Aeroseal Duct Sealing Room

Comfort is More Than a Number on the Thermostat

Leaky ducts significantly contribute to the warmth and cooling of a home. Even the most energy-efficient heating and cooling systems cannot control the amount of comfort you experience in your living spaces if there are leaking ducts. The loss of cool and warm air to the wrong places inside, outside or in the unconditioned spaces of a home is significantly reduced with Aeroseal duct sealing because our patented sealing technology seals the ducts airtight. With Aeroseal, hard to heat or cool rooms will have even temperatures and will be more comfortable. Humidity levels are also easier to control after an Aeroseal.

Your Ducts Shouldn’t Cost You Money, But They Do!

Homeowners may not ever think about their air ducts. But the fact is, something that most of us never even think about could be costing us a lot more money than we realize.

Whether a home is old or new, leaking ducts cost a homeowner money, not to mention the stress it causes an HVAC system. Consider this:

  • About 50% of the average home’s utility bill is spent on heating and air conditioning.
  • On average, 30 cents of every $1 spent on heating and cooling a home disappears into thin air due to leaky ducts.
  • 25% to 60% of heated and cooled air leaks doesn’t make it to their intended rooms.*
  • Duct leakage in homes costs homeowners $25 billion a year in utility costs.


Create a Safer, Healthier Home

  • Leaks pull mold, dust and other pollutants into your home causing indoor air quality issues and have potential to create harmful allergy problems.
  • Leaks contribute to safety issues related to backdraft of appliance fumes, auto exhaust and radon gases being released into your home.

How Does Aeroseal Duct Sealing Work?

With air ducts often tucked into ceilings, walls, attics, and basements, the system can be difficult to access. Locating and addressing leaks one by one is time-consuming, inefficient, and ineffective. Without the proper training and tools, ductwork can easily be damaged.

Instead of relying on imperfect and outdated methods, Sanford Temperature Control offers our customers cutting-edge technology. With Aeroseal Duct Sealing, we cut down on time and expense, avoid mess, and successfully eliminate up to 90% of air leakage.

Using a computer-guided procedure, airborne adhesive particles are blown into ductwork, sealing cracks, holes, and imperfections that allow air to escape, while filling openings up to one inch in diameter.

Aeroseal lowers energy bills, prevents fumes and odors, creates healthier indoor air quality, and enhances comfort by maximizing airflow. The process also reduces the workload on your HVAC system, so you can expect fewer repairs, less maintenance, and longer service life.
