We are often asked how to connect a Midea, Whynter, Danby, Toshiba, etc. Single Duel Duo Hose into our Under Garage Door Narrow Vent as the single hose design is not a standard hvac connection.
Here is a List of everything you’ll need to make the connection happen.

PURCHASE LIST
- Duo Duel Hose Splitter (Converts the Single Duel Hose into 2 – 5.9″ Hvac hoses
- Second 5.9″ Portable AC Exhaust Hose – Here on Amazon. (It does not matter which thread direction, as it’s a slip on with clamp design connection.)
- Qty 2: Under Garage Door Narrow Vents WITH 5.9″ HOSE ADAPTER & Extended Wings Options
(One for Inflow & One for Outflow) - Optional: 5.9″ to 5.9″ Connector – If you need to Extend Your 5.9″ Hose. You’ll also need a second 5.9″ Hose from Amazon. Best practice is to keep the hose as short as possible, but some setups require a bit longer run.
- Optional: AC Hose Insulated Cover Sleeve – Here on Amazon
(This is optional but highly recommended. The Output Tube can become very hot and radiants heat back into your conditioned space. This sleeve will help insulate the tube.) Really anything such as a towel, etc. will help keep the hose insulated.
Here’s an example of what your cart will look like. Remember to purchase the extra 5.9″ hose from amazon if you don’t have one already. (Notice you get a discount for purchasing 2 vents at the same time.)

Below is what your finished product should look like once assembled. You can then run each 5.9″ Hose to our Under Garage Door Narrow Vents.
