For the hot and humid summers that San Marcos faces (along with its mild winters), your homes and commercial buildings need AC systems that can keep up.

Air conditioners and ductwork go hand in hand. The indoor air quality and comfort level of your home and/or business depends on both the HVAC unit and the air ducts. 

Wondering whether you should upgrade your ductwork along with your new AC? We’ve put together some information to help you answer this question:


Why Should You Replace Your Ductwork?

With any building upgrade, you have to wonder if it’ll be worth your money. Here’s how new ductwork can improve your home and/or business:

  • New ductwork is more energy-efficient.

Spending money on new ductwork can actually help you save on your monthly utility bills. Your air conditioner won’t need to work as hard to cool your home/business, thanks to a system of brand new air ducts. The AC will use less energy, which will save you money on your monthly electricity bill.

In turn, this can extend the lifespan of your AC. Faulty ductwork will make the system work harder to control the temperature, which puts additional strain on its components.

  • You’ll get the most out of your new AC.

Investing in a new HVAC unit brings a significant cost to home and commercial building owners. You want to make sure that your hard-earned money is well spent. 

Your HVAC system will operate at maximum efficiency when it works in conjunction with leak-free ductwork. 

  • Your home or commercial building will be more comfortable.

We’ve all dealt with a home that’s sweltering in one room, and freezing in another. 

In the workplace, the temperature of offices and boardrooms can directly affect productivity. Your staff members will have a harder time focusing on their work when they’re distracted by the stifling hot air.

But with new ductwork, your air conditioner will have a much easier time regulating temperatures in your home and/or workplace.


Signs That Your Ductwork Needs To Be Replaced

If you notice any of these issues, then it might be time for a ductwork upgrade: 

  • It’s nearing the end of its lifespan.

When you take a whiff of last month’s milk in the fridge, you know when it’s gone sour. However, it isn’t so easy to tell with ductwork.

Like most appliances and systems, ductwork only lasts so long. After enough years of use, it starts to break down. The average lifespan of a ductwork system is 20-25 years

Find out when your ductwork was originally installed. If it’s older than 15 years, then it’s likely that the quality has deteriorated over time. The airflow might be restricted by dust and debris. Consider upgrading your ductwork along with your AC if it’s past its prime.

  • You notice a strange odor. 

Have you noticed a smell that just isn’t right in your home? No matter how much you scrub your walls or vacuum the carpets, that musty odor remains. The culprit could be your ductwork.

The cool, relieving air from your new AC unit will be spoiled by moldy ductwork. Rather than enjoying the comfortable temperature of your home, you’ll be put off by the strange scent that accompanies it.

  • The ducts are leaking.

When your ductwork leaks the air that your air conditioner works so hard to cool, you’ll notice it in your monthly bills and the comfort levels of your home.

It’s estimated that most homes lose 20-30% of their air due to leaky ductwork. Not only is this a wasteful use of energy, but it’s an expensive one, too. Brand new ductwork won’t have any leaks or blockages, so you won’t have to worry about inefficiencies.


So, should you replace your ductwork, or let your new air conditioner do the job? The answer depends on the age and performance of your ducts. They might need a quick tune-up to restore their functionality.
