That winter, when the heat pump reversed cycle to warm her home, she whispered a thank-you to Marco and to the engineers who chased every fraction of a ratio. She had learned that efficiency wasn’t about deprivation. It was about getting exactly what you needed, with nothing left to burn.
The measures how efficiently an air conditioner or heat pump cools a space over a typical cooling season. Like a car's miles-per-gallon (MPG) rating, a higher SEER indicates greater efficiency, lower energy bills, and a reduced environmental footprint. The Basics of SEER seasonal energy efficiency ratio
This is generally the minimum allowed by federal law in many regions. It represents a standard, entry-level efficiency. That winter, when the heat pump reversed cycle
