I bought a 3 zone cassette style minisplit system from Della. Install was simple for a GC. I had one issue with the instructions and ran into a mistake that needed a special fix and customer service was exceptional in resolving it for me. And of all the knock off minisplit brands out there. I fully recommend going with DELLA, rather than saving that 3% difference. Della actually lasts.

Generally a great setup. This unit works great. Cons: short one item in the line cover kit. The wiring harness from compressor to inside unit was about one foot short for the freon tube length. 9k unit.

I purchased a della portable ac with heat. It was delivered by a 3rd party shipper who threw my unit from the truck onto my sidewalk. The unit was split up the side but still worked. Della actually sent me a whole new unit for free without requiring me to return the original. 3 years later and both units are doing well. Customer service that actually serves is hard to find but Della is where it is at!

Purchased the unit on July 2nd and the site asked me to select a delivery date. I picked July 7th. My son also ordered a unit on the same day with the same delivery date. When his unit showed up and mine didn't I called customer support. I navigated through the automated system and the customer service lady I eventually spoke to told me she would have to talk to a supervisor and will get back with me. I never heard from her but received an email that had a tracking number and carrier instructing me to contact them directly. When I called them, they had no record of the order and I wasn't in their system. I called Della back again and spoke to a guy that responded "This is a tough one". When I asked "what does that mean", he replied " I will need to track this down and get back with you. Never heard from him. Now when I call and get the same automated system, I just keeps telling me it cant understand me and please say that again over and over. My unit is still not here. I received a new email with a new tracking number and new carrier instructing me to call them. Was told by the carrier they weren't notified of the pick up until July 7th and they picked up the unit at 7 pm the same day. Now I have to delay my vacation because the unit will not be delivered until the 13th or 14th. If I had known how much time I wasted tracking this down, I would have bought another brand. The follow up emails by Della customer service could care less. They never tell me what happened or offer to correct the situation and only want to blame the carrier. Buyer beware...there are a lot of mini split brands out there, I would buy anyone but Della.

I recently had a problem with two of my della units losing connection. A phone call to Customer Service quickly solve my problem as agent. Hector knew his stuff and was able to get me reconnected quickly. He was very patient with me and walked me through each step. I normally don’t get such good knowledgeable Tech Support when I call for it nowadays.

I ordered two Mini-split systems, a DELLA Vario Series 28000 BTU Dual Zone and a DELLA Vario Series 28000 BTU Tri Zone. The ordering process was simple, the delivery was quick and the product thus far has worked very well. I cannot say enough about the customer service and quality of product.
