I was a new homeowner in 2022 when Vic (the owner) and his company, Elite Comfort Systems, saved my family (including the feline members) from sweltering in 100+F degree weather by diagnosing and repairing my air conditioner. Since then, they've serviced the almost 22 year old system at my home, nursing it along. With each semi-annual "check-up" service, they advised me on what I needed to do, and what could wait. When funds were tight, they suggested stopgaps to help. Because of this history, when Alex showed me that my heater was leeching carbon monoxide into my home, I knew I could trust him. While I waited for my appointment, I was provided with space heaters gratis. This IS an independently owned business, and they treat customers like family. Ozzy (Osvaldo) and Anthony installed a new heat pump and air conditioner for me last week. They were at my home three days. Not only were they professional, friendly, and polite, they were also respectful of my home--taking time EVERY day to cover my carpeted areas, covering their boots as they came into and exited the house, and cleaning up any installation debris before they left each day. Ozzy and Anthony discovered that a part of the original system was not going to work as efficiently with the new system (the dampers) given the difference in the size. Ozzy explained the difference to me, noted the cost, and the pros and cons. He didn't pressure me to upgrade the items but he made sure I had enough information to make a decision. At the end of the installation, Ozzy took the time to show me how to use the new digital thermostat controls and gave me tips on how to use the system economically. He provided me information on how to follow up if there were ever any problems. Just like other times, Vic called a few days later to see how things were going (I missed the call, but still...so so kind and thoughtful). It's a lot of money to replace your entire HVAC system, no matter which company you use, but hiring one where you know you can trust the company. Simply put, you'll never have worries about trusting Elite Comfort Systems. read more

I installed a unit, but apparently I didn't ferrule my lines very well, and it lasted a week. (the old lines from the previous Chinese unit were 6 inches of copper soldered to aluminum to 6 inches of copper, which gives 4 more places to leak so I didn't use them; that unit's motherboard failed.) They wanted $4,169 to fix my lines (new ferraled lines from the manufacturer are $150, and to refill ($125 in freon) total job one hour for me To redo everything, $8,929 I recently installed in my 2,400-square-foot home a whole new heating and AC system for $24,000. They also wanted to redo my 115 volt lines to 220 volts. This system does NOT run on 220 volts. He mentioned how it uses less electricity. NO, it does not. I'm an electrician. 115 volts, 20 amp is the same as 220 volts, 10 amps because 220 volt is 2-115 volt lines, which are 10 amps each line = 20 amps. and he said my water drain wasn't installed properly, but it was according to the manufacturer. (just drain it outside, period.) My unit from 'Heat and Cool' was only $400 without the AC lines; this is the 4th unit I've installed and only one that failed my installation. it comes with a 1-year warranty, 5/7 if you get an ac guy to install it and 7/10 for an extra $150 Well, Elite isn't going to slap their sticker on this unit, so they will lose future business. That's NOT good business; that's simply greed read more

I give Elite comfort systems a 5 star rating because of their technician "JR" ability to repair and explain my problem. I can say without hesitation if you receive a repair from JR you will be satisfied in every area of his service! Mike M read more

Elite HVAC June, 2025: installers Osvaldo and Logan removed and replaced our old hvac system with a premium amount of respect for our home and floors. They completely covered our floors prior to any interior work, worked without music blaring. The outside work was both clean and professional looking at completion. They vacuumed inside, cleaned up outside and removed all evidence of their two-day presence. They provided what we considered extra touches of effort and attention to the job. read more

Elite Comfort Systems - new hvac - Heating & Air Conditioning/HVAC Near Me - Brentwood, California

They still reach out trying to get our business despite the terrible experience we've had with them. Also, here's a tip--don't tell a customer to contact you to make things right. Do the work and contact them to make things right. Clearly you still have my name and number on file since I'm getting messages telling me to sign up for maintenance. read more

I had Elite Comfort Systems come out and perform a deep health check on my HVAC system. The value of their service far exceeds the cost of "not knowing" the condition of your system. I worked with Joshua, who was a stellar agent and a wealth of knowledge! He found a small wiring issue that would have never passed a thorough inspection, which my builder had missed during the setup. Because of that, I was able to get it repaired and can now rest assured that the power and overall health of my HVAC system is in tip-top shape. Thank you, Elite Comfort Systems and Joshua! I will surely be back! read more

