When both of our AC units unexpectedly stopped blowing cold air Top Energy Solutions was able to get a tech out quickly to diagnose the problem. It was discovered our system had a leak in the lines running under a patio. Leor came up with a solution for us and the next day removed the old systems and installed 2 new systems. The crew was efficient, professional, and did quality work. Because of that we had Leor and his crew come back the next day and insulate the attic and install an attic fan. I couldn't be happier with the communication, efficiency, and professionalism of Leor and his crews!

Top Energy Solutions is the best contractor I have hired. Leor is responsive and professional. I acquired three quotes to have my HVAC system replaced. I accepted Leor’s quote, and the installation started, and was finished by the end of the next day - amazing. A crane was required to remove and replace the AC unit on a three story house. His installation crew was very friendly and very good natured. He beat the other quotes by more than two thousand dollars for the same equipment. Leor is a general contractor and has crews for most home repairs. I will be hiring Top Energy Solution again soon.

Outstanding service from a company that truly brightened our home's efficiency. We had an older attic with very little insulation, and the Bright Sky team transformed it. Their quote was clear and competitive, and the installation crew worked efficiently with great attention to detail. They ensured the insulation was evenly distributed and that all vents were clear for proper airflow. The improvement in comfort is immediate—no more drafts and our HVAC system runs much less frequently. Highly recommended.

As a new homeowner, I was overwhelmed by the process of reinsulating. The team at Norwalk Insulation Pros made it simple.

Nina Lillian★★★★★3 weeks ago

Our experience with Norwalk Insulation Pros was exceptional from start to finish. We were impressed by their thoroughness during the estimate—they didn't just glance at the attic but did a full walk-around to identify potential problem areas. The installation crew was fantastic; they worked hard, answered all our questions, and even pointed out a small vent issue we were unaware of. The finished work is neat, even, and exceeds building codes. Our house is noticeably quieter and holds temperature perfectly. It’s clear they take pride in their craft and customer satisfaction.

Choosing Paramount Attic Insulations was an easy decision based on their reviews, and they exceeded every expectation. The entire process was smooth: easy scheduling, a prompt and competitive quote, and a flawless installation day. The crew was friendly, answered all our questions, and worked with impressive speed and skill. The difference in our home is profound—it's cozier in winter and cooler in summer. We've already seen a drop in our gas and electric usage. A first-class operation from start to finish.

Santos Chaya★★★★★a month ago

We had a fantastic experience with Paramount Attic Insulations. From the initial estimate, which was detailed and honest, to the final clean-up, everything was professional. The crew arrived on time, worked efficiently in the brutal attic heat, and were incredibly respectful of our home. They installed a deep, even layer of fresh insulation and pointed out several areas where they did extra air sealing. The difference in our home's comfort was immediate, and our next energy bill was significantly lower. Highly recommend this local, reliable company.

Ariel Davon★★★★★3 weeks ago

The company really cares that their employees do an all around excellent job. I previously used Service All-Stars to replace my heater. Now they have installed my A/C unit. They do excellent work.The techs were friendly and informative about the details of the work they were doing. I appreciate the fact the workers worked quietly and efficiently. The owner is receptive to constructive criticism which is a big plus in my book. I will continue to call upon Service All-Stars for my HVAC needs.

The team that Sal sent (Brandon and Evan) did a fantastic job on repiping my 60 year old house here in Long Beach. I found a leak in my tankless water heater closet and called them out to take a look. My house has a slab foundation and turns the leak was coming in from the main-line under the soil and then through the concrete to the water heater closet in the middle of the house. They dug down through the concrete and rather than just asking the guys to patch the galvanized pipes, I figured it best to do a full house re-pipe through my tight attic since the plumbing is 60 years old. Good thing because in the process, another leak was detected in the wall between my bathroom vanities. The guys were friendly and hard-working, the process took 4-5 days and I was informed of where they would have to cut through the walls to connect all the pipes. They definitley routed the pipes in the least invasive way. They also tuned up my HVAC system and tankless water heater while they were here. I would highly recommend Service All-Stars for your plumbing and HVAC needs. -DC

Frequently Asked Questions — Spray Foam Insulation in Bellflower

These are the questions Bellflower homeowners ask most about spray foam cost, R-value, and open- vs. closed-cell foam — with context for local pricing and roughly 27% typical energy savings. Compare the 6 verified Bellflower contractors above for exact quotes.

Does spray foam insulation work well in hot dry climates like Bellflower?▼
Yes — spray foam is highly effective in hot dry climates like Bellflower, 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 Bellflower?▼
In hot dry climates like Bellflower, 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 in Bellflower, CA?▼
In Bellflower, CA and the surrounding area, spray foam insulation typically costs $1.00–$3.00 per square foot installed, depending on the type and your home's specifics. 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 in Bellflower costs $2,000–$6,000. Most Bellflower 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 in Bellflower, CA?▼
When searching for a spray foam contractor in Bellflower, CA, look for ones 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 Bellflower 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 in Bellflower 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.
