Claudio was super nice and super helpful! Would recommend him 100 percent! The initial cost of calling him out covers future visits as well (if something goes wrong and he has to visit again). read more

We contacted Monteros Heating & Air as we needed to check if our air-conditioning unit needed to be replaced and also we want to get our air-conditioning unit moved from the side yard to the back yard. The lady who picked up the phone was very pleasant and efficient and helped schedule an appointment for Claudio to come to our house. Claudio arrived on time and we found him to be very courteous, professional and knowledgable. He gave us some excellent recommendations regarding our cooling and heating requirements. He also promptly checked our air-conditioning unit (which is relatively new) and did some basic trouble-shooting to check for cooling efficiency. He could very easily trouble-shoot the freon disconnect issues and assured us that we did not need to replace the unit. We have yet to have him come and move our air-conditioning unit and fix our heating-circulation issues, but if his 1st visit is any indication, we have no doubt he will do all the required work most professionally. Claudio is most definitely an amazing HVAC expert and a very pleasant and reliable human being. read more

I can't say enough GOOD things about Monteros Heating and Air!! They are friendly and responsive and honest -- and how great is that?! ... Our furnace stopped working, and we had two companies come take a look at it. The first company diagnosed the problem as being a faulty blower-motor, but strongly recommended purchasing a new heater altogether ($4500). In sharp contrast, Alex from Monteros did diagnose the problem as lying with the blower-motor, but he also then *fixed* the blower-motor on the spot (for the price of a service call), and emphasized that, even if the problem returned, we would only need to buy a new blower-motor (a fraction of the cost of a new heater!), and would definitely *not* need to buy an entire new heater altogether. That kind of integrity and honesty and trustworthiness in a repair company is GOLD. So if you have a heater or A/C issue, look no further, and call Monteros. Michelle is a delight on the phone, and Alex is not only a thorough, efficient, and effective technician, but he's a great guy -- and hilarious to boot. Monteros is your company, 100%. read more

My furnace was not working and my grandpa had used sears all his life so I called sears to come out and repair it. It cost $60 for him to just come out. When the sears guy got to my house he looked at the furnace (which is old) for about 10mins and told me it would be hard to fix it, but that he would have to make a call. He went to his car and made the call, only to come back to tell me it was "too old" to fix. The part that needed to be replaced was not available anymore. Not knowing anything about furnaces I just agreed. I was told I needed a new furnace and the sears guy came over to quote me on a new one. I wanted a second opinion so I called Monteros, and asked if he could come by and quote me on a new furnace as well. Appointment set he came over and I explained my problem, he was there to quote me but he spent time attempting to fix it instead of trying to get me to buy a new one. Within 1 hour he had it working again, and suggested that the part that was not working 100% could be replaced if he could find it. I agreed and he made the call, finding the part. Waited for the part to arrive and he installed it. Now I can be sure that during these cold times my heater will work. Friendly, trustworthy and reliable. read more

WOOHOO!!! We have A/C again! I can't say enough good things about Monteros and Alex (the A/C expert who came out to make the repair). Alex went to great lengths to find the problem as to why we did not have cooling. He told me from the start that he would solve this issue and he did! Alex was quick, knowledgeable, and actually quite funny. He ended up having to go into our crawl space below the house and found the problem. He made the wire repairs having to contort his body to reach the area, and did so with some humorous whining. He was awesome! If I EVER need someone again for heating or A/C repair, I know who to call. =) . Thanks again!! read more

These guys continue to be the best in the valley. Claudio came out today for a problem with an air conditioner, figured out it pretty quickly and refused to take payment. Said if the issue recurs and he needs to replace a part we can take care of at that time. Awesome, came out during the heat of the summer with only a couple days advance request. Contrast that to a different vendor that came last summer for that same unit that charged an arm and a leg, and appears to have not really fixed things since it broke less than a year later. I will call Monteros whenever I have a need. read more

