3 Things That Impact Proper HeatingShare
Furnace breakdowns are inconveniences that can happen to any homeowner. They often happen unexpectedly. Many of them are caused by lack of maintenance, but there are other factors that can happen to well-maintained furnaces such as frequent breakdowns due to old age. Most furnace repairs can be fixed by requesting an emergency heating service appointment. The following points will help you know in advance common reasons behind furnaces not working.
Furnaces are one part of heating systems. Other problematic parts such as air ducts can negatively impact furnace performance. Leaking ducts result in the loss of heat. This can cause higher heating costs, especially if more than one duct is leaking. Routine heating system inspections can ensure that problematic ducts are identified. Sometimes dirty ducts or severely damaged ducts might require replacing all of the ductwork. This measure will ensure that furnaces do not have to work harder to produce heat and can drastically improve the performance of systems.
This is a part of the furnace that should be changed routinely. Filters are responsible for trapping contaminants such as dust and allowing air to filter through. If they get clogged and air cannot pass through, the heating system's performance might be poor. It is also worth noting that not changing filters can lead to dangerous furnace fires. Another potential consequence is the furnace overheating due to restricted airflow. This can cause damage to the appliance. Some modern furnaces have safety switches that automatically turn them off if they overheat. An HVAC contractor can advise you of the best schedule to change your furnace filter. They can also demonstrate how to perform this important task.
Pilot Light or Ignition Switch
Sometimes the power source is the contributing factor to furnaces not working. Gas furnaces require a pilot light or ignition switch to work. The pilot light will burn a flame. If there is not a flame present, the issue can likely be resolved by relighting. Pilot lights that go out frequently could be a sign of a repair issue. The flame color should be blue. Yellow and orange flames could be a warning that there is a combustion problem or leak. Ignition switches automatically light furnaces. If they do not turn on a furnace, a repair or replacement of the switch will be needed.
An HVAC contractor is a good resource to use to identify early signs that your furnace is at risk of breaking down or needing to get replaced. They can also perform maintenance and repair worn parts. These actions can extend the lifespan of furnaces.
