We all lead busy lives. If your family is anything like ours, a quiet moment is a rare occasion. In the few quiet moments we experience, we hope to hear the sound of birds chirping and the wind blowing peacefully through the trees. Unfortunately, sometimes we also hear another sort of buzzing; the kind coming from the furnace. Why is it making noise and not blowing air?
The test: does the furnace come on and heat the home?
If yes, you probably have a loud standby mode, which is more of an annoyance than an actual problem.
Loud standby mode explained: Your furnace may have a standby mode, which is similar to the ‘sleep mode’ on a smartphone or tablet. The standby mode occurs when your furnace is waiting for a command usually from a thermostat or other communicating device. When it receives a command, for example turning the heat on from a thermostat, the normal sounds of operation will commence, drowning out the buzzing.
If no, the problem is more complex and would require a technician to effectively diagnose it, however, the two top reasons experienced while working in the Smyrna and Marietta, Georgia area are:
- Gasket Dry-Rot (new gasket pictured below): Heating systems, like automobiles, have various gaskets and seals. If they become loose or deteriorate they can cause vibration and/or excessive part wear. When gasket dry-rot is the cause of the problem, repair costs are typically minimal.
- Defective part(s): There are many parts on a residential furnace that can break down and cause unpleasant noise and failure. In these cases, it is best to call a qualified professional to get your system back up and running.
