Bests & Worsts Reviews from Amazon

This is a really nice set up! The indoor unit is charged with nitrogen for shipping so removing the caps is fine. The only specialty tools youll need are gauges and a vacuum pump. The sellers had prompt and great advice. The unit is precharged for a 25 foot lineset according to the seller although the installation manual recommends adding 1lb additional r410a (for lineset >20ft) but Ill believe what Im told. I havent started the system yet so a follow up review is pending. The only other slight concern is that the manual calls for copper conductor from the outdoor unit to the indoor unit but the cable that came with it is 16awg aluminum conductor. I doubt there will be a measurable voltage drop over 15 feet but its not what the manual calls for. Im VERY happy with the finished product. UPDATE: I have emailed HighSEER numerous times with various questions about this unit and EVERY TIME they're prompt and accurate and helpful. The customer service has just been fantastic. If you could imagine what customer service SHOULD be like, HighSEER has fulfilled the expectation. I cant thank you enough for your helpful service. About the unit: Quiet. Quiet quiet!! The outdoor unit is on the back patio and its so quiet that a whisper conversation can be had while its running. The indoor unit is inaudible. Our 1100 sqft house is comfortable with thermostat set to 75 and its 87 outside. Latest update: After installation, the indoor unit started up and a bunch of blue plastic pieces fell out of the indoor unit. I emailed HighSEER (the seller) and asked them what they thought of it. After one day, they responded and diagnosed that the blower cage must have gotten broken (which I couldnt determine from my preinstalled inspection) They immediately sent me a NEW blower cage FREE of charge!!!! So, the product is nice and Im HAPPY with it but the CUSTOMER SERVICE from HighSEER is absolutely the best customer service that I have experienced in ANY industry!!!!!
