This Goodman Dual Fuel System pairs the GZV6SA4810A 4-ton variable-speed inverter-driven R-32 heat pump condenser with the CAPEA4830D3 upflow/downflow cased evaporator coil and the GRVT800805DN 80% AFUE two-stage gas furnace. Rated at 17.0 SEER2 and 8.2 HSPF2 under AHRI Certificate #215487326, this matched system delivers variable-speed heat pump cooling and heating with gas furnace backup for sustained comfort in all climate conditions. The system uses R-32 refrigerant (GWP 675), a next-generation low-GWP alternative to R-410A that supports improved thermodynamic efficiency and reduced environmental impact.

System Components
- Outdoor Condensing Unit: Goodman GZV6SA4810A — 4-ton variable-speed inverter-driven R-32 heat pump with side-discharge cabinet, swing compressor, and EEV metering. Cold Climate rated with quiet-mode operation (as low as 45 dBA).
- Indoor Evaporator Coil: Goodman CAPEA4830D3 — Upflow/Downflow cased all-aluminum evaporator coil with factory-installed EEV, 24-1/2" cabinet width, and R-32-optimized circuitry. 21" depth for easier attic/closet access.
- Gas Furnace: Goodman GRVT800805DN — 80,000 BTU/h input / 64,000 BTU/h output, 80% AFUE, two-stage gas valve, variable-speed ecm blower motor, upflow/horizontal configuration.
Pro-Installer Tip: When pairing the GZV6SA4810A variable-speed heat pump with the GRVT800805DN 80% AFUE furnace, verify the single-wall metal flue vent meets Category I venting requirements per NFPA 54 clearances — this 80% AFUE unit requires proper draft conditions that can be compromised in tight mechanical closets. Set the changeover point (balance point) between heat pump and gas furnace operation based on local fuel costs and climate data; in most regions, the crossover falls between 30-35°F outdoor temperature. Use a digital manometer to verify gas manifold pressure at both high and low fire (if two-stage) — confirming ±0.3" W.C. of spec prevents short-cycling and nuisance lockouts that typically surface during the first cold snap. Check local codes for any requirements regarding combustion air openings to the mechanical room, as this directly impacts safe furnace operation.
Key Benefits
- Variable-Speed Inverter Efficiency: The GZV6SA4810A uses variable-speed swing compressor technology to ramp output up or down based on demand, achieving up to 17.0 SEER2 and 8.2 HSPF2 — reducing energy consumption compared to single-stage systems that cycle between full-on and full-off.
- R-32 Low-GWP Refrigerant: R-32 has a Global Warming Potential of 675, approximately 68% lower than R-410A (GWP 2,088). R-32 also provides approximately 10% higher volumetric capacity than R-410A, enabling smaller compressor displacements for equivalent cooling output.
- Quiet-Mode Operation: The outdoor unit features three selectable quiet-mode levels that reduce sound output to as low as 45 dBA sound pressure at 3 feet — approaching background noise levels for residential neighborhoods and suitable for installations near bedrooms or property lines.
- EEV-Matched Indoor Coil: The CAPEA4830D3 coil features a factory-installed electronic expansion valve (EEV) that precisely meters refrigerant flow across a wider range of operating conditions than fixed-orifice or standard TXV metering, supporting stable superheat and optimal heat transfer.
- Dual Fuel Flexibility: This system automatically switches between electric heat pump operation and gas furnace heating based on outdoor temperature and the installer-configured balance point, allowing the homeowner to use the most cost-effective heating source as conditions change.
- Cold Climate Heat Pump Operation: The GZV6SA4810A is rated for heating operation down to -10°F outdoor ambient, providing heat pump capacity even in extreme cold before the gas furnace takes over — reducing reliance on fossil fuel heating in moderate winter conditions.

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
