Proven performance and reliability over thousands of case studies

Over 5,000 Measured Case Studies

Bluon has partnered with Cortland to retrofit over 30,000 residential mini-split systems.

Every Cortland unit is measured for efficiency and capacity using MeasureQuick and FieldPiece Gauges.

On average, retrofit units increased 4 SEER points (rising from 8 to 12) while gaining 25% capacity.

Cortland is nominated for the 2021 REME Award for its retrofit partnership with Bluon.
