Cupertino Whole House Fan + Ventilation Services
Excellent Pricing, Free Estimates, Unbeatable Warranties, and Rapid Turnaround Time
The Smart Way to Cool Your Home
Air conditioning can only do so much, especially when you’re trying to keep energy bills in check. Running the AC all day might help a little, but it won’t always keep the air feeling fresh. A whole house fan is a more natural, affordable way to bring cooler air into the home, and it can make a noticeable difference in comfort.
At EM Energy & Air, we install fans and ventilation systems that improve airflow, reduce indoor heat, and support a healthier living environment. We keep the process simple with upfront pricing, quick installations, and American-made equipment that’s built to last. Most jobs wrap up in just one day.

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!

What Whole House Fans Actually Do
Replace Trapped Heat with Cooler Air
Instead of relying on your HVAC to recirculate the same air, a whole house fan pulls in outdoor air through your windows while pushing warm air into the attic and out through the vents. It works best in the early morning or evening when temperatures drop outside.
The fan is installed in the attic and connects to ceiling vents inside. Once it’s on, stale air moves upward and exits while fresh air enters through the windows. This can cool the entire home in a matter of minutes.
Benefits of Whole House Fan Systems
Energy Savings Without the Wait
These fans cost far less to run than central AC systems. They begin cooling quickly, and many homeowners notice a drop in their electric bill during the warmer months.
More Than Just Comfort
The steady airflow helps reduce humidity, odors, and allergens. When you can bring in clean outdoor air regularly, the entire home feels fresher. The fan also eases the burden on your HVAC, which helps extend its service life and may reduce repair needs.
Is a Whole House Fan Right for You?
What We Look For During a Site Visit
Homes that heat up during the day but have cooler nights are a great match. If your attic holds onto heat or your living spaces stay stuffy even with the AC running, this kind of system might be the right choice. We’ll take a look at your attic and ventilation setup to make sure everything works together properly.
If more airflow is needed, we can upgrade attic vents or add fans to help the system perform better. We’ll walk you through your options during the visit.

What to Expect During Installation
One-Day Installation with Long-Term Results
It starts with a free inspection and sizing recommendation. We’ll consider square footage, ceiling layout, and air movement patterns before suggesting a specific fan.
Installation usually takes just a few hours. We mount the unit in the attic and connect it to interior ceiling vents. If the attic doesn’t have enough ventilation, we’ll install ridge or soffit vents so that air can escape properly.
We also test the system after installation to check airflow and cooling time. We leave your space clean and ready to use with no hassle and no mess.
Attic Ventilation Helps Everything Work Better
Why It Matters
Attics that trap heat affect the rest of the house. Without proper airflow, temperatures climb and moisture builds up. That can damage insulation, encourage mold, and push your cooling system to work harder than it should.
We offer passive and powered attic vents, as well as radiant barriers that reflect heat before it settles in. Each solution is designed to work with the whole house fan and keep things running smoothly.
Full-Home Ventilation Support
Fresh Air Throughout the House
We also install ventilation systems for bathrooms, kitchens, and laundry rooms. These setups reduce humidity and help remove air that feels stale. Our team can add duct sealing, vent repair, or heat recovery ventilators that bring in fresh air without wasting energy.
Each upgrade is tailored to your home’s layout, and we focus on improvements that make everyday living more comfortable and healthy.
