What SEER measures (and what it does not)
SEER summarizes efficiency across a cooling season in lab conditions. Higher SEER generally means lower electric use — but real-world results depend on sizing, duct leakage, and maintenance.
Humidity and comfort are part of the equation
On the Gulf Coast, latent load (humidity removal) matters. A system that cools quickly but dehumidifies poorly can feel clammy even at a low thermostat setting.
How to choose without getting sold a sticker
Start with correct sizing and airflow, then compare SEER options that fit your budget and expected years in the home.
Common options include balanced-efficiency systems and higher-efficiency packages depending on home size, duct condition, and budget.
FAQ
- Is SEER2 different?
- Yes — updated test procedures change how ratings compare. Your contractor should explain what you are buying in today's SEER2 landscape.
