We had Royal Aire install central heating and air conditioning in our home. Russ and his team were professional, efficient, and personal. They were patient with us when we asked questions, and were quick to address any concerns we had. The system they installed works like a champ, and we really couldn’t be happier with the whole experience. We accessed Royal Aire through Costco’s program, and would do it again the same way.

Richard did a great job of assessing the problem with our ventilation system and recommending immediate action. He requested other staff to come to my house immediately to repair the exhaust system. He also signed me up immediately for the Royal Gold Plan and immediately provided me with my first maintenance service. He did a great job and I would like to request him to return in the future for the next service.

Diaz Insulation was great to work with and reasonably priced. I had the crew come out and remove the old insulation I had in my attic, which has a very small crawlspace. Then, I had the crew come back a couple weeks later and blow in new insulation. They answered all questions I had, the crew was professional and cleaned up after the work was complete, and the job itself was done very well. Thank you for a job well done!

I highly recommend Diaz Insulation. A professional team from the first call to project completion. Prompt, professional, easy to work with, and friendly. It was a pleasure to work with this team. Roy Diaz came out within a couple of days of a call to ask for a bid from them. He was very professional, offered options to box in my whole house fan, recommended and explained different R-values for my home and garage, and I most appreciated his recommendation to upgrade any electrical that I may need in the future before they blow in the insulation. Once I gave them the call that I was ready for them, they were out the next day, and their installation team was prompt, professional, and courteous.

Diaz Insulation cleaned my crawlspace and removed all the insulation. Rodents compromised the insulation for years. I tried doing this job myself and it was too difficult. They did a thorough job and I'm very happy with the outcome. Great Job!

Frequently Asked Questions — Spray Foam Insulation in Chico

Does spray foam insulation work well in hot dry climates like Chico?▼
Yes — spray foam is highly effective in hot dry climates like Chico, CA. While moisture control is less of a concern than in humid climates, the air sealing properties are critical for keeping hot desert air out and cooled air in. In extreme heat climates, an unsealed attic can reach 150°F+, dramatically increasing AC load. Spray foam in the attic can reduce attic temperatures by 30–40°F.
What is the best area of my home to insulate in Chico?▼
In hot dry climates like Chico, CA, the attic is typically the highest-impact area to spray foam insulate. Desert sun heats roofs to extreme temperatures, and an uninsulated attic transfers that heat directly into your living space. After the attic, crawl spaces and rim joists are the next highest-impact areas. A local contractor can perform an energy audit to identify where your home loses the most conditioned air.
Is spray foam insulation worth the cost?▼
For most homeowners, yes. Spray foam creates an air-tight seal that traditional insulation cannot match, reducing energy bills by 15–35% annually. It also adds structural rigidity, acts as a moisture and vapor barrier, reduces outside noise, and can increase home resale value. The higher upfront cost compared to fiberglass is typically recovered within 3–7 years. One important note: because spray foam creates a very tight building envelope, proper mechanical ventilation is important to maintain healthy indoor air quality and prevent interior moisture buildup. This is typically handled by an Energy Recovery Ventilator (ERV) — a system that brings fresh outside air in while pushing stale air out, recovering the energy from the outgoing air so you don't waste what you paid to heat or cool — or a Heat Recovery Ventilator (HRV), which works similarly but is optimized for cold climates. A qualified contractor will assess whether your home needs ventilation upgrades as part of the installation.
How much does spray foam insulation cost?▼
Spray foam insulation typically costs $1.00–$3.00 per square foot installed, depending on the type and your location. Open-cell foam runs $0.44–$0.65 per board foot, while closed-cell foam costs $1.00–$2.00 per board foot. A typical 2,000 sq ft home attic costs $2,000–$6,000. Most homeowners recoup this investment within 3–7 years through energy savings of 15–35% annually.
What is the difference between open-cell and closed-cell spray foam?▼
Open-cell spray foam is softer, less dense, and less expensive. It expands significantly and is ideal for interior walls, attics, and soundproofing. Closed-cell spray foam is denser, stronger, and provides a moisture barrier — making it better for exterior applications, crawl spaces, and areas prone to flooding or humidity. Closed-cell also has a higher R-value per inch (R-6 to R-7 vs R-3.5 to R-4 for open-cell). One key difference: open-cell foam allows some vapor movement, while closed-cell acts as a vapor barrier — an important consideration for your home's ventilation needs.
How long does spray foam insulation last?▼
Spray foam insulation is one of the most durable insulation options available, with a lifespan of 80+ years when properly installed. Unlike fiberglass batting which can sag and settle over time, spray foam maintains its shape and insulating properties indefinitely. It will typically outlast the building it is installed in.
How do I find a qualified spray foam insulation contractor?▼
Look for contractors who are licensed, insured, and have verifiable reviews. Spray foam requires specialized equipment and training — improper installation can cause off-gassing, adhesion failure, or fire hazards. Ask for references, verify their insurance, and get at least 2–3 quotes. A qualified contractor will also assess your home's ventilation needs — a tightly sealed spray foam installation requires adequate mechanical ventilation to prevent moisture and indoor air quality issues. FoamMatch pre-screens all listed contractors for licensing and insurance so you can compare verified professionals in your area.
How long does spray foam installation take?▼
Most residential spray foam jobs take 1–2 days depending on the size of the area. A standard attic takes 4–8 hours. After spraying, the foam cures within 24 hours, though most contractors recommend waiting 24–72 hours before occupying the space due to off-gassing during the curing process.
Does spray foam insulation need to be replaced?▼
No — spray foam insulation does not need to be replaced under normal circumstances. Unlike fiberglass insulation which degrades over time, spray foam maintains its R-value and air sealing properties for the life of the building. The only reasons to remove or replace spray foam are water damage, renovation work, or improper original installation.
