Are your energy bills too high for your comfort? One of the major causes of increased energy bills is leaky air ducts.
Holes and loosened joints in ductwork allow for heated or cooled air to escape through the cracks, decreasing your HVAC system’s efficiency by 20% to 30%. When your HVAC system isn’t as efficient as it could be, it consumes more power, driving up energy costs. Not to mention, the system is wasting energy heating or cooling areas of your home that don’t need it, like your attic.
How can you fix a duct leak? Sealing your ductwork can help you save almost $200 a year on total energy costs.
In this blog, we’ll explain more about how leaky ducts can increase your monthly utility bills. We’ll also review how you can tell if you might have holes or cracks in your ductwork beyond higher energy costs.

How Duct Leaks Increase Your Energy Bills
Every home’s ductwork system has two types of air ducts:
- Return ducts: These ducts suck in warm air from the home into the AC system.
- Supply ducts: These ducts blow out cool air into the home.
Both types of ducts can leak but in different ways.
Return Duct Leakage
Return ducts, which draw in air, are often in areas like the attic that don’t have air conditioning or heating. If they have holes in them, the extra warm air in the unconditioned attic or the extra cold air in the unheated attic will end up going into the return ducts. Consequently, the return ducts will bring in a higher temperature, forcing your HVAC system to work harder and longer to reach your desired temperature.
Supply Duct Leakage
On the other hand, supply ducts, which supply heated or cooled air to your home, can also be affected by leaky air ducts. If they have holes in them, your HVAC system will expel energy to heat or cool air that ends up escaping before it has a chance to be dispersed throughout your home. Worse, your HVAC system will then run longer to reach your desired temperature.
Duct sealing will help decrease your energy bills and can be worth it for other benefits such as:
- Improved energy efficiency
- Improved home comfort
- Healthier air quality
- Qualifying for a $400 rebate from SRP

Signs of a Duct Leak
The main sign that your home might have leaky ductwork is higher-than-normal energy bills, even if your usage remains the same.
Other signs include:
Certain areas/rooms won’t properly cool down or heat up:
Holes, gaps, or cracks in your supply ducts mean that conditioned or heated air is lost before it ever reaches its final destination. And depending on where those leaks are, that could mean that one room might get a lot less heating or cooling than others. So, you might notice some rooms in your home are colder or warmer than the rest because they aren’t getting the same treatment.
AC system taking longer to cool or heat your home:
If there are leaks in your return ducts, your AC system will pull in more humid and unfiltered air, which will cause the evaporator coil to become dirty and clogged. Evaporator coils contain refrigerant, which absorbs heat from your home’s indoor air to be dumped outside. Coils covered in debris prevent the refrigerant from absorbing and dumping heat well, slowing down the cooling process.
Your home is more humid than normal:
While Arizona is a desert, it does get humid sometimes. Leaks in your home’s return ducts can cause higher indoor humidity levels. AC systems can cool and strip humidity from indoor air but cannot keep up with properly dehumidifying air if too much humid attic air has entered the return ducts. Over time, if your home stays too humid, it can lead to issues like minor mold growth, bug infestations, and other health problems. Resolving mold requires hiring a mold remediation company and can be a pricey service.
Excessive dust in the home:
As mentioned above, leaks in your return ducts pull in dust and other debris from your attic. Anything that makes its way into the return ducts gets pushed into the supply ducts and, eventually, your home. If your home is excessively dusty despite frequent cleaning, you most likely have leaks in your return ducts. Or you might have unexplained allergies or respiratory problems. On top of duct sealing, it’s good to have your ducts thoroughly cleaned.
