Common Heater Failure Signs
Heaters keep our homes warm during cold days. It is important to know when a heater is failing. Early signs help avoid big problems and costly repairs.
Watch for changes in how your heater sounds, works, and smells. These signs show your heater may need attention or service soon.
Unusual Noises
Strange sounds from your heater can mean parts are loose or broken. Listen for banging, rattling, or squealing noises. These noises often point to worn components or airflow issues.
Inconsistent Heat Output
If your heater blows warm air sometimes and cold air other times, it may have a problem. This issue can come from a dirty filter, failing thermostat, or blocked vents.
Frequent Cycling
Frequent cycling means the heater turns on and off too often. It can wear out the system quickly and raise energy costs. Causes include a wrong-sized unit or thermostat problems.
- Short heating cycles
- Long pauses between cycles
- Uneven room temperatures
Strange Odors
Unusual smells from your heater can warn of trouble. A burning smell may mean dust is burning off. A rotten egg smell can point to a gas leak, which is very dangerous.
Increased Energy Bills
| Possible Cause | Effect on Energy Bills |
| Clogged air filters | Higher bills due to poor airflow |
| Faulty thermostat | Heater runs too long or too often |
