Their 24 customer service is not true. I had my unit serviced with them and it was covered under a warranty..the ac stopped working at 9:30 at night. I called them and was assured that I would hear back from a technician that night. Next morning at 10:00 when I called back to find out what had happened their answering service said he couldn't find the technician in a very rude way. After not figuring out the problem the first 3 times they want to charge me a $150 travel charge again! That's over $300 spent with them and our AC is still not working. I would never use them again.
