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 Mini Splits Deliver Heating and Cooling Without Ductwork
Mini splits work by moving heat rather than generating it. They use a refrigeration cycle to extract heat from one area and transfer it to another. In summer, heat is pulled out of your indoor space and released outside. In winter, that process reverses, and the system extracts heat from outdoor air and brings it inside, even on cold days.
Each indoor unit connects to a small outdoor condenser through a thin set of lines. These lines carry refrigerant, power, and drainage. Indoor units are typically wall-mounted and operate independently, allowing you to control the temperature in each room.
Because they don’t rely on ductwork, these systems avoid common efficiency losses. Traditional forced-air systems lose a significant amount of energy through ducts, especially when those ducts are poorly sealed or routed through uninsulated attics. A ductless setup delivers air right where it’s needed.
Where Ductless Systems Make the Most Sense
Ductless systems work well in a wide range of situations. Some homeowners in Sunnyvale use them to supplement rooms that are always too hot or too cold, especially upstairs bedrooms or sunrooms. Others use them in converted garages, home offices, or backyard cottages.
If you’ve recently added an accessory dwelling unit or finished a basement, a mini split is one of the most cost-effective ways to heat and cool that space. These systems are ideal when extending existing ductwork would be expensive or logistically difficult.
They’re also perfect for homes without central air. Many of the houses built in Sunnyvale in the 1950s and 60s were designed before modern HVAC systems became standard. A ductless system avoids the need to cut into ceilings or walls, making it easier to upgrade your comfort without a full renovation.
A Few of Our Projects
Energy Efficiency That Keeps Operating Costs Low
Mini split systems are known for their high efficiency ratings. Many units carry a SEER (Seasonal Energy Efficiency Ratio) rating well above 20, which far exceeds the minimum standards required for California. Variable speed compressors adjust their output to meet the room’s demand, which means they avoid wasting energy on short, inefficient bursts of heating or cooling.
Zoned control is another major benefit. You can adjust each indoor unit separately, so you don’t waste money conditioning rooms you’re not using. This gives you precise control over your environment and allows for energy savings throughout the year.
Homeowners often pair mini split systems with solar power to maximize long-term cost savings. If you’re considering upgrades that include both heating and cooling improvements, we’re happy to help you think through the big picture.
What to Expect From the Installation Process
Once we’ve walked through your home and identified where the indoor and outdoor units should go, we’ll provide a detailed estimate. We include everything: equipment, materials, labor, taxes, and any minor repairs that may be required afterward. There are no hidden charges or vague disclaimers.
On installation day, our team arrives ready to work. We mount the indoor units, drill the necessary access points, route the line sets with care, and place the outdoor condenser where it can operate quietly and efficiently. We also vacuum the refrigerant lines before charging the system. This step is sometimes skipped by low-cost contractors, but we consider it non-negotiable. It protects the long-term function of your system.
After the system is up and running, we double check airflow, calibrate controls, and make sure you understand how to operate everything with ease. You can also reach us afterward with any questions. We are a small, locally run business, and we keep close contact with all of our clients.
