ATTIC INSULATION
FOR ARIZONA HOMES
Most West Valley homes built before 2005 have R-19 to R-25 insulation — Arizona Energy Star recommends R-49 to R-60. Upgrading your attic insulation is the single highest-ROI home improvement for reducing AC costs in Arizona.
Bradford is an HVAC company, not an insulation contractor. We're evaluating a partnership with a licensed insulation contractor to offer this as a home cooling efficiency package. Use the form below to express interest — we'll connect you with a vetted contractor.
WHY ATTIC INSULATION IS AN HVAC ISSUE
What Bradford Sees in West Valley Attics
Bradford technicians go into attics on nearly every HVAC service call. The most common finding in homes built before 2005: inadequate insulation. Many homes have 3–4 inches of blown-in fiberglass (R-11 to R-15) — less than a third of what Arizona Energy Star recommends.
When Ken sees inadequate insulation, he tells the homeowner. The connection is direct: if your attic is poorly insulated, your AC works harder, your energy bills are higher, and your system wears out faster. Fixing the insulation is often the most cost-effective HVAC "upgrade" available.
INSULATION OPTIONS FOR ARIZONA HOMES
Blown-In Fiberglass
$1,000–$2,000
Target: R-49 top-up
The most common and cost-effective option. Blown over existing insulation to bring it up to R-49. Fast installation (1–2 hours for most homes). No removal of existing insulation needed.
- Most affordable
- Fast installation
- Works over existing insulation
- No mess or disruption
Blown-In Cellulose
$1,200–$2,500
Target: R-49 top-up
Made from recycled paper, cellulose provides slightly better air sealing than fiberglass. Good choice for older homes with more air leakage. Fire-retardant treated.
- Better air sealing
- Eco-friendly (recycled)
- Good for older homes
- Fire resistant
Radiant Barrier + Insulation
$1,500–$3,500
Target: R-49 + radiant barrier
Reflective foil installed in rafters plus blown-in insulation below. Reduces attic temperature by 20–30°F before heat reaches the insulation layer. Best ROI in Arizona's high-sun climate.
- Reduces attic temp 20–30°F
- 5–10% additional energy savings
- Best for dark or west-facing roofs
- Combines two solutions
