Heating service
January nights in Newark are cold enough that a furnace that will not ignite is not a wait-until-Monday inconvenience. Gas and oil systems are both common on older streets.

What’s included
Process
Say no heat, ZIP, and fuel type if you know it (gas or oil).
If you smell gas, leave and call the utility.
Ignition, airflow, and safety circuits come first.
You choose the repair path before parts go in.
Why it matters
Fuel-fired heat needs respect. Odors, soot, or a carbon monoxide alarm are stop-and-evacuate situations — not internet fixes.
Oil heat still shows up in older New Castle County stock. Gas furnaces are the majority on post-1970 streets. Both fail on the coldest nights for the same reason: they finally took a real load.

Often ignition, a dirty flame sensor, or a limit trip from airflow. It is a service call, not a thermostat guess.
No. Repeated resets can lock out the board or hide a venting issue.
