7 Common Signs a Heating System May Need Urgent Repairs

Having a heating system installed at home is an advantageous home feature everyone wants. However, only a few of the lucky ones enjoy a warmer and cozier winter during the holidays for various reasons.

But like most systems, a heating system may also experience failure and make winters even colder at worse. Therefore, which signs should homeowners check to know if their heating system may need urgent repairs?

1. An Expensive Bill

When installed correctly and well maintained, a heating system typically does not produce a high utility bill. If a homeowner notices a sudden spike in their bill, there may be something wrong with the system. It is best to contact a proffessional to come and check out your heating system.

2. Continuous Beeping or High-Pitched Noise

If the pilot is still on, then the home’s pilot light gas valve is emitting noise. If this is the case, the homeowner can hear a beeping sound or a high-pitched sound coming from the fireplace. It could mean that the draft is not proper and that the valve is trying to correct it.

3. Unusual Smell

If a homeowner smells a weird smell coming from their heating system, they should immediately call a heating repair company. The smell could indicate a carbon monoxide leak. If a homeowner, or any other person, notices the presence of this dangerous gas, then they can immediately call the fire department or 911, and they should open windows and also evacuate the area quickly.

4. Frequent Vent Cleaning

If a homeowner’s heating system is venting through a chimney, they should check the chimney for any blockage. This blockage can come from a bird’s nest, a dead animal, or any other material that may have found its way inside the chimney.

Furthermore, if the fireplace is not physically damaged, the homeowner should check the fireplace for damage due to improper venting.

5. Excessive Venting

A homeowner should also check if they have too much or too little venting. If it is too much, then the house may not maintain a safe temperature level. On the other hand, if it is too little, the house may not have enough heat. To maintain a healthy temperature level, the house will have to collect it from the outside and transfer it inside. Therefore, the house will not be able to maintain its warm temperature.

6. Bad Smell

If the home’s heating system is on and you smell an electrical burning smell, it is time to have it checked. This could be coming from key components in your HVAC system. If there is no smell and the heating system is not turning on, with a call for heat, it could mean that there may be something wrong with the power source.

7. Presence of Rust

If homeowners find rust in the heating system, then it is time to call a heating repair company. Because rust can create many issues in the future, such as water leaks, if a homeowner notices rust in the chimney, then there could be a leaky chimney. For this, they should look for the source of the leak and fix it to prevent damage to the fireplace.


Although there are many signs that a homeowner can observe, only a heating expert can properly diagnose the problem. If homeowners see any of these signs, they should call a heating repair company.

Identifying the signs of a heating system failure is crucial for maintaining a household. When someone notices one or more of these signs, they should hire heating repair professionals to fix the issue before it becomes worse. These professionals can then restore the system before it becomes incredibly problematic.