Claudio runs an outstanding company, and his employees are great. We had them install a central a/c for our home, using our existing furnace adding an American Standard a/c. We really needed a quiet unit and Claudio guided us in our purchase. We were so pleased with Rodney, and Randy that we tipped them nicely at the end of the job. This company is worth waiting for! read more

Had a furnace issue and they were quick to respond and set up the appointment for the next available slot which was next day but were nice enough to follow up on a cancellation to set up for same day. Really like the quick response. read more

My 65 yr old furnace quit during the night, and it was cold in here this morning, and I have guests! I needed help right away. My go-to furnace person was fully-booked today. The other firm he suggested was booked until Friday afternoon, and didn't seem very enthusiastic about fixing my old furnace. Yelp led me to Monteros, a quick response to my phone message, an appointment by 10 am, and Alex was able to inspect, adjust, and get it working again in under 30 minutes! Great experience! read more

My heater died, during the frigid Mountain View winter... I did some basic diagnostics and decided I should call in an expert. I used Yelp's new messaging service to talk directly the business, It worked great and they responded quickly. They told me to make an appointment... A couple hours later I get a call and set up an appointment for tomorrow morning with a 30-minute window. Alex showed up on time, was friendly and diagnosed the problem quickly. He had a replacement board in his van and the whole thing took less than an hour. Well done guys! read more

On the first day of a heat wave I had the brilliant idea of switching to my nest. Well, everything went wrong and I was SOL until Claudio replied to my message and tried to help over the phone. They were able to diagnose part of my problem with no charge, but due to some miscolored wires and my not taking a picture of the original state, they needed to drop by to finish the job. They came on a Sunday on Father's Day to help with my A/C. Definitely a life saver and a very honest business. read more

I had a problem with my main air conditioner - it kept staying on even though the thermostat was off. Claudio came out and fixed it and did not charge me! He told me a part in the unit may need to be replaced but in order to not buy a part we may not need, he recommended waiting. Eventually the part did need to be replaced and Claudio came back out and took care of it for me. Claudio is super helpful and seems to really know his stuff. He is also very reasonably priced. I highly recommend Monteros Heating and Air. read more

Claudio is amazing!! It is such a pleasure to give an outstanding review for GREAT service! In addition to being a consummate professional, he is incredibly nice! THANK YOU, Claudio! Cheers, Elizabeth read more

Claudio is amazing. He goes above and beyond for his customers. Not only has Claudio been responsive, responsible, and very efficient in his service delivery, but their office admin Michelle is incredible as well. read more

I used this company twice now and two different businesses for two completely different equipment issues. Both times the technician was prompt, polite and extremely well priced. He obviously is a true professional and actually a lot of fun to chat with as well. I can't stress enough how much I recommend monteros for any HVAC needs. read more

Our experience with them was wonderful. Claudio was friendly, professional and on time. We would highly recommend them. It was the hottest weekend ever and he was really busy but he made the time to come out and get our air conditioning up and running again. Reasonably priced too! Great experience. read more

I can definitely recommend Monteros Heating & Air. They were right on time for the appointment, fixed the main issue, made some improvements, gave me some useful advice. read more

This is a follow-up to my review about two weeks ago. Claudio ordered the part for me, kept in touch with updates on its arrival and finished the job last week. My A/C works perfectly now. Claudio is a great guy, highly recommend This company! read more

Our AC was working sometimes and sometimes not. Claudio came out and of course it all worked perfectly while he was here, but he still found the problem and fixed it. All has been fine since. Claudio was very friendly and professional and explained everything very well. I will call Monteros again if I need HVAC help. read more

