LG Mini-Split, Duct-Free Air Conditioning Installation & Warranty Info 


We recommend the installation of all LG Ductless Split Systems to be done by a licensed, trained & qualified HVAC technician with the proper knowledge and background. A trained technician will be able to judge the best location for the air handling (evaporator) unit and also the correct size for the area it has to cool. 


 Should you experience an issue during the installation or the initial startup of the unit please do not contact the manufacturer. You should have the technician that installed the units contact us or the manufacturer. LG cannot accept any service or warranty calls from anybody but a licensed HVAC technician. 


 Neither we or LG Electronics U.S.A. can be held liable for improper installation and operation of any LG air conditioning product purchased from our company. Should a warranty issue arise where parts will need to be replaced, an installation receipt will be required along with your sales receipt. Failure to provide a receipt or invoice may result in the warranty not being honored. 


Note: Warranties on mini split air conditioners only include parts and do not include labor. The licensed HVAC Technician who installs your air conditioner should always provide you with a labor warranty (preferably for a full year to complement the manufacturers' parts warranty).

Quiet and powerful

So far I have only used this indoor/outdoor package in cooling mode, and it has been fantastic. The moisture removal capability is impressive, especially during the first few hours of operation as the temperature in the house is brought down. Once the load is relieved, the VRF compressor slows down and delivers enough cool air to match the sensible load. The outdoor unit is very quiet and does not rattle.

Better than expected

Installed in my 24x28 garage. The space is 672 sq ft with vaulted ceiling (structural ridge, so it's open all the way to the top). 1/2 of the space has a loft. I installed the indoor unit about 10' off of the floor in the center of the 24' wall. This setup is super quiet, and there's no doubt in my mind that it could work in an even larger space. I shopped around, and you won't find a better price than this. My HVAC guy that did the install commented on the quality of the unit, and also the value. Free freight shipping, and the freight company was easy to deal with. I received everything i ordered within about 3-4 days.
