Should You Upgrade Old Ductwork with Your New Furnace or A/C?
Upgrading your furnace or air conditioner is a significant investment, but it’s not the only piece of your home’s comfort puzzle. If your ductwork is outdated, leaky, or poorly designed, it can keep even the most advanced HVAC system from working efficiently. So, when it’s time to install a new furnace or A/C, it’s worth asking: Should you also upgrade your ductwork?
Here’s what you need to know before making a decision.

Old Ductwork Can Waste Energy
Over time, ducts can develop leaks, gaps, or disconnections that allow conditioned air to escape into walls or crawl spaces. In fact, the U.S. Department of Energy estimates that up to 30% of airflow can be lost in homes with leaky ducts. That means your new furnace or A/C has to work harder, and you’ll pay more in energy bills.
Tip: If your ductwork is more than 20 years old, it may be time to replace or reseal it. Contact H&S today to discuss duct repair or replacement.
New HVAC Systems Need Proper Airflow
Modern high-efficiency furnaces and air conditioners are designed to deliver optimal performance under specific airflow conditions. If your existing duct system is too small, too large, or poorly laid out, your new unit may not run as efficiently, or could even experience premature wear.
A mismatch between the system and ducts can also reduce comfort, with hot or cold spots throughout your home.
Air Quality Depends On Duct Condition
Dust, mold, or debris in your ducts can circulate through your home every time the system turns on. If you’ve noticed more allergy symptoms, visible dust, or musty odors, your ductwork could be the cause.
When installing a new HVAC system, it’s a good opportunity to inspect, clean, or replace ductwork to improve indoor air quality.
Get the Most Out of Your New System
You’re investing in a new furnace or air conditioner to enhance comfort, reduce your energy bills, and increase reliability. If your ductwork isn’t up to par, you won’t get the full benefit of your new system.
Upgrading ducts simultaneously means your entire HVAC system works together—from the blower to the vents—for maximum efficiency and performance.
It’s Easier and Cheaper to Do It All At Once
If your ductwork needs to be replaced, doing it at the same time as your new system installation can save time, money, and hassle. Technicians are already on-site, which avoids the need to tear into ceilings or walls a second time.
Bonus: Some energy rebates and financing programs are available for full-system upgrades, including ductwork.
