How to Tell When Your Heater Needs Repairs
A properly working heater is essential for getting through Ontario’s cold winters, but how can you tell when it’s time for repairs? Sometimes, the signs are easy to spot, while other times, they can be more subtle. Paying attention to how your heater behaves can help you address small issues before they become major problems.
Call Marx Mechanical Heating and Cooling if you’ve noticed:
- Unusual noises. Banging, rattling, or squealing sounds coming from your heater could indicate loose components, a malfunctioning motor, or other internal issues.
- Uneven heating. If certain rooms feel much colder than others, it might mean there’s a problem with your ducts or the heater’s ability to distribute heat properly.
- A sudden spike in your energy bills. An inefficient heater requiring repairs often consumes more energy to provide the same level of heat, which can cause your bills to go up even if your heating habits haven’t changed.
- Persistent cool air blowing from your vents. This could signal a broken or malfunctioning part, like the heat exchanger or blower.
- Strange smells. Burning or musty odours coming from your unit could be caused by electrical issues, dirt buildup, or even a gas leak, which requires immediate attention.
If you’ve noticed any of these signs, don’t hesitate to reach out to Marx Mechanical Heating and Cooling. Our expert technicians are here to restore your heater’s performance and keep your home comfortable.

Common Causes of Heater Issues
Heater issues can arise from a variety of causes, some of which are surprisingly common and easy to address. One leading cause of problems is a lack of regular maintenance. Over time, filters can become clogged with dust and debris, restricting airflow and reducing the efficiency of your heating system. Similarly, worn-out components like belts or motors can lead to unusual noises or reduced performance. Scheduling routine check-ups with a professional can help catch these issues early and keep your system running smoothly.
Another frequent culprit is a malfunctioning thermostat. If your thermostat isn’t calibrated correctly or the batteries are low, it may struggle to communicate with your heating system, leading to inconsistent temperatures or a heater that won’t turn on at all. Additionally, electrical issues within the system – such as frayed wires or a tripped circuit breaker – can cause your heater to shut down unexpectedly. By staying vigilant and addressing these common problems promptly, you can keep your system dependable and your home warm.

Can a Broken Heater Be a Safety Hazard?
A broken heater can be a safety hazard if certain issues are not addressed promptly. One of the main concerns is the risk of carbon monoxide leaks in heaters that use gas or oil. If there is a malfunction or a crack in the heat exchanger, dangerous levels of carbon monoxide could escape into your home. Since carbon monoxide is odourless and invisible, it can go unnoticed until it causes serious health issues like headaches, dizziness, or even life-threatening poisoning. Installing carbon monoxide detectors and scheduling regular maintenance for your heater are essential steps to prevent this danger.
Another potential hazard is the risk of fire. Faulty wiring, overheating, or debris buildup inside the heater can spark a fire, especially with older systems or those that are poorly maintained. Additionally, a malfunctioning heater may overheat certain areas, creating a burn hazard for anyone who comes into contact with it. To minimize these risks, make it a habit to inspect your heater for any signs of unusual noises, smells, or malfunctions, and contact a professional for repairs if needed.
