Air ducts are vital parts of your air conditioning system. But even when they're maintained with regular cleaning and inspections, issues can sometimes come up. Thankfully, there are usually signs that you need air duct repairs, so you can take care of the problem before it becomes a major hazard. Here are some to look out for.

When to Call for Air Duct Repairs

1. Strange Sounds 

You shouldn't be able to hear any sounds coming from the air conditioner other than the steady hum of the compressor. If you hear noise coming from the ducts themselves, like banging or whistling, something is wrong. There could be a problem with the airflow, such as a loose connection or duct leak, causing too much or too little air pressure. 

2. Unpleasant Odors 

If a bad smell comes out of the vents every time the air conditioning comes on, it may be the result of mold or a pest infestation. In either case, immediate air duct repairs are necessary to prevent a health hazard, as breathing in mold and bacteria can cause or worsen respiratory illnesses. 

3. Uneven Temperatures 

When the temperature is noticeably different from room to room without any differences in thermostat settings, the ducts might be blocked or damaged. A crack or leak in the ducts can cause some rooms to feel noticeably colder than others, while a blockage from dust and dirt or a pest infestation can make some rooms feel warmer than others.

4. Visible Dirt & Dust Around Vents 

Although a small amount of dust around vents is normal, if you notice a significant buildup or have to clean the vents every few days, then something is wrong with the filtration system. A problem with the vents can prevent them from properly filtering dust from your home, and that buildup can get into the AC system's mechanical parts and cause a breakdown. You might also notice the AC filters need to be changed more often when there is a duct issue. 

5. Sudden Spike in Energy Bills 

Although your bills can fluctuate throughout the year, a sudden, unexpected increase is a sign of trouble. Damaged ducts can increase AC usage and drive up costs. A loose connection might also be letting out air and require professional repair.
