5 Best Attic Insulation Companies in Phoenix for a Cooler Home
My HVAC is already working overtime, and a poorly insulated attic isn’t exactly helping. In Phoenix, that’s basically asking your cooling system to fight the sun with one hand tied.
Good attic insulation helps keep that brutal roof heat from creeping into every room. It can ease the load on your AC and make summer power bills a little less terrifying.
So, I looked for the best attic insulation in Phoenix to help homes stay cooler without making the AC do all the heavy lifting. These local contractors stood out for insulation, sealing, and keeping desert heat where it belongs.
How much does attic insulation cost in Phoenix?
Attic insulation in Phoenix typically costs around $1.50 to $7.00 per square foot. For a 1,500-square-foot attic, many projects land between $2,000 and $6,000, though premium materials can cost more.
Blown-in fiberglass and cellulose are among the more affordable options. Both usually run about $1.50 to $3.50 per square foot, or roughly $2,250 to $5,250 for 1,500 square feet.
Open-cell spray foam costs about $3.00 to $5.00 per square foot. A 1,500-square-foot installation may total around $4,500 to $7,500.
Closed-cell spray foam is the priciest option here. Expect about $4.00 to $7.00 per square foot, or roughly $6,000 to $10,500 for 1,500 square feet.
1. Phoenix Family Insulation
Address: 2325 E Camelback Rd #400
Contact: (602) 536-8798
Hours: Monday-Saturday, 8 AM – 5:30 PM
Phoenix Family Insulation feels like a practical pick when your attic’s turning into a heat trap. They work with blown-in fiberglass, batt insulation, radiant barriers, and insulation removal for older material.
I like that you’re not boxed into one insulation type from the start. Their Phoenix-area coverage is broad too, which is handy if you’re elsewhere in the Valley.
They offer free estimates, so you can get a better idea of what your attic actually needs before committing.
Customer feedback frequently mentions responsive service, punctual crews, and tidy work.
The main drawback is that there’s no standard pricing to refer to. You’ll need to request a quote before you can properly compare costs with other Phoenix insulation companies.
Customer Reviews
Friendly, efficient
Phoenix Family Insulation just upgraded the insulation in our attic which was severely needed. They were highly recommended to us and their quote was about half the other quotes we received. Nick, the owner, and his crew were quickly responsive, friendly, efficient and cleaned up beautifully after themselves. We are very happy we choose Phoenix Family Insulation!

2. Phoenix Insulation LLC
Address: 3102 W Lewis Ave Suite 7
Contact: (602) 419-0270
Hours: Monday-Saturday, 7 AM – 5:30 PM
Phoenix Insulation LLC is a solid option if your attic feels more like an oven than storage space. They handle spray foam insulation for homes, warehouses, offices, and other commercial properties.
I like that their services aren’t limited to one type of project. They work on both new construction and retrofits, so older Phoenix homes aren’t left sweating it out.
Free estimates make it easier to size up the job before committing. Customer feedback frequently mentions punctual crews, tidy work, and noticeable improvements after installation.
The main drawback is that standard pricing isn’t easy to use for canvassing. You’ll need to request a quote before comparing costs with other Phoenix insulation contractors.
Customer Reviews
I am very happy with the work that was done
I mostly corresponded with Orlando. He communicated well and even reminded me that they would be at my house the next morning at 7 AM. They arrived promptly and were hard at work. They did blown-in fiberglass insulation and let me know which areas of the attic needed extra attention. I price-checked four other companies and they were the least expensive. They were professional and did a great job. I am very happy with the work that was done!

You will be happy
Only GREAT things to say about working with Phoenix Insulation!! Mario was responsive and super nice. He explained the current state of the attic and pointed out things even the home inspector didn’t notice or tell us about. Mario and his team completed the job in only an hour, and I am really impressed. The price was super reasonable and I couldn’t have asked for a better experience. I will be recommending them to all of my friends!! Definitely go with Phoenix Insulation & you will be happy 😁

3. Attic Construction
Address: 4014 E Broadway Rd #401
Contact: 602-830-3883
Hours: Monday-Friday, 8 AM–7 PM | Saturday-Sunday, 10 AM–4 PM
Attic Construction is a handy pick when your attic problem goes beyond just weak insulation. They handle insulation installation and removal, decontamination, rodent proofing, and air sealing under one roof.
I like that they can tackle the messy stuff before adding fresh insulation. That’s especially useful when old material has been contaminated or pests have turned the attic into their own little condo.
Their radiant barrier service is another plus for Phoenix homes battling serious summer heat.
Free attic inspections make it easier to see what actually needs fixing before work starts.
The main drawback is that their standard pricing isn’t readily available. You’ll need an inspection or quote before comparing costs with other local contractors.
Customer Reviews
We appreciate their dedication, workmanship, & professionalism
Our home is 87 years old. The attic was in need of a good clean out & new insulation. We felt we were in good hands with Liron, Jacob, Erin, Kyler, & the crew. Liron was able to have us scheduled within 48 hours of signing the contract & the installers were courteous & thorough. We appreciate their dedication, workmanship, & professionalism. Thank you, Attic Construction.

Extremely happy
The two Attic Construction technicians, Angel and Kyler, exceeded our expectations with having insulation blown in attic! They were professional, clean, laid plastic on garage floor, explained process, pics & gave us confidence the job would be done right. In Arizona, it’s necessary to insulate garage bc heat will destroy computer components in cars, batteries, even extra pool hoses (per pool guy) These home builders do bare minimum, sadly. Extremely happy we decided to have this project done with Attic Construction.

4. Phoenix Spray Foam Insulation
Address: 44 W Monroe St Apt 1905
Contact: 602-786-9221
Hours: Monday-Friday, 8 AM–6 PM
Phoenix Spray Foam Insulation is worth a look if your attic has awkward corners that seem designed to defeat ordinary insulation. They work with both open-cell and closed-cell spray foam for residential and commercial spaces.
I like that their service lineup extends beyond standard attics. They handle areas such as pole barns, crawl spaces, and other tricky spots where a tighter air seal can really matter.
Free estimates make it easier to see whether spray foam fits your project before spending a dime.
Their closed-cell option can be especially useful when you need strong thermal resistance in a limited space.
The main drawback is that their published services focus heavily on spray foam. If you want cellulose or blown-in fiberglass, you may need to call another contractor.
Customer Reviews
Their service exceeded my expectations
My home was built in the 70s, so it needed some attention. There were cracks and openings in the attic, and a friend recommended Phoenix Spray Foam Insulation. Their service exceeded my expectations. I highly recommend them for any spray foam insulation needs.

Highly recommend
I highly recommend this company. I needed a spray foam installation completed asap for a property that was going on the market. I called and they got right on the job! I will definitely be returning if I need service like these in the future.

5. Supreme Comfort
Address: 2900 E Adams St
Contact: (623) 400-6615
Hours: Monday–Saturday, 7 AM – 7 PM
Supreme Comfort makes sense if your attic and air conditioner seem determined to gang up on your power bill.
They handle attic insulation alongside heating and cooling work, which keeps the whole comfort problem under one roof.
I like that broader approach for Phoenix homes where insulation and HVAC performance often go hand in hand. It can save you from juggling separate contractors just to figure out why certain rooms never cool down.
They serve the Greater Phoenix area and offer estimates before work begins.
Customer feedback is generally positive, with attic insulation and duct-sealing work mentioned among their services.
The drawback is that you’ll need to ask for specifics before comparing them with insulation-focused contractors, as pricing and methods aren’t readily available for reference.
Customer Review
