"Absolutely outstanding service. My AC was not cooling properly and making noise, and Max is diagnosed and fixed the issue quickly and professionally. He explained everything clearly, arrived on time, and made sure the system was running perfectly before leaving. The air is blowing cold again and the unit sounds much better now. Very respectful, knowledgeable, and honest work. I highly recommend this company to anyone needing HVAC repair or AC service." read more

Super happy with the work from Lorenzo heating and cooling. I originally called when my furnace stopped working. My furnace along with my AC unit were roughly 30 years old. I knew they were getting close to needing a replacement as my AC unit went out about 3 years ago but was fixable. I reached out to this company via Yelp and they got back to me very quickly and had upfront pricing for coming to diagnose my issue. A reasonable fee of $69 when the next closest was over $100. Anyway, Max arrived promptly and was very professional and courteous. I could tell he wasn't trying to sell me anything as he explained that some of these old heating units are better to fix and keep because they just aren't made like they use to be. He was transparent and told me that he could fix it but there was no guarantee how long it would last. He did not suggest i get a new unit, but I inquired as to the cost to just upgrade my HVAC system to become efficient and effective. Max provided a full quote within about 24 hours of servicing my unit. He explained the breakdown cost of two different systems and didn't try to sell me on a more expensive one. Anyway, we scheduled the replacements and they did a great job. Each unit took about 4 hours to complete and they had to do in two sessions since we were dealing with some heavy rain on the first session. They left my house very clean, were super cool with my barking dogs and were just all around nice guys. The price was also very competitive and reasonable. Nothing beats having a comfortable home. I'd highly recommend LORENZO heating and cooling. read more

Max is the best. He is very knowledgeable about radiant heat systems, even old ones like mine. He is friendly, easy to talk to and ask questions. And, he explains everything. He is on time and he even made time and squeezed me in when I called because the weather had turned cold and I didn't have heat or hot water. He came that day! And, back to being on time, his office and he send texts to confirm appointments, which I think is very workable and professional. His office, Cynthia, is, also, very friendly, and helpful and cares! I, really, can't think of a better run office, business! read more

We had a problem with our water heater. Our pilot light wouldn't stay lit. We got 3 quotes and Lorenzo heating was quick to respond and very knowledgeable. He did not overcharge us unlike a major company that quoted us over $500. Max was thorough, explained everything to us, and was very nice. We will hire him in the future when we replace our heater. read more

I would highly recommend calling this company if you having HVAC problems. They came quickly. Showed up in the time window they promised. Sent a text ahead of time that they were on the way. Max was polite, patient, thorough, and had great advice. He fixed our furnace but also explained alot about how our furnace works, how to read the error codes and what to expect from our furnace in the future. Like other reviews have stated, in our case as well, we felt the bill was fair and not overpriced at all. read more

First, I did not get any compensation from posting. If there is more that 5 stars, they definitely deserve it! For reference, my Bryant AC's fan is not working and was making this loud hissing sound! I was tormented w the summer heat plus the fact that I worry my AC unit might blow up at anytime. So I contacted this company and they were very responsive! They gave me a sched in a short amount of time. The actual day came. Max came to my property promptly. He checked my AC and knew right away what was wrong. He also checked my furnace and changed the filter! He also recommended ways to maintain my AC. He finished in less than an hour. The price is also reasonable. Overall, I am highly satisfied with their service. Plus the fact that they are our neighborhood company. I will definitely use them again in the future. Highly recommended! read more

Max came to fix my water heater, he was so kind , courteous and knowledgeable, and very responsible to solve the rare problem of my water heater. read more

Max has been a huge help for our home's HVAC needs. After moving into a new home, we were unfamiliar with the HVAC setup and wanted to install exhaust fans in our bathrooms. Max diagnosed the issues with our old bathroom fans (they were centrally powered by a single weak attic fan) and helped replace our bathroom lights with a fan-and-light combo unit so we could reuse the lights' electrical wiring. Max allowed us to pick our preferred fan models (e.g. the kind we wanted from Panasonic), and had a very competitive price for the installation. Most recently, we needed a tune-up of our heat pump and condenser unit, as well as repairs to install a hard start compressor kit (to prolong our condenser's life), water leak detection for our air handler, and general cleaning of the condenser's grime and dirt. Max performed all of these repairs professionally without issues, at a price that was hard to beat. We are very happy with our new exhaust fans and repaired HVAC system, and will continue to use LORENZO Heating & Cooling for our future HVAC needs. read more

See all

Great job, great value. The guys they sent to replace my hot water heater were fabulous.

