Several years ago, we had our first HERS test performed by Elem3nts - and no surprise, our 40 year old ducts were leaking badly. Fast forward to the present, the HVAC company we selected for a new heat pump and ducts uses Elem3nts to do the required HERS testing AND handle applying for the homeowner's rebates from Silicon Valley Clean Energy and TECH Clean (very convenient). The entire process was smooth - quick and painless. The Elem3nts team was on time, professional, and left the house just as it was after they were finished. They're very experienced and knowledgeable about HERS testing. Communication around scheduling was excellent, and one rebate has already been received and the other is on its way. Elem3nts has been great! read more

This was such a positive investment and experience. Professionalism from the start of the process through finish. Alfredo and his assistant came to my home in Willow Glen and performed a full evaluation of where the energy loss was coming from and what options I had to mitigate it. His report was thorough and I liked that he prioritized what I need to do right away and what can wait. Alfredo had a call with me to go over the results of the various tests that were run and made sure I understood every detail. Very happy I engaged them and I am looking forward to having warmer winters and lower energy bills read more

The tester came in time and wear the shoes covering when prepared for the test. He told us about the whole process and checked each vent after "sealing". Very quick and efficient HERs test, responsible to any questions we had. read more

We had suspected our home had fairly abysmal efficiency, especially for heating and cooling, ever since we'd moved in a couple of years ago, and my husband discovered E3 Elements online and scheduled for them to come out and do the whole house energy audit. I honestly hadn't been aware that this type of service existed (we're first time home owners), but we're so glad it does and that we hired E3 Elements! Having an auditor for whom you are their only customer/client (ie. not attached to another company, such as HVAC or General Contractors) was important to us from the start, and with E3 Elements, that's what you'll get. Not only was Alfredo very candid and comprehensive with his recommendations, he really took the time to explain everything on his report to us, which is really helping us now in negotiating with other companies for the possible upgrades we are looking into. I also appreciate the practical and low-cost DIY fixes that Alfredo suggested we could do on our own, which we're also looking into now, and the information on available rebates that will hopefully help us save a bit on these projects. We had a follow-up call with Alfredo to discuss the final report as well, which allowed us some time for things to settle into our brains so we could formulate our next questions, and if we have more later, Alfredo has been very responsive and I believe he would probably answer any stray questions we come up with in the coming weeks. When Alfredo and his assistant Harold arrived at our house, they were extremely respectful of our space and tidy (which honestly is more than I can say for my house--I'm a messy person). They wore shoe covers when indoors and cleaned up after themselves such that you wouldn't have known they'd been in there, and were both polite and pleasant to work with while they were in our home. I cannot recommend E3 Elements and the energy audit work they do enough to other home owners! Alfredo will take good care of you! read more

We had Elements perform an energy audit of our home, and it was done very thoroughly and profesionally, they collected a lot more information about the entire house than I expected. The report was detailed and useful, and the follow-up call we had was very helpful in understanding how to prioritize the improvements, and they even provide a list of contractors with the different specialties. I highly recomend Alfredo and Elements. read more

Ive worked with many title 24 companys (hers raters and by far elem3nts are the best by far. Im a hvac contractor and they will show up on time and do great work. They are fast and efficient and rates are reasonable If you are looking fora title 24 company look no further. Btw alfredo the owner is super nice read more

Alfredo is very knowledgeable and gave me all the data I needed to make informed decisions to improve the efficiency of our home

I was looking for some answers about why my energy usage was so high during certain periods. The Elements assessment helped me identify the key drivers of my usage and where I might be able to make some improvements. Now it's on me to take next steps, but it feels good to be empowered with the facts! read more

We wanted to replace our gas furnace with a heat pump (for space heating and cooling) - and we were getting conflicting recommendations on how to proceed from various contractors. Luckily, we hired Elements for a home energy audit. Alfredo and team did a great job with the various tests, and explaining the results to us. In particular, we learned that our ducts and the return were not in good shape. Many contractors didn't even look at these when they gave us quotes. So we would have had a nasty surprise later after the new heat pumps were installed - when we would have learned that we needed to replace our ducts and fix the return. With the report Alfredo gave us, we were able to get on the same page with contractors and we love our new heat pump system. We also have addressed other energy saving projects that Alfredo suggested. Thank you Alfredo and team! read more

Alfedro did an amazing job in identifying areas of improvement, ranking them by largest impact for lowest cost. He educated me on various things and provided an impartial and honest opinion. read more

