Real-world efficiency and savings comparisons
so you can confidently save money without sacrificing comfort.
⚡ Section 1: What Determines AC Efficiency?
SEER2 Ratings
Seasonal Energy Efficiency Ratio 2 (SEER2) measures how efficiently your AC cools your home throughout the season. The higher the SEER2 rating, the lower your energy use for the same cooling output.
-
Older units (pre-2006): SEER 10–12
-
Modern units: SEER2 14–18+ (varies by model)
Key Efficiency Factors:
-
Compressor Type: Single-stage vs. two-stage vs. variable-speed.
-
Refrigerant Type: R-410A or R-32 (newer refrigerants improve efficiency).
-
Coil Design: Impacts heat transfer and airflow.
-
Proper Sizing: A correctly sized unit runs efficiently; too large or small increases energy waste.

🛠️ Section 2: Does Cosmetic Damage Impact Efficiency?
Scratch and dent units typically have external cosmetic flaws that do not impact internal components. These include:
-
Small side panel dents
-
Scratched paint
-
Bent base edges
These issues do not affect SEER2 ratings or energy performance if: ✅ Coils are undamaged ✅ Fan motors are properly aligned ✅ Refrigerant lines are intact
Reputable suppliers test scratch and dent units to confirm they operate to factory standards before selling.

⚠️ Section 3: Potential Issues to Check
While most dents are harmless, you should inspect for:
-
Bent Coil Fins: Can reduce heat exchange efficiency.
-
Crushed Lines: May cause refrigerant leaks.
-
Fan Alignment Issues: Can cause noise and reduce airflow.
-
Cabinet Frame Deformities: May lead to vibration or rattling.
✅ Always request clear photos of the unit’s dents and test documentation.

📈 Section 4: How to Maximize Efficiency After Installation
Correct Installation is Critical:
-
Verify refrigerant charge is accurate.
-
Ensure proper airflow and duct sealing.
-
Confirm thermostat calibration.
-
Use a professional installer to maintain warranty and efficiency.
Maintenance to Protect Efficiency:
-
Clean coils annually.
-
Replace filters every 1–3 months.
-
Keep outdoor units clear of debris.
-
Schedule annual professional inspections.
✅ AC Installation Costs to understand installation costs worth paying to protect efficiency.
🌱 Section 5: Efficiency vs. Cost Savings Comparison
Utility Bill Comparisons
-
Replacing an old SEER 10 system with a SEER2 14.5 unit can reduce cooling costs by 20–40%.
-
Example: Mark’s summer cooling bills dropped from $220/month to $165/month after his upgrade.
ROI with Scratch and Dent
-
Save $800–$1,500 upfront on the unit.
-
Continue saving on utility bills.
-
Typical ROI within 2–3 years.

🛡️ Section 6: Warranty and Efficiency Protection
-
Confirm SEER2 rating and refrigerant type with the seller.
-
Ensure the unit retains a manufacturer warranty or comes with a seller warranty.
-
Register your unit after installation.
-
Use licensed installers to maintain warranty validity.
