    I used Energy Core Construction to paint my house. They did a fantastic job. The staff was very responsive and accommodating. The work was thorough and completed on time. I'm very happy with the results.

    Everything from the initial consultation to the completed work exceeded our expectations! Very professional, punctual, and polite! We had them complete our text coat paint job and new windows and 10/10 I recommend! My husband is a painter and he was blown away by the job well done!

    High quality and efficient workmanship. The crew leader introduced himself. He put me at ease by letting me know they are here to make me happy by replacing the windows. He was right. In about 6 hours, all was done. They cleaned up, took care of business and left. I woke up today in a NEW HOME. Photos of one of the windows being installed

    Energy Core replaced most of our windows in September with high quality Anlin windows. We felt the price was a good value for the final product and features. The process was very efficient and didn't damage the stucco. From the sales meeting to the installation, the communication was excellent and the process very smooth. The installation crew was outstanding and skilled and did an amazing job, cleaning up along the way. Can't wait to call them back to get our remaining windows replaced.

    All that was promised was delivered in a clean and timely manner! It was nice not to have to clean up after they were done with the installations.

    New set up !

    You have no idea what a big deal getting Central air in a Mexican household is. My mom loves to suffer through the heat , Not me ! I've literally stayed in bad relationships for air-conditioning and Showtime (LOL) Mike and his three man crew knocked it out in three days. Our house was full of challenges and they work through all of them with a smile.We got along with them so well the last day we made them homemade vegan tacos made with fresh Handmade tortillas . He put everything away nice and clean and worked around all of our stuff . I would give them more stars if I could. Thanks guys #FeelingLikeFonzie #BecauseI'mCool #Literally

    Living room windows look great and keep the heat out.

    Got windows installed on my house and after the installation I noticed that standing near the windows I didn't feel the heat from outside like old windows. The noise has been significantly quite and the house stays cooler even with out having the ac running constantly. Dealing with energy core was also very easy since they kepted us updated on what was going on and when the installation will be started.

I obtained three estimates, and ultimately chose Evolution. I did not regret this choice. Jeff Kieffer came out the day after I called and provided an estimate and a proposed plan, and the owner, Diego Martinez, visited my house twice, once to explain how a difficult room would be accessed and serviced, and the day the work began to answer any final questions and give final directions to the installation team. The process was smooth and efficient: * The team arrived on time, were extremely courteous, and Diego, the owner, showed up and took the time to explain everything clearly one more time. * They handled the installation with care, keeping the work area clean throughout the day. No mess left behind--they even vacuumed up and wiped down areas they worked in. * The crew was knowledgeable, answered all my questions patiently, and made sure the new unit was perfectly sized for our home (no shortcuts or upselling) * They tested everything thoroughly before leaving, walked me through the operation of the new thermostat (Ecobee Premium), maintenance tips, and warranty details. It's only been a short time since the install, but the difference in comfort is night and day. Exceptional financing was offered, and the value of this project was perfect for my budget I also gained a new closet by moving the unit up to the attic! If you're in the Orange County area and need a new AC/heater system, I can't recommend this team highly enough. Professional, reliable, and genuinely focused on customer satisfaction. 5 stars all the way--thank you for making our home so much more comfortable!

    Final update: The company has now stated in writing that they will not send a technician and…read moreadvised me to work with another HVAC company, despite acknowledging the issue may have fallen through the cracks. For context, during this period we had a newborn and significant personal obligations. When the visit occurred, the noise did not happen at that moment and no technician evaluation or adjustment was performed as a result. I later recorded the noise when it occurred and shared video evidence. Despite this, no diagnostic visit was offered. My review reflects both the unresolved issue and how it was ultimately handled. After posting this review, the business responded by disputing timelines and attributing the issue to unrelated work, but did not offer to inspect or resolve the ongoing airflow/pressure noise, despite video evidence. The attic cellulose work referenced was recommended by their team and performed by a contractor they referred. I had an air conditioning unit installed by Evolution Air in 2021. Since installation, the unit has intermittently made a loud "farting" or bubbling noise. I reported this issue within the first year. A technician came out, but unfortunately the noise did not occur during the visit, so nothing was adjusted or fixed. The problem has continued since then. After researching the issue myself, I found multiple discussions on Reddit indicating this is a known and common problem related to airflow or pressure adjustment, and that it is typically an easy fix for an experienced technician. Despite this, the issue remains unresolved years later. Overall, I'm disappointed that a known, recurring issue reported early on was not properly addressed, and that I've had to rely on online forums to understand what should have been a straightforward adjustment. I have recorded a video and sent it as well.

