Here’s something most people find out the hard way: furnaces tend to fail when you need them most. Not in September when the weather is mild. In January. During a cold snap. On a weekend.

The reason is simple. A furnace that’s been sitting unused all summer may have small issues that went unnoticed. The first time it runs hard — really runs — those small issues turn into big ones.

The Case for Fall Maintenance

Getting your furnace serviced in the fall, before heating season starts, is one of the easiest things you can do to protect your home. A technician will inspect the heat exchanger for cracks, test the ignition system, clean the burners, and make sure everything is working safely and efficiently.

This visit also catches the things homeowners can’t see — like a heat exchanger that’s beginning to crack and could leak carbon monoxide into the home. That’s not a scare tactic. It’s just a real thing that happens in older furnaces that haven’t been maintained.

What to Watch For

Even between service visits, pay attention to these signs:

• Your heating bills are noticeably higher than last year
• The furnace makes banging, squealing, or rattling sounds
• Some rooms heat up fine but others stay cold
• The furnace kicks on and off more frequently than normal
• You notice a burning smell when the heat first comes on

Any of these is worth a phone call.
