How Leaky Air Ducts Affect Your Energy Bill and Air Quality
How Leaky Air Ducts Affect Your Energy Bill and Air Quality
05Jul 2025

Most homeowners rarely think about their air ducts. Can you blame people? These ducts are hidden behind walls, ceilings, and floors, and most people are content as long as hot or cold air is coming out of the vents. Here’s the kicker though: those hidden air ducts can be sneaky little energy thieves. If they’re leaky, they’re quietly draining your wallet and affecting the air you breathe.

To make matters worse, they often go unnoticed for years - until the problems are too big (and too expensive) to ignore. In this brief article brought to you by Purified Air, we break down how this happens and what you can do about it. If you'd rather consult a technician from a reputable HVAC company, then call or message Purified Air to get in touch.

The Job of Your Air Ducts

Your air ducts are the channels that carry heated or cooled air from your HVAC system to the rest of your home. When those conduits have holes or detours, less of that conditioned air actually makes it to your destination. That is, if your air ducts are leaking, damaged, or poorly sealed, then a huge chunk of that conditioned air never makes it to your living spaces.

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

In fact, the average home loses about 20 to 30 percent of its conditioned air through duct leaks, according to ENERGY STAR. Imagine running your heater or AC at full blast and only getting 70% of the comfort. Sounds wasteful, right? That’s because it is.

Higher Energy Bills, Lower Comfort

One of the first signs of leaky ducts is a spike in your energy bills. It's simple, really. If your HVAC system is working harder to make up for lost air, then it’s using more energy. That means higher heating and cooling costs without better results.

You might also notice some rooms are colder or hotter than others. That’s because the air is not being distributed evenly. Your system keeps running and trying to meet the temperature set on your thermostat, but it’s fighting a losing battle. This puts unnecessary strain on the system and can lead to costly heating repair down the line.

If left unchecked, leaky air ducts can warrant a full heat repair or HVAC system replacement much sooner than expected.

Air Quality Matters Even If You Don’t See It

Leaky ducts don’t just waste energy; they also pull in dust, dirt, allergens, and even mold from unconditioned spaces like attics, crawl spaces, and walls. All of that ends up circulating in your indoor air.

Our Services

We provide expert heating solutions, including installation, repair, and maintenance. Our team ensures energy-efficient systems for maximum comfort.

You may not notice it immediately, but poor indoor air quality can make life much more uncomfortable if you or your family suffer from allergies, asthma, or other respiratory issues. That’s why it’s so important to catch these issues early and schedule air duct repair before the leaks start affecting your health.

So, What Can You Do?

If your energy bills are climbing, your rooms feel unevenly heated or cooled, or you notice an increase in dust or allergy symptoms, then ring the alarm bells because you've got a problem. Here’s what you should consider:

  • Schedule an HVAC Inspection: An experienced technician from a reputable HVAC company like Purified Air can inspect your ductwork to check for leaks, gaps, or poor connections. We’ll also evaluate your system’s overall performance and airflow.
  • Seal or Repair Your Ducts: Technicians can seal leaks using specialized materials or replace sections of damaged ductwork entirely. This helps your system run more efficiently and improves comfort throughout your home.
  • Regular Maintenance: Annual maintenance by a trusted HVAC technician in Pasadena keeps your system running smoothly by patching spot small issues before they become big headaches. It’s your best defense against surprise breakdowns and expensive heat repair calls.

Still have questions, concerns, or hesitation? Call or message Purified Air to get in touch with a courteous member of our team. We're happy to schedule a face-to-face meeting or onsite visit for as soon as possible.
