When shopping for a new HVAC system, the terms “single-stage” and “two-stage” can feel confusing. Do you really need staging technology in your Goodman 5 Ton system? Or is the single-stage version perfectly fine for your home?
The choice impacts comfort, efficiency, and cost. In this guide, I’ll walk you through exactly what staging means, the pros and cons of each option, and how to decide which Goodman 5 Ton setup fits your family, your climate, and your budget.
📘 What Does “Staging” Mean in HVAC?
When we talk about stages, we’re referring to how many levels of output your air conditioner or furnace can operate at.
-
Single-Stage Systems:
-
Operate at 100% capacity or nothing—they’re either on or off.
-
Like flipping a light switch.
-
-
Two-Stage Systems:
-
Can run at low stage (about 65–70% capacity) or high stage (100%).
-
Like a dimmer switch on a light.
-
👉 Why it matters: two-stage systems provide more flexible performance, which can mean smoother comfort and lower energy bills.

⚡ Single-Stage Goodman 5 Ton System: Pros & Cons
Goodman offers reliable single-stage systems that are built for affordability and simplicity. Here’s what I learned:
✅ Pros
-
Lower upfront cost: Usually $1,500–$2,000 less than a comparable two-stage system.
-
Simple design: Fewer moving parts, easier maintenance.
-
Reliable: Goodman’s single-stage units are sturdy and dependable.
-
Good for mild climates: If your summers aren’t scorching or humid, single-stage works fine.
❌ Cons
-
Less efficient: Tends to use more energy in part-load conditions.
-
On/off cycling: Can cause temperature swings and uneven comfort.
-
Poor humidity control: Especially in humid states, these systems don’t run long enough at lower speeds to dehumidify properly.
-
Noise: Louder because they always run at full blast.
For durability, Goodman is one of the better choices in this category. But you trade comfort for affordability.
🌡️ Two-Stage Goodman 5 Ton System: Pros & Cons
Two-stage systems are designed for homeowners who want more consistent comfort and efficiency.
✅ Pros
-
Better comfort: Runs longer at low stage → even temperature throughout your home.
-
Superior humidity control: Especially important in southern states.
-
Higher efficiency: Uses less energy at low stage, leading to 10–15% lower cooling bills.
-
Quieter: Lower stage means quieter operation most of the time.
-
Qualifies for rebates: Two-stage often meets higher SEER2 ratings, making you eligible for incentives.
❌ Cons
-
Higher upfront cost: Expect $10,500–$12,500 installed.
-
More complex: More parts = potentially more service needs.
-
ROI depends on climate: If you live in a mild area, the extra efficiency may not pay back as quickly.

📊 Cost Comparison: 2025 Pricing
Here’s a realistic cost breakdown for Goodman’s 5 Ton combo systems (AC + coil + 80k BTU furnace) in 2025:
-
Single-Stage System:
-
Equipment: $4,500–$6,000
-
Installed: $8,500–$10,000
-
-
Two-Stage System:
-
Equipment: $6,000–$7,500
-
Installed: $10,500–$12,500
-
That’s about a $2,000 difference between the two.
But here’s the catch: if you live in Texas or Florida, a two-stage unit may save you $150–$200 per year on utilities, meaning it could pay itself off in under 10 years.

🏠 Which System Fits Your Home Best?
Let’s break it down by climate, budget, and lifestyle.
🟢 Choose Single-Stage If:
-
You live in a mild climate (Oregon, Northern California, Pacific Northwest).
-
You’re on a tight budget and want reliable cooling.
-
You don’t mind minor temperature swings.
-
Your home is smaller (under 3,000 sq. ft.) with average insulation.
🔵 Choose Two-Stage If:
-
You live in a hot, humid climate (Texas, Florida, Georgia).
-
Your home is large (3,000–3,600 sq. ft.) or has high ceilings.
-
You want steady comfort with fewer hot/cold spots.
-
You plan to stay in your home for 10+ years and value long-term ROI.
🌍 Efficiency & Environmental Impact
Pairing two-stage technology with R-32 refrigerant makes a noticeable difference:
-
R-32 transfers heat more efficiently than older refrigerants.
-
Lower Global Warming Potential (GWP): 675 vs. R-410A’s 2,088.
-
Meets 2025 EPA standards, ensuring your system is future-proof.

🔊 Comfort Factors: Noise & Humidity
This was big for me:
-
Single-stage: Louder when running, and because it cycles on/off, you notice it more.
-
Two-stage: Runs quietly at low stage, blending into the background.
Humidity-wise:
-
Single-stage: May leave indoor air sticky in humid climates.
-
Two-stage: Runs longer, pulling more moisture out of the air.

🏦 Rebates & Tax Credits
In 2025, rebates and credits can make two-stage systems more attractive:
-
Federal Tax Credits: Up to $600 for qualifying ACs that meet SEER2 standards.
-
Utility Rebates: Many states offer $200–$1,000 for high-efficiency systems.
-
Manufacturer Rebates: Goodman dealers sometimes run promotions.

✅ Samantha’s Take: Which Should You Choose?
Here’s my personal takeaway after comparing quotes for both:
-
If you’re budget-conscious and in a mild climate, Goodman’s single-stage 5 Ton system is a solid, affordable choice.
-
If you’re in a large home in a hot, humid climate, I’d strongly recommend the two-stage system. The comfort difference is real, and the energy savings will add up.
-
Either way, Goodman’s reliability and R-32 refrigerant make both systems a smart investment in 2025.
🔑 Final Thoughts
Deciding between single-stage and two-stage comes down to this:
-
Single-stage = lower upfront cost, reliable, best for mild climates.
-
Two-stage = higher upfront cost, smoother comfort, best for hot/humid areas and large homes.
No matter which you choose, make sure your contractor does a Manual J load calculation so your Goodman 5 Ton system is sized correctly. Installation quality matters just as much as staging technology.
With the right choice, you’ll enjoy decades of comfort and efficiency—and peace of mind knowing your home is future-ready with R-32.
