Alex did a great job on our annual furnace and a/c servicing.    He spent a good chunk of time cleaning and ensuring that all worked well.   Unexpected extras included cleaning up debris and rubbish in the cabinet from years ago when unit was installed.    He didn't upsell or try to tell us we needed this or that fancy/expensive part to make sure our unit was working.    Just all is well and see you next year!    We felt like he was very honest and professional. read more

I'm a tenant that has been serviced twice by Monteros and their technician, Alex. The company is responsive, and local. You call and someone answers. Michelle does what she says she will. Alex is incredible - honest, trustworthy, and above all, hardworking. He stayed very late on two separate visits to get the job done for us. It really made a difference for us. read more

From start to finish, the service from Monteros was professional and efficient. Claudio quickly assessed the issue and explained each step of the process, and tradeoffs of repair options. A customer service oriented company. Highly recommend. They will be my first call next time I have any heating or AC issues. read more

I've been through too many to count Heating and Air people that just don't do the job right. I own rental properties and I'm always looking for somebody excellent. I found him today, his name is Alex and he works for Monteros Heating & Air. I have an old Empire Gas Wall Heater that quit on the a couple of nights ago. Of course it's pouring rain and cold, cold, cold. Alex was sent out the following day, diagnosed the issue immediately and went to work to replace it. In addition he was so nice to talk to while he did the work and he definitely knew what he was doing. He went above and beyond, cleaned up after he was finished and made sure the thermostat was also working. Needless to say, I will ask for Alex by name and will also recommend him on my neighborhood website. Thanks again for you Alex service. read more

These guys fixed our old millivolt wall heater. Prior to this, a couple of companies refused to work on it due to its age, and another company came out and tried, but misdiagnosed it and cost us a few hundred dollars without a fix. Once Monteros came on the scene, the heater was fixed efficiently and on the first try. Highly recommend. read more

Our AC went kapoot on the first hot day this year. We called the company from a sticker on the unit left some time in the past. They arrived and determined within 10 minutes that we needed a new system which they would gladly install for $6500. But hey, we'll throw in a Nest thermostat for your troubles. Second opinion needed! Yelp reviews for Monteros were great so we gave them a call. Alex came out and spent over an hour diagnosing the problem which even included going under the house to check wiring. Replacement contactor and one pound of charge...BAM we wchilln! Oh and we saved $6000! I was tremendously impressed with Alex's professionalism and dedication to doing the right thing. Honest, fast and low drama; I highly recommend Monteros Heating & Air for your HVAC needs. Cheers! read more

Alex from Monteros Heating is extremely skilled, thorough and professional. He is also a delightful person to have in out house. We have been using his expertise to have our heater inspected and fixed for years. Highly recommended. read more

Our A/C stopped working and I contacted Monteros to see if they could come out and diagnose the problem. They were super responsive and I got the confirmation for service right after confirming the date and time via email. What I liked was that they gave us a half hour time window. Claudio showed up on time and saw the issue right away, fixed it and refilled the freon and all for a very reasonable price! There are a bunch of a/c repair companies out there, but I am very happy that we went with Monteros. And so will you! read more

Claudio was so helpful in fixing our heater. He was on time, friendly, and so knowledgeable. I love his honesty and that he does not try to upset you on services you might not need. We have a very older heater and will eventually need it replaced. But he was able to get it in good working condition. Thank you for the amazing service! read more

Saturday morning, February 11th, our furnace stopped working, it needed a new heater motor. Called + emailed 5 places (recommended from Nextdoor & Yelp), with all information, everyone wanted to charge $75 to $179, to come out and look. I said it would be best to see if they could get the part, as we knew what we needed. Thankfully, we found Claudio Monteros, he came to our home, took the old motor, and said he would find a replacement. So he did, it was express shipped from San Diego, to SF Bay area, and when it came in earlier than expected, Claudio came to our home 4pm (instead of 11am next day) and did the installation with professionalism, and the kindest personality. This is a 50 year old furnace, from the days they were made to last, and Claudio never mentioned to get a new heater, he knew this could be fixed... Amazing... Michelle in the office is kind and helpful, and their prices are Great. Our heater works better than before, and I would give 10 Stars to this fantastic man, who went above and beyond his calling. read more

