Common Causes of Furnace Problems
Thermostats can be at the root of several heating issues that range from simple to complex.
There are many reasons why a furnace may malfunction, but some are more common than others. The most common indications of furnace issues are when the furnace struggles to produce heat or produces no heat, a sudden energy bill increase, sudden furnace shut off, and unusual noises. With these symptoms in mind, consider the following causes of thermostat issues to be able to identify and resolve them quickly.
Thermostat settings
Thermostats can be at the root of several heating issues that range from simple to complex. Countless times, residents have noticed that their furnace is not heating correctly or working, only to discover that the thermostat isn’t set correctly in the first place. In these cases, homeowners should check that the thermostat is above the room's temperature, that the settings are on “heat,” and that the fan is set to “auto.”
In more complex situations, the thermostat may malfunction and need repair or replacement. In this case, call a professional to take the anxiety out of this process by providing top-quality repairs and installations to keep the thermostat functioning and the home warm.
Dirty filter
No matter how clean the home is kept, all furnaces eventually become clogged. Whether from dust, pet hair, or other types of common debris, furnace filters typically need to be changed every one to three months. Do not hesitate to call a professional, as they can make this process quick and ensure the job is done right.
Natural wear and tear
The inner workings of a furnace involve an intricate network of mechanical parts that ensure that every interrelated aspect of this machinery is working at top speed and quality. Due to the complexity and high energy output throughout the winter months, it is natural for malfunctions to occur. Unfortunately, these malfunctions can come unexpectedly and at inconvenient times. Therefore, scheduling a cleaning and check for the furnace is essential to ensure the heater doesn’t break down during the coldest months. It’s advisable to contact a licensed professional to thoroughly clean and check the furnace to ensure all systems are working correctly and to fix any problems they may find.
Issues with pilot light or control ignition
A faulty pilot light or control ignition can cause the frustrating issue of intermittent heat, where, at times, the furnace seems to be heating correctly while at others, little or no heat is being dispensed. This could be due to thermostat issues, dirty gas tubes, or drafts.
Aged unit
Some units age past their expiration date. When this happens, it’s time for a replacement. Contacting a licensed professional ensures prompt delivery and installation of a high-quality, long-lasting furnace, saving money in the long run. If the furnace is more than 15 years old, the added expense of its malfunctioning can cause the energy bills to rise substantially, so it’s best to make this replacement as soon as possible.
Perform regular maintenance
Homeowners should aim to prevent issues with their furnaces through regular maintenance. This includes regularly checking the thermostat batteries, the thermostat heat setting, the thermostat temperature, the wiring, the shutoff switch, and the gas valves. Additionally, ensure the thermostat is free of debris and dust and replace the air filters regularly to avoid clogging. When in doubt, it’s always best to call a professional for help, as they’re familiar with all the problems a furnace can experience and quickly resolve any issues.
A functioning furnace is a staple in any household, especially during winter. Homeowners should be aware of all the potential issues their furnace can experience and know how to resolve them should they arise. Often, it’s best to hire a licensed professional to resolve the issue quickly and efficiently.