Do your homework before any repairs are made. In January our furnace stopped working. I used the yelp rating to choose Monteros. Claudio was on time, explained the problem, tried to fix the part before finding that it needed to be replaced. So far, so good. When it was determined that the part on our furnace needed to be replaced, he said that the inducer motor assembly was an expensive part. I took his word for it and gave him the okay to order the part and complete the repair. Although at the time I thought that the quoted price for the part was a bit high. He obtained the motor assembly and was back the next day to complete the repair, which took all of 10 minutes. The furnace began working again and has continued to work. After he made the repair we chatted for about an hour. Since then I have been doing a good amount of work on my house, including the purchase of several power tools. I have a pretty decent idea of how much things cost. Today when I was filing old bills I ran across the invoice for this job. That high cost of the part, $393.00, was still nagging at me. So, I decided to look online for the part. I plugged in the part name and number and low and behold it is available on several different HVAC supply sites for $168.00. The three stars are for his knowledge, timeliness. The missing two stars is for once again being taken advantage of by companies because of the zip code in which I live. Again, I'd recommend his work, but before you have any parts replaced, check online for the real cost of the parts and negotiate accordingly. read more

Courteous, prompt and reasonably priced service. Claudio was able to give me an appointment for the same afternoon I called. He checked out our old furnace that wasn't working because the pilot light had gone off. He replaced the thermocouple and ensured it was working right. Also, reassured me that even though it was a very old furnace - now with summer coming should work fine for some time:) read more

If someone is available over the holidays to come and take a look at something wrong in your house, they are already batting a thousand. The heater in our house suddenly broke on Christmas Eve. Oh and if that wasn't enough, we had houseguests, that had two small babies... basically a situation from hell... Well I looked on Yelp and found Monteros, which had a five star rating and called them. Claudio came immediately and told us that the motor died and we would have to replace it. He said that it wouldn't come until next week but he rerouted one of the pipes so that we would temporarily get sporadic heat until he came back. We would we happy with his services at that moment itself. When he came back to finish the job, he was fast efficient and we now have heat in our house. The cost was also not half-bad but for coming in over the holidays, I would have paid double. Thank you Claudio and Monteros Heating & Air! read more

Alex checked out my furnace for maintenance. He was completely professional as well as friendly and informative and helpful. Thanks so much for such an excellent job! read more

I highly recommend Monteros Heating and Air. Claudio had worked previously for a company I had used. He then started his own business. I highly recommend Claudio and his team. They are thorough, honest, friendly, and reasonably priced. I was so happy to find him again to service my furnace. He is one of the best out there trying to help customers like you and me. He deserves more than 5 Stars. read more

Very prompt, diagnosed the issue right away and reasonably priced. They were able to give me an appointment the next day and this was in the middle of a heatwave. Alex was very nice and even gave me a crash course in air conditioning 101. Would definitely recommend this company over all others. read more

Claudio is awesome! We are new home owners, and returned to our home after being abroad for a few weeks, to find that our central heat was not working -- all this in the peak of the winter. Another HVAC company told us we'd have to replace the entire unit costing around $4k -- I called Monteros for a second opinion -- Claudio examined the issue and tried to come up with much more cost effective and sensible solutions than replacing the entire unit. This meant he'd have to spend time really digging into the cause of the issue and he did that! In the end his goal was to set us up with a short term fix, until he could come back, investigate further and figure out a plan of action. So in a market, where most of the people are too busy to even call back, much less pay a visit at their earliest convenience -- interacting with Claudio who showed up, thought strategically about how to get us back on our feet by showing care and concern for us having a solution, until his schedule allowed him to come fix the bigger issue -- was like a breath of fresh air. He stayed in touch with me through prompt texts, and the heater is also mysteriously working fine w/o the more complicated fixes. He was incredibly pleasant to interact with the entire time -- and just got the sense that he's a very kind person. read more

We needed to replace a noisy bathroom exhaust fan but the tricky ductwork proved too challenging for this DIYer. Claudio took it on and solved our problem. Good guy! read more

Alex is the best. He was on time, super knowledgable, and very professional. He diagnosed the problem quickly, replaced the part...and before long, my AC was working again. Alex also reminded me about the importance of periodic filter changing! I'll definitely call Monteros the next time I need any work done on my HVAC system. Thanks again. read more

Great service and reasonable price. The first time the tech changed the parts but the furnace didn't work as planned. The boss came by the 2nd day and spent 30 minutes to figure out the problem. read more

