Blown-In Fiberglass and Cellulose
Attic Insulation in Phoenix, AZ
Stop paying to cool your attic. Insulate it right and feel the difference upstairs.
Blown-in attic insulation and old insulation removal for Phoenix-area homes.
In a Phoenix summer your attic can pass 150 degrees, and thin insulation lets that heat sink straight through the ceiling. Legendary Energy blows in fiberglass or cellulose to the R-30 to R-60 range the U.S. Department of Energy recommends for our climate, removes damaged insulation when needed and checks your ducts and AC while we are up there. The result is cooler ceilings, a quieter AC and steadier temperatures from Sunnyslope to Ahwatukee. Call today and book your attic check.

Heat comes from above
Most of the heat that gets into a Phoenix home in summer comes through the roof and attic. If your insulation is thin, settled or damaged, your AC is fighting the sun all afternoon.
Blown-in insulation fixes that. It fills the gaps around joists, wires and pipes that rolled batts leave open, so heat has no easy path down. We measure what you have, recommend the right material and depth, and blow it in evenly.
Upstairs too hot to sleep? Call (602) 266-9566 and we will check your attic.
Highly recommended and professional work. Victor can be trusted to do the work. He has repaired my a/c unit, removed old insulation, installed new insulation and repaired the thermostat wire.

Summer and winter
Insulation Works Every Month of the Year
In summer, attic insulation keeps roof heat out of the living space so your AC runs less. In winter, the same layer keeps furnace or heat pump warmth from escaping through the ceiling.
It also cuts down on dust and outside noise coming through the ceiling, which homeowners notice right away.

Batts or blown-in?
Why Blown-In Beats Rolled Batts in Most Attics
Batts can work in a brand-new, wide-open attic. In most existing Phoenix attics, blown-in insulation simply covers better.
Blown-in insulation
- Fills around joists, wires and pipes
- Covers the attic floor evenly
- Easy to top up later
- Fast to install in tight attics
Rolled batts
- Leave seams and voids
- Compress around obstacles
- Slow to fit in low spaces
- Gaps let heat through

FAQ
Attic Insulation Questions
How much attic insulation do I need in Phoenix?
The U.S. Department of Energy recommends R-30 to R-60 for attics in our climate. We measure what you have and tell you how much to add.
Is cellulose safe in an Arizona attic?
Yes. It is treated with borate, which helps it resist fire, insects and mold. It must stay dry, so we check for roof leaks first.
Is blown-in better than batts?
In most attics, yes. Blown-in fills gaps around joists, wires and pipes, while batts leave seams and voids where heat gets through.
Do you remove old insulation?
Yes, when it is damaged, wet, contaminated or full of debris, so the new insulation starts on a clean attic floor.
Does attic insulation help in winter?
Yes. It keeps heat from escaping through the ceiling, so your furnace or heat pump runs less on cold nights.
How long does the job take?
Most attics take one day. We give you the schedule with your quote.
