Living in Arizona means battling extreme heat for much of the year—and if your home’s insulation isn’t up to the task, your comfort and energy bills will suffer. Knowing when to replace insulation can save you money and improve indoor comfort, especially during those scorching summer months.
Here are the top signs your home may have poor insulation and what to do about it.
1. Your Energy Bills Keep Rising
If your APS or SRP bills seem higher every year—even with the same AC usage—your insulation may be the culprit.
Poor insulation allows conditioned air to escape and hot air to creep in, making your HVAC system work overtime.
A quick attic inspection by a professional can reveal if your insulation is underperforming or outdated.

2. Uneven Temperatures Between Rooms
Do some rooms in your home stay cool while others feel like a sauna?
Inconsistent temperatures are a classic sign of poor insulation.
Arizona homes, especially older ones, often lack adequate coverage in attics, walls, or ductwork, leading to hot spots and uneven cooling.
3. Hot Walls or Ceilings
Touch the interior walls or ceiling—if they’re hot to the touch during the day, heat is likely penetrating through poorly insulated spaces.
Quality insulation acts as a thermal barrier. If that barrier is missing or has settled over time, it’s time to consider a replacement.
4. Old Insulation Has Settled
Many Arizona homes have insulation that’s settled over the years, reducing its effectiveness.
Most homes only need about 7 inches of new blown-in insulation added on top of the old layer to reach optimal performance. We use a high-performance, enhanced blown-in insulation that won’t settle over time—unlike traditional fiberglass.
Plus, we install ruler markers in your attic, so you can visually confirm the insulation depth at any time.
Upgrade Once. See the Results for Years.
Our enhanced blown-in insulation won’t settle—and with attic rulers installed, you’ll always know your insulation is holding strong.

5. Drafts and Air Leaks
If you feel drafts near windows, doors, or baseboards—especially during monsoon season or desert nights—poor air sealing and inadequate insulation are likely to blame.
Proper attic insulation can help keep indoor temps stable year-round.
6. Your Home Was Built Before 2000
If your Arizona home is more than 20 years old, chances are it has outdated insulation that no longer meets today’s efficiency standards.
A modern upgrade can make a major difference in both comfort and monthly cooling costs.
