Jan 22

For that, you can contact the pros for immediate heating system repair in Hammond, LA

What’s the Main Role of a Capacitor? 

Aside from providing a jolt of energy to switch on the blower motor, a capacitor is built to tolerate higher current loads and have more charge storage capacity. 

That’s why, when damaged, your furnace won’t provide any heat, making your winter experience a disaster. So, you can have it inspected to determine early warning signs of a problem. 

How to Know if Your Capacitor Has Gone Bad

It is easy to determine when your capacitor gets damaged. If you start to notice a humming sound, it might indicate an electrical problem that requires a quick fix.

While you may be tempted to address the problem independently, nothing can beat a quality heating system repair in Hammond, LA from the pros.

So, when the blower motor has been acting strange these past few days, please do not hesitate to schedule a heating system repair in Hammond, LA right away. 

A sudden furnace shutdown may also mean a faulty capacitor. This is especially true when your capacitor does not respond even after adjusting the thermostat settings.

What Are the Factors that Contribute to Furnace Capacitor Failure? 

Everything happens for a reason. So, when your capacitor does not function at its best, there are various factors to look into.

Some of them are given below: 


It is always recommended to invest in a cutting-edge HVAC component. But its quality will decline after a few years. The capacitor, for example, will eventually fail because of normal wear and tear.

Worn-Out Bearings 

It is normal for any appliance to get warm when in use. Overheating is not the same thing, though. If your capacitor burns up, the culprit could be worn-out bearings in the fan motor or compressor. 

So, do not leave the capacitor in the circuit for a long time. For other expert maintenance tips, contact a certified technician.