Elite Comfort Systems recently replaced our outdated gas furnace and air conditioning with a new all-electric heat pump system. The two-day installation was smooth. Ozzy removed the old furnace and placed the new system on the first day. The following day Anthony and Giuseppe finished the remaining work while Alex oversaw the project. They were all so knowledgeable and well trained that they made a complicated job seem effortless. So far, the temperature in the house seems more consistent without hot or cold spots. The coming winter months will be the real test. The system is controlled either by the thermostat or via smartphone. Additionally, the zero percent 18-month deferred interest rate financing option was a significant factor in our decision to go ahead with the new system. The team was well organized, polite, and courteous and left the area neat and clean. The installation was an all-around positive experience. Thank you, Alex, Ozzy, Anthony, and Guiseppe. Thank you for providing us with a more comfortable home environment. read more

The service I received from Alex was 5 Star! He was punctual, called before arriving, clean, explained everything he did. He even offered to hang a Christmas decoration for me. As a homeowner, I appreciate the biannual service I receive from Elite. read more

We needed our dryer vent cleaned out because who knows if it had ever been done in the history of us living in the home. Elite comfort systems sent out Robert who was very prompt, friendly and professional. He was in and out with the job completed quickly. Very pleased with the work and value! read more

*****UPDATE- I received a call from Victor and am satisfied with how he handled this situation. His main concern was to make it right, and I appreciate him following up. You can tell he cares about his customers. I changed my rating based on his customer service! Original message: The technician replaced a part that was old, not broken. Ultimately, he did some work and my air conditioner was still not working when he left. Before the technician replaced said part, I asked him to look at the "high pressure cut off switch". (Thinking that was the issue.) He said he had "never heard of that part" and assured me that it was a different part that needed to be fixed. (It was a red flag that he had never heard of that part before, but I was desperate because it was 102 degrees so I let him continue.) I have been trying to hear from a service manager for 2 weeks now, and have not received a call back. read more

Robert and Alex showed up to the service call in a timely manner. Alex did most of the servicing, he explained what he was doing and based on the age of the unit and what he observed, gave us his recommendations for servicing and repair. Of course our unit was on its best behavior when they got there but Alex explained how the furnace and AC Unit work in tandem and what may have potentially made the crazy sounds. He was very fourth coming with educating us and answering our questions. Upon arrival both Alex and Robert wore masks and when Alex entered our house to check the furnace, which is located in the Attic he immediately wore booties on his shoes. They came for a service call, did a unit check-up, educated us and answered our questions, we're first time home buyers, so there were a lot. We felt they weren't pushy salesmen that were trying to milk us for every dollar. They assessed our situation, let us know what our current situation was, suggested some repairs and maintenance to help prolong the life of our unit. Then left it up up to us to decide, no scare tactics or high pressure sales. Thank You Elite again for addressing our concerns. And we'll see you in the fall. read more

Elite Comfort Systems - Service Van - Heating & Air Conditioning/HVAC Near Me - Brentwood, California

See all

Overpriced, you tell me. We had a control panel fail on a newer furnace that was still under warranty(3yrs old). Actually Elite installed the furnace. The control panel was covered but not labor. We were not charged for the part but 1 hour of labor cost us $856. Half hour to replace the part and another 30 minutes to test the system. The service was good but we felt the amount was excessive but you can decide for yourself. We were long term customers but will now shop around. read more

I couldn't be happier with Elite Comfort Systems! Of course my AC decided to break down in the middle of a heat wave and the raging California fires. Robert did an excellent job fixing our AC. He was on time, fast, and knowledgeable. I can't think of a single thing to improve on. I'm now sitting in my nicely air conditioned house while the nasty smoke remains outside. Our lungs thank you! read more

