I purchased a Daikin System, at first I was skeptical with being it's a brand I never heard of- The Installing ac company assured Daikin is the best and he backs the brand with a Peace if mind warranty – 12 yr warranty- 12 yr labor insurance not offered by other Brands -he even helped navigate to actual online websites and showed me the real reviews – showed me the savings and comfort the ac will bring into our lives – well it's been 7 months and the Daikin system is outstanding, it runs efficiently and very quiet – my electric Bill even dropped – my neighbor wants one now and he is going with the new fit – I highly recommend and they are made in the USA

I purchased this AC after it was offered by a local contractor this summer. Works great, quiet, and low utility bill. Never heard of Daikin but I am glad I purchased the unit so far.

The variable drive DX20VC is an excellent choice for the homeowner that plans to stay in their existing home for 5+ years. This pay back on savings from utilities, comfort, and lack of noise that this unit provides is second to none. We have installed many of this exact model and I can honestly say that we have not been back to one installation for anything. The warranty is the best in the business and the factory support has been great. Nice product Daikin!

We installed 4 of these systems at the same home, which was of course a costly investment for the homeowner so they were a little nervous about such a purchase. After a summer the customer is so happy with the performance and has reported unbelievable energy savings. The outside units sit just outside the master bedroom and they are relieved to be able to sleep well again! Also, as our installers and service technicians learn more about this product they've really enjoyed the ease of installation and testing.
