Purchased minisplits and lineset covers for a home I'm renovating. I haven't run the minisplits yet but the installation was straight forward. I will say the lineset covers are top notch. Nice looking and easy assembly.

Ordered an Optima 12K system based on efficiency and reviews. The outdoor unit arrived with significant shipping damage. I contacted Della and they responded within a couple days offering a discount or full replacement. I'm very impressed with their prompt response and resolution. Once installed the unit is very impressive. In the bedroom it's almost silent. Very efficient as well. I would highly recommend.

So far my experience has been great with my Della four unit mini split system. I got a great deal ordering directly through their website, 10% off for new customer saved me over $300. Shipping was fast. Customer service has been very helpful during several calls to clarify installation guidelines. The unit was installed in a 130 year old house with no central HVAC. THIS UNIT COMPLETELY TRANSFORMED THE HOUSE!! The upstairs went from being unusable in the summertime to completely comfortable, easily maintaining 70° temperatures. Outdoor unit is so quiet, it's hard to tell when it's running or not. The app has worked flawlessly. I really have no complaints at this time. Longevity is the only pending question mark, but so far so good!
