What Is SEER?
SEER stands for Seasonal Energy Efficiency Ratio, a measure of how efficiently an AC system cools over an entire season. A higher SEER number means more cooling output per unit of electricity consumed. The minimum SEER required by federal law for new AC installations in Texas is 14 SEER (as of 2023). Modern high-efficiency systems range from 16 to 25 SEER.
How SEER Translates to Real Georgetown Energy Savings
In Georgetown TX, where AC systems run 3,000-4,000+ hours per year (compared to 1,200 hours in a northern US city), SEER rating has a disproportionately large impact on annual energy costs. Here's a rough comparison for a typical 3-ton Georgetown home:

| SEER Rating | Annual Cooling Hours (Georgetown) | Est. Annual Electric Cost | Savings vs 14 SEER |
|---|---|---|---|
| 14 SEER | 3,500 hrs | ~$1,890/yr | Baseline |
| 16 SEER | 3,500 hrs | ~$1,653/yr | $237/yr |
| 18 SEER | 3,500 hrs | ~$1,470/yr | $420/yr |
| 20 SEER | 3,500 hrs | ~$1,323/yr | $567/yr |
* Estimates based on 3-ton system, Georgetown TX, Oncor/PEC average rate $0.12/kWh. Actual costs vary by home, usage, and electricity rate.
What SEER Rating Is Right for a Georgetown Home?
Our recommendation for most Georgetown homeowners replacing a system: 16-18 SEER. Here's the reasoning:
- The payback period for a 16 SEER vs. 14 SEER system (typically $500-$800 price difference) is 2-3 years in Georgetown, given our long cooling season. That's excellent ROI.
- Going from 16 to 20+ SEER adds $1,500-$3,000 to system cost for $150-$300 additional annual savings, a 5-10 year payback. Reasonable for long-term homeowners.
- Variable-speed 18+ SEER systems also provide dramatically better humidity control, especially valuable in Georgetown's humid springs and falls.
💡 Georgetown-Specific Note: Georgetown homes in Sun City and Wolf Ranch that qualify for Oncor residential rebates may receive $400-$800 back on 16+ SEER qualifying equipment. We handle rebate paperwork for all qualifying ProAir installations.
SEER2 vs. SEER, What Changed in 2023
Starting in 2023, the Department of Energy switched from SEER to SEER2 rating, a more stringent test protocol that better reflects real-world installation conditions. A new 15 SEER2 system is roughly equivalent to an older 16 SEER rating. When comparing systems, make sure you're comparing the same rating standard.
