Most of you know about the importance of maintaining your San Antonio properties in good condition. Still, you probably neglect the air ducts, an essential part of most HVAC systems. They are in charge of spreading conditioned air all over your house evenly. If the ductwork is damaged, the efficiency of the entire system will drop significantly.

If you do not maintain AC ducts properly, they will not work as effectively as they should. If you wait too long to make sure that the ductwork is working right, you may be paying for it down the road. As seen on this page, it is good to troubleshoot the problem before calling a professional AC repairer. Luckily, there are some minor repairs you can do yourself and thus save both time and money.

Leaky Duct

The best tip anyone can give you about AC ductwork is to inspect it regularly. You do not have to call an expert; you can simply look at the ducts on your own. Look for leaks, which will be pretty apparent, especially in places with visible signs of wear and tear. If you leave the leaks unattended, they will reflect on your monthly bills significantly.

Finding leaks is the hardest part. The rest of the repair is about applying the proper sealant or tape to the spots. Pay particular attention to joints and connections, where you can notice holes. Use metal duct tape, which is more durable than regular ones. Think of insulating exposed ducts. These are usually located in the attic or basement, making them a great ‘snack’ for small rodents. An extra layer of insulation will prevent these HVAC parts and do wonders for the system’s efficiency.

Fixing Galvanized Ducts

Unlike flex or fiberglass, metal sheet ducts are quite durable. These are not common in San Antonio, as they are mainly used in houses in colder areas. You will not have much trouble with burst pipes and leaks, but you frequently have to check joints and connections. Over time, the sealant on these places might lose. The heat will escape through these cracks. If this causes the leaky issue, you will only need some extra adhesive. In case of a larger gap, you might need to use duct mastic to seal the entire joint. Keep in mind that this product is intended for galvanized ducts only.

Torn or Rotten Ductwork

The insulation plays a significant role in the efficient operation of the ductwork. If it is damaged or worn out, conditioned air losses will occur. Also, condensation can occur in these places, which can further affect the cooling or heating of your home. The HVAC system has to work harder if the insulation is torn or missing. That will waste energy, and later on, money.

Insulation repair is another DIY task you can do without high costs. Once you locate the damaged spot, check the inner pipe condition. In case of any damage, repair it first. Then, add new fiberglass insulation into the hole and make sure it covers the entire repaired spot on the inner pipe. Cover the hole with foil and use insulation tape to seal up everything.


A dirty air duct is a breeding ground for harmful bacteria and mold that can make you and your loved ones sick. That is why regular ductwork cleaning and disinfecting are a must. It helps remove dust and dirt that collect around vents and enters the system.

It also helps to ensure there are no clogs in these lines. Dirt deposits, nested birds, or dead rodents can be a source of unpleasant smell that spreads around every time you turn the HVAC system on. Also, clogs can stop regular airflow and cause health problems for everyone in your home. These tips on fixing and repairing them are easy to follow. If you take a little bit of time to learn about your HVAC system, you will be able to keep your entire home cooler during the summer months and warmer during the winter. You do not have to call a professional to come and take care of the issue for you. If you have some skills in your hand, you can repair the issues on your own.
