    • Mini split unit

    • Wonderful company to deal with
Size: Dual Zone(2) 20000 BTU 9+9
This is my second set of mini-splits in a barndominium I've lived in since 2010. Although I'd never heard of the brand, I read positive reviews and purchased a dual unit this spring and had a local HVAC company install them. They've worked great for a few months until an E4 error occured which indicated low pressure. The installer came back and found a loose fitting he missed. The best thing about these are the people at Della. I can't tell you how responsive and dedicated they are to customer service which is unfortunatley rare these days. They respond quickly and offer suggestions for troubleshooting. If you're considering these, rest assured, you'll be pleased! ... show more

    • Window unit = trash. Mini split = gold.
Size: Dual Zone(2) 20000 BTU 9+9
Took about 2 weeks to arrive in a tractor trailer. Not a problem for me as I unloaded with my forklift. The condensing unit has a dent on the side. It's just cosmetic. I emailed the seller and agreed to a $180.00 refund. The evaporator look good and after drilling a hole through the wall and attaching the mounting bracket went right on no problems. The kit comes with a plastic tube to use through your hole but I found it to be cheesy and flimsy so I didn't use it. The lineset,drain,and electrical wires were fine. The copper tube is extremely thin walled and easy to bend or form using just your hands. I did buy the mr.cool lineset covers which I believe look the best even though they are pricey. They come with the fittings covers and elbows needed to make the install look pro. I shortened one lineset a few feet and lengthened the other lineset a few feet. Easy to do using some flare unions. I ran about 20 feet of 12/2 Romex wire from my electrical panel with a double pole 30a breaker for the 220v supply. On the outside I mounted a 60a non fused disconnect and a couple feet of carflex to tie it in. Used my vacuum pump and gauge set to get it down to 500 microns before opening the valves and turning it on. Been running these 2 heads everyday now as it's been a really hot summer this year and they work great. Dead silent operation too both inside and out. I will definitely be back to buy another one again next year. ... show more

    • This is a Vegas gamble move and we lost!
Size: Dual Zone(2) 20000 BTU 9+9
Thought I was getting an excellent price for the unit. After installing, have 3 error codes and the units will not heat. Have called Della 3 times first was hung up on after explaining to the customer service rep that I couldn't find a single HVAC technician in CT who was willing to work on it (had 3 cancellations after they found out the brand), call number 2, husband was told someone would email him a list of technicians in the area-that was 3 days ago, called again, was told a technician would call me back, nothing. We are pretty polite and patient on the phone. Do not buy Della products as there is zero support or help if anything goes wrong. The units we have are lovely, quiet, and not functional. So now I have lovely white vinyl wall art until I figure out how to return them. ... show more

Size: Dual Zone(2) 20000 BTU 9+12
This item saved us money! We were quoted by quite a few professionals who wanted triple this amount. The unit doesn't take up much room on the wall. Easy installation. My husband was able to get it installed in a day with no issues. The quality is better than I imagined. I have not noticed any leakage so far. It is a sleek white look. ... show more

This is a dual zone mini split. When vacuuming, there is not a master port. And the “A” and “B” lines are isolated from each other, so you can vacuum one line at a time. I found this out because I had two vacuums hooked up, one to each line, and after verifying the vacuum was holding successfully, allowed a small amount of refrigerant into the “B” line and only the gauge on “B” line instantly went to positive pressure… the “A” line was still holding the vacuum. The condenser oem packaging doesn't protect the sides, so when UPS dropped the package out the truck on its side from 3’ high it suffered several dents, but thankfully still ended up working perfectly. ... show more
