Pro-Installer Tip: Dual Fuel Switchover & R-32 Charge Verification
The Technical Friction: Dual fuel systems with R-32 require precise outdoor thermostat lockout calibration. The GZV7S communicates with the furnace control board to manage switchover, but if the balance point is set too high, the gas furnace cycles unnecessarily — costing the homeowner on utility bills. If set too low, the heat pump runs below its rated COP threshold, struggling in temperatures where gas heat would be more efficient.
The Long-Term Prevention: After final charge adjustment per the Installation Instructions, verify subcooling at the service valve target of 9±1°F using a calibrated digital manifold gauge. Log the charge weight and subcooling reading on the unit’s startup checklist. Six months post-install, a routine check at the service valves confirms no slow leak has degraded system efficiency or triggered nuisance fault codes on the 7-segment LED display.
The Expert Validation: Use a Testo 557s or Fieldpiece SMAN460 digital manifold with R-32 refrigerant profiles loaded. Cross-reference superheat and subcooling against the expanded performance data tables in the GZV7S engineering spec sheet for the actual outdoor ambient at time of commissioning.
The Professional Standard: R-32 is classified as A2L (mildly flammable) under ASHRAE 34. Ensure the installation complies with UL 60335-2-40, and verify your jurisdiction has adopted the 2024 UMC or applicable local mechanical code provisions for A2L refrigerants. The GZV7S ships with a factory-installed R-32 sensor on the outdoor unit, but confirm the indoor unit sensor (if applicable) is properly positioned per the installation manual. Document EPA Section 608 technician certification and R-32 charge weight on the permit paperwork.
Key Benefits
- High-Efficiency Rated Performance: This AHRI-certified system achieves 18.5 SEER2 and 8.5 HSPF2, delivering measurable energy savings compared to minimum-efficiency (14.3 SEER2) systems. The variable-speed inverter compressor in the GZV7SA3610 modulates capacity to match the actual load, reducing short-cycling and improving humidity control.
- R-32 Low-GWP Refrigerant: R-32 has a Global Warming Potential (GWP) of 675 — approximately 68% lower than R-410A (GWP 2,088). This supports compliance with EPA AIM Act phase-down requirements and positions this system for long-term refrigerant availability. R-32 also has higher volumetric cooling capacity, meaning smaller charge quantities for equivalent performance.
- ENERGY STAR® Cold Climate Certified: This combination meets the stringent ENERGY STAR Cold Climate criteria, verifying effective heating performance at outdoor temperatures down to 5°F. The GZV7SA3610 delivers 22,000 BTU/h at 5°F, maintaining heat pump operation well below typical balance points.
- Dual Fuel Flexibility: The GRVT800805CN gas furnace provides 80,000 BTU/h backup at 80% AFUE, automatically engaging when outdoor temperatures drop below the heat pump’s economic balance point. This combination optimizes utility costs by using the most efficient heat source for each temperature range.
- Quiet Operation with Sound Control: The GZV7SA3610 features a high-density compressor sound blanket, quiet digitally commutated fan motor, and field-selectable Quiet Mode with up to 3 sound levels (as low as 45 dBA). The side-discharge cabinet design with grille-style sound control further reduces perceived noise at the property line.
- Diagnostic Intelligence & Communicating Control: The system includes a 7-segment LED display with fault code storage, proprietary Inside Intelligence for diagnostics, and full communicating capability requiring only two low-voltage wires between indoor and outdoor units. Compatible with the Goodman GTST connected thermostat for enhanced monitoring.

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
