Pro-Installer Tip
The Technical Friction: In a dual fuel configuration with a 21"-wide furnace and upflow/downflow coil, the EEV communication wiring between the GZV6SA4210 outdoor unit and the indoor coil must route through or alongside the furnace cabinet. Misrouted low-voltage wiring near the gas valve solenoid can introduce EMI noise on the communicating bus, causing intermittent fault codes (especially E7 or E8 communication errors) that only appear under heating load.
The Long-Term Prevention: Secure all low-voltage communicating wires at least 2 inches from any high-voltage or gas valve wiring inside the furnace cabinet, using adhesive-backed cable clips rated for plenum spaces. After commissioning, run the system through a full heating-to-cooling switchover cycle while monitoring the CoolCloud™ app for communication stability. This 10-minute validation prevents nuisance service calls 6-12 months post-install when temperature extremes trigger frequent mode changes.
The Expert Validation: Use the CoolCloud™ phone application to verify the communicating bus is reading all indoor and outdoor sensor values without dropouts. Confirm subcooling of 8±1°F at the outdoor unit service valve with a calibrated digital manifold gauge set (e.g., Testo 557s or Fieldpiece SMAN4).
The Professional Standard: R-32 refrigerant is classified as A2L (mildly flammable) under ASHRAE 34. All joints must be leak-tested per EPA Section 608 requirements using an electronic leak detector rated for A2L refrigerants. Verify local jurisdiction has adopted the 2024 UMC/IMC codes that include A2L provisions before proceeding with installation.
Key Benefits
- Dual Fuel Efficiency: Automatic switchover between 17.0 SEER2 heat pump operation and 97% AFUE gas heating delivers the lowest operating cost across all climate conditions, selecting whichever fuel source is most economical at any given outdoor temperature.
- Variable-Speed Comfort: The inverter-driven compressor modulates capacity from approximately 40% to 100% (and boost mode beyond rated capacity), maintaining tighter temperature control (±0.5°F) while reducing compressor cycling, duct noise, and humidity fluctuations.
- R-32 Environmental Advantage: R-32 refrigerant carries a Global Warming Potential (GWP) of 675—approximately 68% lower than R-410A (GWP 2,088). Combined with the higher system efficiency, total equivalent warming impact is substantially reduced over the system's service life.
- EEV Precision Metering: The Electronic Expansion Valve adjusts superheat in real time based on load conditions, replacing traditional fixed-orifice or TXV metering with fully variable refrigerant flow control for improved seasonal performance and dehumidification.
- Quiet Operation: Quiet-mode capability reduces outdoor unit sound levels to as low as 45 dBA through variable fan speed and compressor speed management—equivalent to a quiet residential conversation. Three selectable sound levels accommodate noise-sensitive installations.
- Future-Ready Platform: Communicating architecture supports two-wire connection between indoor and outdoor equipment, simplifying wiring while enabling advanced diagnostics, automatic setup, and firmware-upgradable control logic via CoolCloud™ Bluetooth diagnostics.

Let customers speak for us
I absolutely love how easy it is to use and how well they fit and look. Awesome!!
Excellent. Placed unit in a two room cabin with each inside unit on the same common wall. Outside temps were in the low 40’s and the cabin was quickly warmed.
Very easy to install, and with a little trouble shooting with help from tech. it was very quietly putting out ice cold air... Had a bad fuse in my disconnect....
This is a good air conditioner for the price. Our apartment living room and kitchen have been kept nice and cool. The complex we moved into actually already had these installed but I have been so happy with the performance I purchased one for my mom who lives in a tiny home, I'm an HVAC tech and it was about time to replace her HVAC. Yes, I recommend this.
We have zero regrets! No wait, one. That we didn’t get them sooner! We (my husband, self and 19yr old son) work outside noon-8am several days a week in Texas. It doesn’t matter how low you set your AC unit it’s just never enough and it just runs it into the ground. We finally decided to pull the plug. In my 40 years I’ve never slept so good. It’s like hotel good but in your own bed!!! Install was super easy because I watched him do it, LOL. I kid. I’ll ask for his install input and update but seriously he installed all 4 (3 bedrooms and 1 living room) in 2 days. Probably wouldn’t have taken so long if he didn’t have to pour a pad for them but it was well worth it! Last pic is from the Nest. They were installed Friday. Compare usage from Sat & Sun to before we got them! Insane!!!
This was best investment I've ever made. I put this on the wall on my porch that I've converted to a sun room. This extra space that I enclosed with plexiglass and wood and sealed with insulation stayed about 20 degrees different from out side. With a window unit and heaters. Now with the split unit it stays what ever temp I want it to be. The della split unit is so quite I have to put my ear on it to hear it run sometimes the out side unit is even quite. If you mount on outside wall that is a little thin and only a few inches thick it might give a little bit of a hum but so slight you have to want to hear it. Turbo cool or heat will cool or heat super fast. The system is perfect 👌 👍 🥰. I love it.
I live in Florida and our summers are brutal. I installed this in my garage.
It wasn’t a hard install but it took my dad and I about 8 hours. He ran the electrical.
Around this time of the year, my garage is around 82 degrees and +70% humidity, the air is very wet.
This morning it was 74” and 52% humidity.
The indoor and outdoor units are remarkably quieter compared to our house’s HVAC system.
I bought and installed 2 of the della mini splits in the last 8 months, one for my double wide 1800 sqf that I am remodeling little by little, and another for my daughters craftsman home. What an improvement! So silent! So efficient! So easy of operating. For the last 10+ years, we have been using windows AC units and radiant heaters after our central heat and air system broke. The suffering is over. We are saving $100 a month on the power bill and enjoying ourselves inside now. Our Great Pyrenees friends are enjoying the AC's too during the scorching hot summer days. They are pretty easy to install. Follow the instructions on the book and watch some videos on YouTube. On the second install, I made an electrical mistake and purchased the wrong breaker. I am only a landscaper by the way. No problem! I called the technical support number and a very nice tech called me back after just a few hours and figured it out by phone within 5 minutes. It is all great! We just keep it simple by using the remotes. I love the delay timer option. Now that the weather is cooling down (80's max), I set the timer so it doesn't come ON automatically before 12 pm. By the time the girls come from school, 75°f is back as set. GREAT PRODUCT, GREAT TECHNICAL SUPPORT
Installation was a breeze. Unit is working flawlessly. I love that it connected to my Alexa and I can voice control or use the Della app. I am going to purchase a second Della for our guest home.
Got these panels for my backyard as the wall for the Composting area. Black is good for absorbing the heat of the sun and is easy to hide the ugly things. It is a good quality product. The foot support is stainless steel and long enough to bind the ground and the panels. As it is with a good quality, it is just a little heavy, which may require two people to move around or install it.
Solid plastic material. Assembly was easy with a power screwdriver. Looks better than an ugly air conditioner unit.
Great value and just the right size. Note that if you want to place them in a straight line, you will need to use an electric screwdriver to tighten the screws.
Made from good quality materials. Very easy to install and assemble. Looks great to hide the trash bins. Would buy more for AC.
I use it to cover the trash can. It is very practical. This way you can't see the dirty surface of the trash can. I strongly recommend it.
Great product. Installation was very easy
