A gas smell that won’t go away near a range is a safety matter, full stop, not something to schedule around. If you smell gas: don’t operate any light switches or open flames nearby, turn off the gas supply valve if you can safely reach it, ventilate the area by opening windows, and leave if the smell is strong — then call us (or your gas utility’s emergency line) rather than attempting any inspection yourself.
Once the situation is safe, the underlying cause is almost always a loose connection, a failing valve, or a supply line issue that needs a technician with the right leak-detection equipment — not something to diagnose by smell alone.
