How a Damaged Vapor Barrier Can Affect Your Utility Bills

How a Damaged Vapor Barrier Can Affect Your Utility Bills (and What to Do About It)

May 22, 20252 min read

When you think of high utility bills, you probably blame your AC unit, old insulation, or Arizona’s brutal summer heat. But one sneaky source of rising energy costs lies beneath your feet — a damaged or missing vapor barrier in your crawl space.

At Desert Mobile Home Services, we often find that mobile homeowners are unknowingly spending hundreds more per year because their crawl space isn't properly sealed. Let’s look at how this happens — and what you can do to fix it fast.

💨 How Vapor Barriers Help Control Energy Use

A vapor barrier is a thick plastic liner that sits on the ground under your mobile home. Its job is simple: block ground moisture from rising into your insulation and floor structure.

When that barrier is missing or damaged:

  • Moisture soaks your insulation, making it ineffective

  • Humidity rises, forcing your AC to work harder

  • Air ducts in the crawl space can rust or loosen, leaking treated air

  • Temperature regulation suffers, causing your HVAC to cycle constantly

The result? Sky-high energy bills and less comfort inside your home.


📉 How Much Can You Lose?

The U.S. Department of Energy estimates that crawl space inefficiency can increase energy costs by 15–25%.

For Arizona mobile homeowners spending $250–$400/month on cooling, that could mean $500 to $1,200 in annual losses — just from poor crawl space conditions.


🔎 What to Look For

You may need a vapor barrier repair or replacement if you notice:

  • Musty or damp smells inside the home

  • Floors that feel colder in winter or hotter in summer

  • Higher-than-average energy bills without a clear reason

  • Visible tears or missing sections of plastic beneath the home

  • Rusted or disconnected air ducts
