Heating questions
Not a review, but questions that I can't seem to find the answers to online.
-- When used for heating, at what outside temperature does the unit stop providing heating and must be shut off?
-- When used for heating, at what outside temperature does the unit become less efficient?
-- What is the HSPF rating?

Super cold
Installation was a breeze. The output is fabulous. We only run it on fan speed low. It cools our florida room and camper with no problems. Perfect for Florida's hot summers.

I’ve had this two weeks now. Temperatures here in east Texas have been 105 to 109 each day. This unit under these adverse conditions has performed flawlessly. I’m impressed so far…. Hope this unit last a long time.

good features
Purchased recently to replace old unit. I am reasonable pleased with the unit features, but the unit is a little louder than expected.

Strong, powerful,quite!
Great cooling in a portable building (not so good insulation) in the West Texas sun! Amazingly quite! After much research I selected this LG unit and I’m sure glad I did. Loaded with features easy to install I am so far 100% satisfied.

Great buy
I love it. The E-saver function is great. Once I figured out that I could connect to the A/C by WiFi and got it setup, I love it even better. I have it in a sunroom that I don’t need it on all the time, it is great to be able to program it to come on and shut off.

Not so great
The AC unit was a nice size with great features like the Wi-Fi control from a phone app. It cooled and heated well for 11 months, then the AC froze up and leaked all over the floor. I contacted LG and they had no one to service the unit in the central Texas area… so they refunded the purchase price… after a month and hours on the phone with customers service.
