Your furnace is a hard-working machine that we don’t think too much about, until it’s not working anymore. That’s why proper maintenance like changing air filters is important to the longevity of your furnace.
There are some tell-tale signs that something isn’t right and furnace repair may be needed. One is when your furnace starts making unfamiliar humming noises.
Here are 5 reasons why you should contact an HVAC company for an appointment, so this noise doesn’t grow into a larger, long term problem.
- Transformer Is Failing: A transformer powers the electrical part of your furnace and if it begins humming or sounding louder than usual, it probably needs to be replaced as soon as possible to prevent additional problems.
- Blower Motor Is Failing: If the blower motor doesn’t’ have enough lubrication, it can cause a loud humming noise and will eventually quit working.
This usually happens when the furnace filters are not replaced regularly, and dirt and debris collect damaging the components.
- Equipment is Loose: Throughout time, if older furnaces aren’t regularly maintained, belts, nuts, bolts and other components become loose and will cause unfamiliar humming noises.
- Ductwork Is Unsecured: Throughout time, the seams and joints in your home’s entire ventilation system become loose resulting in the ductwork to create a humming noise. The ductwork must be to be secured and sealed to prevent further air leaks and noises.
- Failed Capacitor: If your furnace is on, making a humming noise, but the motor is not working, the capacitor may be damaged, and need replaced.
Your furnace is an important part of your home and requires regular maintenance. If you think it sounds odd or isn’t working properly, contact an HVAC company today.
