Della 3 Zone 28000 BTU/h, 20 SEER2, 208-230V, ETL Listed, AHRI Certified pre-charged air conditioner unit.This air conditioner is designed with several smart functions: multiple fan speeds, sleep mode, heating, cooling, dehumidifying, dry modes, 4D air flow(up-down left-right), energy saving mode.
  • MULTIPLE ROOMS: Enjoy individual temperature controls in each room for climate control. Comes with 3 indoor air handlers 9000 BTU + 9000 BTU + 18000 BTU with separate controller for individual rooms and 1 outdoor condenser. Maximum Fuse Size is 30A. 3 pcs 6.56ft outlet drain pipe (inner/outer diameter size:15.5mm/16.9mm), 3 pcs 16ft copper pipes lineset (Standard size 1/4" & 3/8" outer dimension) and 3 installation kits included
  • MULTI ZONE CAPACITY: This configuration is designed for spaces where not all indoor units are expected to operate at full power at the same time. If the total indoor capacity is higher than the outdoor unit's output, the system can still function properly, but cooling or heating performance may be slower when all zones are operating beyond capacity. For consistently high demand across all zones, a larger or multi-system setup is recommended
  • QUIET OPERATION & INSTALLATION: This air conditioner is ultra silent at only 29 dBa. The unit provides equal airflow in every part of your room and can adjust to 60-90 degrees Fahrenheit to suit your comforts in just a few minutes. This system mandates professional installation, it's not a DIY mini split AC. Line-set vacuuming is required during installation. Any alteration of line-set length requires adjusting freon levels

  • Awesome units ! Awesome units !
Size: 3 Zone 28000 BTU 9+9+18
Well we saved money by buying these and doing it ourselves. My husband is a sprinkler fitter and has some construction knowledge. I have a 1000 square ft house and we put one in the basement, one in the living room and one in our bedroom. The window AC were killing us at 400+ electric bills and the house was uncomfortable and not that cool. The window AC if I cooked the house got hotter, but with this unit it was awesome. My bills went down and I was finally comfortable. I have boiler heat in this house and we tested the heat and they work great and if my boiler goes out I’m glad to have a back up. FYI they need a way to drain. I think the drain tubes provided are cheap and you can up grade that ... show more

  • You will need additional line
Size: 3 Zone 28000 BTU 9+9+18
It does come with everything but everything is short 16ft you’ll find out isn’t enough and you’ll end up having to get longer lines and cables. Our house is only 1200sqft and the wires are just not long enough at all to reach the condenser.

  • DIY your own HVAC!
Size: 3 Zone 28000 BTU 9+9+18
My central heat pump failed and would have costed me $18,000 for a replacement through a company. Thats alot of money most people don't have including myself. So I decided to take the DIY route and install this unit in my 1800 sq ft house and it was the best decision I could have made. This thing is so much more efficient than my old central unit and zoned temps make all rooms feel exactly how you want. Even on the turbo setting the fan is whisper quiet. Only downside so far is the lack of a fully functional mobile app. Do your research and watch some tutorials and you'll find that this unit is more than worth it. ... show more
