Why it matters to you
Many Lowcountry furnaces sit idle most of the year in humid attics, garages, and crawlspaces, where moisture and corrosion can take a toll. An annual safety inspection before the first cold snap is the time to catch a compromised heat exchanger.
Practical guidance
Install working carbon monoxide alarms on every level of a home with gas appliances. If an alarm sounds or you suspect a gas or exhaust problem, leave the house and call for help; a heat exchanger inspection is a job for a licensed technician.
