Cleaner air and tighter ducts

Dust, smoke season and leaky ducts all show up in the air you breathe. We offer filtration, humidity control and Aeroseal duct sealing to fix the cause, not just the symptom.

What we do

Signs your indoor air needs attention

Not sure? Call (509) 586-9464 and describe what’s happening.

  • Dust that comes back days after cleaning
  • Rooms that are stuffy or uneven from one end of the house to the other
  • Dry skin, static and cracked wood floors in winter
  • Smoke or allergy symptoms that ease when you leave the house
  • Filters that clog much faster than they should

How Aeroseal works

Aeroseal blows a sealant mist through your ductwork while it’s pressurized. The particles collect at the leaks and seal them from the inside, including leaks behind walls and ceilings that can’t be reached by hand.

The system measures leakage before and after, so you can see the result.

Installed the Dayco Way

Every system we install is done so that anyone at Dayco can recognize it was installed properly: safely, to the manufacturer’s specifications and running at its best efficiency.

Afterward, a maintenance plan keeps it that way, from $18 a month.Compare plans
