Your ductwork plays a critical role in the efficiency and overall comfort of your home. They are responsible for transporting air from your home through your HVAC system and back to maintain the optimal internal temperature.
Leaky ducts are a common but often overlooked issue in many homes, and they can have a big impact on HVAC efficiency.
If your ductwork isn’t sealed correctly, air can escape before it even reaches your living room, bedroom, kitchen, and entire home, leading to several costly and inconvenient problems.
As the trusted San Antonio HVAC company since 1979, Wright Home Services specializes in all things heating and cooling, including full system replacements, simple repairs and tune-ups, and duct repair and replacement.
While we understand how detrimental leaky ducts can be to your HVAC health and home’s comfort, we’re here to educate you on how leaky ducts truly affect the efficiency of your AC.
This article will take a deeper look at how leaky ducts can drain energy, increase your bills, and affect your HVAC system’s overall performance.
Then, you’ll have insight into the crucial role your ductwork plays in the comfort of your home and can take the right steps to inspect and repair your leaky ducts.
6 HVAC Problems Caused By Leaky Ductwork
Leaky ducts and other ductwork problems can happen from a variety of causes, such as old age and improper installation.
When your ducts aren’t in the best shape, it decreases the efficiency of your entire HVAC system and its ability to properly heat and cool your home.
But…how?
Let’s look at the top six ways leaky ducts impact your HVAC system and your comfort.
1. Wasted Conditioned Air
When your HVAC system heats or cools the air, it relies on a closed system of ductwork to deliver that conditioned air to each room in your home.
If your ducts have leaks or cracks, some of this heated or cooled air escapes into your attic and walls.
This loss means that your HVAC system has to work harder to replace the lost air and keep your home at the desired temperature, consuming more energy than necessary.
According to the U.S. Environmental Protection Agency (EPA), 20-30% of conditioned air is lost due to leaks and holes in ductwork or poorly connected ducts.
Wasted conditioned air through your ductwork means your HVAC system needs more energy to cool or heat your home to the desired temperature – that’s wasted energy and money.
2. Increased Wear and Tear on Your HVAC System
Because conditioned air is escaping, the HVAC unit has to run longer and more frequently to compensate, putting more strain on your system.
Over time, this constant demand causes wear and tear on critical components, like the compressor, blower motor, and heat exchanger.
These parts wear out faster when they’re overworked, leading to frequent repairs and a shorter overall lifespan for your HVAC unit.
An HVAC system that doesn’t have to overcompensate for leaky ducts will last longer and require fewer repairs, saving you money in the long run and ensuring reliable heating and cooling year-round.
3. Higher Energy Bills
One of the most noticeable impacts of leaky ductwork is the increase in your monthly energy bills, as we touched on earlier in this article.
When your HVAC system works harder to replace lost air, it consumes more electricity or fuel, which directly translates to higher utility costs. You may not realize that your ductwork is leaking, but a sudden or consistent increase in energy bills can be an indicator that something is wrong.
By addressing leaky ducts, you can help your HVAC system operate more efficiently, leading to a significant reduction in energy costs. You will most likely even see a drop in your monthly bills after sealing, repairing, and insulating ductwork.
4. Decreased Indoor Air Quality (IAQ)
One of your HVAC’s main roles is to filter out the dust, dander, and allergens from your home to provide you with clean air and a healthy IAQ.
While the largest problem with leaky ductwork is air leakage, any openings in your ducts also allow dust, dander, debris, and insulation to infiltrate your conditioned air and circulate throughout your home.
This can lead to an increase in airborne allergens, dust, and even microbial growth, aggravating allergies, and respiratory issues.
Even if you have an indoor air quality (IAQ) system, it’s challenging to maintain clean, healthy air when leaks are introducing contaminants directly into your HVAC system. Properly sealed ducts keep unwanted particles out, ensuring your home’s air is clean and healthy to breathe.
5. Uneven Temperatures and Reduced Comfort
Leaky ducts also contribute to uneven temperatures throughout your home. Rooms farther from the HVAC unit may receive less conditioned air due to leaks, which results in hot or cold spots, depending on the season.
This uneven distribution of air can leave some rooms feeling too warm and others too cold, making it hard to maintain a comfortable environment.
With properly sealed ductwork, your HVAC system can deliver even airflow throughout the home and provide consistent comfort in every room without the constant need to adjust your thermostat or use portable fans and space heaters.
6. Environmental Impact
Leaky ducts don’t just affect your home—they also have a broader environmental impact.
When your HVAC system works harder to replace lost air, it consumes more energy, which often comes from fossil fuels. This increased energy usage contributes to higher greenhouse gas emissions.
By sealing leaky ducts and making your system more efficient, you’re able to save money while also reducing your carbon footprint and helping the environment.
What If I Have Leaky Ductwork?
If you’ve noticed higher energy bills, increased dust and allergens in the home, and an overall decrease in your HVAC efficiency, the culprit may lie within your ductwork.
Performing a visual inspection of your ductwork in your attic is the first step to see if your ductwork needs repair or a possible replacement.
Small cracks, holes, separation, or microbial growth around your ductwork indicate there is air leakage that affects your HVAC and your home’s comfort.
If you notice any damage or deterioration of your ducts, an expert HVAC company to professionally inspect and diagnose your issues will provide you with the proper solution to fix your ductwork and maintain the efficiency of your system.
How To Repair Leaky Ductwork and Improve HVAC System Efficiency
Now that you understand the six most common ways leaky ducts affect your system’s efficiency and compromise your home’s comfort and what to do about it, you want to know what the next steps are to repair your leaky ducts.
Allowing leaky ducts to exist in your home for even just a few years decreases the effectiveness of your heating and cooling system through
- Wasted conditioned air
- Increased wear and tear on your system
- Higher energy bills
- Decrease IAQ
- Uneven temperatures throughout the home
- Environmental impact
By understanding and addressing leaky ducts, you can significantly improve your HVAC system’s efficiency, reduce energy costs, and increase home comfort.
Regular ductwork inspections and maintenance are essential steps to ensure your entire system (HVAC and ductwork) works effectively as a unit, keeping your home comfortable and efficient all year round.
If you notice any signs of deterioration or leaks in your ductwork, it’s important to have them addressed as soon as possible by a professional to get your ductwork in tip-top shape to provide your HVAC and your home with proper air circulation and comfort.
Manually sealing ductwork is a simple and cost-effective way to seal ductwork. However, there is another option called Aeroseal, which is a duct sealant technology that seals your ducts from the inside and decreases the amount of air leakage through your ductwork.
Both types of duct sealant have their pros and cons, and one option may be better than the other, depending on your wants and goals for your duct repair.
