Get safe
Gas odor or CO alarm: leave, then utility or 911.
No heat
A furnace that will not ignite at 11 p.m. in January is a different problem than an AC that can wait until morning. If you smell gas or a carbon monoxide alarm is sounding, leave first. Then contact the utility or 911 from a safe location.

If you smell gas, a carbon monoxide alarm is sounding, you see fire or smoke, or equipment is sparking, leave the area and contact the appropriate emergency service or utility from a safe location. Do not operate switches, the thermostat, or the furnace until the home is cleared.

Why it matters
Newark sits in a mixed-humid climate that still needs real winter heat. Emergency heating is the no-heat path. Emergency cooling is listed separately so the wrong playbook is not applied.
Oil and gas furnaces in older 19711 and 19713 stock, heat pumps on newer Bear and Christiana streets. Both fail on the first true cold snap.

No. It is a carbon monoxide and fire risk. Close unused rooms and wait for service.
No. Timing is confirmed when the team follows up. This site does not invent dispatch windows.
