Invisible HVAC - Exactly What We Needed
Katherine P.2 weeks ago

We were renovating an old brownstone and we really needed something that wouldn't mess with the original look of the place. This concealed unit is perfect - we installed it in a cramped closet with just two tiny grilles in the ceiling. It's totally invisible. And it's nice and quiet to boot.

Perfect for our Master Suite
Mark S.1 month ago

We installed over our master bedroom ceiling and ran supply/return to the bedroom and bathroom. It's super quiet - we can't even hear it running even at night. And it looks super clean too without any wall units around.

Luxury Renovation Essential
Elizabeth R.6 weeks ago

Our architect specified these concealed units for our whole home renovation and it looks great. The only visible parts are tiny linear grilles that match our modern design. Worth every penny for the clean look.

Great Unit, Just Plan Your Ductwork Carefully
Thomas J.2 months ago

The unit itself is super quiet and efficient and is totally hidden from view. Just be sure to think through the duct work, you're going to need to have space above the ceiling for the unit (about 12") and to run the short supply ducts. We worked with an HVAC contractor on the design which was a huge help.

Frequently Asked Questions

Do I need an HVAC technician to install this?
Concealed systems require intermediate skills including working with ductwork. The pre-charged lineset simplifies the refrigerant side, but you may want professional help for the duct routing.
What electrical work is needed?
This unit requires a dedicated 208-230V circuit. If you don’t already have a 230V outlet near the outdoor unit location, you may need an electrician to run one.
What if 16 ft of lineset isn't enough?
You can add a 9 ft extension (up to 25 ft total) right from this page for $99. The extension is also pre-charged — no additional refrigerant handling needed.
Does this unit heat and cool?
Yes! This is a heat pump system that provides both heating and cooling year-round. It can heat effectively down to Works to -13°F outdoor temperature and cool in temperatures up to 122°F.
What warranty is included?
All Zone Air systems come with a 7-year compressor warranty and 5-year parts warranty. Register within 90 days for full coverage. We also offer 24/7 technical support and a 45-day return policy.
