I highly recommend EM Energy & Air!! We had them remove and replace our attic insulation, clean and sanitize our attic and install new insulation and a heat shield in our home. The crew was awesome. They laid down plastic for the pathway, and around the entire area where work was to be performed. It took about 5 hours and they were non-stop working to completion. We got a few quotes and were well worth our cost. Can’t say enough good things about the entire process, from initial meeting, quote to work completed!!

As a Professional Engineer and HVAC business owner, I can certainly recommend E&M. I pursued multiple bids and Eilon was by far the most knowledgeable, thorough and professional. His field team was courteous, worked neatly, and finished the project on time. We already notice that the HVAC system runs less and the house holds temperature better. Strong endorsement from me.

we are very pleased having hired EM Energy & Air trough Eilon to tackle our attic project. From scheduling an appointment to getting the job done all went smoothly and faster than we expected. After reaching out on Sunday our attic got renovated within 1 week time frame: removing the old insulation, clean up of the attic, installing a whole house fan, redoing the HVAC pipes and insulation. I am very pleased with work done and professionalism of the crew. They worked very clean and swiftly ( all work was done in 1 day).

I recently hired EM Air & Energy to clean up and re-insulate my attic and handle some heating work at my home. I’m thrilled with the results and highly satisfied with their service! Elion visited my home to assess the attic and heating setup. He was thorough, knowledgeable, and gave me valuable suggestions tailored to my needs. The contractors who came to do the actual work were efficient, hardworking, and professional throughout. The pricing was fair, and I truly feel I received excellent value for the cost. The entire process was seamless, and I’m happy to recommend EM Air & Energy to anyone looking for top-quality service.

I called up these folks initially to get an estimate to clean out my attic. They provided me the best bid I received in terms of details and price. After a candid conversation with Eilon, I decided to have EM energy and air also install new insulation and seal off my attic. The crew were very thorough in sealing off all the possible rodent entry points and did a great job with the cleaning. And the insulation came just in time for the heat wave. It made a 10 degree difference in the inside temperature of my home. Great experience, would highly recommend them.

Installing two heat pump with EM was a breeze; communication was very timely and the job was done well and as agreed. Quote process: They got me a fair quote same-day by just from sending them info over text (while other companies took weeks) and the price was fair. Change orders: I decided later I want two units, and again it was a smooth process. Also later there was an equipment change – and it made it convenient for me. Job Day: 4 guys arrived as agreed and get it done same day. I talked to most of them and all were polite, nice and upbeat. They let me inspect the work closely, made sure I am happy and give me tips on next steps. TLDR; Would hire them again and I am happy to recommend to my neighbors!

Types of Insulation We Can Install
The most common types of insulation we install include blown-in fiberglass and cellulose, fiberglass batts, and mineral wool. Each has different benefits and use-cases.
Blown-In Fiberglass and Cellulose Insulation in San Jose
Blown-in insulation is ideal for attics and wall cavities. It provides excellent coverage, and it’s highly effective at reducing energy loss. Blown-in fiberglass is made from at least 61% recycled glass, which makes it environmentally friendly, and more importantly, non-combustible. Blown-in cellulose, made from recycled paper products, is another eco-friendly option that is also resistant to pests and mold.
Fiberglass Batts Installation in San Jose
We install fiberglass batts for many customers in the San Jose area. These are pre-cut sections of fiberglass insulation that are perfect for insulating walls, floors, and ceilings. Fiberglass batts are durable and resistant to moisture, so they work well in areas prone to dampness. As with many modern insulation materials, the high recycled content in our fiberglass batts is non-combustible.
Mineral Wool insulation
Mineral wool provides thermal insulation, and as an added benefit, it reduces sound pollution in your home. It is denser than fiberglass, which allows it to block sound more effectively, making it ideal for reducing noise from external sources like traffic or noisy neighbors. Mineral wool is also highly fire-resistant.
Why You May Need to Replace Your Insulation in San Jose
Temperature control is an obvious reason, but there’s more to it than that. Many older homes, especially those with insulation installed decades ago, might be harboring dangerous materials like asbestos and formaldehyde. Replacing old insulation with our certified, toxin-free alternatives can keep your family safer.
Modern materials also improve your home’s acoustic insulation. With thicker, more efficient insulation, outside noises such as airplanes, trains, and the neighbor’s band next door become much less intrusive!
Fire safety also comes into play. Many older insulation materials do not meet today’s fire safety standards. Our insulation options, particularly fiberglass and mineral wool, are 100% non-combustible, reducing the risk of fire spreading through your home.
When we replace insulation, we can also address any potential issues with rodent infestations. Old insulation can be a haven for pests, particularly in attics and crawl spaces. By removing the old material, we can thoroughly inspect your home’s structure, identify rodent entry points, and seal them up.

