Resident Reports No Heat
TODAY — EMERGENCY in freezing weather
fixRAgentNew photo from a resident
No heat in cold weather is a same-day problem, and an emergency —
when it is freezing,
when anyone in the unit is elderly, very young or unwell,
or when pipes are at risk.
Walk the resident through three checks by message — thermostat on Heat and set above room temperature with fresh batteries, the fan on AUTO, the furnace switch and breaker on — and ask for a photo of the thermostat and the furnace label while you line up an HVAC technician.
Your First Message to the Resident

If they smell gas or a CO alarm is sounding: they leave and call 911 from outside. Nothing else first.

Thermostat on Heat, set above the room temperature, fresh batteries; fan on AUTO (on ON it blows cold air between cycles) [1].

The furnace’s service switch (a light-switch on or near the furnace) and its breaker on.

The filter: if it is grey and clogged, replace it — a clogged filter can make the furnace shut its burners off [1].

How Urgent Is It?

Checks Fixed It
Log it. A clogged filter means the filter schedule is not working.

Power, ignition or control board — HVAC technician today. In freezing weather, agree a temporary heat plan with the resident, and remind them never to heat the home with a gas oven or stove [5].
Who to Send

What to Say to the Resident

“Thanks for checking the thermostat. I’ll book an HVAC technician for today and tell you the time. If you smell gas or a carbon monoxide alarm goes off, leave straight away and call 911 from outside.”

Local Rules
New York City · October 1 to May 31
Heat rules are local and specific. In New York City, for example, from October 1 to May 31 owners must keep apartments at 68°F or more from 6 a.m. to 10 p.m. when it is below 55°F outside, and at 62°F or more overnight regardless of the outside temperature, and provide hot water at 120°F all year [3]. Check your city and state.

Next Time
Have heating serviced every fall and the filter changed on a schedule — ENERGY STAR recommends spring and fall check-ups [4].
