Without a working furnace, your home may be without a source of heat. There are numerous potential issues that could reduce your furnace's performance, and knowing about these issues can help you to limit their ability to make your home uncomfortable during cold weather.
Mold On The Interior
Mold on the interior of the furnace is frequently encountered at the start of the heating season as mold may grow in the enclosed space of the furnace during the months when it is not being used. While you may assume that simply running the furnace will be effective for eliminating this mold, it can also spread spores throughout the home. If you notice the presence of mold in your furnace, it should be thoroughly sanitized before turning on the system to neutralize any spores before they can be spread.
Lack Of Heat
The limited heat coming from the furnace is an issue that will also severely decrease the comfort in your home. There are many different potential causes of limited heat from the furnace. For example, a lack of fuel flowing to the system will severely decrease the performance of the system. It can also be caused by clogged filters or a malfunctioning motor.
Burning Excessive Amounts Of Fuel
The amount of fuel that your furnace burns is directly related to the costs associated with running it. As a result, homeowners should strive to keep their system running as efficiently as possible. When a system starts to burn more fuel than normal, it may indicate that there is a need to clean the burner. A dirty burner will waste much of the fuel that flows through it, which can lead to a cycle where excessive residue worsens the performance.
Making Louder Sounds Than Normal
For most homes, the furnace should be a fairly quiet appliance. However, malfunctions can lead to the system making loud grinding, bumping, or clunking sounds that can easily pass through walls. In addition to these sounds being loud enough to potentially disrupt your daily life, they can also indicate a furnace that is on the verge of suffering a major malfunction. For example, the furnace will have mechanical parts that force the heated air through the ducting, and these parts grinding on each other or becoming warped can lead to these noticeable sounds. While older furnaces will be more prone to this issue, newer units that have been poorly maintained can also be at an elevated risk to suffer from these problems.
