We had Comfort Energy install our split AC system several years ago after two other installers said "it can't be done". We are in a townhouse with a connected wall so it proved too big of a challenge for the others. Comfort Energy was extremely professional and we've had our AC unit for years without incident. We do have an annual maintenance plan to ensure smooth running. This time, Agustin came out and he provided excellent service. He's actually the first tech to come out and clean our compressor with a detergent! Usually they just spray water. He also noticed we were missing a pollen filter and suggested the best way to find replacements on line. After the visit he sent us photos documenting everything he worked on. I'll be requesting Agustin again for our annuals. read more

5 stars! Comfort Energy is flexible with their schedule and listens to my issues. Before contacting Comfort Energy, I replaced my filter, ensured the compressor was working, and the fans were on. My AC was still blowing warm. I called for an AC diagnostic and let them know of the current status. I made an appointment 2 days later. The technician, Fabian, called me 20 minutes before arriving. He was friendly and explained to me how the refrigerant was low. The visit was incredibly informative. I highly recommend Comfort Energy! read more

First time working with this company and since working with many vendors, I find that Comfort Energy is one of the best companies to work with for all your HVAC needs. I write this review because I genuinely felt I had the best service and value for my Air Conditioning needs. I recently purchased a condo that had some issues with its A/C. I prefer to let technical experts take the lead and help diagnose and fix my issues. Stephan, Comfort's service technician, was dispatched and was extremely knowledgeable in all aspects of this trade and had a great personality! It was helpful that he went through his diagnostic procedures throughly and provided great analogies and examples to best understand how the system works, which is important for any homeowner. He helped replace my AC Capacitor and filter (blocking air flow due to paint). This resulted in a more efficient AC and peace of mind knowing my AC Unit has longevity. The value for the service is absolutely worth it. I will continue to have this company as my go to servicer. read more

Stephan Reich was fantastic--professional, knowledgeable, and efficient. He diagnosed the issue quickly (about 15-20 minutes) and explained everything clearly. Yes, the $200 diagnostic fee is higher than average, but you're paying for expertise, not trial-and-error. It ended up being a simple air filter issue, and he took the time to explain proper maintenance and system care. Based in Milpitas and services Dublin too. Solid experience and a tech who actually knows his stuff. Would definitely recommend. read more

On time plus I received a call 30 minutes before the Technician arrived. The Technician took his time to analyze the problem while keeping me update. I have an old AC unit but Comfort Energy was able to find the parts and fix my AC. Plus he cleaned up other other parts. read more

I wanted to take the time to give high remarks to Benito and Jose for doing a phenomenal job replacing our HVAC ducting. Benito and Jose communicated clearly between us as their clients and with their manager. They were very thorough and, had a good strategy on tackling the job. They had great suggestions for improvements on insulating our furnace and the quality of their work was top tier. We felt that their final quote was fair and reasonable. Thank you for the great work! Highly recommend Jose and Benito! read more

Comfort Energy just helped us replace our home's 15 year old HVAC system with a modern, top of the line heat pump. I detailed in my request that sound level was a big priority in choosing our system, and our Comfort Advisor Maurice knew just what to recommend - a Mitsubishi heat pump that met all our requirements and worked with our home's existing electrical supply without needing any additional panel upgrades. Maurice was able to get our installation schedule within days of accepting the project proposal, and the HVAC technicians Guillermo and Jose who came to handle the installation did a fantastic job. They not only installed the new heat pump, but also cleaned up parts of our existing connections to make everything was properly covered/insulated. Everything went smoothly, and the end result looked so much better than what we had before. I'm really happy with the entire experience from start to finish and wouldn't hesitate to use Comfort Energy for any future HVAC related needs! Edit: Shoutout to Beto as well who handled all the post-install work needed, including scheduling the inspection with the city to make sure the new install was all up to code. All the communication from him was very clear, and he took care of everything - including personally walking the inspector through everything on the day of the appointment, and handling all the paperwork. All I really had to do was just be present at home, and Beto took care of everything else! read more

I highly recommend Comfort Energy! Maurice did great work explaining our options and providing clear quotes with all costs and work required clearly documented. Guillermo, Dustin, Herbert & Beto did an excellent job installing our new Mitsubishi Electric Mini Split AC system as well as our Rheem Electric Heat Pump Water Heater! They told us what to expect every step of the way, completed the installation quickly and efficiently, cleaned up after themselves each day of work, and helped us understand how to use our units. We got the quality of work we expected at the price that was documented and approved with no hidden costs. Great job, Comfort Energy! read more

