Furnaces are generally reliable machines that rarely need repairs. Over time, however, all furnaces will experience issues that impact their functionality and need to be serviced.
Overheating can be dangerous for your family and home, damaging the heat exchanger – potentially endangering both.
Is your furnace in need of repair? Do you think it’s been damaged after a long stretch of poor weather? Click the following URL to get in contact with reliable HVAC technicians that can help you find the solution: https://andersonair.com/residential/furnace-repair/.
1. Burning Smell
A burning smell is often noticeable as soon as your furnace kicks on for the first time in fall. This odor could be due to dust built up over its dormant period being burned off at once.
If the burning smell persists, it could indicate overheating within your system. Prolonged overheating can result in electrical components being damaged – including your blower motor – becoming burnt out due to the constant starting and stopping of the motor.
Furthermore, constant starting and stopping may cause your heat exchanger to warp and crack over time, releasing carbon monoxide into your home.
One way to prevent overheating is to ensure your vents are open and not blocked by furniture, rugs, or other items. While it may seem appealing to close off air vents in rooms you don’t use to save energy costs, doing this may force your heating system to overwork and overheat as designed for heating only one area at once if blocked vents force it to work harder heating all of the house at once.
2. Strange Noises
Furnaces tend to be relatively quiet machines, emitting only a steady hum. When your furnace begins making unusual sounds like banging and clicking noises, this indicates it’s overheating. Overheating can put undue strain on system components that could potentially break down.
Furthermore, overheating puts additional stress on its heat exchanger (where combustion takes place), potentially warping or cracking it and allowing carbon monoxide into your home.
Overheating can cause your furnace to frequently switch on and off – known as short cycling – creating unnecessary stress on the system. If this is happening to you, contact an HVAC professional immediately, as this could indicate an issue with the heat exchanger requiring repairs. Regular professional maintenance visits are essential to help avoid such problems from occurring!
3. Reduced Airflow
Over time, your furnace’s air filter may become covered in dust and lint, preventing its blower from dispensing hot air properly into your home – potentially leading to overheating and other complications in its system.
Overheating could also be a telltale sign that your system is nearing the end of its lifespan and requires replacement to prevent future overheating issues. In such a situation, replacing the furnace might be necessary to keep this from occurring again in the future.
Whenever your furnace begins overheating regularly, it’s essential that you call in an experienced technician immediately. Overheating can damage both its heat exchanger and release hazardous carbon monoxide gas into your home.
A professional will be able to inspect its electrical components closely in order to identify what’s causing it – and can address the problem before it becomes more serious – before fixing or suggesting replacing the unit altogether.
