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 a Whole House Fan Cools a Home
Whole house fans work by pulling fresh outdoor air inside while pushing warm indoor air out through attic vents. Instead of recirculating the same conditioned air, the system flushes out heat and replaces it with cooler air from outside. During the evening or early morning, when outdoor temperatures drop, the fan cools the home quickly without relying on air conditioning.
The fan is mounted in the attic and connected to ceiling vents, allowing hot air to escape. When windows are slightly open, cool air moves in as the fan removes trapped heat. This natural cooling method reduces indoor temperatures in minutes and keeps air feeling fresh.
The Benefits of Installing a Whole House Fan
Lower cooling costs make a big difference over time. Running a whole house fan uses far less energy than air conditioning. Many homeowners see a drop in their electricity bills after installing one.
Better indoor air quality makes the home feel fresher. The fan constantly moves air through the house, reducing humidity, odors, and allergens. Stale air gets replaced with fresh outdoor air, which makes a noticeable difference in comfort.
Cooling happens much faster than with air conditioning. Instead of waiting for the HVAC system to lower temperatures, a whole house fan moves large volumes of air in minutes.
An HVAC system lasts longer when it doesn’t run as often. Less strain on the air conditioning unit reduces wear and tear, helping it last for years without frequent repairs.
How to Tell if a Whole House Fan is a Good Fit For You
Whole house fans work best when outdoor temperatures drop at night or in the early morning. Homes in Palo Alto with high attic temperatures or poor ventilation benefit the most. If air conditioning runs constantly but the house still feels stuffy or warm, a whole house fan may be the solution.
Before installing a fan, our team inspects the attic to check for proper airflow. If ventilation is insufficient, we may recommend attic vent upgrades or additional fans to optimize performance.
The Whole House Fan Installation Process
Installing a whole house fan requires careful planning to achieve the best cooling effect without creating air pressure imbalances.
The process begins with a home evaluation to determine the right fan size and venting requirements. The attic, air circulation patterns, and square footage all factor into the decision.
The fan unit is installed in the attic, typically between ceiling joists. It connects to vents that allow warm air to escape, which prevents heat from building up inside.
Attic ventilation must be adequate for the system to work properly. If necessary, we install ridge vents, soffit vents, or attic fans to improve airflow.
Once the system is in place, our team runs performance tests and adjusts airflow pathways to achieve maximum cooling efficiency.
Why Attic Ventilation Matters
Attic ventilation helps regulate temperature, prevent moisture buildup, and improve overall air circulation. Without proper airflow, heat gets trapped inside, making it harder to cool the home. Poor ventilation also leads to high humidity, which can cause mold growth, wood rot, and insulation damage.
We install attic ventilation solutions that work alongside whole house fans to improve efficiency. Attic fans actively push out hot air, while ridge and soffit vents allow passive airflow. Radiant barriers also help reflect heat, reducing attic temperatures before the fan even starts running.
Whole House Ventilation and Air Quality Upgrades
Good ventilation does more than cool the home. It improves air quality by reducing pollutants, allergens, and humidity levels. A well-ventilated home feels fresher and reduces the risk of mold and stale air buildup.
Our team offers custom ventilation upgrades for better indoor air quality. Exhaust fan installation reduces humidity in kitchens and bathrooms. Heat recovery ventilators (HRVs) bring in fresh air while maintaining temperature balance. Duct cleaning and sealing improve airflow efficiency by eliminating leaks and dust buildup.
