Signs Your Heater May Need Maintenance Before Winter
Weak or No Airflow
One of the first warning signs of heater trouble is weak or no airflow. This is often caused by a clogged or dirty filter, which forces the system to work harder while delivering less warmth. If left unresolved, restricted airflow can strain your system and eventually lead to a complete shutdown. To avoid this, check and replace your filters regularly—ideally once a month during heavy use. If your filter looks dirty, it’s time for a replacement, or better yet, a professional filter check.
Unusual Noises or Strange Smells
Grinding, banging, or rattling sounds may suggest loose components or internal wear, while burning or musty odors can point to issues with dust buildup or even combustion problems. Ignoring these red flags could lead to dangerous situations or costly breakdowns. The best course of action is to shut the system down and schedule a safety inspection right away to prevent worsening damage.
Thermostat Malfunctions
Another common issue is a malfunctioning thermostat. If your thermostat is not responding properly, or if your home feels inconsistent in temperature despite your settings, the problem may be faulty calibration or wiring. This leads to wasted energy and higher bills, not to mention frustration. Testing your thermostat by adjusting temperatures can help you catch problems early. For peace of mind, a professional tune-up ensures your thermostat is calibrated and working as it should.
Blocked or Obstructed Vents
Sometimes, the problem isn’t the heater itself but rather blocked or obstructed vents. Furniture, rugs, or even dust buildup can prevent warm air from circulating properly, creating uneven heating throughout your home. This forces your system to run longer and harder than necessary. A quick check to make sure all vents are clear and unobstructed can dramatically improve comfort and efficiency.
Drafts Around Windows and Doors
Finally, drafts around windows and doors can undermine your heater’s performance. Even the most efficient system will struggle if warm air is escaping and cold air is seeping in. Worn weatherstripping, unsealed gaps, or leaky windows are often the culprits. By sealing these drafts with caulking or new weatherstripping, you can keep the warm air in, lower your energy bills, and reduce unnecessary stress on your heater.
What to Do If You Notice These Signs
- Run an Early System Test – Turn on your heating before the cold sets in to catch issues early.
- Replace Filters Regularly – A clean filter improves efficiency, lowers bills, and protects the heater.
- Inspect Vents & Airflows – Clear furniture or obstructions blocking vents.
- Seal Leaks and Drafts – Apply weatherstripping or caulk to keep warm air inside and reduce energy waste.
- Schedule a Pro Check-Up – Let our NATE-certified techs conduct a detailed seasonal tune-up—checking burners, heat exchangers, controls, and thermostat calibration.
