Chimneys, Fireplaces & Carbon Monoxide Safety

September is when mornings start to feel cooler and the idea of turning on the heat doesn’t seem so far off.

Before you light the first fire or switch your heating system back on full-time, it’s important to make sure everything is safe and functioning properly.

Heating season brings comfort — but it also increases fire and carbon monoxide risks if systems aren’t maintained.

1. Schedule a Chimney Inspection and Cleaning

If you have a wood-burning fireplace, your chimney should be inspected and cleaned annually.

Over time, creosote builds up inside the chimney lining. Creosote is highly flammable, and excessive buildup can lead to chimney fires.

Even if you didn’t use your fireplace often last year, animals, nests, or debris can block ventilation.

A professional chimney inspection checks for:

• Creosote buildup

• Cracked flue liners

• Damaged masonry

• Obstructions

Chimney fires often start quietly and spread quickly. Prevention is far less expensive than repair.

2. Test Smoke and Carbon Monoxide Detectors

Before heating season begins:

• Replace batteries in smoke detectors

• Replace batteries in carbon monoxide detectors

• Test each unit to ensure it’s functioning

Carbon monoxide is odorless and invisible. It can leak from:

• Furnaces

• Boilers

• Gas fireplaces

• Water heaters

• Attached garages

Every level of your home should have working carbon monoxide detection.

If your detectors are more than 7–10 years old, it may be time to replace them entirely.

3. Service Your Furnace or Boiler

Annual heating system maintenance helps:

• Improve efficiency

• Reduce breakdowns

• Identify small issues early

• Ensure safe combustion

A technician will check heat exchangers, gas connections, ventilation, and overall system performance.

Heating systems work hardest during the coldest days — and that’s when service calls are hardest to schedule. September is the right time to get ahead of it.

4. Check Fireplace Surrounds & Clearances

If you use your fireplace, inspect:

• The firebox for cracks

• The damper to ensure it opens and closes properly

• The area around the fireplace for flammable materials

Keep furniture, décor, and rugs at a safe distance from open flames.

Why September Matters

Heating systems sit dormant for months. When they turn back on, problems sometimes surface quickly.

A little preparation now provides peace of mind once colder weather arrives.

Fire and carbon monoxide risks are serious — but they’re also largely preventable with routine maintenance and simple safety checks.

The Bottom Line

Comfort shouldn’t come with unnecessary risk.

Taking time in September to inspect chimneys, service heating systems, and check detectors helps protect your home and everyone in it.
