The Most Overlooked Entry Point in Your Home

Why AC Chases Are Such a Big Problem

An AC chase is basically a built-in tunnel. Here’s why wildlife loves it:

• Perfect Size: Rats and mice only need about ½ inch to squeeze in. Most chases are much bigger.
  
  
• Low to the Ground: Easy access — no roof climbing required.
  
  
• Hidden Behind Bushes: Homeowners rarely check them. Critters check them constantly.
  
  
• Direct Path Inside: Once inside the chase, they can climb straight into the attic or walls.
  
  

To a rodent, this isn’t “a gap.”
It’s a front door.

What Happens Once Animals Get In

We see the same issues over and over again:

• Chewed AC insulation
  
  
• Droppings piled up along the chase
  
  
• Scratching behind walls
  
  
• Torn attic insulation
  
  
• Urine soaked into the wood
  
  
• Chewed electrical lines near the air handler
  
  

By the time you hear them, they’ve already done damage.

Why DIY Foam Doesn’t Work

A lot of people try to fix this with spray foam, but here’s the truth:

Rodents chew foam like it’s a snack.
We see failed foam jobs every single week.

If you’re going to seal the AC chase, it needs to be done with chew-proof materials, not patchwork filler.

How We Seal AC Chases for Good

At Homeland Wildlife & Pest Control, AC chases are always on our inspection checklist.
Here’s what we do:

• Find every gap — even ones tucked behind plants or pipes
  
  
• Seal it with metal or chew-proof materials
  
  
• Blend and secure it cleanly
  
  
• Inspect surrounding entry points (cracks, siding gaps, weep holes, roof returns)
  
  
• Back the work with a lifetime warranty
  
  

Once we seal an AC chase, nothing is getting in that way again.

Take Five Minutes Today

Seriously — walk outside and check your AC lines.
If you can see daylight, insulation, or a hole around the pipe, animals already know about it.

A quick fix now can prevent hundreds (or thousands) in attic repairs later.
