SEER rating
SEER stands for Seasonal Energy Efficiency Ratio and measures how efficiently an air conditioner or heat pump cools over a typical season.
Why it matters
Higher SEER means lower cooling costs. Current minimums are higher than older equipment, and premium units can be much more efficient.
Where people get this wrong
SEER is a seasonal average, not a peak rating. Real-world performance depends on installation, duct quality, and maintenance.
Real-world example
An AC from 2005 is rated SEER 10. A new unit might be SEER 16 or higher. That is a significant reduction in cooling costs.
Where this hits your build
This affects daily comfort in every room. Problems often show up after move-in when certain rooms run hot, cold, or noisy.
Most people do not just struggle with terms. They struggle with the decisions tied to them.
