The furnace is among the most effective heating options in terms of energy use. However, it may make a whistling sound that can be extremely annoying at times. You may also be wondering if you should be concerned when your furnace makes this noise. It depends on what is causing the whistling in the first place. Here are some of the most frequent causes of a whistling furnace.
A clogged air filter might be the source of the whistling. Filters that are unclean make noise and wear down the fan’s motor because it has to work harder to push air through the microscopic pores of the filters.
A Malfunctioning Gas Supply Valve
This problem affects gas furnaces. If the gas valve in your system is damaged, the gas will generally be released at high pressure. The whistling sound is caused by increasing gas pressure.
Leaky Air Ducts
Leaks in the furnace system may be the cause of the whistle. This is often caused by decaying ductwork and a poor connection to the main ducting line. Replacement of the ducts may be necessary if the damage to the ductwork is extensive or if the system is very old.
Hire a Professional to Help You
The concerns listed above may be found during expert furnace maintenance. It is easier and less expensive to repair them if they are discovered during the tune-up rather than waiting until the furnace starts whistling. Regular maintenance is required for your furnace to last longer and cost less in repairs.