Making an appointment was quick and easy. Max was showed up promptly, was courteous & knowledgeable and fixed my problem. Thanks!

I ultimately did not choose Lorenzo Heating and Cooling for my project however I would recommend them as I felt they are professional and provided a competitive bid. I will consider their services on future projects. read more

I called Lorenzo H&C late Friday afternoon. Max (owner) booked me for an early appt the next morning! Max was efficient, friendly and knowledgeable! He diagnosed minor issue with my furnace. Didn't require any repair. He was honest and didn't charge me a diagnostic fee. He was very open to sharing some of his knowledge/tips for things to look for and safety features of my furnace. I will DEFINITELY call him again if needed. HIGHLY RECOMMEND HIM and his company! read more

Hidden Gem! Quick, Honest, Knowledgable! This business is a hidden gem and I hope they get more clients! I called them after my last Yelp contact no showed their promised appointment. Cindy took my call & was very nice & pleasant to talk to. I needed my AC fixed asap as I had out of town relatives coming in. I asked Cindy if there was any way if I could have someone come out today. Cindy said they were booked but could squeeze me in at the end of the day. Very fortunate to get the appointment same day. I asked Cindy if she could send me proof of appointment since my last Yelp person no showed and she was happy to do it. They ended up coming an hour early. Max came and introduced himself & asked to come in. I told him in detail what the issue was and Max really took the time to listen to all the details & looked like he really got an idea on what the issue could possibly be. Max took a look at our AC Unit, the thermostat panel, everything. Max talked me thru everything he was doing as he was doing it, it was like watching a home improvement show. Max asked to turn the AC unit on & he said he could hear the possible issue , he believed the Capacitor wasn't running as good as it should. He did some tests on the Capacitor and was able to show me stats on how low it was running at compared to what the norm should be. Max quoted me a price & never pressured me into anything. I said let's do it. Max got to work. He finished everything & did the test again to show me the huge difference in stats. Max cleaned up everything. Overall, everything took about 30-40 minutes, really fast & very impressed with everything. Max, Cindy, & Lorenzo Heating & Cooling made everything such a pleasant experience & definetly made up for the no show from the previous Yelp contact I had. Have some more things planned for my AC unit so definetly will be reaching out to Lorenzo H&M after my relatives leave & this business will def be my go to place involving anything Heating & Cooling moving forward. Thanks everyone! read more

Max was here on time, and, in a matter of 15 minutes, he was able to diagnose the problem and then fix it in the next 10 minutes. Highly recommend! read more

The service was great. Fixed our water heater. Were reasonable and knowledgeable. Really appreciate them.

My AC air intake was making a lot of noise. When I called Lorenzo Heating & Cooling, Cindy was extremely responsive and polite. She managed to re-route Max while he was in-between 2 jobs to come take a look on the same day. Max arrived on time and was extremely courteous, knowledgeble, and a thorough professional. He focused more on solving my problem rather than selling me additional repair work that I probably didn't need. I highly recommend Max if you need a knowledgeable HVAC repair person. read more

Very reasonable and flexible. Prompt and excellent Service. . They will install air conditioner that is bought by the customer, unlike multiple ac and heating service which will not install if the whole system bougth thru them . I highly recommend this company . They deserve a diamond star . read more

Max Lorenzo was so fast and responsive. He is one of the best heating and cooling technician that I have ever met and had the opportunity to work with. He fixed the split unit in my ADU, which the contractor who installed it had no idea how to make it work. Max has a magic touch and it works immediately. He is knowledgeable and took time to explain to me via text on how the unit works. Man, I'm lucky to find him. He's gonna be my go to guy for heating n cooling solutions. read more

I talked to a few companies over Yelp messaging and over phone to set up an appointment and potentially receive a quote. Some were way overbooked, some were quoting way too high from the get-go, and others were simply giving the vibe of this being just another job and they just want to simply get done with it and move on. However, after talking to Max I got the impression immediately that this person is efficient, friendly and honest. We were able to get our A/C fixed and now thanks to Max we're enjoying our nice pleasant temperature at home during the summer! Side note: We were short on refrigerant and also had a leak issue. Max was able to explain the situation clearly and fix it with confidence. read more