I was recommended by cost less heating and cooling in willow glen Alfredo were polite and respectful They did a great Job doing the title 24 test and everything went smooth. They cleaned up after they were done and there rates were very affordable title 24 passed in a heart beat Thank you Alfredo and your team read more

Completing a major renovation and unbeknownst to me, needed a HERS report. I had no idea what this was or how to find someone to do this. I typed in "HERS report" into Yelp, requested estimates and after several replies from different HVAC vendors stating they don't perform this testing, I received a friendly message from Elem3nts. Subsequently got on a call with Alfredo who very patiently walked me through what the testing entailed, how to find my title 24 requirements and off we went! Specifically wanted to review that Alfredo truly went above and beyond - noticing that my initial title 24 application was filed through a now defunct organization, he pointed this out and offered very helpful solutions. Having been involved with many subcontractors during the renovation, I've unfortunately had my fair share of unsavory interactions, so was so so grateful to have Alfredo and his very kind team helping me finally finish this renovation! Absolutely recommend Elem3nts if you're in need of HERS testing. read more

Alfredo was pleasant and easy to work with and very knowledgeable. He and his team did an energy assessment of our home using a process that was clearly explained and executed. Alfredo answered all questions and provided us with a detailed report, arming us with the information we needed to decide with confidence what needed to be done to make our home more comfortable and energy efficient. We have in fact followed through on recommended changes and are feeling good about the experience, particularly since our home is more comfortable today. read more

Since we had a new HVAC system installed and needed to get HERS testing done to receive PCE and BAYREN rebates, the HVAC company, DG Heating and Air Conditioning, had ELEM3NTS come out and and do the test. Ali was the technician who handled this for us and he was a pleasure to have in our home. He arrived on time, explained what he was doing, answered all our questions and let us know the results. The appointment was easy to make and the follow through with all the paperwork for getting the rebates has been great so far. This company has been a pleasure to work with especially Veronica in the office. read more

Alfredo and team at Elem3nts performed an energy efficiency assessment for our home. We're about to get a new HVAC system and have been bit overwhelmed by the choices. As part of the energy audit Alfredo provided the practical guidance we needed to get us ready to get bids from HVAC contractors. He helped us understand where our current system is OK, where it needs changes, and what solutions may be best to address the large upstairs / downstairs temperature differential in our house. Besides this, he provided a full energy audit, also recommending certain home sealing procedures we should do as part of the new system. Alfredo came up with suggestions that we (or very likely HVAC contractors) were clearly not considering, both on home sealing and new system configuration. Alfredo is just a plain nice and helpful person. And we appreciate his guidance. We feel we can now go into our HVAC project with peace of mind that we'll be requesting quotes for the right kind of system for our home. read more

We have been experiencing many seasonal temperature fluctuations in our home, sometimes unlivable and never understood why. We finally decided to do a home energy audit and Alfredo walked us through every inch of our house. Turns out our house is like Swiss Cheese. We would have never known where to start without their service. I'd also like to add they give their honest recommendation that makes sense that will net the most effectiveness in your home with keeping a budget in mind. Would recommend Alfredo and his team to anyone looking for guidance on how to make their home more comfortable. read more

I was getting tired of high energy bills particularly in the winter. Many of my colleagues had recommended ELEM3NTS so I reached out to Alfredo for an energy audit. After scheduling for the audit, he came out to our home, measured our furnace's blower, checked the ducts for leakage and took some thermal images. Alfredo produced a comprehensive report that gave us a clear list of items to address as well as sorting them by priority for easy wins. In the end we walked through the report over a phone call where Alfredo helped explain each issue he found as well as going through some recommendations as well as discussing the potential financial impact. All in all, I'm very satisfied and it's clear now what we need to address in our home in terms of improvements. I highly recommend this energy audit by ELEM3NTS to everyone who is looking for a starting point to improving energy efficiency and to understand the major contributors to your current energy bill. Every home will need a custom solution, but you need to start with an audit to know where to begin before you can start tackling those problems! read more

Alfredo and his team offer a valuable and unique service that should be considered for everyone interested in increasing the efficiency and safety of their homes. Alfredo thoroughly investigated possible leakages in our home through a highly personalized and meticulous approach. We now have an idea of how to increase the efficiency of numerous aspects of our living space. Huge thanks to Alfredo! read more

