Attic Insulation Company in Palo Alto: Blown-In, Batt & More
Attic Insulation Estimates on the Spot: Best Local Warranty
The attic is usually the first place to lose energy in a home. Old or insufficient insulation can allow heat to escape in the winter and accumulate in the summer, and this leaves the rest of the house struggling to maintain a steady temperature. The temperature swings dramatically in Palo Alto between cool nights and sunny days; a poorly insulated attic can drive up energy bills and put unnecessary strain on your HVAC system.
At EM Energy & Air, we help homeowners in Palo Alto upgrade their attic insulation with modern and high-performing materials. Our team completes most projects in a single day and provides free inspections with detailed estimates during the same visit. We install fiberglass, cellulose, mineral wool, and other attic-appropriate materials based on your home’s layout, needs, and energy goals. If your attic has never been upgraded or was last insulated decades ago, now is the right time to make a change.
Improve Your Attic, Improve Your Quality of Life

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!

How Do You Choose the Right Insulation Type? (Call Us)
Blown-In Fiberglass and Cellulose
For open attic floors, we often use blown-in fiberglass or cellulose. These materials are efficient, affordable, and easy to install across irregular spaces. Cellulose has the added benefit of being made from recycled content.
Fiberglass Batts and Mineral Wool
Batts are a good option for attics with open cavities or where extra soundproofing is desired. Mineral wool offers a higher fire resistance rating, which makes it a smart choice in certain homes.
How Bad Insulation Affects Your HVAC System
Energy Bills Rise Without Clear Explanation
When insulation breaks down, your heating and cooling system has to work harder to keep your home at the temperature you set. That often leads to energy spikes and shorter equipment lifespans.
Hot or Cold Air Escapes Into the Attic
If your ducts run through the attic, poor insulation allows treated air to change temperature before it reaches your rooms. Sealing and insulating this space keeps more of that air usable.
What Damages Attic Insulation Over Time
Age, Pests, and Construction Work
Time alone causes insulation to settle and lose its effectiveness. Rodents often tear it apart for nesting. Construction or roof repairs can leave behind gaps or missing sections that reduce the overall thermal barrier.
Moisture and Poor Ventilation
Even small roof leaks or humid air can affect attic insulation. Damp insulation loses R-value and can lead to mold problems. In these cases, we remove and replace it as part of a full upgrade.
What the Installation Process Looks Like
Safe Removal, Air Sealing, and Full Coverage
We start by removing any old or damaged insulation. Then we seal common air leak points, like gaps around wiring, pipes, and attic hatches. From there, we install new insulation to the correct depth based on Palo Alto’s energy standards.
Our team works cleanly and efficiently. Most projects are done in a single day.
Add-Ons That Improve Attic Performance
Radiant Barriers and Ventilation Upgrades
Radiant barriers help reflect heat before it enters the attic, which is especially helpful during Palo Alto’s warmer months. If your attic lacks ventilation, we may recommend ridge vents or attic fans to move air more effectively.
Duct Sealing and HVAC Support
We also offer duct sealing as part of our attic services. If your HVAC system runs through the attic, sealed ducts paired with new insulation can reduce energy waste and help maintain even temperatures.

How Attic Insulation Affects Heating and Cooling
Many homeowners in Cupertino notice that their upstairs rooms are hard to keep comfortable. That often has more to do with insulation than the HVAC system itself. A poorly insulated attic allows heat to pass freely between your home and the roof cavity. In summer, that creates hot spots upstairs. In winter, it forces your furnace to run longer to compensate for heat loss.
Improving attic insulation can ease the burden on your heating and cooling systems, extending their life span and reducing energy use. It can also solve uneven temperature problems, especially in older homes with ductwork running through the attic.
Other Forces That Damage Insulation Over Time
Rodents and pests often find their way into the attic and make nests in old insulation. This contamination is not only unsanitary but can also damage the insulation’s structure and effectiveness. Roof leaks are another common culprit, allowing moisture to seep in and cause mold or mildew growth.
Even without visible damage, insulation naturally settles over time. After 20 to 30 years, it may lose up to half of its original effectiveness. In homes that have undergone remodeling or roof work, it’s also common to find sections of attic insulation removed and never replaced.
Our Installation Process from Start to Finish
We begin by removing any insulation that is damaged, compacted, or contaminated. From there, we inspect for air leaks and seal areas where heat may be escaping. This might include sealing around plumbing penetrations, light fixtures, or vents. Once the attic is properly sealed, we install the new insulation to the recommended depth for energy savings and comfort.
We treat every attic insulation project as an opportunity to make the home more comfortable and energy efficient. If ventilation or ductwork adjustments are needed, we address those at the same time to keep everything working together.
Add-Ons That Help Your Insulation Perform Better
In some homes, insulation alone may not solve the full problem. That’s why we often recommend pairing attic insulation with upgrades like radiant barriers or attic fans. A radiant barrier reflects heat away from the attic in summer, helping the insulation work more efficiently. Attic fans promote air movement and keep the space from overheating.
If ductwork runs through the attic, we may also recommend duct sealing or insulation to reduce air loss. These improvements work together to reduce your utility bills and keep your home more stable year-round.
