. 0034 868 181 121. They also checked out my other a/c units for free.
Good luck.
