Improve Efficiency Where It Matters Most

Your HVAC system can lose energy right at the source.

Koala Insulation of Greenville, a certified Duke Energy Trade Ally, provides targeted duct and air handler sealing—and we handle the $350 rebate process for you.

No paperwork. Just a tighter, more efficient system.

Where Energy Loss Actually Happens

Many homes lose conditioned air not just in ducts—but at the air handler and plenum connections.

Small gaps around the unit, refrigerant lines, and drain lines can quietly reduce system performance and efficiency.

Sealing these areas delivers measurable improvements.

Our Precision Sealing Approach

We focus on the highest-impact leakage points, including:

• Air handler / furnace cabinet sealing
• Supply and return plenum sealing
• All plenum connection points
• Sealing around refrigerant line penetrations
• Sealing around drain lines
• Closing air gaps around and at the HVAC unit

This is not generic duct sealing—it’s targeted system optimization.
