If your AC runs all day but some rooms still feel warm, aging ductwork could be wasting your cooling. Ductwork is the hidden highway that delivers conditioned air throughout your home — and when it's old, leaky, or poorly designed, it can lose up to 30% of the air your AC produces.
Signs Your Ductwork Needs Attention
Here are the most common signs that your ductwork might be past its prime:
- Uneven temperatures — some rooms are too hot while others are too cold
- High energy bills — your AC works overtime to compensate for lost air
- Dusty home — leaky ducts pull in dust and debris from attics and crawl spaces
- Noisy operation — rattling, whistling, or booming sounds from the ducts
- Visible damage — disconnected joints, crushed sections, or rust
If you're experiencing any of these issues, it may be time to have your ductwork inspected. At All Valley Air, we can assess your duct system and recommend repairs or replacement to keep your home comfortable and efficient all summer long.
Frequently Asked Questions
How long does ductwork last?
Properly installed ductwork can last 20-25 years. If your home is older and the ducts haven't been replaced, it's worth having them inspected.
How much air is lost through leaky ducts?
The Department of Energy estimates that 20-30% of conditioned air is lost through leaks in typical residential ductwork. That's air you're paying to cool but never reaching your living spaces.
Should I replace ductwork when I replace my AC?
If your ductwork is old or damaged, replacing it at the same time as your AC is often the most cost-effective approach. New ducts ensure your new system performs at its rated efficiency.
