Ductwork is complex: it isn’t very visible, it can snake through walls and crawl spaces, and it can be difficult to access. It’s these factors, plus a true understanding of how to work on ducts, that makes it important you hire a professional for your duct sealing service in Lake Worth. Since 1986, Astro Air Inc. has been serving the Lake Worth and surrounding communities, and we have seen first-hand how duct sealing can help you and your air conditioning system.
Benefits of Duct Sealing
There are several ways in which duct sealing can help you and your air conditioner:
- Better energy efficiency – over time, your ductwork can develop holes, cracks and broken seals, or disconnect from other sections. These types of gaps can cause air loss in your system, for which your air conditioner has to compensate. Any time your air conditioner needs to work harder, it uses more energy, which reduces its energy efficiency.
- Better indoor air quality – openings in your ductwork can allow moisture, dust, dirt and other fumes and particles directly into your air stream. Sealing the ducts eliminates this, improving you the quality of your indoor air.
- Better comfort – air loss in vents means less cooling is getting into your home, oftentimes leading to uneven cooling. When your air ducts are sealed, your air gets delivered in its entirety, leading to better comfort.
How Do Professionals Seal Ducts?
Here is a quick overview of how ducts are sealed by a trained technician:
- Ends of the ducts are cleaned to help the sealant bond correctly.
- The technician will brush mastic (a fibrous sealant) over the area to be repaired.
- The technician will place fiberglass or foil tape over the mastic. Important note: never use duct tape to seal ducts. Duct tape, and any other tape, usually doesn’t stick and will degrade quickly.
- A second coating of mastic will be added over the tape.
- The mastic needs time to cure in order to harden properly, so it is left alone.
- The technician will continue this process until all holes and cracks are repaired. To seal connections, he/she will use a metal binder and sheet metal nails to bind 2 sections together.
Typically, your technician will start at the indoor unit and work to the furthest register in your home. This is because there is higher pressure nearer to the indoor unit.