I had water leaking from my Air circulator unit and received different diagnosis including $12k by a different company who flat out told me to replace the entire system. Claudio Monteros came out to my residence, asked me some very specific questions to understand the issue, walked me through what he thought the problem was and why, and proceeded to remedy the issue. He also found that the blower speed was suboptimal and reconfigured the blower motor wiring which a previous company messed up years ago. Overall two thumbs up, and I highly value and recommend Claudio and his services. His pricing is also very reasonable. read more

AC went out. Found great reviews for Monteros. Easy to book. Alex came out on time and was very knowledgeable, nice, funny. Fixxed the problem in less than 30-40 minutes. FYI Alex I did change my filter!! read more

I have an old gas heater and Claudia Monteros was able to take care of the gas leaking issue very timely. He is very experienced and company gives me 30 days warranty! I was worried I needed to buy a new expansive heater. I definitely call Claudia back for any AC issues. read more

We are very happy with the overall job and results from Claudio and the Monteros team.  Communication was clear, fast, and professional - before, during, and after the repair.  While it wasn't completely seamless (what work ever is??), they handled the few hiccups well and we our extremely happy with the end result. We would highly recommend Monteros HVAC - thanks, guys! read more

Alex was scheduled to come out between 2:00 - 2:30. I told Michelle that I had a doctor's appt and had to leave at 3:00. We decided to update the day via text and Alex texted me in the morning that he was the technician. He texted again at 1:22 and indicated he was en route. Alex arrived about an half hour later, diagnosed the problem and we were up and running within 30 minutes! Alex was professional, easy going and a honest man; only charged me the service call for coming out. Would use Monteros in a heartbeat. Refreshing to meet honest people! read more

Above and beyond. Really exceeded expectations: 1) Squeezed me into a tight schedule on one of the first hot days of the year to fix my broken A/C. 2) Price was reasonable. 3) Discovered a real issue I didn't even know I had. Diagnosed it while there at no charge. 4) Claudio is a genuinely good guy. Really likes to help people. Highly recommended. read more

AC unit was putting out air but not cooled air. Called Monteros and they were able to send out a technician the very same day! Alex diagnosed the problem (blown capacitor) and replaced the broken part. One of his associates also came for the first few moments to determine the best approach to get on our upper roof (home has 2 roofs and the AV unit was on the higher second roof). Everyone I dealt with at Monteros was knowledgeable, personable and efficient. Price for diagnosis and repair was quite reasonable. I would call these guys again in a heartbeat. read more

This was a terrific service and got the job done so quickly and promptly, I would highly recommend Monteros for their efficiency and helpfulness. Claudio was fantastic and I will never go anywhere else now. It is the best. read more

I know some about HVAC from 20yrs working on my own direct-vent furnaces, sealed-combustion gas fireplaces, installing A/C, etc. For stuff I can't handle, I call Claudio at Monteros HVAC because he's the absolute best in the industry. Claudio is a top-notch expert, a gentleman, and most important--he's focused on excellent customer service. An old-world craftsman who values doing the right thing, every time. If you need HVAC work done, treat yourself to the very best: Monteros HVAC. Why look anywhere else? read more

Picture this. It's (California) cold (so like 50°) and your significant other is freezing. While you believe in the virtues of long sleeves, he believes in a sauna experience. So you finally crank up the heat (by 2°), hoping to surprise and delight him when he arrives home when all of a sudden you get an error message from the nest saying the RH wire is disconnected. UGH. Flash forward to the next day, I call Monteros Heating and Air and Michelle is able to send Claudio out the next day. Claudio arrives impeccably on time -- I do not (thanks last minute meetings!). He graciously waits for me until I arrive and inspects my unit. He pops open the wires. Everything fine. He checks the wires and hoses. Still great. Then he checks the switch and ... it's off. Wait, there's a switch?! He flips it back on and lo and behold, heat has returned once again. So let's recap. I'm late and this service call is just to flip a switch! He generously waives the fee and when I ask him if he'll ever come back if my AC goes out, he replies "of course, but you're now the 8am call!" This company is honest, thorough, and reliable and I definitely will call on them again if needed! read more

Claudio had installed our hvac a few years ago. Recently we had some issue with it and Claudio came in on time and did the work. Also the lady who schedules the visit is really polite and nice to talk to and seems genuinely interested in helping you. I hope more service folks show these qualities. read more

Love Claudio and crew. The best in the area.

