If you need heating furnace repair, this doesn’t necessarily mean that your furnace has stopped functioning altogether. While mechanical failure always needs to be addressed, there may also be subtle indications that a repair may be on the horizon.
If you suspect that you may have an issue, it’s always recommended that you have the repair done promptly, as the malfunctioning component may be taxing other elements of your system and will certainly lower the unit’s efficiency (and raise its cost to operate).
Here’s a closer look at some key indicators that you may need to call in a repair technician.
Common Furnace Repair Issues
While there are potentially hundreds of reasons why you may end up needing furnace repair, there are some issues that emerge much more frequently than others. One of the most common problems involves either the pilot or ignition control. This essentially interrupts flow from the gas line, resulting in intermittent or no heat whatsoever.
Another common furnace issue is a problem with the air flow in the system, which can result either in the furnace overheating or poor heating control. Several components can cause air flow problems, including dirty or clogged filters, a faulty fan motor, and worn belts and/or bearings. Other issues that are frequently seen are worn contractors and faulty gas valves.
Signs You Need Furnace Repair
There are several key indicators that can tell you that you may have one of the above issues or some other type of malfunction in your heating system: Unusual noises: While no furnace is completely silent, any unusual banging, whining, or groaning noises are a good indication that something is amiss. This can be anything from igniting difficulties to a loose or worn belt or other component.
Takes a long time to start: If all of a sudden your furnace is taking a long time to kick on or does not stay on, it’s time to call a repair technician. This type of issue can be caused by a wide range of issues, including a broken thermostat, faulty wiring, pilot light ignition issue, or a problem with the distribution fan motor.
A yellow pilot light: If your pilot light flame is not blue, then you may have an issue that needs repair. Yellow is an indication that dangerous carbon monoxide is present, so this is a repair that needs to be taken care of right away. Carbon monoxide can cause nausea and flu-like symptoms, and in some cases even death.
Failure to properly heat/high utility bills: If you notice that all of a sudden you need to set your thermostat higher than normal in order to stay warm, it’s time to call in a technician. The problem could be anything from a faulty thermostat to leaky ductwork or even a malfunctioning air distribution fan.
