Amana MDK01QW Main Duct Kit - for J And K Series PTACs, Quiet White Color - AMDK019003

The Amana MDK01QW Main Duct Extension Kit along with the PTDK01QW is  specifically engineered for use with J and K Series PTACs, serving as a seamless solution to extend air distribution to an adjoining room. This kit conveniently attaches to the top of the existing PTAC air discharge grille, acting as the base section of the duct for connecting additional extension ducts. It also includes the transition duct kit.
To complete the installation and ensure optimal functionality, it is essential to acquire the EDK02QW Extension Duct Kit and the TDK02QW Terminal Duct Kit, both of which are available individually on our site. These components collectively facilitate the transfer of air between rooms, allowing for a customizable airflow distribution.
Please note that the MDK01QW Main Duct Kit and the PTDK01QW Transition Kit are an integral part of a comprehensive system, and proper installation requires the additional purchase of the EDK02QW Extension Duct Kit and TDK02QW Terminal Duct Kit, all available individually on our site. Together, these kits enable efficient and customizable airflow distribution for enhanced comfort in both the room of origin and the adjoining room.

Features

• Attaches to the top of the existing PTAC air discharge grille.
• Base section of duct for connecting additional extension ducts.
• Extends air distribution to an adjoining room.
• Finished in Quiet White to seamlessly match Amana J/K Series PTAC units.

What our Experts Think

• Purpose-built airflow expansion accessory
  The Amana MDK01QW is a main duct kit designed for J and K Series PTAC units, allowing a single PTAC to extend conditioned air into an adjacent room instead of cooling just one space.
• Improves multi-room climate control efficiency
  Enables controlled air distribution between two spaces with adjustable airflow balance (typically 65/35 to 80/20 split, depending on configuration), improving comfort without adding a second unit.
• Clean, integrated design
  Finished in Quiet White to match Amana PTAC units, helping it blend seamlessly into installed wall systems for a more professional, built-in appearance.
• Modular system (not a standalone kit)
  Works as part of a 3-piece duct system (main duct + transition + extension/terminal kits), giving installers flexibility but requiring full compatibility planning for proper setup.
• Best suited for hospitality and multi-room layouts
  Commonly used in hotel suites, apartments, and extended-stay units where one PTAC needs to serve a secondary connected room without installing additional HVAC equipment.
• Expert verdict
  A specialized airflow distribution upgrade for Amana PTAC systems, best for users who need cost-effective cooling expansion into an adjoining room, but not relevant for standard single-room installations.

Q&A

Q: What is the Amana MDK01QW used for?
A: It is a main duct extension kit designed to allow an Amana J or K Series PTAC unit to send conditioned air into an adjacent room, instead of cooling only one space.

Q: Which PTAC units is it compatible with?
A: It is specifically made for Amana J-Series and K-Series PTAC systems, ensuring proper airflow connection and fit.

Q: What does the kit include?
A: The MDK01QW acts as the base main duct and transition assembly, connecting to the PTAC discharge grille and supporting additional duct components for extended airflow.

Q: Does it include all parts for a full two-room setup?
A: Not by itself. A complete installation typically also requires extension ducts (EDK02QW) and terminal kits (TDK02QW) to fully distribute air between rooms.

Q: What is its main benefit?
A: It allows a single PTAC unit to condition two connected rooms, improving efficiency in hotels, apartments, or multi-room layouts without installing a second unit.

Q: What color/finish does it come in?
A: It comes in Quiet White, designed to match Amana J/K Series PTAC units for a clean, uniform wall appearance.

Q: Can airflow be controlled between rooms?
A: Yes, the system can be adjusted to distribute air between rooms at different ratios (commonly 65/35 to 80/20, depending on configuration).

Q: Who is this product best for?
A: It’s ideal for hotels, guest suites, rentals, or home setups where one PTAC unit needs to cool multiple connected rooms efficiently.

Maintenance Tips

• Balance airflow split correctly: Start around 70/30 (main room/secondary room) and adjust based on comfort. Too much diversion reduces main-room cooling.
• Avoid long duct runs: Keep secondary room ducting as short and straight as possible to prevent weak airflow.
• Seal all joints tightly: Even small air leaks reduce efficiency and increase PTAC workload. Use HVAC foil tape, not regular tape.
• Don’t block return airflow: Both rooms need proper air return paths or the system will feel weak and uneven.
