Boiler system failures in New York City public housing left about 11,000 people without heat or hot water during the winter storm.

The Wall Street Journal says residents in at least 62 New York City Housing Authority buildings lost heat, hot water or both on Thursday.

City officials say crews were sent to repair the boiler systems. The process generally takes about five hours from the time the outage is reported.

Mayor Bill de Blasio made an unannounced trip to the Woodside development in Queens, where about 1,300 apartments were without heat or hot water.

De Blasio says the aging buildings "did not get the kind of maintenance they deserve" for decades.
