An unexplained whistling noise keeps you up at night. When you least expect it, you hear a banging noise coming from the attic.
The good news is that you don’t have a poltergeist hanging out upstairs. However, you likely need to make a heating, ventilation, and air conditioning (HVAC) appointment in the near future.
Leaky air ducts are known to cause unusual sounds. Often, homeowners don’t realize that the unusual symptoms are tied to ductwork problems. Because leaks can cause higher energy bills, lower indoor air quality, and worse comfort, it’s important to get this issue checked out right away.
Quick Takeaways
- Duct leaks can lead to higher energy costs.
- If you experience uneven temperatures in different rooms, poor indoor air quality, or excessive dust, your ducts may be leaky.
- Through our professional testing, you can locate hidden leaks.
- Once we find the leaks, our timely repairs can boost your home’s comfort and energy efficiency.
What Are the Signs Your HVAC Ductwork Is Leaking?
If you notice the following symptoms, your ducts may have leaks.
1. Your Energy Bills Keep Climbing
When air escapes from your ductwork, your HVAC system has to work harder to replace the lost air. As a result, your energy bills can skyrocket.
2. Some Rooms Feel Hotter or Colder Than Others
Uneven temperatures can occur if the conditioned air isn’t reaching every room.
3. You Notice Weak Airflow From Vents
Note the airflow from different vents. If it varies from one vent to another, you likely have a bent or leaky duct.
4. Your House Seems Dustier Than Normal
If your dust bunnies appear to be multiplying, it might not be a coincidence. Negative pressure caused by a leak can pull air and dust from your crawlspace or attic into the ductwork. Eventually, it ends up in your home.
5. Your HVAC System Runs Longer Than It Should
Extended runtimes can occur if you are losing conditioned air into your crawlspace or attic. The HVAC system has to work harder to replace the lost air.
6. You Hear Whistling or Hissing Sounds
When air is lost to gaps and holes in your ductwork, you may notice whistling or hissing noises. Popping or banging sounds can also occur if the leaks are significant enough to cause major pressure changes in the ductwork.
7. Indoor Humidity Feels Higher Than Usual
Duct leaks can pull in humidity from your crawlspace and attic, which can make your rooms feel clammy in the winter and muggy in the summer.
8. Your Family Has More Allergy Symptoms
An increased rate of allergy symptoms or respiratory problems can stem from leaky ducts.
9. You Notice Musty or Unpleasant Odors
Increased humidity in the ductwork can cause mold and mildew to grow, leading to unusual smells.
10. Certain Areas of Your Home Never Feel Comfortable
If you can’t make certain rooms reach the right temperature, the problem may lie in your ductwork.
11. Your Indoor Air Quality Has Declined
From mold growth to increased dust, duct leaks can negatively impact your indoor air quality. The additional strain on your HVAC system can also cause wear and performance issues, which can harm your air quality.
Why Leaky Air Ducts Affect Indoor Air Quality
The presence of duct leaks can influence your air quality in a few main ways.
- Dust
- Insulation particles
- Pollen
- Increased humidity levels
- Mold and mildew
- Contaminants from the attic or crawlspace
How Professionals Find Hidden Duct Leaks
Our team can locate hard-to-find leaks through several high-tech tools.
Duct Blaster Testing
After sealing off your system, we can use a special fan to test the pressure in your system. The results of this test will tell us if air is escaping.
Airflow Measurements
Then, we can use a special type of smoke in your ductwork to spot where the leaks are occurring. We can also locate the problem area by testing the airflow coming from each vent.
Thermal Imaging Inspections
The conditioned air in your ducts is a different temperature from the surrounding air. With an infrared camera, we can see if conditioned air is escaping.
FAQs
Can leaky air ducts make my house dusty?
They absolutely can. The leaks can pull dust in from the crawlspace or attic. Then, this dust ends up in your rooms.
How much energy can leaking ductwork waste?
Around 30% of conditioned air is lost to duct leaks. This air must be replaced by your HVAC system, resulting in higher energy bills.
Are leaky air ducts bad for indoor air quality?
Yes, they are. Leaky ducts can lead to increased dust, pollen, and mold.
Can duct leaks cause allergy symptoms?
Because of the higher levels of pollen, dust, and mold caused by leaky ducts, allergy sufferers may have more frequent and intense symptoms.
Should I repair or replace leaking ductwork?
It depends on the extent of the damage. Our team can evaluate your duct leaks and determine which approach makes the most sense.
