First of all the fireplace cabinet is beautiful! My kids bought it for me for Christmas last year and I've enjoyed the ambiance it gives but had never used the heater! My furnace quit working so I turned on the heat feature but it didn't work. Called customer service and although it's just outside the 1 year warranty, they honored the warranty anyway and are sending me a new insert!! Now THAT'S what good customer service looks like! Would highly recommend this company!

So far so good with the Serena Della mini split. Was able to speak with customer service and Tech Support. It was shipped quickly, has app controls. Can also use remote as a temp sensor.

Ordered a 2 zone mini split. Paid for 2 line sets. Only received one. Paid for a 30 amp disconnect that didn’t receive either. Luckily my hvac installers had everything they needed on the truck. Not sure how you don’t check shipping better

RE: Tower Fan Not Working. Someone answered the phone on my first call. Joey was very helpful and explained how to get a fan replacement at no extra charge. I did call one more time just to check on the status of my fan and again, Joey was extremely helpful and everything was being processed & my fan was on its way. I would absolutely use this company again for their products!

I have so far ordered 2 units and a put to order a third one, I have a somewhatmediumsize property with additionalbuildings, they have worked flawlessly for AC and Heating. Installation was easy and straightforward, I did asked my electrician friend to do the wiring, since I have no experience with electricity.
