Is your home's air conditioning system not performing like it used to? Are you noticing uneven temperatures, dusty air, or skyrocketing energy bills in your home? One reason may be because there’s an issue within your air conditioning ductwork. Don't sweat it!
This comprehensive guide will walk you through everything you need to know about air conditioning ductwork repair.
Here are some potential common causes of damage to AC ductwork.
If the damage is minor, you can attempt these DIY fixes: Please note that we also always recommend calling a professional first - this information serves for educational purposes only.
Identify leaks by feeling for escaping air or using a smoke test. Seal small gaps or holes with mastic sealant or aluminum foil tape (not regular duct tape, as it degrades over time).
If a duct has become disconnected, secure it back in place using screws and duct sealant to ensure an airtight fit.
If ducts run through unconditioned spaces, wrap them with duct insulation to prevent energy loss.
Use HVAC-approved metal tape or mesh tape along with mastic sealant to cover minor punctures.
Remove dust buildup using a vacuum with a long hose or a soft brush to improve airflow and air quality.
But, what if the damage persists even after your DIY efforts to fix the AC ductwork? This is your cue to call professionals before the damage worsens.
The first step in any AC duct repair is a thorough inspection. HVAC professionals use specialized tools, including cameras and pressure tests, to check for leaks, blockages, or poor insulation. They also assess airflow efficiency to identify any hidden issues that might be affecting your system’s performance.
Leaky ducts are a common issue that can waste a significant amount of energy. Professionals use mastic sealant, metal tape, or aerosol-based duct sealant to close gaps and prevent air from escaping. Proper sealing improves efficiency and enhances indoor air quality by preventing dust and pollutants from entering the duct system.
If the ductwork has major cracks, rust, or holes, technicians may need to repair or replace sections of it. They cut out damaged parts and install new duct segments, ensuring a tight and secure fit to prevent future issues.
Proper insulation helps maintain cool air temperature and prevents energy loss. HVAC experts wrap ducts with high-quality insulation material to enhance efficiency, particularly in unconditioned spaces like attics or crawl spaces.
Ducts can accumulate dust, debris, and even mold over time. If airflow is restricted, professionals clean the ductwork using powerful vacuums and brushes to remove contaminants, improving air quality and system efficiency.
Once repairs are complete, technicians test the system to ensure even airflow distribution. They may adjust dampers and vents to balance air delivery, ensuring every room in your home receives consistent cooling.
Finally, HVAC experts perform a final assessment using airflow meters and thermal imaging to confirm that the ductwork is sealed, clean, and operating at peak efficiency. They also check for proper air pressure and temperature consistency throughout the home.
If you notice uneven cooling, rising energy bills, strange noises, or excessive dust in your home, it may be time to have your AC ductwork inspected and repaired. Hiring a professional ensures that the job is done correctly, saving you money and improving comfort in the long run.
