Boston Standard installed 3 LG high efficiency air conditioning units in my house in June and the results have been a disaster. Immediately after installation the kitchen unit had yellow water running down my wall. The bedroom unit makes a loud gurgling noise waking us constantly. Those noises continue to this day despite repeated service calls. Their people are polite and professional, but can’t seem to get any of the problems solved. The trouble I’ve had with my system is so aggravating I would never recommend it.
