When the stakes are higher
Yes. No hot water is more serious in cold weather and for households with infants, older adults, or people with medical needs — which can make the landlord's duty to fix it even more urgent.
Cold weather makes going without hot water harder and, in some cases, a genuine health concern. Vulnerable household members feel the impact more, whether that is a baby who needs warm baths or someone whose health depends on staying clean and warm. While the landlord's basic duty to provide hot water is the same year-round, the urgency of the repair grows with the circumstances.
If your household includes people who are especially affected, say so when you report the problem, and treat a prolonged outage as pressing rather than routine. If your landlord is ignoring a hot-water outage that is putting your household at risk, a free review can help.
