As a homeowner who doesn’t spend every day diagnosing and repairing heating issues, it can be difficult to know what to do when your heating system isn’t working as it should. Catching an issue early is important—and potentially cost-saving, which is why we’re sharing the most common performance issues we encounter every day.
Take a look at these 6 signs that your heating system needs repair, you may be able to head off larger issues and keep your home feeling comfortable in every room, all year long.
1. Your heating system is blowing cold air
Why is my heating system blowing cold air? This is a common frustration we hear from homeowners during the colder months. The answer, however, isn’t simple since a system that is blasting chilly air can have several causes, including dirty filters, a tripped breaker, a gas supply interruption, or an iced-over heat pump unit, to name a few. Because there are so many possible causes, it’s best to reach out to a heating services expert for a professional diagnosis.
2. Your furnace is becoming noisy
If you have to turn up the TV volume every time your furnace cycles on could be a sign your system needs attention. Unusual sounds such as squeaking or banging are not typical of a properly functioning heating system. These sounds could be caused by a clogged burner, airflow reductions, or a number of other mechanical issues.
3. Your fan or blower runs continuously
When a heating system’s blower is constantly running, it could be the result of a problem with its limit switch. In this situation, work with a professional to properly diagnose the root cause and you may need to have the part replaced.
4. Your system is frequently cycling on and off
If your heating system is cycling on and off over a short period of time, it may be the result of improper airflow, a clogged filter, or a bad thermostat. A factory trained technician can help identify the problem and keep it from adding undue wear on your system.
5. Your ignition or pilot light isn’t working properly
If your ignition system or pilot light is faulty you will experience problems with heating your home. Issues with clogs, drafts, or a thermocouple can result in an unlit pilot light or one that is flickering or faint.
6. Your thermostat is malfunctioning
Problems with your thermostat should definitely be addressed and repaired. As the brain of your HVAC system, your thermostat instructs which components to function and for how long. If your heating system is not turning on or only runs for short periods of time before shutting off, your thermostat may be to blame. Your thermostat may need to be replaced to ensure your system can run properly again.
By knowing the first signs that something is amiss with your heating system, you can avoid unexpected breakdowns AND extend the life of your heating system. That’s because even abnormal wear and tear can negatively impact your heating systems overall performance.
Years of regular use without proper maintenance will eventually lead to decreased performance, airflow issues and overall limited heat control. That said, many of these issues can be prevented by simply scheduling an annual system tune-up, which will allow your heating system to run more reliably and efficiently.
Lastly, be sure to note the age of your system as you consider repairs. The lifespan of a typical furnace is between 15 and 20 years. If your unit is nearing the end of its life, the expense of replacement and more efficient function might outweigh the cost and headaches of future repairs.
