Your ductwork may be out of sight, but it shouldn’t be out of mind—especially if you’re noticing inconsistent comfort, high energy bills, or strange noises from your HVAC system. The ducts in your home play a vital role in delivering heated or cooled air where you need it. When those ducts are damaged, leaking, or poorly installed, your entire system suffers.
At Hometown Heating and Air Conditioning, we specialize in professional duct repair in Walnut Creek, CA. Here are the most common warning signs that it’s time to give your ductwork some attention.
1. Uneven Temperatures Throughout Your Home
Do some rooms feel like an icebox while others are stuffy and warm? Uneven temperatures are a common red flag that your ductwork may be leaking, blocked, or poorly sealed.
What’s happening: Damaged ducts allow air to escape before it reaches certain rooms, causing comfort issues and making your HVAC system work harder than necessary.
2. Higher-Than-Normal Energy Bills
If your energy bills are rising without a clear reason—like a heatwave or extended system use—it may be due to duct leaks. According to ENERGY STAR, the average home loses up to 30% of conditioned air through leaky ductwork.
What this means: You’re paying for air that never reaches your living space. Duct repair can help you cut waste and lower monthly costs.
3. Whistling, Rattling, or Banging Noises
While your HVAC system isn’t silent, it shouldn’t sound like it’s falling apart. Whistling noises can point to air escaping through gaps or cracks in your ductwork. Rattling or banging often signals loose or disconnected sections.
Don’t ignore it: These noises can worsen over time and may lead to further damage or system inefficiency.
4. Excessive Dust or Poor Indoor Air Quality
Leaky or damaged ducts can draw dust, insulation fibers, and other airborne pollutants into your system. This debris then gets distributed throughout your home, reducing air quality and potentially aggravating allergies or respiratory issues.
Noticing more dust than usual? It could be a sign your ducts need sealing or repair.
5. Weak Airflow From Vents
If the airflow from your vents feels weaker than normal, your ductwork may be to blame. Collapsed ducts, blockages, or leaks can all reduce airflow and limit your system’s ability to heat or cool your home effectively.
This issue can also lead to: Short cycling, longer run times, and premature wear on your HVAC equipment.
6. Visible Damage or Disconnected Ducts
If you have access to attic or crawl space ducts and notice visible tears, holes, or disconnected sections, don’t wait. Even small damage can have a big impact on comfort and efficiency.
DIY inspection tip: Shine a flashlight along duct seams and connections while the system is running. Look for obvious gaps or listen for escaping air.
