Gas leaks range from annoying (drafty windows) to life-threatening (natural gas). The difference in urgency is enormous.
Natural gas smells like rotten eggs — leave immediately and call your gas company. Refrigerant smells sweet/chemical. Duct leaks lose 20-30% of conditioned air.
These guides cover emergency gas response through energy-saving duct and window fixes.
