• Headaches or dizziness
• Dead plants near gas lines

Gas leaks are dangerous and require immediate professional attention.

Routine maintenance helps detect gas-related problems early.

Blocked Airflow Reduces Heating Performance

Proper airflow is essential for efficient heating.

Blocked airflow may result from:

• Dirty filters
• Dust buildup
• Blocked vents
• Ductwork problems

Poor Airflow Can Cause:

• Uneven heating
• Increased energy bills
• Overheating
• Reduced comfort

Maintenance helps keep airflow strong and balanced throughout the home.

Blower Motor Failure

The blower motor pushes warm air through the duct system.

If the motor fails, the heater may:

• Stop circulating warm air
• Make loud noises
• Overheat

Causes of Blower Motor Problems Include:

• Dirt buildup
• Worn bearings
• Electrical issues
• Lack of lubrication

Routine inspections help technicians identify motor problems early.

Heat Exchanger Cracks

A cracked heat exchanger is one of the most dangerous furnace problems.

Heat exchangers separate combustion gases from indoor air.

If cracks develop, dangerous gases like carbon monoxide may enter the home.

Warning Signs Include:

• Strange odors
• Soot buildup
• Yellow burner flame
• Headaches or nausea

Professional inspections are extremely important for detecting heat exchanger problems safely.

Carbon Monoxide Risks

Carbon monoxide is a dangerous gas that cannot be seen or smelled easily.

Faulty heating systems may release carbon monoxide due to:

• Cracked heat exchangers
• Blocked vents
• Incomplete combustion

Symptoms of Carbon Monoxide Exposure Include:

• Dizziness
• Nausea
• Headaches
• Fatigue

Regular maintenance helps ensure heating systems operate safely and vent gases properly.

Strange Noises Should Not Be Ignored

Unusual sounds often indicate developing problems inside the heating system.

Common Heating Noises Include:
