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!

Insulation Services That Make a Big Difference
Many homes in the Bay Area have insufficient or deteriorated insulation, especially if they were built before modern building codes raised the standard. Our team installs high-quality insulation in attics, walls, ceilings, and crawlspaces to help regulate temperature, reduce outside noise, and lower monthly energy bills.
We use safe, American-made materials like fiberglass batts, blown-in cellulose, and mineral wool. These materials improve energy performance and protect against fire, pests, and moisture buildup. Our insulation work is backed by an unlimited warranty on labor, and we include attic sanitation and rodent-proofing when needed. If you’re unsure of your home’s current insulation quality, we’ll inspect the property and provide an estimate you can trust.
Air Duct Installation, Cleaning, and Repairs
If your new home has musty smells, uneven airflow, or older ductwork, it’s worth checking for hidden issues. Leaky ducts can allow dust, mold, and outdoor allergens to circulate inside, while poorly insulated or damaged ducts make your HVAC system work harder than it should.
EM Energy & Air offers professional duct cleaning, repairs, and full ductwork replacement when necessary. Our modern duct systems are energy-efficient and built to last, using well-insulated materials that meet today’s airflow standards. We also take extra care during cleaning, using high-powered vacuums and professional-grade tools to remove buildup safely and thoroughly.
HVAC Upgrades and Installation for New Owners
One of the most common projects for new homeowners is replacing or upgrading the heating and cooling system. Older homes might have no central air at all, or they may rely on aging furnaces and outdated window units. We install high-efficiency heat pumps, central air systems, and ductless mini splits, helping homeowners pick the right option based on the structure, layout, and size of their home.
Heat pumps are a great option for Bay Area homes because they provide both heating and cooling with very little electricity use. Central air is another popular choice, especially when installing or upgrading ductwork. And for homes without ducts or those looking for room-by-room comfort, ductless mini splits provide clean, quiet, and energy-efficient performance.
All of our HVAC installations include high-quality, American-branded systems from manufacturers like Carrier, Trane, and Lennox. We offer accessible financing, and most installations are finished in just one to three days.
Attic Renovations and Rodent Control
Buying a home means inheriting whatever was left behind in the attic. That sometimes includes rodents, droppings, chewed wires, and shredded insulation. Our team performs full attic renovations, including removal of contaminated insulation, sanitation, and repairs. If rodents are present, we seal every entry point and provide a long-term exclusion solution so they don’t return.
We also install attic fans and whole house fans to improve airflow and reduce heat buildup in the summer. Attic heat can cause your HVAC system to run longer and harder, and many older homes lack the ventilation to prevent this issue. Radiant barriers and new insulation materials can work together to keep the entire structure cooler and more efficient.

Crawlspace Moisture Mitigation
If your new home has a crawlspace, that’s another area worth inspecting. Moisture buildup can lead to mold, structural damage, and pest activity. We install vapor barriers and perform crawlspace encapsulation to block moisture and keep your home’s foundation in good condition. For homes with standing water or poor drainage, we can also install sump pumps or recommend improvements to your drainage system.
