The two were found on the 10th floor of the apartment building. They were taken to the hospital in serious condition, but as of late Friday both were expected to recover.
Fire officials said there were problems with the home's smoke detectors.
"This time it might be a good reminder for everybody watching we'd like you to change the batteries in your smoke detectors twice a year when Daylight Saving Time changes. That way we know that they're operating," said Fire Department Captain Joe Principio. "It didn't appear that the smoke alarms were functioning, whether the batteries were removed or the just weren't functioning at all. So just a reminder for everybody to take care of that."
Daylight Saving Time ends Sunday at 2 a.m., when the clocks move back one hour.
