Ductwork Problems

Ductwork is the essential network of channels that delivers cooled or heated air from your air conditioning unit to the rooms in your home or office. When the duct system becomes damaged, blocked, or disconnected, it can drastically affect your system’s performance. You may notice your air conditioner not cooling, weak or inconsistent airflow, or even your AC not working at all.

A problem with your ductwork is often mistaken for a fault with the air conditioner itself. However, issues like aircon unit with weak air, aircon tripping electric unit, or even AC making strange noises can all stem from the duct system behind your walls or ceiling.

What Causes Ductwork Problems?

Your duct system is mostly out of sight, which makes it easy to forget about, until something goes wrong. Common causes of ductwork failure include:

1. Loose AC Ducts

Over time, vibrations and air pressure can loosen the connections between duct sections. A loose AC duct will allow air to escape into the ceiling or walls, causing a significant drop in airflow.

2. Blocked Ductwork

Dust, insulation, pest infestations, or debris can accumulate in the ducts and restrict airflow. This can lead to your AC freezing up, your air conditioner leaking water, or the unit working harder than necessary to push air through.

3. Duct leaks and cracks

Even small holes or splits in the ductwork can cause cooled or heated air to escape before reaching the vents. This can make your air conditioner not heating or cooling rooms evenly, wasting energy and increasing your electricity bill.

4. Poorly designed or undersized ductwork

If the duct system is too narrow or long, it creates airflow resistance. This may result in weak airflow AC, aircon with no air, or hot and cold spots around your home.

5. Overworked systems due to duct pressure issues

When the system detects a fault in pressure, possibly resulting from a disconnected or restricted duct, it may shut off for safety, causing aircon blowing the breaker or aircon tripping the electric unit.

Warning Signs Your Ductwork Needs Attention

If you’re experiencing any of the following symptoms, it may be time to book professional air conditioning services:

  • Uneven temperatures in different rooms
  • AC blowing hot air on cold setting
  • Aircon blowing hot air in summer when it should be cooling
  • Controller blinking or showing abnormal readings
  • Reduced air coming through one or more vents
  • Higher than usual energy bills
  • Aircon making strange noises such as whistling, banging, or fluttering
  • Damp smells or signs of condensation forming around the vents
  • Frequent need for emergency air con repair

How Ductwork Problems Are Diagnosed and Repaired

Ductwork issues can be difficult to diagnose without the right equipment. At Vital Air Conditioning Services, our experienced technicians carry out a comprehensive inspection as part of our air conditioner repair or aircon maintenance services.

1

Pressure testing and thermal imaging

We use specialised equipment to measure airflow levels, pressure drops, and temperature inconsistencies. This helps locate hidden leaks, blockages, or disconnected sections that are causing your AC not to work as it should.
2

Physical inspection of ducts

In accessible areas, such as roof cavities or under floors, we examine ductwork for signs of deterioration, pests, or disconnected joins. We check for loose AC ducts, kinks in flexible ducting, and sagging or collapsed sections.
3

Sealing and repairing

Our team reseals leaking joints, reconnects loose sections, and removes blockages. If ductwork is too damaged, we may recommend replacement of certain sections. This can immediately improve your system’s ability to cool or heat your home evenly and safely.
4

System recalibration and testing

Once repairs are complete, we run the system to check for aircon error codes, verify airflow at each vent, and ensure that your aircon service has restored optimal performance.

Why Ductwork Issues Should Never Be Ignored

Leaving duct problems unresolved can place long-term strain on your air conditioning unit. If air is escaping or airflow is restricted, your system must run longer to meet the thermostat setting. This can increase wear and tear, leading to more frequent breakdowns and expensive repairs down the line.

Over time, you may find yourself searching for emergency air conditioner repair, especially during the peak of summer or winter when your system is under pressure. Preventative aircon maintenance and timely repairs are always more affordable than waiting until the unit fails.

Frequently Asked Questions

Why is my air conditioner not cooling certain rooms?

This often indicates a ductwork issue such as a disconnected or blocked duct. It prevents cool air from reaching that area, leading to an air conditioner not cooling your home evenly.

Why is my AC airflow so weak?

A weak airflow AC is commonly caused by crushed or leaking ductwork. You may also have a loose AC duct or blocked vent preventing proper circulation.

Can a ductwork issue cause my air conditioner not to turn on?

Yes, especially in modern systems. Faulty duct pressure or blockages can trigger safety shutdowns, resulting in your air conditioner not turning on or showing aircon error codes.

Why is my aircon leaking water or freezing up?

Poor airflow from damaged or obstructed ducts can cause condensation to build up or the evaporator coil to freeze, leading to aircon leaking water or AC freezing up.

Why is my air conditioner making strange noises?

Whistling or banging sounds are often signs of loose or leaking ductwork. These strange noises can also indicate airflow resistance or pressure problems.

Do I need emergency air con repair for duct problems?

If your system is shutting off, blowing warm air, or tripping the electric unit, call for emergency AC repair. Leaving duct issues too long can affect the entire system.
