⚡ The Truth About SEER2 and Your Power Bill

When shopping for a new air conditioner, you’ll hear about SEER2 ratings — the new energy efficiency metric replacing traditional SEER standards. But what does that number actually mean for your utility bill?

SEER2, or Seasonal Energy Efficiency Ratio 2, measures how efficiently an air conditioner uses electricity to remove heat from your home over an entire cooling season. The higher the SEER2 rating, the more cooling you get per watt of energy consumed.

The Goodman 3 Ton R-32 unit is rated at 13.4 SEER2, which equates to roughly 15 SEER under the old rating system. That makes it about 30–35% more efficient than many legacy 10 SEER systems still in operation.

According to ENERGY STAR, each SEER point increase can reduce cooling costs by 5–10%, depending on your home size and climate zone.

Here’s a quick comparison:

*Assumes average electricity cost of $0.14/kWh and 1,800 cooling hours/year.

Savvy’s take: “It’s like fuel efficiency for your home. A higher SEER2 doesn’t just sound nice on paper — it keeps more money in your pocket every summer.”

💡 How to Calculate Actual Energy Use

Understanding what you’ll spend each month starts with a simple formula.

Annual Cost = (Cooling Hours × System Capacity in BTUs ÷ SEER2 ÷ 1,000) × kWh Rate

Let’s break that down:

• Cooling Hours: How many hours your system runs during summer.

• System Capacity: 3 tons = 36,000 BTUs/hour.

• SEER2: 13.4 for the Goodman R-32 system.

• kWh Rate: Your local electricity cost (from your utility bill).

🧮 Example — A Home in Texas

A typical Texas homeowner runs their AC about 1,800 hours per year at $0.14/kWh:

(1,800 × 36,000 ÷ 13.4 ÷ 1,000) × 0.14 = $677 per year

That’s roughly $56 per month in cooling costs across a long season.

Now, if you’re upgrading from a 10 SEER unit, your old cost might have been around $900. That’s a $220 yearly savings, just from upgrading to the Goodman 13.4 SEER2 R-32 model.

According to the U.S. Energy Information Administration (EIA), national average electricity prices have risen steadily over the past few years. Having a higher-efficiency unit means your AC bill won’t climb as fast as energy prices do.

Savvy’s tip: “If your AC runs for 8+ hours a day during summer, even a small efficiency bump pays off in the first two years.”

🌡️ Regional Energy Breakdown — North vs. South vs. West

Not every homeowner experiences the same cooling load. A family in Minnesota might barely run their AC, while someone in Arizona keeps it on nearly year-round.

Here’s how annual cooling hours typically vary:

Savvy’s takeaway:

“Your climate, power rates, and thermostat habits matter as much as the unit itself. The beauty of Goodman’s R-32 design is that it performs efficiently across all of them.”

🧊 Why R-32 Lowers Your Energy Bills

R-32 isn’t just the future of refrigerants — it’s a money-saver today.

Here’s why:

1. Better Heat Transfer: R-32 absorbs and releases heat faster than R-410A, meaning your compressor runs less often.

2. Lower Charge Requirements: Goodman’s R-32 systems need about 30% less refrigerant to achieve the same cooling capacity.

3. Improved Compressor Efficiency: R-32’s pressure curve aligns perfectly with scroll compressors, leading to smoother, quieter performance.

According to AHRI research, R-32 systems can reduce total energy use by up to 12% compared to R-410A models of similar size.

Savvy’s insight: “R-32 is like switching from regular gas to premium fuel — same drive, more mileage.”

So not only do you save on energy — you also gain easier maintenance, quieter operation, and a greener footprint.

Savvy’s reflection: “I used to think ‘new refrigerant’ meant higher cost. Turns out, it means smarter design — and less to spend in the long run.”

🔋 How Smart Thermostats and Maintenance Affect Your Bills

You can have the most efficient AC in the world, but if your thermostat’s outdated or your filter’s clogged, you’ll still overpay.

Pairing your Goodman R-32 unit with a smart thermostat like Nest, Honeywell, or Ecobee can cut cooling costs another 8–10%, according to the U.S. Department of Energy.

That’s because smart thermostats learn your cooling patterns, adjust automatically, and even pre-cool before peak electricity hours.

Savvy’s routine:

• Replace filters every 60–90 days.

• Hose down the outdoor coil once a season.

• Schedule a professional tune-up once a year.

Simple steps like these can extend your system’s lifespan by 3–5 years and keep your efficiency numbers true.

📊 Real-World Examples — What Homeowners Actually Spend

Here’s what real Goodman R-32 homeowners are reporting in different climates:

🌴 Florida Homeowner (2,000 sq. ft.)

• Runs AC 2,200 hours/year.

• Paid $720/year on an old R-410A system.

• After switching to the Goodman R-32 13.4 SEER2: $540/year.
  → Savings: $180 annually.

🌾 Ohio Homeowner (1,600 sq. ft.)

• Runs AC 1,100 hours/year.

• Previous cost: $390/year.

• Now: $300/year, with noticeably quieter operation.

🌵 Arizona Homeowner (1,800 sq. ft.)

• Runs AC 2,000 hours/year.

• Old unit: $820/year.

• Goodman R-32: $630/year, with faster cooling cycles.

You can estimate your own potential savings using the Energy Saver Calculator from the U.S. DOE.

Savvy’s reminder: “No two homes are alike, but the savings story repeats: less power, more comfort.”

🌿 The Environmental Payoff — Efficiency Meets Responsibility

Energy costs aren’t just about money — they’re also about impact.

Every kilowatt-hour saved translates to fewer carbon emissions from power plants. When combined with R-32’s lower Global Warming Potential (GWP 675), the Goodman 13.4 SEER2 unit delivers both financial and environmental returns.

The EPA’s AIM Act targets an 85% reduction in high-GWP refrigerants by 2036, and R-32 is one of the approved low-GWP replacements driving that change.

A 3-ton Goodman R-32 unit:

• Uses ~20% less refrigerant.

• Operates more efficiently (less electricity).

• Has three times less climate impact than R-410A models.

That’s a cooling system that pays you back twice — once on your bill, and again for the planet.

Savvy’s thought: “If sustainability can save me money, that’s a win-win worth celebrating.”

📈 Utility Rebates and Tax Incentives

Many local utilities and state programs now offer rebates for upgrading to energy-efficient systems that meet SEER2 standards or use low-GWP refrigerants.

You can check:

• DSIRE USA – Database of State Incentives for Renewables & Efficiency

• Your local utility’s energy efficiency rebate page

Rebates can range from $150–$500, depending on your state. Combine that with yearly energy savings, and your Goodman R-32 system can pay for itself in just a few seasons.
