SEER, IEER, and IPLV ratings are where most HVAC efficiency conversations begin — but real-world performance often tells a different story.

Most systems spend the majority of their life operating at part-load conditions, not full-load lab conditions.

Our latest blog explains why AHRI ratings don’t always capture what happens in the field and how the APR Control helps improve performance and deliver measurable energy savings where it matters most.

If cutting operating costs and improving system performance matters to you or your customers, this is a must-read.

AHRI full-load efficiency ratings do not reflect real-world part-load HVAC operation. Learn how the APR Control improves energy savings where systems run most.

Heat pumps are everywhere as they are quickly becoming the go-to solution across the industry. The problem is, they are being sized for heating. Cooling performance is paying the price.

Oversized cooling leads to short cycling.
Short cycling kills humidity control.
Comfort and performance suffers, even when temperatures look right.

The problem isn’t the heat pump.
It’s unmanaged cooling capacity.

APR Control® seamlessly provides capacity control in cooling mode without affecting heating operation. The result: longer run times, better dehumidification, and consistent comfort when loads don’t match the system.

This is where the mismatch stops.

In the case of heat pumps, you have to prioritize capacity for either cooling or heating.
