This AHRI-certified Goodman Dual Fuel System (AHRI Ref. No. 215487325) pairs the GZV6SA4810 4-ton variable-speed R-32 heat pump with the GRVT800805DN 80% AFUE two-stage gas furnace and the CHPEA4830D3 horizontal evaporator coil. Rated at 17.0 SEER2 and 8.0 HSPF2, this system delivers efficient year-round comfort with automatic switchover between electric heat pump and gas furnace operation based on outdoor temperature conditions.
The outdoor unit is ENERGY STAR® Most Efficient certified (Cold Climate) and uses R-32 refrigerant with a GWP of 675 — approximately 68% lower than R-410A. The system is AHRI Certified and ETL Listed.

System Components
- Outdoor Heat Pump: GZV6SA4810 — 4-ton variable-speed R-32 side-discharge heat pump with 45,500 BTU/h cooling and 45,500 BTU/h heating capacity (47°F). Features EEV metering, variable-speed swing compressor, and digitally commutated fan motor with Quiet Mode (as low as 45 dBA).
- Evaporator Coil: CHPEA4830D3 — cased horizontal evaporator coil with factory-installed EEV. All-aluminum coil optimized for R-32 refrigerant with built-in R-32 sensor. 30"W × 21"D × 24½"H, 78 lbs shipping weight.
- Gas Furnace: GRVT800805DN — 80,000 BTU/h input (64,000 BTU/h output), 80% AFUE, upflow/horizontal two-stage gas furnace with variable-speed ecm blower motor. Natural Gas rated. 24½"W × 28"D × 33⅜"H, 129 lbs shipping weight.
Pro-Installer Tip
The Technical Friction: On 80% AFUE dual fuel retrofits, the existing metal B-vent flue from the prior furnace often needs resizing to match the new unit's 4" vent diameter — and attic penetrations may not align.
The Long-Term Prevention: After making the vent connection, verify the draft with a manometer under worst-case conditions (blower door at 50 Pa). A marginal draft reading now will turn into a condensation-induced vent failure within 12–18 months, triggering pressure switch lockouts mid-heating season.
The Expert Validation: Use a digital manometer (Fieldpiece SDMN6 or equivalent) to confirm negative draft of at least -0.02" W.C. at the draft hood.
The Professional Standard: Per NFPA 54/ANSI Z223.1, Category I furnace venting must maintain negative pressure throughout the vent system. Many jurisdictions also require CO detection within 15 feet of the furnace.
Key Benefits
- Dual Fuel Efficiency: Automatic switchover between heat pump and gas furnace operation based on outdoor temperature maximizes operating economy — using electric heat pump operation when conditions are mild and switching to gas when temperatures drop below the thermal balance point.
- High-Efficiency Ratings: 17.0 SEER2, 8.0 HSPF2, and 80% AFUE deliver substantial energy savings versus minimum-efficiency (14.3 SEER2 / 80% AFUE) equipment.
- Low-GWP R-32 Refrigerant: R-32 has a GWP of 675, approximately 68% lower than R-410A (GWP 2,088), reducing direct greenhouse gas impact while also providing improved thermodynamic efficiency and lower refrigerant charge requirements.
- Variable-Speed Comfort: The outdoor heat pump uses a variable-speed swing compressor that modulates capacity from approximately 40% to 100%, reducing temperature swings, lowering humidity, and operating at reduced sound levels during part-load conditions.
- Cold Climate Capability: The GZV6SA4810 heat pump operates down to -10°F in heating mode, extending heat pump runtime deeper into the heating season before gas furnace backup engages.

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
