How it works
Ductless, zoned, whole-home comfort — installed by you.
A single high-capacity MRCOOL® 5th Gen DIY condenser drives up to six indoor heads, each on its own setpoint. No ducts, no demolition, no vacuum pump — every line set ships pre-charged and hand-tightens into place.
One condenser
A high-capacity 5th Gen outdoor unit powers the whole home.
Up to 6 zones
Every room gets its own head and independent thermostat.
No ductwork
Ductless heads mean no demolition and no lost floor space.
One matched kit
We size the load and bundle every head and line set.
Why bother
Ductwork you don't have. Comfort the whole house never shares.
Older and additions-heavy homes rarely have ducts everywhere they're needed. The upstairs cooks, the basement chills, and no single system keeps all of it comfortable at once.
Why not call a contractor
Retrofitting ducts — or a full central system — is brutal.
Adding ductwork tears open walls and ceilings. A whole-home central or contractor multi-zone install climbs to $15,000–$30,000+, and you're still tied to one thermostat fighting the whole house.
The payoff
The whole house comfortable — without a single duct.
