Exposure to piercing temperatures is perilous. That’s why you rely mostly on your furnace to provide the heat you and your family need. But sometimes, furnaces fail, leaving you in the cold. When something like this happens, you would immediately call your trusted heating company in Chanhassen MN, right? But it helps to find out the reason why your unit fails to perform its job, which may mean something as simple as a filter replacement.
Marsh Heating and Air Conditioning has teams of qualified and seasoned heating specialists who can help you restore your heat in no time. In this article, we’d like to shed some light on why furnaces are unable to work as they should.
Clogged Filters
As mentioned earlier, putting back your heat can be as easy as replacing your filter. The main function of this part is to protect the blower fan from accumulating dust, debris, hair, and other particles that can cause it to be clogged. A clogged filter can cause the furnace to turn itself off.
A dirty filter is the most common cause of furnace issues. Dust and debris restrict airflow, and when the filter gets clogged, the heat exchanger will overheat and shut off too quickly, which results in your home not receiving heat.
Also, all the dust and debris accumulated by the filter will force the furnace to work hard and use more energy to heat your home. Regular cleaning your filter protects your furnace from being damaged and ultimately, shutting down completely.
Dirty Burners
Your furnace involves a process that burns fuel, and over time, the burners collect dirt, reducing the unit’s heat output. In such a case, you will need to clean the burners. This process includes several steps and requires a certain level of experience to perform them safely. It’s best to leave the job to a professional who will give your burners a thorough cleaning and make your furnace work again.
Duct Issues
When you notice cold spots in your home—some rooms are colder than others— the ducts may have cracks or holes that let out warm air indiscriminately. The dampers, which are the handles that stick out from the ducts, are responsible for controlling the airflow. You will want these parts to be fully open for the ducts to work properly.
If you notice that some rooms are still uncomfortably cold, this may indicate leaks or damages in your ducts. Leaky ducts are no joke as they can easily increase your fuel costs without necessarily producing your desired heat.
To temporarily fix duct issues, you must first detect the leaks and seal them off with special metal duct tape. But for a permanent solution, you will need to contact a heating professional.
Pilot Light or Ignition Control Issues
Most modern furnaces use an electronic ignition system that produces a spark to light the pilot, which serves as the ignition point when gas flows into the heating system. Ignition problems can be exposed by turning the power off to the furnace and resetting the circuit breakers.
When your furnace’s ignition control is faulty, it can negatively impact your heating system’s ability to work properly, shutting down the furnace entirely. If your furnace has a standing pilot light, a faulty thermocouple can cause pilot light issues since the thermocouple is responsible for detecting whether the pilot light is functioning. If the pilot light goes out, the furnace has no way of turning on the heat. Such a problem calls for the help of an expert, so call your preferred HVAC contractor.
Blower Motor Problems
Your furnace’s blower is responsible for the heated air reaching its intended destination. It is the part of your furnace that circulates the heated air throughout your home. If the blower motor is faulty, your furnace cannot circulate warm air. The furnace may ignite and engage properly, but a malfunctioning blower motor will not kick in and no air will move around, leaving your household chilly and uncomfortable.
