The heat was on everyday. We were never contacted or otherwise notified about any heat issues, otherwise we would have brought an additional heater the same day. All calls, txts and emails were answered within minutes. Temperature was at 75 degrees the entire time. I'm very sorry to hear that your husband got sick but considering the flu epidemic in New York during January, its highly likely to be the cause. Again, if there were any issues we were next door and could have helped, anytime. All you had to do was call us.