In July of 2022, our AC condenser failed putting us (most importantly, my wife) in an exigent and precarious predicament. It may seem off topic, but it's pertinent. My wife's demeanor is more susceptible to temperatures than a persnickety elderly lizard. If she's subjected to temperatures on either side of a 10 degree range, our chances of divorce skyrocket immediately. Without getting into the particulars of why this is, I will get back to my review. Just know this. With much haste, I scoured the internet looking for a reputable HVAC company to replace our failed condenser. Elite Comfort Systems was a shoe in as they obviously have great reviews and much experience in the area. We made the necessary arrangements and the technician arrived on time. Prior to the technician's arrival, I had gone in our attic and assessed things. I used my observations to describe our predicament to the technician. The technician decided he would have a look for himself and went into our attic unaccompanied. He later came down and suggested a whole laundry list of repairs. At the end of the list, he asked if we were experiencing leaking coming from the ceiling. To which I said, no. He pointed to an area on the ceiling and said "this is leaking." I observed it. Visually, the area the technician was pointing to was identical to its surroundings. I felt the area and it was dry, not damp, to the touch. I didn't argue with the tech and didn't think much of it at this point other than he has poor sensory skills. I made arrangements with him to conduct the repairs and he said he would be in touch the following day. I impressed upon him the exigency of this situation with regard to the aforementioned scenario with my wife. This in mind, he assured me he would let me know when all the parts were available to conduct the repairs. We were charged $100 for this diagnosis. Before going to bed that evening, my wife alerted me to "water" coming from the ceiling. After the customary onslaught of explicits, I got out the ladder and went in the attic. The source of the leak was readily evident. The PVC condensate was clearly broken. Not only was it broken, the break was just above the spot the tech had alerted me to and inquired about earlier. I thought to myself, I was just up here and I would have seen this. However, I can't say and won't say if this damage was here prior to the tech's arrival. Anyway, this required me to jerry-rig a garden hose onto my wet dry vacuum and suck out the entire condensate drain pan at midnight with an angry wife. The following day, my wife, dreading another 100+ degree forecast without AC, called this tech. After multiple phone calls, the tech was repeatedly unresponsive despite having a mobile phone and it being during business hours. My wife finally called the office number of Elite Comfort Systems. The office manager even had a difficult time tracking down this particular tech. They eventually got through to him on the phone and he called us. He had some sort of excuse about how he had been working on another job and couldn't get around to calling us. Mind you, he has a cell phone. At this point, I was thoroughly annoyed and highly suspect of this person sabotaging our condensate line to ensure Elite Comfort Systems got the job. I told my wife to tell this person we won't be using their services. Suddenly, he got defensive and was immediately available after hearing this. His sudden change in demeanor was very indicative that he was just jerking us around with regard to his availability and not on par with the level of professionalism I expect coming from a service provider that I'm contemplating paying $5,000+ to. Ultimately, my wife was able to get off the phone with this very confused and shocked individual. We later went with another HVAC company that gave us no problem and was reasonably priced. In case you are wondering, my marriage is still intact. Let me make this review clear. I am not definitively saying an Elite Comfort Systems employee sabotaged our AC system. However, I was curious, so I did some math for those of you who are also curious. The construction of my home was completed in March 2012. I discovered the broken condensate line on July 28, 2022. This breaks down to the line being in service for 90,832 hours without a visible leak. The time from when the technician went into the attic only to come down and ask me if I had seen a leak to the time when I did see the leak was approximately 10 hours. This breaks down to a 1 in 9,083 chance of the technician's story being the case. I have included photos of the damaged condensate as found after the technician's visit to the attic. It certainly appears that based on it's condition, it was subjected to a force not normally occurring in a vacant attic, i.e. a person pulling on it, rather than natural wear and tear factors, i.e. temperature variants, house settling, etc. read more

Highly recommend Elite. Robert was very professional, wore foot covers in the house, communicated through entire process of having attic fan installed. Took before and after pictures and showed us to operate on iPhone app. Great job and will definitely be using in future for all hvac needs. read more

Can you believe my AC decide to go out at 9pm the night before the following days were set to hit high 108's? The audacity lol. Luckily Elite Comfort Systems came through for the save! I made an after hours call that same night, left a message regarding my dilemma and received a call back first thing in the morning. They were super generous in accommodating me that very same day and had a technician out to my place for an estimate in no time. I was utterly impressed and so thankful considering this is wild fire season and every HVAC business must be swamped with calls & appointments. My technician Victor was amazing. He showed up on time, promptly assessed my AC's issue and wrote me a fair and honest quote on the spot. I was ready to spend an exorbitant amount of money considering the peak season the level of service provided thus far but Victor being a true professional and fair ( I came to find out) business operator made the price very reasonable and the whole experience a pleasurable one. I happy to report that my AC is up and running strong and steady. I would highly recommend Elite Comfort Systems and cant' thank them enough for saving my behind in a pinch lol. read more

Elite Comfort Systems - Super Hero Victor Gewondjan moments after he fixed our broken AC unit - Heating & Air Conditioning/HVAC Near Me - Brentwood, California

I called to get AC checked as it was not working properly. I made an appointment for 3 days out (104 current temps!) and he said if there's a cancellation they'd call. They arrived within hours of my initial call, same day! Yes, I got lucky and am grateful. Robert came out, checked everything, did the fix and we added a maintenance service too! All done swiftly and pleasantly. I asked 100 questions and was probably annoying but he answered them all with friendly attitude. Even with my little dog barking incessantly at him, he was great. Thank you! Amy read more

The sales rep answering the phone told me they have same day availability. Noted down all my information, said I'd get a call back in a few min. Got a call back about a couple of hours later and was told the soonest availability is in 5 days. This is just shady practice. read more

It is well known within the heating and air conditioning industry that the quality and professionalism of those installing the system is more important to a successful and long-lasting installation than the brand of product selected. (This is because just a small handful of manufacturers build equipment for all brands). From the moment Ozzy and Logan stepped out of their Elite Comfort Systems van, I knew that I had the right team working for me. They were clean, polite, motivated, and eager to get to work. They were highly knowledgeable, and worked together. Their vans were well equipped with everything needed to efficiently and professionally install my new system. Not only did the work proceed quickly and cleanly, but they were happy to go beyond the normal installation steps, and satisfy some special requests that I asked for, (such as excavating the area where the air conditioner pad would be located, in order to bring it down to sidewalk level, and, reinforcing the gas lines with additional 2x4 bracing). Thanks, guys! On the final day, it looked like wind and rain might delay hooking up the condenser, which was located outside. Douglas took it upon himself to work on his hands and knees, outside under a tarp, in order to complete the job and ensure that I would have heat that evening. I appreciated that. Overall, I am completely satisfied with the installation of my new heating and air conditioning system, and would recommend Elite Comfort Systems without reservation. Chuck C. - Brentwood, Ca. read more

I would definitely recommend them. They were quick and so far the new unit is working fine. Alex the tech has been very helpful. He was very caring of my situation. I will be keeping them for any wore I need in the future plus yearly maintenance. read more

We had our first contact when the estimator came to our house. He was very personable but even more impressive was his depth of knowledge on HVAC systems. We had multiple estimates at a range of prices and only this young man was detailed and confident of his estimate. After reviewing the completed written estimate, the price, and the timeline we signed a contract. The installation crew of three was friendly, efficient, and dependable. This is a complex task that went down without a hitch. We contacted the City of Oakley and secured a permit. There was multiple steps to get through the permit process and with the help from Elite we were signed off and finished soon after the installation. We are very satisfied with new system and thankful we chose Elite read more

We contacted this company to see about a moving our existing AC to the side of the house. Vic came out and met us to discuss, and answered all of our questions, there was no pressure to purchase, he gave us solid and honest information, transparent quotes, what to expect when moving a 20+ year system etc. We were immediately impressed his honesty and professionalism. He answered all of our questions and on top of it all, was kind and respectful. Moving forward a few months, we decided to replace our AC, set up an appointment to do so, and encountered a snag in the project. There was a crack in our furnace. When they came to it, they provided pictures, explanations, safety guidance, and more. Robert and Ozzie were are main technicians on site. There were with us for 2+ days in our home. Were incredibly respectful, transparent with their work and what they were doing, communicated, and we absolutely have nothing more to give then just praise for them. We ended up having to replace our furnace and by choice our AC, but they were honest with their pricing and procedures. Information was freely given. And most importantly, this company was incredibly respectful to our family for installation. Wished all companies were more like Elite Comfort Systems. From the first call back, we were impressed. Very thankful to Vic, Robert, Ozzie, and the entire team. read more

During the heat wave my air conditioner was not working properly. It was time to replace with a new unit. Logan came out to bid on a new comfort system. He was very knowledgeable and professional. I appreciate the time he spent giving me a thorough understanding of how the system works and what to consider for the best efficiency. read more

Customer Beware!! I called Elite for my air conditioner not working and a tech arrived and met with my wife who was at our residence. The tech told my wife that a electrical component went out on the system and it would be a $300 part plus service fee. My wife asked for the broken part and it was a $15 capacitor. I called the owner and explained that his tech was deceptive and took advantage of my wife. The owner threatened me to have his tech return and take the new capacitor out. I told him to take it out. I went and purchased a new capacitor for $15. I requested a refund for the $300 part and he said it would be credited to my credit card. After a month, I did not receive a credit and I had to call the owner again and demand my money back. These guys are straight criminals! Do not trust them at all. I have attached a copy of the receipt. The only mistake I made was calling Elite Comfort Systems in Brentwood. To deceive a lady with two babies shows the true character of the tech and the owner. I already told all my neighbors about what happened and this company will not be getting business in my neighborhood. read more