Understanding Insulation Performance and Longevity
How Insulation Supports HVAC Efficiency
Most homeowners understand that insulation helps regulate indoor temperature, but they may not realize how directly it affects HVAC system performance. When insulation is worn out, missing, or poorly installed, the heating and cooling system has to work harder and longer to maintain a comfortable temperature. That often leads to higher utility bills and more frequent repairs. By upgrading insulation in the attic or crawlspace, especially when combined with new ductwork, many homeowners notice better temperature balance, fewer hot or cold spots, and reduced strain on their furnace or air conditioner.
What to Know About R-Value
R-value is a number that indicates how well an insulation material resists heat flow. Higher R-values provide better thermal performance, but it is not always about picking the highest number. Attics in San Jose typically benefit from insulation rated between R-38 and R-60, depending on roof slope, attic depth, and local energy standards. Blown-in materials like fiberglass and cellulose often provide high R-values per inch, while batts are easier to fit between joists. We take the time to explain your options and help you understand what makes the most sense based on your home’s layout and your goals for comfort and efficiency.
Can You Add New Insulation Over the Old?
Sometimes. If the existing insulation is clean, dry, and free of pests, it may be possible to layer new insulation on top to increase coverage. But if the material is sagging, moldy, or contaminated with rodent waste, removal is the safer and more effective choice. During our inspection, we evaluate the condition of your insulation and attic airflow before making a recommendation. If removal is needed, we disinfect the area and take steps to block off common rodent entry points before installing the new insulation.
How Long Does Insulation Last?
Insulation is not a one-time investment that lasts forever. Even high-quality fiberglass can settle or lose performance after 20 to 30 years. Cellulose tends to need attention sooner, especially in areas with moisture exposure or rodent activity. If your home is older and has not had an attic or crawlspace inspection in years, it may be time for an upgrade. Replacing degraded insulation improves energy efficiency, indoor comfort, and even soundproofing throughout the home.
FAQs Regarding Insulation Installation in San Jose
What types of insulation do you install?
We install blown-in fiberglass, blown-in cellulose, fiberglass batts, and mineral wool. Each material is chosen based on your attic depth, wall cavities, and energy efficiency goals. All of our products are sourced from trusted U.S. manufacturers.
How do I know if my insulation needs to be replaced?
Signs include uneven temperatures between rooms, higher utility bills, drafts, or visible damage such as moisture stains, mold, or rodent debris. If your insulation is more than 20 years old, a free inspection can reveal whether it is still performing effectively.
Can you add insulation over existing material?
In many cases, yes. If the current insulation is dry, clean, and free of pests, we can layer new material on top to increase coverage and improve performance. If the insulation is damaged or contaminated, removal and replacement is a better option.
What is the recommended R-value for attic insulation in the Bay Area?
Most homes benefit from an R-value between R-38 and R-60 in the attic. The exact recommendation depends on the roof slope, attic depth, and whether your HVAC system runs through that space. We will explain your options during the inspection.
How does insulation affect my HVAC system?
Proper insulation keeps conditioned air inside and reduces the workload on your heating and cooling system. This lowers energy use, helps maintain even indoor temperatures, and can extend the lifespan of your furnace or air conditioner.
Do you remove old or contaminated insulation?
Yes. We safely remove damaged or pest-infested insulation, disinfect the area, and seal rodent entry points before installing new material. This process improves indoor air quality and prevents future infestations.
Can upgrading insulation help with noise reduction?
Yes. Dense materials like mineral wool provide excellent sound absorption. Upgrading insulation in walls or between floors can reduce outside noise and create a quieter home environment.
How long does insulation installation take?
Most attic insulation projects take a single day. Larger homes or jobs involving old insulation removal may require up to three days. We will give you a clear schedule before starting work.
