Air Duct Repair

We Fix Ducts To Improve Efficiency

Central heat and air relies on ducts to provide a consistent temperature all throughout your Hays County house. But if yours are compromised and are in need of air duct repair, you might notice several signs, such as:

  • Abnormally high utility bills in winter and summer.
  • Visible kinks in the ductwork.
  • Difficulty heating and cooling despite adjusting the thermostat.

Ducts that are at risk for holes and tears include ducts that are:

  • Older.
  • Located “out of the way” in crawlspaces or attics.
  • Improperly installed from a disreputable company.
  • Self-repaired with duct tape or improper sealant.

Garner's air duct repair and sealing service will take these problems off your hands and transform your ducts into perfectly secure air tunnels.

How do you fix a torn air duct?

Yes, flexible ductwork can benefit from repairs. Add a hanger strap next to the slipping connection to fix the loose collar on the flexible duct and release any tension. Add more hanging straps all the way along the duct run. Using pliers or wire cutters, cut the duct strap. Remove the insulation from the connection by pulling it. To ensure that the insulation is properly covered, adjust the outer liner. On the butt edge of the outer layer, apply mastic. When the mastic has sealed the connection, slide the connection together and mash the materials together; then, secure it with a duct strap. Apply mastic to the joint's exterior.

A slightly different process is used for sheet metal ducting. The hanging straps or brackets on either side of the repair area should first be loosened. To inspect the leaking joint, sufficiently lower the duct. This kind of leak typically only requires additional sealant, but large gaps should be fully exposed and examined. Take the joint apart and reconnect it properly if the large gap was caused by a missing or improperly installed S-lock.

Can you patch HVAC ductwork?

Yes, in some circumstances it is possible. For this process, the hole does indeed need to be smaller. Your ductwork's entire perimeter should first be thoroughly cleaned with soapy water, followed by a thorough rinse and complete drying. After that, you can use Underwriters Laboratory (UL) 181 foil-backed tape to seal the duct hole. High temperatures can be tolerated when using this tape. Any tape that has not been authorized for use on ductwork presents a risk of fire and smoke.

How long does it take to fix leaky air duct?

The amount of time needed to fix a leaky air duct depends on how accessible it is, how much damage it has, and how difficult the repair is. Small leaks can be fixed quickly in a few hours, while major ducting replacements or repairs can take a day or more. HVAC specialists assess the problem, determine the best course of action, and project the repair time based on the particulars of the ducting problem.

How many types of air ducts are there and what are they?

Air ducts come in several types, including:

  1. Flexible ducts: Made of plastic or metal wire coil, flexible ducts offer versatility and easy installation.
  2. Sheet metal ducts: Constructed from galvanized steel sheets, these ducts are durable and commonly used in residential and commercial buildings.
  3. Fiberglass duct board: Insulated ductwork comprising fiberglass sandwiched between layers of sheet material.
  4. PVC ducts: Crafted from polyvinyl chloride, PVC ducts are corrosion-resistant and often used in industrial settings.