I called Max at Lorenzo H&C to get a price to remove and install a new Air Conditioning unit, they gave me a great quote. I approved the quote. Max ordered the equipment, set out a very knowledgeable friendly crew. If you need any heating or air conditioning needs I suggest you contact Lorenzo H&C. Great Job Max read more

We are so thankful Max was out to check on our heater with short notice. We had actually been with this issue for more than a year and I would've called him SO much sooner had I realized how efficiently he was able to help. He checked the unit in the attic and noticed the insulation had fell and would've made the system overheat and shut down. That didn't quite do the trick so then he checked the filter and changed it and checked and properly set our console to use the furnace vs a heat pump, and then finally cleared another sensor of sorts with the unit in the attic again. And he did this all in an hour under the diagnostic fee. He also mentioned that our system was a little more finicky so if we had any issues he'd be willing to come out again under the same charge. Would definitely recommend and would definitely call again!! Thanks again Max!! read more

Max is professional, prompt and exceptional with his work. Fixed my heating problems with little issue. Would call on him again in the future read more

Absolutely highly recommend. Max and his crew installed a new furnace. Before installation, I asked many questions, and very very timely and thoughtfully answered. Written quote , which was adhered to. Superb workmanship! And, based on my very positive experience, recommended Max Lorenzo to my good friends, and they also had a great overall experience. He installed both a furnace and air conditioning unit for them. Again, great price, and supern workmanship. So yes, highly recommend! read more

Max was great. He arrived on time, was friendly, and didn't try to upcharge me on everything. Their pricing was very fair, and I've already scheduled annual servicing of my A/C units because of his help. I'd definitely hire Lorenzo H&C again. read more

Max Lorenzo came an hour after I called to restart my old heater and give me an estimate on a new one my previous heater company owner told me I needed. He showed me how to easily restart it on my own and informed me that the heater was in fine condition. I did not need a new one after all! He also checked out my second, much older heater and cleared it. He was prompt, pleasant, efficient, and reasonably priced. I'm pleased to highly recommend my new heating company. read more

He was great! I really appreciated working with him. Fast and economical. Did the initial service and more!

The office made an appointment to assess my heat pump water heater project and then called after the start of the window for the appointment to tell me the company does not service my area, even though I provided my address when making the appointment. The technician was apologetic, but I set aside the morning and didn't book other providers for appointments because I'd made one with Lorenzo. read more

Max came out within a day when others were going to be weeks to fix our AC during the hot weeks of early August. He diagnosed the problem (compressor not turning on) within minutes and had it replaced in another 20 minutes. He walked me through what to expect from a warranty perspective since the AC unit was only a few years old. The only thing I am still waiting on is his response on getting the part covered by warranty and then my money refunded at that time. Once that is complete I will adjust the rating to 5 stars. read more

Great service.. very knowledgeable.. will use them again.. they knew how repair and service my mini split system.

Max was very helpful. He was punctual, knowledgeable, friendly, and thorough. The service was reasonably priced.

I really appreciate what Max has done for me today. I just need some words to tell you all about Max who just came out this morning to check my water heater issue. He is very friendly, knowledgeable, enthusiastic and honestly. He will let you know what you need and what you don't need to do if you have water heater issue. So, don't waste your time to search around. Let contact Lorenzo Heating and Cooling and Max will help you. read more

Max was punctual, friendly, honest and knowledgeable. He quickly found the real problem. I talked to several companies over the phone and in-person. I highly recommend this company and will definitely use them again. read more

We had a leak in our water heater. I contacted Lorenzo heating and cooling through Angie's list.com Max Lorenzo responded within minutes. He came out to our house from San Jose to the Santa Cruz mountains and gave us a free estimate. Our water heater was beyond its years and needed replacing. We received a text the evening of the estimate asking if we agreed to the terms. This was a Thursday. We did. He followed up the next day saying he could come the following week to put a new water heater. The process of getting the new water heater was fast. He was very courteous and efficient. Max made sure we had everything we needed for the water heater, new water lines and a water shut off that we didn't have before. He taught us how to turn it off in an emergency or if we went on vacation. It also came with a one year service warranty, call anytime. He cleaned up after himself and made sure we were happy with it before he left. I would recommend 100%. He did a great job. Max is a nice person on top of everything else which made it even better. Call them. You won't be disappointed. Dana and Joseph Velasquez read more