Afredo and his team were amazing. Great communication, extremely professional and efficient. We had a high heating bill (natural gas) and got incredibly detailed insights and recommendations for how to get the most bang for our buck if we were to do improvements. We're looking forward to taking action based on his recommendations, and feel confident we have a clear picture of our home's overall energy efficiency. Looking forward to making changes to save money, increase comfort, *and* be more sustainable! P.S. They can help you get the instant rebate from BayRen on the audit. There's also a federal tax credit for energy audits available (up to $150, depending on your tax/income situation). Highly recommend! read more

Alfredo and team were fantastic!! We have an old home and didn't know where to start when it came to improving our efficiency. His testing was incredibly thorough, and he spent a lot of time going over the results and his recommendations. It gave us so much more confidence in making decisions about where to spend our money. Plus, the contractors we worked with were familiar with his work and it made it so easy to get the right services done. Highly recommend this team! read more

The Elem3nt's team (Veronica, Jeremy etc) were professional, friendly, efficient and delivered top notch customer service. They always arrived earlier than quoted and completed the job (HERs testing and Home Energy Rating Assessment) on time. Also they always answered any questions that we had and made sure they did everything they could to get use the rebates from BayRENs. They are fantastic communicators and always followed up on every little detail. When working with Elem3nts , we know things are in good hands. It's difficult to have such a honest, reliable company nowadays that cares about their customers interest. Wish there were more companies like Elem3nts. Will always remember the sincerity in Veronica and Jeremy helping answer all of our HERs testing questions and getting the work permits closed. It's already tough dealing with the city's long tedious permit process. Keep up the great customer service Elem3nts and Thank you so much ! read more

Elem3nts did a great job in helping me understand where the problems existed within my property's HVAC system. Alfredo and team cares about what they do, arrived right on time, and explained things very well. read more

I've done two energy efficiency assessments with Alfredo and team - one in 2015 for my previous house and one just now for my new house. Both times, Alfredo provided me with useful information and meaningful advice. I've completed the work he suggested in my old house and it made a meaningful difference in terms of increased comfort and improved energy efficiency. I plan on following his suggestions in my new house as well. I highly recommend ELEM3NTS; the fact that I've used the company's services twice speaks for itself. read more

Alfredo at ELEM3NTS performed a whole-house energy assessment for us in late September this year. Overall, we are extremely pleased! We have an old house with old appliances and knew we needed to make some improvements to insulation and the HVAC system, but weren't sure where to begin. On top of that, we're interested in improving our energy efficiency and decreasing our consumption, and needed to find someone who could assess the entire home as a system and make us a comprehensive, well-ordered plan for how to get to where we want to be. Alfredo was that person. He and his team came and tested our home for airtightness, heat retention, HVAC system efficiency, and more. They brought specialized equipment, performed an entire battery of tests over a few hours, and later delivered an extremely detailed and comprehensive report that included all the measurements and how we compared to the average home. The report gave us recommendations in every area we were wondering about: air leakages, insulation, heating and cooling equipment and ducting, windows and doors, and the potential for solar - we even got recommendations for how we could upgrade our lighting and water systems. Not only did Alfredo provide us with a comprehensive report, he also followed up with a phone call to explain it all in detail and answer all of our questions. He also shared additional resources with us about PG&E energy rebate options, and a list of HVAC contractors for us to consider. All in all, we couldn't be happier - we're now on the path to creating the cozy, efficient home we've been dreaming of. Thank you Alfredo and team! read more

Signed up with Alfredo after seeing these great reviews. Believe me, this is the best $ you will spend. Do you ever go take prescription medicine without diagnosing what ails you? And yet, when we have a problem with home discomfort, or high energy bills, what do we do? We go talk to an HVAC person who will sell you HVAC, or WORSE, a Solar person, who will try to convince you that you are GOING TO save $ IN THE LONG RUN. NONSENSE. Sign up with Alfredo. He is a home doctor who looks at the WHOLE SYSTEM, not just one piece in isolation. The analysis of our house was excellent and even the tests and report is only 50% of the value. The main value is in speaking with Alfredo after he has the report ready. He gave us practical advice and ways to save money without breaking the bank. e.g. I was thinking about putting spray foam into my crawl space and Alfredo explained why it isn't the best place to spend $. The insulation contractor he referred to us is excellent as well, and advised us on how to save $ and obtain rebates from PG&E and BayRen. START with energy analysis. Seal up your house. Then get advice on what to fix - Insulation, HVAC, etc. AND THEN AND ONLY THEN look into big $$$$ items like Solar. You might end up adding Solar (like I will) but you will be way more informed and can spend WAY WAY LESS than you otherwise would have. read more

Alfredo is very knowledgeable about improving home energy and efficiency, and I had a great experience working with his team to compile a home energy audit for my 1960s home in San Jose. His team arrived on schedule and worked quickly to collect measurements, and Alfredo turned this into a prioritized list of recommendations to help my home go green and save money. read more

Alfredo and his group are extremely professional, very knowledgable in their field, extremely responsive to emails and also very accommodative. They made a very thorough assessment of our home energy issues, gave us a comprehensive reports, never pushed us to do any repairs, but patiently guided us to find the right set of repairs for our home. read more

Couldn't be happier with the service Alfredo and team provide. We've lived in our 100+ year old house for about 3 years now: it's soooo cold during the winter (even with the furnace running non stop) and sweltering on hot days (no AC). We've resorted to blankets and multiple space heaters for the winter; a portable AC unit, 3 ceiling fans, and 4 box fans throughout the house as a bandaid for the summer. I finally decided to do something about it (now that we have our first child) and found that PG&E will provide rebates for doing some of this. This is how I initially came across ELEM3NTS-E3 Alfredo and team did a thorough analysis (really impressive to watch, I suggest observing them as they do the tests, it's shocking to actually *feel* how poorly sealed our house was when they did the blower door test). The tests were thorough, but even more impressive was the one hour follow up call where the results were explained with really helpful analogies and recommendations. The fact that they're an independent company means they don't have any ulterior motives (ie not trying to get you to take on an expensive follow-on remodel with them). Alfredo recommended the best bang for the buck and even provided very reasonable personal suggestions (eg, if you don't intend to live in this house for longer than ~5-10 years, maybe this isn't a good investment for you). Without a doubt the best decision I've made so far with regard to this house. I feel much more educated/confident/prepared to talk to contractors about exactly what I want/need. read more

We did an energy assessment of our newly purchased home with the team at Elements. Could not be happier with their service. They were professional, arrived just when they said they would, took just as long to complete the testing as they said it would, and got back to us with a full report even faster than they'd said they would! After sending us the report Alfredo set up a time to go over it together in more detail. That consultation was so useful! Alfredo is obviously extremely knowledgeable. He welcomed all questions and answered everything clearly and in a way that I was able to understand (despite my lack on knowledge of the subject in general). I left that consultation knowing exactly what I needed to do to improve our home's efficiency! Would definitely highly recommend Elements to everyone moving into a new living space! read more

Highly recommend Alfredo and his services!! He can definitely help you save money and make your home more efficient. You're doing yourself a disservice if you don't hire him!!! read more

Alfredo and his company ELEM3NTS-E3 completely exceeded my expectations. I'll admit I was a little hesitant soliciting services for any home auditors for fear of being overwhelmed, misdirected or left with few options. Alfredo and Kyle completely put those fears to rest. They are true professionals. They called me in advance prior to arrival, arrived on time and were incredibly friendly and professional. Unlike other experiences I've had with other services they kept me involved with the process allowing me to learn and understand every step they took, why it was important and how it would help us prioritize a plan. Honestly they are the kind of guys that would make great friends outside of their services. After a complete and thorough review of the home Alfredo emailed very thorough reviews of the home with list of priorities to improve its efficiency. He then scheduled a phone call where he spent an hour going over each point on his review, providing his insights and recommendations and finally explaining who I can contact to get the work done. Prior to contacting Alfredo I spent a few days researching improvements, rebates, contractors and it was a bit overwhelming trying to organize all that inconsistent information with timelines and priorities that would improve our home in the most effective way. Alfredo completely simplified that process with a clearly defined plan, cause and effect of such plan, cost and avenues to get it started. I definitely recommended his services and feel confident I will see positive returns and savings for my home. Thank you! read more

Alfredo was really kind and helpful during our audit on our new home. He spoke with us at length about our options and the most efficient way to proceed. He also provided a long list of recommended HVAC professionals. His report was helpful and very clear. Would definitely recommend. read more

ELEM3NTS is a great company! Alfredo Baccari came out to our home 10 years ago and gave us a very through Energy Audit. Then he was willing to meet with us to recommend our next step in making our almost 100 year old home more energy efficient. Now ten years later I finally reached out to Alfredo to discuss his recommendations. He did not miss a beat. With our audit in hand, he recommended a good process and companies that we could check with to help us accomplish our goals to energy efficiency. Highly recommend this company. read more

I don't often leave Yelp reviews but felt I needed to chime in. Today (a Saturday) I was called by someone at Elements wanting to know why I left a one star review. When I said I did not, he told me that he had the review "right in front of him". Problem is, I didn't leave the review -- I just happen to coincidentally share a first name with someone who did. Truly unbelievable, unprofessional behavior. I am in a bit of shock. read more

