Local considerations
Short but genuine freezes catch systems that have not run in heating mode since the previous winter. In Lawrenceville that determines whether heating calls here are combustion problems or refrigerant-cycle problems, and those need different parts on the truck.
A furnace that has sat idle through the Lawrenceville cooling season accumulates dust on the flame sensor. The resulting lockout after three ignition attempts reads like a failure but is far more often a cleaning job.

Lawrenceville HVAC questions
My furnace locks out after three tries. What is that?
Three failed ignition attempts followed by a lockout usually means the flame sensor is dirty, the igniter is weak or gas pressure is wrong. After a long idle summer, cleaning resolves it more often than replacing parts does.
Is a cracked heat exchanger repairable?
No. A cracked heat exchanger is a carbon monoxide risk rather than a comfort fault, and the correct response is replacement of the furnace. Any provider suggesting a patch on one is giving you poor advice.
Can I run a space heater meanwhile?
Portable heaters carry their own fire risk and should never be left running unattended or near fabric. Never use a gas range or an outdoor appliance to heat a room, which is a direct carbon monoxide hazard.
Do I need a carbon monoxide alarm?
If any gas appliance runs in the home, yes. Carbon monoxide is colourless and odourless, and a working alarm near sleeping areas is the only reliable warning. If one sounds, leave the building and call 911 from outside.
Do you work on boilers in Lawrenceville?
Yes, where a provider covering your ZIP code handles them. Boiler faults run to pressure loss, circulator pumps, expansion tanks and zone valves, which is a different skill set from forced-air work. Say so when you call.
