DO NOT BUY. I had problems with this since the beginning: they replace the complete equipment, than 4 months latter they replaced the fan. After 5 months of the repair, it's turning on and off by itself. it was SIX MONTHS AGO, and they COULD NOT FIX IT, they went to my house THREE TIMES, with the WRONG spare part... and until now, ITS NOT FIXED. The worst after sales, rude, not helpful, you call then asking for an update, and they never know when it will take place, only give excuses for not repairing it, they schedule the day for the technician without consulting and it's IMPOSSIBLE to change in their terrible website... And they do not offer me an option for that, it's always that I need to wait.