Fabian from Comfort Energy did excellent work. Our home furnace went out on Christmas! We had used Comfort Energy years ago for something else years ago and had a good experience so we called them again. Fabian came out right away. Explained clearly what was broken and our options and then fixed it fast. He also offered to (for free) check the Carbon monoxide levels from the system to make sure we were safe. Just great work and I trust him. read more

The service was excellent. Stephan is knowledgeable, caring, and considerate of our home. I recommend Comfort Energy, and in particular, Stephan, for anyone who needs service or maintenace on their equipment. read more

Very nice and friendly, help you to do each steps getting through the processes and rebates. Very responsible and handle everything. It's great to work with them, Beto and Maurice. read more

Steven made special effort to come despite the late hour as it had been colder than normal. He is polite and thorough explaining all the potential issues. read more

Stephan quickly and clearly diagnosed the problem, while also checking for additional issues and ensuring the system was functioning before he left. I felt highly confident in his work, and I learned useful things for proactive maintenance! Terrific technician, and exactly why I come back to Comfort Energy year after year. read more

Great service from start to finish. Sales person Maurice was super friendly, courteous, clear and thorough. He sent me 3 estimates to choose from. Technicians/installers Benito and Jose were respectful, efficient and experienced.The 9000 BTU Gree mini-split I ordered was competently installed in my primary bedroom. I am absolutely delighted with the results and look forward to having a much more comfortable bedroom to retreat to during the hot summer months. I would definitely recommend hiring Comfort Energy for HVAC projects. read more

We worked with Stephan Reich to evaluate our 25 year old gas furnace. He was prompt, reliable, and identified all the major problems with our furnace. Among other things, our filters needed to be replaced and Stephan made it happen in no time. The quotes that we received for future work are reasonable. We look forward to working with Comfort Energy for our HVAC needs. read more

Comfort Energy has been helping me with heating and cooling for years. Recently, I had issues with my furnace and wasn't getting my house heated. Stephan came out and quickly diagnosed the issue, explained it to me clearly and repaired the same day. I appreciate his professionalism, knowledge and courtesy. I highly recommend Stephan and Comfort Energy! read more

We had great experience with Comfort Energy, Big Kudos to the company, to Jaime and Mike who helped us, they're really great! Highly recommended: 1) Very on time! Both inspection and installations, they come at the time they promised, and send messages to let us know that they're on the way. 2) They're detail oriented. They take quality very seriously, install the heater beautifully, handled all the small places (like we used to have water dripping outside and they helped us fixed that). They're very professional and willing to spend time for good work. 3) Jaime and Mike helped us to install the nest thermostat. our wiring is very tricky, we thought we can't install nest. Jaime and Mike explained different options, respect our opinion, and end up with a simple solution to solve this issue perfectly. During the installation, Jaime compare the position very carefully to make sure it aligns perfectly on the wall. 4) They protect our floor whenever they're working, they organize all the wires and pipes beautifully, not just working but also working elegantly. Jaime installed the nest for us, and vacuum all the dust around the area after it's done. All the working area are cleaned up carefully. 5) They take time to show us how it's working, how to operate, they have the right tools to diagnose and verify it's working properly. They're also very knowledgable about this domain and willing to answer questions patiently. We're so happy with them, and really appreciate Jaime and Mike's great work. This literally made my day to have our heater fixed so confidently. Highly recommend them to anyone needs similar service! read more

Stephan arrived on time and got my heater working perfectly. I saw some info on the thermostat that made we very worried that something was not right. Stephan tested and checked everything, tuned it up, and I am enjoying heat again. I would definitely have him out to check my heater again when needed. read more

Maurice came to our home as a consultation. He was terrific. He carefully inspected our current system, listened to our needs and concerns and prepared a quote to replace the Furnace and AC. In the business for 20 years.....Maurice is excellent! read more

Wonderful crew led by Guillermo and Noe (all polite,respectful, and considerate of our property). Always came on time and never left a mess. They installed a wonderful air-conditioning system at an appropriate price. Office staff is also terrific and will bend over backwards to help you. Comfort has previously replaced a blown boiler for my father's radiant heating system. Not many crews around who can still deal with this type of heating. Choose Comfort Energy and you will NOT be disappointed! read more

