Are Your Air Ducts Leaking? Here’s How to Tell (No Tools Needed)
Are Your Air Ducts Leaking? Here’s How to Tell (No Tools Needed)
26Sep 2025

Your HVAC system is one of the hardest-working systems in your home. It keeps you warm in the winter, cool in the summer, and comfortable all year long. But if your air ducts are leaking, much of that heated or cooled air never makes it to your living spaces. Instead, it’s wasted in attics, crawlspaces, or walls, causing higher energy bills, uneven temperatures, and unnecessary strain on your system.

The good news? You don’t need fancy equipment or a technician’s toolkit to spot the warning signs of leaky ducts. At Purified Air, we help homeowners understand what to look for so they can take action before the problem worsens. Here are some simple ways to tell if you need air duct repair—no tools required.

1. Your Energy Bills Are Climbing

Have you noticed your utility bills creeping higher month after month, even though your HVAC usage hasn’t changed? Leaky ducts may be the culprit. When air escapes into unused spaces, your system has to work harder and run longer to keep your home at the right temperature. That wasted energy shows up on your bill.

After hearing great things from my neighbor, I decided to try Purified Air Heating and Air Conditioning for a heating system check-up. They did not disappoint. The team was courteous, on time, and very knowledgeable. It’s clear why they came so highly recommended, and I’ll be sharing my positive experience with others in the neighborhood

Tip: Compare your bills year over year for the same season. A significant unexplained increase could signal duct leaks.

2. Rooms Feel Unevenly Heated or Cooled

Does one room feel like a sauna while another is freezing? Uneven temperatures throughout the house are a classic sign of duct leaks. If air isn’t reaching certain areas, your system can’t properly regulate comfort. Instead of blaming your HVAC unit, it may be the ducts delivering less air where you need it most.

3. Weak Airflow from Vents

Place your hand over a vent when the system is running. If the airflow feels weak compared to other vents, air could be escaping before it ever reaches that room. While clogged filters or dirty coils can also reduce airflow, duct leaks are often the hidden reason.

4. Dust and Poor Indoor Air Quality

If you’re constantly dusting but can’t keep up, your air ducts may be pulling in dirt from attics, crawlspaces, or basements through cracks and leaks. Those contaminants then get circulated throughout your home. Leaky ducts not only waste energy but can also worsen allergies and respiratory issues.

5. Strange Odors or Drafts

Do you sometimes smell musty or unusual odors when your HVAC runs? That may be air being pulled in from damp, dusty areas of your home. Similarly, unexpected drafts in rooms with vents may be caused by imbalanced airflow due to leaks.
