5 Signs Your Ducted Vacuum System Needs Repairs

A ducted vacuum system is meant to make the task of cleaning less complicated and more cost-effective. However, like any other appliance, it may face some issues with prolonged usage. The best option is to get it repaired as soon as possible. This will not only ensure the reliability of the system but will also allow customers to save money. In this blog, we will disclose the top five symptoms of recognising ducted vacuum suction problems, providing essential tips for its restoration right away.

Here are five key signs that your ducted vacuum needs professional attention.

1. Sudden Loss of Suction

A slow and sudden loss of suction is a common problem faced by homeowners while using a vacuum cleaner. You may know that there is a suction loss problem if your vacuum cleaner does not pick up dirt and makes a weak suction at the wall inlet. Most likely, there are three reasons for the loss of suction:

  • Blockages in the duct: This is caused by a buildup of small objects like toys, newspapers and hair in the duct.
  • Leaks in the hose: Cracks or holes in the vacuum-cleaning hose allowing air to escape.
  • Clogged filters: Filters full of dirt or a container full of dust create obstacles for free airflow in the vacuum cleaner.

If, after emptying the container and checking the hose, you still have a suction loss, you might have a blockage in your vacuum system or an issue with a motor seal, which requires troubleshooting by the professionals.

2. Loud or Sharp Sounds

Since the motor is usually housed in the garage or utility room, ductless vacuums are much less noisy than portable vacuums. If you happen to hear strange noises from the vacuum, you need to take some action.

Grinding, screeching, and loud rattling noises could indicate a faulty motor or a broken fan blade. Eventually, if you continue using a noisy motor, it will stop functioning altogether.

3. Electrical Problems and Temporary Power

When you put your hose in place and nothing happens or the machine stops working during the cleaning process, you may have an electrical issue. Some common causes for this include:

  • Faulty wiring: Any broken signal wires connecting the valves and the power unit.
  • Damaged hose: The electrical wires in the hose may have broken due to bending.
  • Thermal cutout: The safety switch that is supposed to protect the machine from overheating might have kicked in.

If your machine keeps tripping the circuit breaker at your home, turn it off and call an expert to have it fixed.

4. Burning Smells During Operation

The presence of a burning smell, such as that of melted rubber or overheated plastic, is an important cautionary signal. Usually it signifies the following:

  • Overheating of the motor in the event of a complete block.
  • Worn-out carbon brushes are making sparks inside the motor body.
  • Friction due to the fan being stuck or the occurrence of a short circuit.

Precaution: When a burning smell appears, disconnect the unit from the power as soon as possible. Using the equipment further poses a fire hazard and damages the motor.

5. Dust Leaking Out or Ineffective Exhaust System

Your system must capture dust and dirt in the main collection container and exhaust clean air outside or through a closed-off filter system. If you see dust build up inside or blowing from the exhaust pipe, it could mean that the filter is not working anymore.

If there are any leaks in the pipes, the filtration will not work properly, and dust will continue to collect in the walls of your building.
