Pro-Installer Tip
[Technical Friction]: The GZV7SA4210 operates on R-32 refrigerant, which is classified as A2L (mildly flammable). When pairing with non-R-32-ready furnaces, ensure you have ordered the R-32 Accessory Kit (Part #0230K00044). Without this kit, the system may not pass inspection and could create a compliance issue with UL 60335 2-40 requirements. Additionally, this side-discharge condenser requires a minimum of 12" clearance on the discharge side and 6" on all other sides — verify this against the existing pad footprint before quoting the job.
[Long-Term Prevention]: During commissioning, verify the switchover set-point (balance point) between heat pump and gas furnace modes is properly configured via the communicating thermostat. A misconfigured balance point leads to excessive auxiliary heat usage and inflated utility bills within the first heating season, which becomes a nuisance callback. Document the balance point setting on the service label.
[Expert Validation]: After evacuating the lineset, pull a vacuum to 500 microns or below and perform a standing decay test for a minimum of 10 minutes using a digital micron gauge (e.g., BluVac+). The EEV in this system is sensitive to moisture contamination — a proper vacuum protects the expansion valve and compressor long-term.
[Professional Standard]: R-32 systems require EPA Section 608 certification for handling. Verify compliance with local mechanical codes for A2L refrigerant installations, including any required leak detection provisions per ASHRAE 15 / UL 60335-2-40. In eligible configurations, this system may qualify for federal energy efficiency tax credits under 25C — confirm AHRI certification number with the IRS qualified product list.
Key Performance Benefits
- Variable-Speed Inverter Compressor: The GZV7SA4210 uses a variable-speed swing compressor that modulates capacity to match the actual load, reducing energy consumption and maintaining tighter temperature control compared to single- or two-stage systems.
- Cold Climate Certified: This system carries ENERGY STAR® Cold Climate certification and Most Efficient 2025 designation, meaning it maintains reliable heating capacity down to 5°F outdoor ambient — rated at 31,000 BTU/h at that temperature.
- Low-GWP R-32 Refrigerant: R-32 has a Global Warming Potential (GWP) of 675, approximately 68% lower than R-410A (GWP 2,088). This reduces the environmental impact of the system over its service life while also improving thermodynamic efficiency.
- Quiet Operation: The condenser features a quiet-mode setting with up to three selectable sound levels, operating as low as 45 dBA — comparable to a quiet library. The high-density compressor sound blanket and digitally commutated fan motor further reduce operational noise.
- Dual Fuel Flexibility: The system automatically switches between heat pump heating and gas furnace backup based on the configured balance point, optimizing between electric and gas costs depending on outdoor temperature and utility rates.
- Communicating System Integration: When paired with a Goodman GTST communicating thermostat, all components communicate over a two-wire connection, enabling automatic airflow optimization, advanced diagnostics via CoolCloud™ app, and simplified commissioning.

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
