Since January 2023, all new residential AC systems sold in the South region of the US — including Texas — must meet a minimum SEER2 rating of 15.2. But minimum isn't always optimal. Here's how to choose the right efficiency tier for your Spring TX home.

SEER2 (Seasonal Energy Efficiency Ratio 2) measures cooling output per unit of electrical energy consumed. The '2' reflects a new, more rigorous testing protocol implemented in 2023. SEER2 ratings are roughly 5% lower than equivalent SEER ratings — a 16 SEER system roughly equals 15.2 SEER2.
💰 Cost: SEER2 15.2 minimum in Texas as of Jan 2023
15.2–16.5 SEER2 equipment is the current minimum and offers significant improvement over older 10–13 SEER systems. Best for: homes where upfront cost is the primary concern, rental properties, or homes where you plan to sell within 3–5 years. Monthly savings vs. a 13 SEER system: approximately $50–$80/month in Texas summer.
💰 Cost: Best for: cost-focused, shorter-term ownership
17–18 SEER2 represents the best long-term value for most Spring TX homeowners. The $1,500–$2,500 upfront premium over minimum-tier equipment typically pays back in 3–5 years through energy savings, then continues saving for the remaining 7–10+ years of system life. Also offers better humidity control.
💰 Cost: Best for: most Spring TX homeowners staying 5+ years
Variable speed systems (19–24 SEER2) run at 40–100% capacity continuously rather than on/off. Benefits: dramatically better humidity control, whisper-quiet operation, smallest temperature swings, and maximum efficiency. Higher upfront cost ($2,000–$4,000 more) — best for larger homes and long-term ownership.
💰 Cost: Best for: larger homes, long-term owners, comfort-focused
In Spring TX's 9–10 month cooling season, a high-efficiency system runs far more hours than national averages suggest. Every SEER2 point of improvement saves approximately 6% in cooling energy consumption. Over 15 years in Texas, the difference between 15.2 and 18 SEER2 on a typical home can exceed $3,000–$5,000 in total energy savings.
💰 Cost: Calculate savings at your current electricity rate
The minimum in Texas is 15.2 SEER2. For most Spring TX homeowners who plan to stay 5+ years, 17–18 SEER2 typically offers the best long-term value — the energy savings pay back the premium within 3–5 years. Variable speed systems (19+ SEER2) offer the best comfort and efficiency for larger homes and long-term ownership.
SEER2 uses a more rigorous testing protocol introduced in 2023 that better reflects real-world conditions. SEER2 ratings are approximately 5% lower than the equivalent SEER rating. The minimum for Texas changed from 14 SEER to 15.2 SEER2 in January 2023. All new equipment sold in Texas since then must meet this standard.
For most Texas homeowners staying 5+ years: yes. The 9–10 month cooling season means significantly more operating hours than the national average, which amplifies the energy savings from higher efficiency. A 17–18 SEER2 system typically pays back its premium in 3–5 years then continues saving through the system's life.
The Carrier Comfort series installs at 16.5 SEER2. The Carrier Performance series offers 18 SEER2. The Carrier Infinity variable speed series offers 20+ SEER2. AC Repair Expo installs all Carrier efficiency tiers and can help you calculate which makes most sense for your specific home.
