Pro-Installer Tip: Dual Fuel Changeover & Refrigerant Line Adaptation
The Technical Friction: The GZV9S heat pump uses ⅞" suction service valves but requires 1⅛" suction line sets — installers must supply ⅞" to 1⅛" adapters at the condenser. Additionally, dual fuel changeover point calibration requires verifying the outdoor thermostat lockout setting matches your climate zone's economic balance point (typically 30–35°F in most regions).
The Long-Term Prevention: Verify subcooling at the service valve targets 11±1°F and run a standing-pressure decay test at 300 PSI for a minimum of 30 minutes before releasing R-32 charge. This prevents nuisance low-pressure lockouts and compressor liquid-slugging callbacks during the first heating season when the system transitions between heat pump and gas furnace modes.
The Expert Validation: Use a digital manifold gauge with R-32 pressure-temperature curves (not R-410A charts — R-32 operates at slightly different saturation pressures). Verify subcooling with a calibrated pipe-clamp thermometer at the liquid service valve. CoolCloud™ app commissioning confirms airflow CFM, changeover settings, and fault history remotely.
The Professional Standard: R-32 is classified A2L (mildly flammable); EPA Section 608 certification is required for handling. Follow ASHRAE 15 and local mechanical codes for refrigerant charge limits in enclosed spaces. R-32's GWP of 675 (vs. R-410A's 2088) supports current EPA AIM Act phase-down targets and may support IRA/25C tax credit eligibility for qualifying high-efficiency configurations.
Key Benefits
- Variable-Speed Inverter Efficiency: The GZV9S condenser modulates compressor speed to match real-time load, achieving up to 16.5 SEER2 in this configuration — reducing energy consumption compared to fixed-speed systems while maintaining tighter temperature control.
- Cold Climate Heat Pump Performance: With max heating capacity of 48,000 BTU/h at 47°F and operational down to -20°F ambient, this system qualifies as Energy Star Cold Climate Certified, extending efficient heat pump operation deeper into the heating season.
- R-32 Refrigerant (Low GWP): R-32 carries a Global Warming Potential of 675 — approximately 68% lower than R-410A (GWP 2088). This supports EPA AIM Act compliance and may help qualify for IRA/25C federal tax credits for eligible high-efficiency equipment.
- Dual Fuel Flexibility: Automatic switchover between heat pump and 80% AFUE gas furnace heating at the configured balance point, optimizing energy cost based on outdoor temperature and local utility rates.
- Communicating ComfortBridge™ Technology: The furnace's integrated ComfortBridge™ platform enables commissioning and diagnostics via Bluetooth through the CoolCloud™ app, reducing setup time and enabling remote fault-code retrieval.
- Quiet Operation: The GZV9S outdoor unit operates at 77 dBA in normal cooling mode (4-ton) and offers a selectable Quiet Mode with up to 3 sound levels (as low as 45 dBA for the GZV9S platform), minimizing neighborhood noise impact.

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
