For the money the linesets is pretty good. On the thinner thickness side, but the factory flares looked good.
Works as it should
Worked well
I love this so ixxy works with the all Della products.
I like your product easy to working with all parts And all products thank you that’s my first time install. I think I proud myself. I did a good job I think so.
I made the most common of mistakes and kinked my first line set. The second line set was delivered quickly and after inserting the line bending inserts that come with the DELLA install kit everything was perfect. Using a 10' line set allowed my install to be free of any excess line needing to be curly up and stored behind the unit. As always, everything from Della is top notch installs easy and hopefully will last a long time.
This is our second Della. This one was installed in our home. It was an easy process from start to finish. I worked with Brenda during the ordering. She was very patient and understood what I wanted. My biggest worry was drilling through my 10” wall. As it was a log home. After a trip to our local plumbing store I came home with a 2 1/2 bit and a 10 inch extension. I took my time with everything. As far as the installation the you tube videos made it pretty easy.
Great service, prompt shipping and excellent system installation and performance!
Went together well. Easy to use.
Received as scheduled. Thanks!

I added 5 splits to our rental property and it makes all the difference
I ordered both the 25ft and 16ft line set, quality is very good and has everything needed for install. Customer service from this company has been excellent! Will purchase again.
Worked exactly like it was supposed to
Quick, easy setup couldn't ask for anything more simple. Had a house full of people on the 4th July and it kept up with kids running in and out, and cooking.
Great customer service.
I built an addition to my house and wanted to leave the mini split in the same spot. I had to run my lines under my floor to reach the unit. The extension worked well.
Line set came well packaged. Made install easy.
Installation was easy and they provided clear instructions. The 24/7 support chat was extremely helpful. I did have an issue with the tool rental set but Della was responsive and helped get me where I needed to be quickly! Follow the install instructions and this DIY is an easy process.

Reasonable price and quality product. Quick shipping .
Could have found cheaper but wanted to maintain same brand name
The Line sets were shipped fast. I did how ever find after receiving them that they were not needed and they did have a 30 return policy when I called to return them I was told that I would have to pay return postage. I live in the most remote place in the lower 48 states and the return postage was a huge deal for me. The person on the line said there was nothing she could do about it but that they would buy them back if I was unhappy I would only get 1/2 of what i paid or they would give me 65.00 and I could sell them. I was very dissatisfied with this company. Sincerely Deb Bielby
On,right price ,excellent quality, and most important diy friendly and easy to install. Thanks to all that made ir possible BillMoody 7/20/25
