Lancaster FAQ

Is it safe to keep trying to relight the furnace myself?+

For a standing pilot light on an older furnace, relighting per the manufacturer's posted instructions is usually fine. For a modern furnace with electronic ignition, repeatedly cycling the power switch won't help and can occasionally trip additional safety lockouts. If it doesn't light within a try or two, it's time to call rather than keep resetting it.

Does a furnace that won't ignite mean it needs to be replaced?+

Rarely on its own. Ignition problems are usually a single-component fix. Replacement becomes a real conversation when the furnace is old enough that this is one of several recurring issues, not because of one ignition failure by itself.

Is this guide relevant for Lancaster homes in Dallas County?+

Yes, this applies to homes throughout Dallas County, including Lancaster. If you'd like this looked at for your specific address, call (817) 935-8540 and mention your ZIP code.
