It's An Air Conditioner With Heat!

The ac works just fine and I like the fact that it cycles and both the cold and the heat work. It is being used in a small room for the time being and the temp is set to 74 and it seems to be keeping that temp with no problem. It's a little louder than I would like, but it works and that is what counts. One thing that I want to mention. When I installed it and started using it a smell came out of it like it had been in storage for some time. It was an old type smell. Filled the room. I had to use frebreeze to knock it out and I ended up spraying the coils on the ac to help knock out that smell. It seems to have worked. No more smell.

Worth the money

This was bought for my son's room that I added on. He has used this unit now for a couple of weeks. It has had no problem cooling 230sf. I haven't been able to tell much of a change in my electric bill since using this as well. Seems to be very energy efficient. I will update review when we use the heat. So far it has been worth the purchase.

Ac unit

Finally up and running. I wasn't aware that it was a 220. I had to have a 220 plug installed before I was able to use it. Cools my large room very well. Love that's it's both air and heat.