I've asked them to evaluate how my existing system could be improved, to be able to handle the heat of our summers. I told them several times before that that I know that the existing AC works as intended, but the overall ducting is simply not designed to deal with 110 degrees summers. As the result, then sent a technician to evaluate the existing HVAC system, but he was not the one to actually come up with suggestions about how to improve it. And then I was charged with $89 for technical evaluation, but that wasn't what I requested in the first place. The technician was courteous, and did validate everything works fine. No complains there, but he was the wrong person to be sent to my house in the first place. So, if you want to have a larger project done (it was split system installation in my case), just work with other companies, they will be much easier to communicate with and such project evaluation will be free. read more

I requested the cleaning service for our HVAC evaporator coils. Stephan Reich was incredibly friendly, helpful, and knowledgeable. Within a minute, he identified that our condensate line was blocked and quickly resolved it without any issue. He even cleaned up a few additional issues like some of the old wiring connected to the temp sensor, and a kink in condensate tube that would've repeated the same issue with our coils. Thanks again Stephan! read more

3 aspects to this service review. 1. Timeliness in reaching company to set up maintenance service appointment 2. Quality of service 3. Quality of service person 1. We got the HVAC system installed 2 years back, and it came with 2 free annual maintenance visits. I assumed that the company would keep track and reach out for the scheduled maintenance visit. Nobody did. So I called them, and after that, they were prompt in setting up an appointment. One ding for forgetting us, but one plus for setting up the visit promptly when I called. 2. Quality of service: Excellent. The work was done cleanly and professionally. All plus. 3. The Service tech, Agustin Aguirre, was excellent in all respects, from explaining the work, to keeping things clean, and going about his work properly. All plus. Would I recommend them: yes. read more

I have used Comfort Energy to keep my heating and ac system running smoothly for several years. I have had minimal operation issues since the installation years ago. Stephan is very knowledgeable, personable, and thorough in his handling of the system. I highly recommend Comfort Energy and definitely recommend you have the seasonal maintenance on your home systems. You will save $$ read more

UPDATE: changing my rating to 2 stars as the $562 diagnosis and repair service we paid for lasted us for only 2 WEEKS before having the same issue of water dripping out of the drip pan from our ceiling again. At the time, I thought it was worth paying the price to fix our problem as we were diagnosed to have a clogged condensate drain line, but now we are told that our entire AC system should be replaced. I wish we knew this earlier as I wouldn't have wanted to waste $562 for a minor temporary 2 week repair when our whole system is now recommended to be replaced. --------------------------------------- ORIGINAL: Our AC was having issues leaking rust colored liquid into our bathtub as well as making occasional gurgling sounds from our sink in that same bathroom. Apparently the drain above the bathtub is a secondary/backup drain line meaning that the main condensate drain line was clogged. Once both drains were clogged, the drip pan in our ceiling started collecting water which started pouring out water once we opened up our ceiling to access the AC unit. We were assisted by Stephan who was very professional, knowledgeable, kind and thorough in his work. He helped explain to me our issues and gave us suggestions as to how to prevent something like this from happening again so soon as this is an inevitable AC issue that has built up over the course of several years. When I booked my appointment, I would suggest calling the company number as it was faster than waiting for the automated Yelp response to my message. The time frame given to me from 8-11 am was actually the approximate arrival time. Stephan helped to diagnose our issue and fix the clog by blasting nitrogen gas into our main drain line and then our secondary drain line which was very difficult to access in our condominium unit as we have a ceiling pancake HVAC unit. It took like 2.5 hours to complete everything. Definitely recommending Comfort Energy for any AC needs and request for Stephan! read more

Huge fan of Comfort Energy here with another review. Comfort Energy installed my mini-split last year and had great experiences with all the team! Since then our neighbor went with Comfort Energy after telling her how great they are and they had the same experience. We just had our annual service and again received top tier service from Belsin (another rockstar). Some highlights from our service: - brought up a question/concern re: our condensate lines, Belsin fixed it with no hesitation! - worked around my home work station and the kids (even answering my sons questions) - respectful, wearing coverings on shoe's (which I notice all the team does at Comfort) To piggyback off my previous reviews: If you are thinking about investing in mini split (or all your HVAC needs) you won't go wrong with Comfort Energy. From Estimate - Install - Inspection - Annual Service we have received top notch service. Thank you Belsin! Your fix on our condensate lines will help keep the bugs away. read more

