Aeroseal Duct Sealing

Proper Duct Sealing with Aeroseal

We can all see a water leak, but air leaks are not so easy to spot. Leaking ducts could be COSTING you HUNDREDS of DOLLARS every year on your home energy bills. Both in gas to heat your house and electrical to run your furnace fan. If you have central air conditioning, your furnace fan has to run year round thru your LEAKING DUCT WORK not just during the heating season, but during the hot summer months as well.

It is not uncommon for us to find a house where the furnace ducts are LEAKING 20% to 30% or more of the total air volume from the furnace thru all the small unsealed openings in the air ducts. This means that your furnace has to run 20% to 30% longer to get the conditioned air to the livable space it was intended for in your home.

Imagine saving 20% to 30% off LAST YEARS HEATING BILLS!

Some people try to seal their duct work with duct tape. Trying to duct tape the joints is at best a band aid effect, the tape eventually dries out and no longer seals the leak.

When air ducts are sealed with a mastic type sealer the mastic often shrinks as it dry’s, eventually cracking and not sealing to an effective level. HVAC contractors often seal what they can see, and leave all of the unseen joints that you cannot see not properly sealed. Often, some of the duct is inaccessible because its located above a ceiling or in a wall cavity, impossible to seal until now!

AEROSEAL DUCT SEALING METHOD from the inside is the most cost effective method of sealing furnace ducts. ALL DUCT WORK from your furnace to the furthest floor grill is sealed from the inside, even the ductwork above finished ceilings or in a wall cavities can be sealed FROM THE INSIDE.

At Kesil Test and Balance we first start by pressure testing your duct work before we begin the sealing process. Our computer software will record the volume of air leakage from your duct work. We will then start the sealing process with the HOME SEAL EQUIPMENT and seal your ductwork from the inside. After the sealing process the computer software measures the final air leakage, compares it to the first level and prints a DUCT SEALED REPORT showing the substantial reduction in air leakage. As well this method of duct sealing is guaranteed for 10 years.

Aeroseal Duct Sealing Process

The duct sealing process is surprisingly quick and easy
  • Preseal test to measure the leakage as a baseline for measuring progress.
  • Block off the registers with foam or plastic.
  • Inject an UL tested and approved aerosol into the duct system.
  • Since the air has no place to go except out through the leaks (the registers are blocked), the sealant material is deposited precisely at the air duct holes or cracks where leakage occurs.
  • Computerized sensors are used to measure and control the progress.
  • Postseal test to measure improvements.
  • Complete report and certificate printed on the spot to provide a record of improvements.