I'm so happy to have called Monteros Heating & Air to service my AC unit. Alex was very professional and knowledgeable. He answered all of my questions about how it all works with a lot of enthusiasm. I will be calling them back in the fall to service my furnace. Hopefully Alex will be available! read more

I had a great experience with Claudio Monteros of Monteros Heating & Air. I have a floor furnace--which other HVAC outfits refused to fix. Monteros not only fixed my furnace well, but did it at a reasonable price. I'm super happy with the job and will definitely use them next time. read more

I had shopped around and found this one reasonably priced. Alex was well spoken and clear about what needed fixing with my AC. I would definitely recommend this company read more

Quick, professional, WONDERFUL service. So refreshing as this is not the norm anymore. I will recommend Monteros to every person I know. Not having working AC in the middle of summer is rough, but Monteros Heating & Air took care of the problem timely, on-time, and was professional from start to finish. Thank you, thank you, thank you Claudio and Michelle for 5-star (what felt like VIP) service. Keep up the Excellent work! read more

I highly recommend Monteros Heating & Air. My furnace started making a loud knocking noise at startup, and Claudio was able to come out to visit my house on the same business day as my initial call. He helped me to debug what was going on with my furnace, and he figured out that my newly installed thermostat was configured to control the fan instead of leaving that to the HVAC unit. The fix was simply changing this setting. He also explained why this setting was causing the noise, and I now have a better understanding how my furnace works. He also refused to accept any payment for this consultation, despite having taken the time to drive to my house at the end of his workday. Thank you Claudio and Monteros Heating and Air for helping me resolve this issue very quickly! read more

Our AC was blowing warm air after few hours of running and we needed someone to take a look. After playing phone tag with Michelle for a week, we finally were able to get Alex to diagnose our problem. He was right on time and was so very pleasant and friendly. He was able to fix the problem quickly and efficiently at a very reasonable rate!! Another company I called was asking double the amount for diagnostic call. Such a pleasure working with this company, from scheduling with Michelle to the actual service call with Alex! Highly recommend!! read more

The owner Claudio saved the day yesterday by fixing our A/C during a crazy heat wave. We have always gone with larger companies for HVAC service but Claudio got great reviews here and was able to come out next day. We will definitely seek his services for future repairs. He took the time to explain what was wrong with the unit, and answered many questions that previous service providers couldn't answer. Very reasonably priced. Total bonus - getting a specific appt time instead of a 4 hour window. Thank you Claudio! read more

I highly recommend Monteros Heating & Air. Working with Claudio and his team has been an absolute pleasure. My wife and I replaced our furnace and added a central AC unit to our ~2,000sf home. After securing quotes from 5 local HVAC companies, we went with Monteros Heating & Air. Claudio and his team gave us a thorough explanation of the work that would needed to be done, our options, and when his team would be able to start and finish the project. It's worth noting that in order to have an optimally running HVAC system, we needed to increase the bandwidth of the return air line running to our heating/AC units. Claudio pointed this out to me while other vendors did not. When his quote came in, even though he was offering to perform more work than the other vendors, it was at a competitive price that was lower than many of the other quotes. During installation, Claudio and team took great care to have a minimal impact on my family. We barely noticed the installation was happening. Everything was kept clean and they were very careful moving units into/out of the house. Most importantly, the HVAC system works incredibly well. Temperatures reached 100F the other weekend and our house was kept nice and cool. The house cools very fast too. I notice that if I forget to cool the house, I can still get temperatures down very quickly (compared to other homes my wife and I have lived in). For context, I have made extensive renovations to my home and have had to work with a wide variety of contractors / vendors over the last 2 years (roughly 15 of them over the last 3 years). I've found it almost impossible to find honest, reliable, AND reasonably priced companies to perform home improvements in the Bay Area. Monteros Heating & Air is the exception. read more

Just had a furnace repair and took the opportunity to have a WiFi thermostat installed. Alex was great!

