Horror. This is the word that can be defined by this company.
We purchased a multi-air conditioner from Elco three years ago after half a year the technician who arrived did not cool down and convinced the air conditioners we were convinced. Unfortunately every few months we hire a technician, either the air conditioner does not cool (in summer) or it does not heat (in winter) all the technicians have been with us none of them find the problem (make claims underground) and for them there is no problem at all. Air conditioner on 17 temperature power with the highest air intensity, in a room 25 degrees and "no problem" .. Do not approach under any circumstances.
