Large Duct Air Conditioning for Older Homes

Find Out More from Our St. Paul HVAC Experts

If you own an older home that wasn’t designed with central air conditioning in mind, retrofitting air conditioning can be tricky. However, if you have the wall and ceiling space to install air ducts, retrofitting an in-home HVAC system may be a viable option.

Advantages of Large-Duct HVAC Systems

Older homes that weren’t designed with traditional cooling systems in mind may still have enough space to install a duct network. For those who don’t want to have to deal with large, bulky boxes mounted on their walls, this is the ideal choice. A central air conditioning system delivers the air through a small, discreet vent that can often be blended seamlessly into your décor; ductless systems often don’t have that ability.

Here’s why you should install a traditional large-duct HVAC system in your older home, if possible:

  • They’re affordable
  • They’re reliable
  • They’re quiet
  • They don’t leave large, bulky boxes on your wall
  • They have the power to cool your entire home, including large rooms

Of course, there are trade-offs to these systems. They do require additional maintenance compared to other systems, and it’s strongly advised you have them inspected and maintained at least once a year by a St. Paul air conditioning professional. They also take more time to install, as the larger ducts take a good amount of work to put in place.

When you’re considering installing an air conditioning solution for your older or historic home, it’s strongly advised you review your options with a local air conditioning expert. They can tell you whether or not you have the space to install large air ducts, or if you may be limited to small duct systems or ductless installations based on the size of your walls and ceilings.

Frequently Asked Questions

How much does it cost to replace AC ductwork?

It’s hard to give a single answer for the cost of replacing ductwork, because many different factors go into the final price. The difficulty of accessing your existing ductwork to remove it, the sheer labor involved in doing so, the cost for materials and products for the new ducts you want installed, and the difficulty of the labor for the actual installation all come together to determine the final price tag on ductwork replacement. Consider each of these factors, and realize that all of them will also be multiplied by the sheer amount of ductwork necessary for your home based on its size.

Should ductwork be replaced after 20 years?

Thermal stress and vibration over 20 years, combined with the fact that most homeowners do little to no maintenance of their ductwork, make it extremely likely your ductwork has degraded after two decades, even if it’s not necessarily a guaranteed problem. There’s also the consideration that best practices for ductwork installation have come a long way over 20 years, meaning that if you’re unlucky, your ducts might be heavy with an inefficient design that wastes energy — even if there are no leaks or other problems from degradation, you might be wasting power on twisting, turning ducts to no benefit. All that to say: Even if you don’t need to replace your ductwork, doing so can reap big benefits.

Can you oversize an AC unit?

Yes, it’s possible for an AC unit to be oversized. An air conditioner that is too large for the amount of air you need to cool is much more likely to create cold spots, or hot spots if you cut it off in response to cold spots. It may also be less comfortable, because it won’t run long enough to dehumidify your air the way an appropriately sized air conditioner does — meaning your air will be cold, but humid. This often results in an unpleasant clammy feeling to the air. Finally, a large unit will be prone to short, inefficient on-and-off cycles; a well-sized air conditioner runs for a decent length of time, hitting peak efficiency before it cuts off for a while. Turning on and off frequently is bad for your system and will waste energy.
