Common Tools Used in Duct Repair

To protect the integrity of the ductwork in your home, you will occasionally need to schedule repair work on the ventilation system. Leaking ducts will cause a drop in air pressure, leading to a loss of heating and cooling and a drain on power, and will also result in the infiltration of dust, dirt, and other contaminants into the ventilation system. With the help of professional duct repair in Atlanta, GA from the skilled team at Comfort Zone Heating & Air, you can have your ductwork restored to airtight condition.

When you suspect that you are losing air pressure from your ducts, call us first for testing to see where you will need sealing. After a thorough inspection, we’ll use the best tools available to repair your ducts.

Here Are Some of the Tools We use on duct repair

  • Duct leak tester: This is an essential tool for locating where repair needs are necessary in the first place. The technicians turn on your HVAC system and check along the ducts with this device, which consists of a fan and a pressure sensor. The leak tester will find where air pressure is escaping from the ducts and how much. This will tell the technicians where to target their repairs and what methods will work.
  • Mastic sealant: This is a common way of sealing up breaches and holes along ducts. Mastic is a resin-based sealant that dries fast but remains flexible so that it won’t crack because of the ducts moving due to changes in temperature. The smooth finish of mastic also means there is less air resistance. Duct repair technicians apply mastic using a special caulking gun.
  • Metallic tape: Some duct repair specialists prefer using metallic tape (the true “duct tape”; cloth-backed “duct tape” is not actually for ducts) over mastic sealant because it creates an actual mechanical seal. Metallic tapes are durable and will last for many years, and have high resistance to the temperature extremes inside the ventilation system.

In cases of extremely old ductwork, repairs may have to be more extensive and involve replacing sections of the ducts with new ones. If you are experiencing a general drop in efficiency in your HVAC system, you may need to have duct replacement work done. Ask the specialists after they perform testing what your best options are.

Comfort Zone Heating & Air is available for all your ventilation needs, any time of the day or night. Contact us today for duct repair in Atlanta, GA, as well as duct replacement and insulation services.