I couldn't have asked for a better customer service experience from him! Took care of everything we needed, mainly the dampers, and was extremely professional and personable. Can't recommend them enough!! Thank you again!! read more

Scheduled appointment a few days prior but they were unable to make it due to how busy they are. To their credit, they are responsive & knowledgeable. Unfortunately I took half the day off for the appointment and couldn't wait later than my appointment time. They did apologize and offered to reschedule but I don't have time available at the moment. read more

Of all the HVAC people I've encountered, Alex is the only one who was willing to give me real explanations about what the issues were and answer my questions in a patient and intelligent way. I also cannot say enough about the crew! They were professional and absolutely top notch. I didn't note their names, but Alex please thank them for me! Btw, My new AC bill was $500 this time last year, had risen to $800 this year, and has dropped to under $400 with the new system. The savings make the cost of the new system a no brainer! I can't thank you enough! I just wish I had called you sooner :) read more

Lead tech Logan Justice was prompt clean and very skilled. A+++ it was well worth $149 to do all the checks required. I had no idea that a 10 by 10in filter in attic needed replacement. Very happy first time customer Setu Hawkins Trilogy in Brentwood read more

I called and spoke to Victor after 8pm on a week night. By early afternoon the next day, he had sent technician, Kieanta. Kieanta was very professional, honest, and very thorough. He walked us through the entire process of what was needed to repair my air conditioner. He got my system up and running in less than an hour. We signed up for the company's service plan, which is very reasonable compared to other companies we had spoken to prior in the week. We highly recommend Elite Comfort Systems. Ask for Kieanta, he's Awesome! read more

Vic and his team really do a great job. Whether it is a service call or a new install, they are very clear about what needs to be done and give you a fair estimate of the cost. Recently they put in a completely new system in my home and they did the job in a reasonable amount of time and the installation was done very professionally and cleanly. The system is running great and it was just in time for the temperature in Livermore to hit 99 degrees. Would recommend Elite Comfort Systems if you need your HVAC serviced or you need a new system. read more

Our air conditioner went out on Saturday. And it was a three day holiday weekend. Right in the middle of a heat wave. And the upcoming week showed NO sign of relief from the sun monster. I have called Elite on Sunday evening, hoping to get service out on Tuesday. To my surprise, Vic was available on Monday (Labor Day) and came out to fix the problem early morning. He was very helpful, knowledgeable and reasonably priced. He arrived right on schedule and got the job done. I truly appreciate his honest business and being straight up front with us. Thank you, Elite! I totally recommend Elite Comfort Systems ! A great local, family owned company that you can rely on. read more

Great service, highly recommend for your air conditioning needs! Their first availability was one week out and because it was so hot in Brentwood, they ended up coming out the same day due to the extreme heat and no cool air blowing into the house. Logan was very thorough and fixed the problem within a couple of hours. It was nothing major, but he was able to get my system all cleaned up and running properly again. read more

I am new to Brentwood and was looking for a local HVAC contractor and came across Elite Comfort Systems via Yelp, Nextdoor, and Google. I hired them to do a routine maintenance/tune up of my 5 year old heater system. As a homeowner I am a firm believer of having a basic understanding of your systems and to ask questions of your contractors to gain a better understanding and to know what you are or will be paying for in the future. Although nothing was apparently wrong with my heater, preventative maintenance was the goal. Alex was very transparent and essentially gave me a crash course in HVAC while performing maintenance on my system. He explained the components, function, and what to look for. He also identified that the gas pressure was too high causing the system to shut down and reactivate prematurely. When all was said and done, my heater functions much more efficiently, holds temperatures longer, and only comes on when needed (I'm sure my next gas bill will reflect that). I plan on using them again in the spring to perform the same service on my AC unit. read more

Logan came out and performed our heater fall service, and again he was outstanding. (He was involved with the repair of our heater coil and installation of air conditioning compressor) very knowledgeable, and explains everything completely. a great work ethic and attitude! read more

Yesterday we came home from a week's vacation. It was over 100 degrees and our house was approaching 90. We were horrified to find out our air conditioner was down. I reached out to Vic and he said he would call me back. He called ten minutes later and said he was on his way. He jumped on our air conditioner and it was fixed very quickly. Vic was awesome! Him and his team are very professional and punctual! Needless to say I'm sold! Try him out! You'll be amazed! read more

Most of the time when you have your AC serviced, you dont get a full run down on what was the exact issue, and how that issue was resolved. With Kieanta, everything was full transparent and got to learn a thing or two about ACs! Also, always nice to have local people working for a local company.
