Ductwork Services in San Antonio, TX

High-Quality Ductwork Service in San Antonio

Your ductwork is an essential but often overlooked part of your HVAC system. Having the highest-quality heating and cooling system or one that is on its last legs doesn’t make a difference if your ductwork is damaged. Ductwork is located in the crawl space, attic, or both. Both of these areas are very isolated, making it incredibly easy for damaged ducts to go unnoticed.

For the best ductwork in San Antonio or the surrounding areas, look no further than our team at Damiani’s Comfort Design.

Signs It’s Time for Ductwork Replacement

  • Your ductwork is old – Ductwork parts, such as seals, seams, and joists, typically begin to fail 15 years after installation.
  • Your indoor air quality is poor – Ductwork expands and contracts throughout the seasons. Over time, this can cause your ducts to crack and lose air, inviting pollen, dust, and other allergens into your home.
  • You notice hot and cold spots in your home – Leaky ducts make it impossible to control the temperature in specific rooms.
  • Your energy bills are through the roof – ENERGY STAR® tells us that at least 30% of the air that runs through an air duct ends up leaking out.
  • You notice a moldy smell when you turn your HVAC system on – Damaged ductwork invites not only pollen but moisture into your home. This moisture can quickly become a breeding ground for mold.

How Do I Know When I Need Ductwork Reengineering?

It can be hard to tell when you need to retrofit your ductwork because you don’t see it all the time! This is why our team has compiled some of the most common signs that your ductwork isn’t keeping air flowing as best as it could be:

  • Your home has been getting pretty dusty – This might mean there are holes in your ductwork. Dust that usually stays up in your air ducts is now leaking into your home, which is not good!
  • Your HVAC system has become quite loud – This may mean your air ducts are too small for your HVAC system. If your ducts are imbalanced, you may need to get them reengineered by a professional to accommodate your HVAC unit.
  • You’ve been smelling some mildew – A wet, stinky smell could mean the worst. If your ducts aren’t insulated well, condensation could form and mold will arise! This is not good, so call a professional for ductwork retrofitting right away.
  • The temperature in your home hasn’t been consistent – Ah, yes, the telltale sign of a leaky duct system. Don’t deal with a too-warm or too-cold home anymore, and call Damiani’s for ductwork reengineering!

Frequently Asked Questions About Ductwork

Should ductwork be replaced after 20 years?

Ductwork is designed to last up to 15 years. The average life span of an HVAC system is 15 to 20 years, and as they age, they tend to get less efficient. If you’re replacing your HVAC system, it’s a good idea to replace the ductwork at the same time. By the time ductwork reaches the age of 15, it begins to deteriorate, which can also cause your HVAC system to be less efficient.  

Should I clean or replace my air ducts?

The Environmental Protection Agency reports the study of whether air duct cleaning is necessary is still in the early stages. It’s believed that most dirt in air ducts sticks to the ducts’ interior surfaces and doesn’t enter the living space. The agency does suggest having air ducts cleaned if there’s visible mold growth inside hard ducts or on other HVAC components, if the ducts are infested with vermin, or if they’re clogged with excessive dust and you notice it being discharged into your home. Some HVAC experts suggest having air ducts cleaned every three to five years, particularly if anyone in the house has respiratory problems. If your home’s air ducts are old, dirty, or damaged, it might be best to have them replaced.

How do I know if my air ducts are leaking?

There are some simple tests you can do to see if your HVAC ducts are leaking. A professional HVAC technician has advanced tools and skills to make a more accurate analysis. If you want to check yourself, start by visually inspecting all ductwork you can access. That’s typically your attic and basement or crawl space. Look for tears, gaps, and disconnections and check to see if there are sections where duct tape has been used. Duct tape does not properly seal ducts against leaks. Next, turn on your HVAC system and return to the areas you checked in the first step. Place your hand over the ductwork’s connections to see if you feel air coming out. Finally, with the HVAC system still running, run a smoke pencil or incense stick steadily over the ducts and watch to see if the ducts move.

How often do you need to replace ductwork?

The service life of ductwork can vary significantly under different circumstances. If your ductwork was installed properly, hasn’t been excessively exposed to corrosive elements, started with high-quality parts, and has been maintained over the years, it could conceivably last as long as 20 or 25 years before you absolutely need to replace it — but even in those circumstances, you’d see a loss in performance starting after its first decade. Without those excellent conditions, your ductwork’s more likely to need replacement at 15 or even 10 years from its initial installation if you want to maintain a high degree of performance and efficiency.

How much does it cost to install ductwork in an old house?

The cost of different installations can vary wildly with different circumstances, and your home being older is only one of many factors we’ll need to consider. If you have existing ductwork that’s adequate to your needs, and it’s been well-maintained without any problems along its route, then installing new ductwork in an older house isn’t particularly different from installing it in a new one. If, however, we need to consider architectural concerns, repair or reinforce structures, or work to gain access to the places ducts need to be run, then costs will increase accordingly. In some cases, it may be much more cost-effective to install ductless HVAC solutions based around a heat pump.

Can ductwork be repaired?

Generally speaking, yes: Ductwork can be repaired and sealed to improve its efficiency and restore performance — but only within certain limits. If your ductwork is leaking like a pasta strainer, then no amount of spot repairs will ever restore it to decent functionality. If, however, you just need to repair a damaged panel or a specific leaky corner, then our team can tackle that and get it back to near-peak performance in no time.