Kirk was FANTASTIC! Our unit is 20 years old, we have never really had regular maintenance on it. He showed up super early (they asked if that was okay, and YES thank you). Before he arrived they sent a text with his name and photo. I absolutely love this! That extra safety is so important. Kirk looked at our unit and asked some questions. He explained all they do with the "family plan" so we signed up. I am one of those that needs to be reminded of scheduled upkeep so this is perfect. He gave us the estimate before he started and I asked for a very rough estimate of a new unit (having no idea) so we decided to go with repair and hope for the best. The repair wasn't cheap but considering all the work that needed to be done as well as it being an older unit, I feel it was a very fair price. I think we did have the best with Kirk. He was able to repair our unit and give it some much needed TLC for our AC unit and furnace. He even installed our pre-purchased thermostat! Kirk was polite and considerate. He took time to answer all of our questions and ensured us that we could reach out with any questions, I believe him. Service people can often be rushed, there is a lot of work out there, but not Kirk. He didn't waste time either, I felt like he was in and out in no time at all. By the time he left we understood all that was done and what we need to do to get some additional service from our current unit. I could not be happier with the call I made this morning. I picked the right people to call!

Jesus did the free cinsultation to address our problem. He did an excellent job representing JMartin throughout the process. He took the time to clearly explain the differences between the various systems and helped us understand why certain options made more sense for our needs. What stood out most was that we never felt oversold. He was honest about what we needed now, what could wait until later, and even what we should avoid doing and why. His attention to detail and knowledge of the products and design process reflected the high level of service JMartin aims to provide. He also identified a concern that other vendors missed, which gave us additional confidence in his expertise and in proceeding with JMartin. He was able to secure a price lock for a project we plan to do later in the year, ensuring we won't be affected by the upcoming price increase. Shay completed our first scheduled maintenance within the promised timeframe and was both informative and knowledgeable during the visit. He communicated clearly, answered questions thoroughly, and demonstrated technical understanding. His professionalism and efficiency reflected positively on the company. Michael and Frankie performed the scope of work. They removed and replaced all of our air ducts, opened up the intake grill, and installed chicken wire in the outdoor furnace. From start to finish, they were professional, respectful, and incredibly thorough. They arrived within the promised timeframe, wore boots and protected our floors, and completely cleared out the attic before designing a much more efficient airflow duct system. Everything was neatly suspended instead of left on the attic floor, and they even replaced all the vents. What really stood out was their attitude and communication. Michael and Frankie took the time to explain everything clearly and patiently answered all of our questions without ever making us feel like we were bothering them. They were always friendly, helpful, and easy to talk to. When the job was finished, they cleaned everything up perfectly and even hauled away all the old ducting bagged up, leaving absolutely no trash behind. That level of care and respect for our home was truly appreciated. I highly recommend JMartin Indoor Air Quality, LLC, and especially the Michael & Frankie team. Outstanding workmanship, excellent customer service, and genuinely talented respectful people. We will also be working with JMartin in the future when it's time to deep-clean and insulate the attic. I am glad we found them!

PUNCTUALITY 7. THOROUGH EVALUATION We met with the following specialists: SEAN O'HARA (AC repair) - AC stopped emitting cool air. Fixed issue w/ filter repair. ALFRED BIRNHAUPL (AC leak repair) - Fixed pipe leak from AC and completed comprehensive assessment of our dysfunctional zoning system. DOMENICK ALONGE (project manager) - Reviewed findings from Alfred, provided detailed indication of issues and resolution options with several quotes. Here's why our experience has been superior to previous companies: All three specialists were not only punctual, friendly, and courteous, but they took their time to evaluate our issues in CLEAR layman terms corroborated by photos, and showing us exactly where the problems were in person. We previously obtained a quote from a large corporate company and was left feeling dumbfounded and stressed as they described the nature of our problem in engineering, technical jargon that made absolutely no sense, including astronomical quotes without explanation of the work entailed. We continued experiencing intermittent issues with our AC and heater so we called Friends & Family based on their excellent reviews. This time around, with Friends & Family, we left feeling knowledgeable and reassured, with reasonable quotes including various discount eligibility. We didn't feel pressured by them to choose one route vs. the other; rather, gained the information we needed to make an informed decision that would prevent such issues in the future. Overall, their attention to detail, ability to explain the issues and resolution routes in simple, concrete terms, were far superior than the preceding company. They exceeded our expectations and we much appreciated their patience and openness to answering all our questions. I also want to mention that I was gardening when SEAN was fixing our AC. He saw me struggling to dig a hole for my plant and volitionally offered to help me. He took the extra time to dig the hole for me, exemplifying his genuine kindness and generosity! Similarly, my kids were running amuck and screaming and shouting while I attempted to maintain a conversation with ALFRED. He was very understanding and continued to engage in conversation, appearing unbothered by the chaos with a pleasant disposition. Lastly, DOMENICK was appointed on the day of our son's birthday. He related to us interpersonally and even helped assemble my son's new Radio Flyer bike! I told him that Sean also helped me garden and we laughed about how Friends & Family is a "one-stop shop." Given everything I mentioned, we're excited to have our overdue AC/heater system fully repaired by Friends & Family. We can't wait for our longstanding issues to be behind us, and we anticipate leaving an updated review once the work is complete!