Just had my energy assessment done with Elem3nt. The team is very professional, showed up on time and did an excellent job. The downloadable pics and files are very useful. Two tips: 1) Stay around during the process if you can (it takes about 4 hours), because Alfredo might ask you some questions. Also, he can explain what they found on the spot. Sometimes it is just easier to have him point out what the issue is (he will have a phone session with you at later time, but it is easier to have a prior visual image of the issue) 2) Live in the house for more than 12 month. I rented the house for most of last year and year before (I lived in TX for most part of the past two year). Although I lived in the house prior, but it is hard to compare energy saving if different people lived in there the prior year Very good company and team to work with, highly recommend it. read more

I had no idea what I was getting myself into when I applied for a permit for my new A/C with the City of San Jose. Thank goodness Elements was recommended to me for my HERS test. Along with doing a great job of getting my HERS test complete, I got the huge benefit of Veronica, their office manager. Veronica basically walked me through the application process. She very kindly and patiently answered all my phone calls and my emails and made me feel like I had a friend in the business who understood the lingo and confusion that seems inherent with the process. I truly appreciate how much she helped me and would not hesitate to recommend this company to anyone. read more

Worked with Alfredo and team to evaluate my home. The ROI has been great. Their first suggestion alone had a 10 month payback for their service. if I were to count the other items they suggested for cutting down on energy costs, I'm sure it would be well into the six months or less range for payback! Smart and knowledgeable, the team is respectful of your home and family running around! Would highly recommend this team.... read more

We have made a lot of improvements to the house but noticed that our HVAC system seems to work more often than we would have expected. Asked Alfredo to come do an evaluation of the house to help us figure out what we could do to improve our house efficiency especially of the HVAC system. Alfredo was able to diagnose our HVAC system was not drawing enough air, and had quite a bit of leakage! Highly recommend Alfredo and the team. read more

Every homeowner should get an energy audit. In most cases, I bet the results would be eye-opening. After moving into my home for a few months, I knew there were some issues. Some rooms felt cold, there were drafts, etc. But when Alfredo & team did his audit and showed me the results, I was blown away. In no particular order: * The central air ducts leaked 30% of the air going through them * The return airflow to the furnace was much less than needed, which starved the furnace and led to increased leakage of conditioned air into the attic. * The furnace was 66% oversized, which led to discomfort and energy waste. * The house leaked air like a sieve (typical for homes of its age). What I especially liked about ELEM3NTS is that it's a independent company doing your audit, not the HVAC company, so they're less likely to be biased in recommending work. And Alfredo will go through the audit with you in detail, lay out all the options, and prioritize them based on potential future energy savings and health considerations. Example #1: He pointed out that the crawl space access in my daughter's room was not weatherstripped and didn't fit right, allowing crawl space air to flow into room, thus explaining the weird odor that I hadn't been able to find the cause of. Example #2: Did you know that energy savings won't really pay back the cost of replacing windows? A much more cost-effective measure to take is to air-seal your home. As one of the other reviewer recommends, I'd also recommend being present during the audit, so you can see for yourself the issues that are uncovered (Alfredo will include photos in the report, but better to see it first hand). After having the audit done, I engaged Residential Heating & Air Conditioning -- see my separate Yelp review -- to install new ductwork and furnace and fix the crawlspace hatch and do air sealing. Alfredo then came back to do the post-work testing, which showed that the new ductwork didn't leak, the airflow of the system was proper, and that air leakage was reduced by 25%. The house already feels more comfortable, and I look forward to seeing lower energy bills this winter. Plus I qualified for a $2000 BayRen energy efficiency rebate. Thanks Alfredo! read more

We live in an older Sunnyvale home and had several cold rooms in the house. As well, our heating bill was getting a little out of control. So, we decided to get an energy audit. Alfredo from Elem3nts was quick to reply to my request, prompt in arriving to discuss our needs, punctual in arriving to do the evaluation, gave a detailed breakdown of our energy situation. We have already implemented many of the changes he recommended. The house has been much more comfortable this summer. We needed the AC much less. I'm not sure what will happen this winter with the heating bill, but I'm hopeful it will be much lower. Oh, Elem3nts also handle the retest and filing for the rebates we qualified for after we upgraded the insulation. Our check arrived exactly when Alfredo said it would. The full audit with pressure test ran $1200, but was worth it in my opinion. And rebates on the insulation work more than covered the expenses of doing the test. Highly recommended. read more