I'm blown away by the service from this team -- Michelle and Claudio were so great. Michelle was super helpful and got us scheduled within a week (other HVAC companies either didn't call back or couldn't see us for 4 weeks). Claudio fixed the problem in less than an hour and their prices were very reasonable. Thank you Monteros! read more

After my AC failed, I called several vendors for estimates on a new one. Out of all the vendors, Claudio was the only one who said "maybe we can repair your unit. It can be something simple and it would be much cheaper than a new unit". He double-checked electrical and tried a new capacitor. Unfortunately the compressor was broken and replacing it too costly. He did not charge me for any of this work. In the end, I went with a different vendor, who offered the brand I was looking for (Night & Day). But Monteros wins the prize in honesty, good service, and trying to help the customer. read more

It took considerable time to read through all reviews of Yelp and Google to find this Diamond in the ruff. It took less than 24 hours to get back to us,and it is a Friday, and they scheduled an appointment for the next day, a Saturday,at no over time fees for a weekend. The appointment was early and Claudio was very friendly and professional. A part of heater just needed to be cleaned and we were charged a very reasonable price. This is a very honest and reliable business that we highly recommend. read more

Since we had the hood above our stove installed five years ago, it just was not extracting smoke and fumes - it seemed to be doing the opposite and almost every night our kitchen living room would smell! We were considering to replace our hood, which would have cost over $1,000. I met with 3 other HVAC companies and they just didn't seem like the right fit. Claudio came over to quote and came up with the suggestion of increasing the size of the jack on our roof because he said it was not big enough to help us save money. And he was RIGHT! Rodney and Randy came over to do the work and they were fantastic! They were so very professional and were so conscientious. They did not enter the house when they didn't need to and took the long way around the house to get to the roof each time. They would even knock on the front door out of respect, even though they had been working on the job for over an hour. They were very quick, efficient, and the work was done so well! I now understand why this company gets 5 STAR ratings! They saved me a bunch of money, did the job so professionally, and the work has really changed my family's lives. We can now cook and not even smell that something is cooking. It is truly such a blessing to have found this company. I would whole heartedly recommend them to family and friends. read more

Alex at Monteros was awesome! He showed up on time, was courteous and professional. He quickly diagnosed the problem and was immediately on the phone to get coverage from our insurance provider. Then he made quick work of the repair and we had our A/C up and running again in no time! If you're in need of HVAC repair, then Monteros is the company for you. You will not be disappointed! read more

Claudio is extremely knowledgeable about all things heating & air! I was searching Yelp for someone who could provide me with a zoning system quote. I utilized Yelp's "Get a Quote" feature and received a response within a few minutes. While Claudio provided an basic scaled quote, he indicated he needed to perform a visual inspection for an accurate quote. Since he offered a free quote, I called his office and scheduled an appointment with Michelle, who was very friendly and accommodating with my schedule. Claudio arrived on time and quickly began his assessment. He also asked me why I wanted a zoning system and offered a very insightful understanding of how the system works and expectations. Additionally, his quoted price is thus far, the best received to date. He's an ultimate professional who's very courteous and kind. I will definitely hire his company for my zoning system placement. I highly recommend you consider his company! read more

If you need AC, Monteros is the place to go. In 2 1/2 days we had 2 American Standard compressors installed. With all the duct work, this was new installation. Rodney and Randy were very professional, and pleasant workers. I highly recommend this company. read more

After the latest heatwave, our AC had an issue. I called around and was repeatedly told it would be more than a week. I can't fault companies for being busy. It is what it is. After talking with my dad he recommended Monteros based on his experience with Claudio. I received a call back the same day and had an appointment for four business days later. Alex was prompt with my appointment time and very friendly. We chatted up the issue a bit, and he dove right in. Five minutes later, the issue was diagnosed and he went to retrieve the part from his van. Super easy, impressive service from dispatch to Alex and overall impressive customer service based organization. They will be my go to for my heating and cooling needs. read more

Claudio helped me install my Nest via text message. I sent him some pics and he gave me instructions to get it up and running. I asked him to pay for his service and he just replied "it's fine". Great guy. Next time I need any services I know who to look for. Thanks Claudio!! read more