Claudio was great. I rarely write reviews, but he earned it. He texted when he was on his way, arrived on time, knew what he was doing, and got the job done efficiently and at a reasonable price. I've had enough experience with companies that do heating and AC to realize that it'd be hard to find a better person than Claudio. If you're searching around, don't search anymore. Definitely hire these guys. read more

Claudio came to my house with other two team members for two wall heaters installation. They finished job within 3 hours with professional skills. The price is very reasonable. I really high recommend them. read more

Very professional. They needed two visits to repair: one to diagnose. 2nd visit after new compressor shipment arrived for install, welding, and test. Both visits were done correctly, on time, explained carefully what was wrong, and what would happen next. I like that they are very good at communicating electronically if you like that: they confirm appt beforehand using text and email. Then tell you they are on their way to your house with text/email. Then a summary after visit with text/email. And receipt via text/email. You get the idea; I like this extra communication. read more

Arrived early and fixed the heating problem quickly. The only issue is that they charge a lower service fee but as another reviewer said they inflate the price of the parts ($64 for a $20 max part). Took one star off for that. Otherwise, I would have been quite happy with the experience. read more

I'm very happy with the service. The technician came on time and fixed the problem promptly. It was much cheaper and easier than I had thought. Payment was easy as well. I will use Monteros again. read more

This is my 2nd review for this company, again 5 stars (I would give 6 if I could). This time I had my AC failing on a very hot (103F) Sunday 06/18/2017. I left a message for Claudio, but his office is closed on Sundays. Having a sick person at home for whom the heat was a big problem, I called another company, which worked on Sundays and happened to have good Yelp reviews. A technician came in, then another joined him, they spent at least 5 hours, replaced contact box and capacitors, and still the unit was not working. Then they suggested a total replacement of the AC and the furnace coil, $4500 total. Yeah, right. Monday morning I got a call from Claudio, he had his schedule full for the day, but I mentioned that I have a sick person at home, and he agreed to stop by. He came and fixed the whole thing in 15 minutes, while finding that the other guys almost burnt my fan motor by shorting it with an incorrect capacitor. And Claudio's labor and parts fees were on very reasonable side. Need I say more ? read more

Called on Monteros to service my central AC, which was barely putting out any cold air, and was able to get early appointment the next day. Their tech Alex arrived on time, got to work and before long got my system running well again. Great service, and the fee was very reasonable. Would call on them again, highly recommended. read more

Monteros Heating and Air is our new go-to service for furnace repairs. We had previously used another long-established service in the area but gave up on them after a bad experience so we gave this team a call. It was easy to make a convenient appointment, our technician Alex showed up right on time and quickly fixed the problem -- which turned out to be a faulty thermostat. He also serviced our furnace, cleaned the ignitor, and explained how to properly maintain the system all for a very reasonable fee, with everything fixed on his initial visit (unlike a competing service, which charged us money to look at a problem even though they did nothing to fix it). Alex even showed us how to program our new thermostat. Monteros Heating and Air will always be the first call we make if we run into any additional problems with our HVAC system. Thanks, Monteros! read more

Claudio and the guys are amazing. We just installed a central A/C unit for our house. Pricing: great. I got 3-4 quotes and his was best. Quality: top notch. Excellent work. Works and looks nice. Speed: first person to give quote, did job in two days. Personality: really nice, earnest, friendly. No bogus upsells. What else do you want? Good deal, good stuff, nice people, honest. Very happy. read more

I had a great experience with Monteros. Alex arrived right on time. He was very knowledgeable and communicated very well. As it happened he did not have the particular part for our heater in the van. However, he was kind enough to drive to San Jose to pick up the part and bring it back on the same day to get our heater going on the same day. My family is very grateful that we didn't have to spend another cold night. The cost was also very reasonable and there was no sales pitch. I recommend Monteros to anyone in need of furnace repair and particularly Alex with his technical and diagnostic skills. read more

Alex came by to fix an issue with my AC unit. He was on time, and did quick but thorough work. Highly recommended!
