New York City Comptroller Scott Stringer announced Saturday an audit of NYCHA heating systems after many complaints from tenants saying they're without heat and hot water.

Stringer is calling the vast citywide outages "not an inconvenience" but "a crisis." The comptroller's office says that in the past year, NYCHA has reported a rate of defective boilers that is five times the city average and that more than 11,000 residents suffered outages during last week's storm.

NYCHA is blaming the problem on aging infrastructure.

Recently, complaints have come from tenants at more than 30 NYCHA complexes across the city, including several in the Bronx.

Complaints have come in from the John Adams, Millbrook, Melrose, Sedgwick, Patterson, Soundview, Sonia Sotomayor, Randall Balcom and West Tremont Houses.

They have also come in from the Clason Point Gardens and South Bronx Area Site 402.

The city has vowed to fix the ongoing issues in the complexes as soon as possible.

The city has heat guidelines all landlords must follow. Between 6 a.m. and 10 p.m., if it's below 55 degrees outside, apartments must be heated to at least 68 degrees.

During overnight hours, it must be at least 62 degrees inside homes no matter the temperature outside. Building owners are also legally required to provide hot water year round.

Those who feel their landlord is not complying with the standards are urged to file a complaint by calling 311.
