I recently created an HVAC ducting shop drawing for the renovation of a 4 bedroom, 4 bath residential apartment on the Upper East Side (UES) of Manhattan, NY. The project involved a modern VRF/VRV air conditioning system with six indoor units and a single condensing unit located in the mechanical room of the apartment.
Let me tell you some more about the project.
The Project Location
The apartment that the work took place in is located at 1107 Fifth Avenue, which is on the UES of New York City. The building has a storied past. It was constructed in 1925 by the George Fuller Company and designed by W.K. Rouse and L.A. Gladstone. It has 26 units spread over 13 stories.
The most interesting part of the building’s history is that George Fuller had to convince Marjorie Merriweather Post Hutton to sell her mansion that occupied the address. He was able to convince her to sell the property to him by agreeing that he would essentially recreate her mansion on the top three floors of the new building. This is a truly remarkable piece of history.
The Project’s Contract Drawing

The HVAC Ducting Shop Drawing I Created
Here is the ductwork shop drawing I created. Please click the image to launch the PDF.
For this project my hvac ducting shop drawing included the following:
As mentioned above, the AC system was a VRF/VRV type with six indoor units and one condensing unit located in a mechanical room within the apartment.
Each toilet and bath was served by an inline duct-mounted exhaust fan. Each fan was connected to a single duct line that terminated at an exhaust louver on the building façade. The kitchen exhaust was provided with a duct connected to the hood and exhausted to the outside through a wall louver. The wall louver measured 30” x 14”, with a 12” wide section for the toilet and bath exhaust and an 18” wide section for the kitchen exhaust.
The condensing unit was ducted to expel hot air to the side of the building and cooled by outside air coming in through the intake louver. The louver measured 66” x 82” (W x H), with the exhaust part 31” high and the intake part 51” high. An opposed blade configuration was used for the louver.
The AC system was divided into six zones, which included the living room, primary bedroom, foyer and bedroom 1, two additional bedrooms, the dining and kitchen area, and the staff and media rooms. Each AC unit was a concealed ducted type located above the ceiling. Supply and return diffusers were either Linear Wall Grilles (LWG) or Linear Ceiling Grilles (LCG), depending on availability or space. Whenever possible, return air to the AC unit was ducted, and if ducting could not be achieved, return via the ceiling plenum was used.
Supply and return ducts were insulated with a 1” liner. Both rectangular and circular ducts were used. Exhaust ducts did not have insulation and terminated at ceiling-type diffusers. Air balance was achieved by using COD (cable-operated dampers), which were installed on each of the supply duct lines.
