When extreme heat raises the stakes
During a heat wave, a broken AC can become a serious safety concern even though AC is not generally required — especially for children, older adults, or people with health conditions. Where the landlord provided the AC, they should repair it promptly.
Extreme heat can be dangerous, so treat a broken AC in a heat wave as urgent, particularly for vulnerable household members. Report it to your landlord in writing, document the indoor temperatures, and take steps to stay safe, such as using local cooling centers if you need to.
If the landlord provided the AC, they generally must maintain it, and dangerous conditions strengthen the case for a quick response. Combined with a lease that included AC, a local cooling rule, or a medical need, a heat-wave failure can raise real legal questions. If a broken AC in extreme heat is putting your household at risk and your landlord will not act, a free review can help.
