A Revolutionary System Rooted In Simplicity

Rheia is the easiest, most cost-effective way to bring ducts into the home’s conditioned space. Our small diameter system is designed to fit in 2×4 walls and, in all types of floor systems, using 3″ and 4″ uninsulated ducts. Compatible with any conventional air handler, Rheia’s patented snap-fit connections eliminate the need for tape or mastic — leading to a fast, labor-efficient installation.

With ductwork and equipment now entirely in the home’s conditioned space instead of the attic, homeowners will see energy cost savings and experience more consistent temperatures around the house, making it feel more comfortable. And, because the Rheia system is engineered to meet updated and future code requirements, Rheia can lower HERS scores, making the difference needed to achieve the 45L $2,500 and $5,00 per home tax rebates, meeting the required Energy Star requirements.

Leave Leakage Behind

Leave Leakage Behind

Rheia’s patent-pending Ferrule conveniently threads into our duct to create a near airtight seal — making leakage a thing of the past. Exceed Energy Star duct leakage requirements with our durable UL 181 listed duct, and our connector components (Ferrule, Coupler, and Elbow) which meet UL181C and UL2043 standards.

Rheia’s take-offs, floor, wall, and ceiling boots are specified in a UL-94 V-0 rated engineering thermoplastic, with the same performance characteristics as our connector components.

Achieve Balanced Comfort

Achieve Balanced Comfort

Homes can be balanced quickly and accurately using the Rheia Verify process, creating a consistency of temperatures from room-to-room and floor-to-floor, thanks to adjustable, factory-installed dampers located in each duct run. 

Achieve Balanced Comfort
No Change In Static Pressure

No Changes In Static Pressure

Rheia systems utilize a central manifold and work at typical static pressures, which makes it compatible with the air handling equipment you use today. Our proprietary “home run” system discards the conventional “truck and branch” system in favor of a more efficient duct layout that relies on ducts of the same size* to create a balanced, comfortable environment throughout a home.

Small Details Make A Big Difference

Small Details Make A Big Difference

The Rheia air distribution system uses multiple diffusers in each room of a home to ensure a balanced delivery of air in all seasons. Our micro-diffusers, distribute air into a room more effectively, eliminating hot and cold spots — leading to cost savings and improved comfort. Manufactured in high-performance, UV stabilized, engineering thermoplastics, the micro-diffusers are quiet, durable, and designed to last.

Rheia App Used to Commission HVAC System

A Balanced Home In Just 30 Minutes

Equitable and predictable air delivery makes balancing a home easier than ever before! Using our cloud-based, Rheia Verify process you can balance a home in a fraction of the usual time. A 2,500-square-foot home can be balanced in just 30 minutes. The Rheia Verify app checks if system airflows meet design performance, and fine-tune adjustments can be made during the balancing process. Rheia uses ACCA’s Standard 5 recommendations as a benchmark for the performance of our systems.
