( Sold & Shipped by Air and Water, Inc.The damaged facade of 261 Madison Avenue (AP) On Sunday morning, a huge commercial air conditioning unit toppled nearly 30 stories to the street as it was being lifted into a Madison Avenue office building. City officials revealed yesterday that the AC unit was 23,000 pounds The unit crashed into the building's facade, sending debris cascading into the street, and then the unit itself tumbled onto a car. Amazingly, the couple inside the car weren't seriously injured. According to the Daily News, "Priscilla and Gregory Welch had just dropped off their daughter at work at Lord & Taylor on Fifth Ave. at 38th St. at 10:43 a.m. when they drove into a downpour of glass, metal and chunks of concrete." Priscilla Welch said, "I was just waiting to be crushed to death."The Elmont woman was at the wheel of the Mazda CX7 and knew she and her husband were in trouble as soon as she turned onto Madison Ave. from 38th St. and saw a construction worker mouthing, “Watch out!”

“Before I knew it, everything started crashing. The car started shaking,” said Priscilla Welch. “I told my husband, just get down, and we got as low as we could. It felt like it was coming at us at over 100 mph. It was coming from all directions, I couldn’t tell if it was from right from left.” Priscilla said a chunk of debris the size of a boulder hit the back of the Mazda, where their daughter had been sitting 30 seconds earlier. central ac units cost“I tried to continue to drive to get away from it as far as we could,” she said. central ac unit does not turn onShe plowed into a fire hydrant, causing her air bag to deploy in her face.do you cover ac unit winter Eight other people were injured. The Department of Buildings' investigation is ongoing, and a full vacate order remains in place for 261 Madison.

Officials say the "DOB will be examining all open and active crane rigging work performed by the company working at 261 Madison Avenue as a precautionary measure." Damage at 261 Madison Avenue (WABC 7) WABC 7 reports that the floor apparently buckled when the unit was being placed: "Workers experienced a sudden shaking and the floor buckling. There was a weight shift, and the air conditioning unit fell. Investigators are looking at what caused the floor to buckle, saying that either the payload was too heavy for the floor, or there could be a defect in the floor." A steel beam also crashed through the ninth into the eight floor. And when the unit hit the street, it caused a small break to a 12-inch water main. The Daily News, which described the AC unit as being the size of a shipping container, spoke to a business owner who was "shocked," but also found a bright side, "It's better it happened on Sunday because Monday to Friday at working time [there are] a lot of people."

This is what I wrote then. "I tried two different units and they both stunk. The cool air blowing out was only marginally cooler than a regular fan circulating the existing room's air.

Worse, the heat eminating from outside was horrendous. The installation kits had a thin, flimsy plastic piece with a hole in it (to accommodate the hose), which sets into a window frame. It would have required a trip to the hardware store and funky rigging to seal most of it tight. I returned each unit the following day." 342 posts, read 947,030 times 12,267 posts, read 11,899,712 times 1,642 posts, read 1,539,796 times Mitsubishi Mr. Slim Ductless Air Conditioner - Buy Online & Save! If you have money to burn, this would be something to look at Originally Posted by Pink Jazz I'd love to be able to do this but my two window ac's are affordable, and this isn't. One of them is ready to be replaced with something less noisy but for now it runs. I've seen that system and it sounds great IF you have the money. I assume its less common than central AC because if you can afford it you can also afford central ac. The mechanical systems of Scaife Hall in 1961 were much different from today.

There were three heating and air conditioning units serving the whole building. The mechanical room was located on the basement floor where two heating & AC units were installed. The #1 heating & AC unit was dedicated to the conditioning work of the basement, ground floor, first floor and second floor spaces, while the #2 heating & AC unit served the nearby Lecture Hall on the first floor. For the third floor, there was a penthouse beyond it, which was equipped with the #3 heating & AC unit to serve the third floor. The most significant feature of the mechanical systems in 1961 was the implementation of dual-duct air mixing boxes to control and handle indoor air. All air cells shown on the drawings were in the floor construction above. The ceiling of this floor was used to serve the air mixing boxes on the floor above. Besides the regular internal air supply outlet, there were a set of sill treatment units installed along the building envelope to control the peripheral air temperature.

The air to the window sill treatment shall be supplied from the air mixing boxes at the ceiling below. The renovation in 1995 removed all the dual-duct air mixing box and implemented a new central air conditioning system. The first floor applied a window air distribution system and fan coil units were installed below the windows on the second and third floor. For the fourth floor a plenum air return approach was also implemented. Same as in the 1961, air handling units located in the mechanical room served the basement, first, second and third floor spaces while another air handling unit in the penthouse served the fourth floor. On each of the floors, there was an exhaust air duct that could help discharge the exhausted air from the restrooms. In addition, a reheat system was implemented for the basement and a reheat/recool system was established on the fourth floor. The most up-to-date renovation of the mechanical systems of Scaife Hall was finished in 2004. The HVAC systems for the basement and the first floor were totally redesigned and for the second to fourth floor, designers modified the existing ducts, pipes and diffusers by rearranging them.

After renovation in 2004, conditioned air for the basement and the first floor comes from air handling units located in the mechanical room with a heat recovery system while the penthouse is responsible for the second to fourth floor spaces. In particular, the second to fourth floor remained all the features of renovation in 1995 except for some changes in the distribution of ducts and diffusers. However, for the basement, a total five reheat units were added, which resulted in the change of pipes and ducts correspondingly. As for the first floor, a floor plenum air supply coupling with a ceiling plenum air return system were introduced. It is also notable that the air supplied by the duct is just for ventilation purpose and fan coil units take responsibility to undertake the thermal loads. The reason why duct works were sometimes overlapping and too complex is that designers would like to utilize the old duct work to reduce cost. Also, there is no ventilation in the stairwell areas.