If you're considering HVAC services, I can't recommend Comfort Energy enough. I put off the mini-split AC installation for years, but decided that 2024 was the year I would stop sweating in my own house all summer! I was hesitant to go through the process because I was dreading the coordination with my HOA, but after my neighbors wholeheartedly recommended Comfort Energy, I decided to pull the trigger. Maurice was quick to provide everything I needed to get HOA approval and kept me informed of next steps along the way. I was absolutely delighted with the exceptional quality of work from Guillermo, our lead technician, and the level of service provided by Beto. From installation to city inspection, everything ran like clockwork. They were extremely professional, got the work done quickly, and were accommodating of my schedule, especially when I needed to take some work-from-home meetings during installation days. Don't wait like I did--reach out to them now! I could have been enjoying a much more comfortable home for years. read more

Once again - Comfort Energy to the rescue! I've used Comfort Energy a couple of times now and I'm very happy with this company. Thank you, Belsin! Thank you everyone at Comfort Energy for the honest work and prompt response. My AC water condensate line was clogged. Initially we thought a new line had to be installed. But, after Belsin's diligent troubleshooting the line was cleared and extended properly. It's perfect and saved me a huge expense! Also this, the AC stopped working on July 3rd, during the heatwave. After getting in touch with Comfort Energy on July 5th, Belsin came over on July 6th. We couldn't perform the repair right away, other contractor issue. But Belsin did not leave my family and pets without AC. He found a work around; I can't express enough gratitude! Back in January 2023: Great company! Great management! Great staff! Troubleshooting can be very difficult, and you don't always get the expected outcome. Comfort Energy went above and beyond to restore heat when needed most and fix the furnace. Thank you! read more

Comfort Energy installed a new furnace in my house. They gave me the most competitive quote among the three companies I interviewed. I can't say enough about the quality work and professionalism each of their employees showed. Maurice Samprath , project manager was very knowledgeable and patiently answered all my questions and concerns beforehand, Guillermo Tejeda did the actual installation and he did a thorough , maticulous work. I had a small concern about the furnace afterwards, Fabian Aguirre came all the way from San Jose to San Leandro and addressed all my concerns which turned out minor . He was patient and courteous throughout. Lastly, Beto Lopez handled the city inspections. He came before inspector was scheduled to do all paperwork and prepping and waited until the inspector turned up almost three hours later. (Only one inspector working that day). Working with Comfort Energy was truly a pleasure. I can't recommend them enough!! Thank you! read more

The team of Guillermo and Fabian worked very efficiently in installing our new heat pump system. Fabian answered all my questions and was very up to date on all aspects of the new system. Guillermo did a very nice job fabricating the conduit between the new pump and the main intake duct. At the start, Maurice provided a detailed quote and clear explanation of the rebate process. I'm still awaiting scheduling of required inspections, but so far we are very satisfied. read more

From the very first time meeting Mourice(sp), to the installers, to Beto, who met with the Inspectors, ALL FIRST CLASS. Not only First Class in their work, but they can talk, speak to you and converse. Explain in in terms you will understand. Again, First Class Team!!! Thank you read more

Our one of the tenants has an issue with HVAC as the airflow from the vent was very low. We called another company first and the technician pointed out the Bryant Fan coil might be an issue and as they were not Byrant authorized dealers, he recommended we call someone Byrant authorized dealer to fix the problem. We reachout to Comfort Energy as they claim to be a Byrant authorized dealer. On appointment day, a random guy dressed as technician shows up who has no knowledge about the inside unit or outside unit. He just said the unit is working as expected when myself and the tenant feel that the airflow is not as expected. He never bothered to look at the units and had trouble explaining the system. I guess they sent some random guy, who never had any experiences with HVAC. Don't trust them; they simply charge your visiting cost. read more

After another of PG&E's famous power outages, our heating no longer worked. I called Comfort Energy, and they sent Ruben Peña to diagnose the problem. He confirmed that the problem was the power module and stayed with me as I replaced it with one that I had. Ruben was pleasant, professional, and knowledgable. A solid representative of Comfort Energy.! I highly recommend Rueben and Comfort. 5 STARS. read more

Good quality of work and attention to detail. Communication was easy yet thorough. They gave me many options to choose from and I thought had fair pricing for the work that did. read more

On time installation and good service overall. Competitive pricing , help you with permit , guide you about ducting . Maintenance service also provided read more

I've been getting furnace and A/C service checks for years on my home and they are professional and courteous. They always call ahead and the tech will text you as well with his picture so you know. They also provide discounts on parts when sign up for yearly maintenance. They installed the high end iQAir filtration system and UV light system in the air ducts. This helped a lot when we were having poor air quality due to the forest fires in San Jose and further north. Today Johnathan came out for regular service check and did an excellent job. He detected one of the large capacitors for A/C unit had degraded past its value and we got it replaced. Thank you Comfort Energy ! read more
