Rendon Heating & Air Let me start by saying, we are 100% satisfied with the quality of the work, the friendliness of the owner & staff and the quickness the work was able to be completed.The owner David was able to come out, assess the issue with our AC unit and furnace, quickly get us a quote (that was more than reasonable) and get the new unit installed within 2 days. Incredible. Julian & Brendan, their technicians were knowledgeable and really gracious and friendly. I wouldn't hesitate to recommend them and would absolutely use them again if the need arises. read more

As much as I'd love to support a local business, I would suggest everyone stay away from this company. Let me start by sharing our experience. We bought a new home sometime around October 2025 and have a homeowner warranty. When we had an issue with our heater, we contacted the warranty company, and they sent Rendon Heating & Air to our home. Rendon assessed the unit and told us it could not be repaired and needed to be replaced, which our home warranty covered. Rendon came back and installed the new unit. While it seemed like it was working at first, it clearly was not. We were told everything was working properly, and since we are obviously not the subject matter experts, we trusted them. However, we continued to have a strong feeling that something was wrong with the heater. This is a gas heater, and every time we turned it on, instead of starting normally, there was a loud **PUFF** sound that literally sounded like the gas was about to explode. On top of that, it would take forever for the heat to come through, sometimes running for 20 minutes without properly heating the house, and we could smell gas. We contacted the warranty company again, explained the issue, and they sent Rendon back out. We explained everything to the technician. Their answer? The unit was working fine and the PUFF sound was "normal" when the heater starts. Ummm... okay. So we asked, is it also normal for the heater to run for 20 minutes without properly heating the house while we can smell gas? Their quick answer was that we needed to replace the entire unit with **their machine** and move away from the manufacturer's machine. Keep in mind, this was a NEW unit that THEY had just installed. Months passed, and we still had no real resolution. At that point, we decided to bypass the warranty company completely because we did not want them sending Rendon back to our house again. We paid out of pocket and contacted two other heating companies for independent assessments because we wanted multiple second opinions. Sure enough, both companies raised concerns. We were told that the gas line/pipe could be malfunctioning or improperly installed because a gas heater should NOT start with that type of PUFF sound. They also identified concerns with the air and gas flow and told us the installation could create a serious safety hazard. Based on what we were told, we decided to have the gas shut off and not use the heater until the issue is properly resolved. This is the part that makes me angry. We repeatedly told Rendon what was happening, including the puffing sound, lack of heat, and smell of gas, yet we were told everything was "normal." Instead of taking our concerns seriously and thoroughly investigating the problem, their solution was to tell us to replace a practically new unit with another unit from them. And the customer service experience did not make things any better. The lady I spoke with constantly talked over me, would not let me finish explaining the situation, and repeatedly questioned our concerns. She even questioned why we had waited this long to check the heater and why we weren't using it. OMG... why would I turn on the damn heater when it was 80+ degrees outside? And when we did turn it on to test it, we repeatedly reported the same problem and were repeatedly told there was nothing wrong with the unit. The entire experience has been absolutely ridiculous. More importantly, when a customer reports a potential gas issue, it should be taken seriously. We trusted Rendon because they were supposed to be the professionals. After this experience, I personally would not trust them to work on our home again. read more

Not good. Just bought a house with an HVAC unit that was newly installed in Jan 2024. Worked great for the first year but went out right ,before my tenant moved out. Called Rendon to repair the unit first the transformer failed (which should have been covered under the factory warranty) paid him to replace that which now I realize I shouldn't of because that part is covered under warranty. After he replaces that he says the motherboard is out and needs to be replaced and it should be covered under warranty. He sends me an estimate of $850 and I ask is that including the part and they say yes, but we will reimburse you when the manufactured does. A TOTAL LIE! They refuse to disclose the part cost so I tell them never mind I'll find a reputable contractor to do the work HONESTLY. BYE! read more

Beware this company! They dont clear charge you before the service! We had a very disappointing experience with this company. Their technician came to our home to look at our heater. He did not provide any upfront pricing, nor did he tell us that there would be a fee before touching the unit. After doing a quick, simple adjustment, he charged us $125 without any prior notice. The heater only worked for a one time and then failed again the same day. When we called the company, the owner told us that our heater is "over 20 years old and cannot be repaired." If the unit was truly too old to repair, their technician should NOT have started any repair or charged us in the first place. This is misleading and unprofessional. We feel that this company did not follow proper business practices: * No upfront pricing * Performed unnecessary work * Charged without consent * Refused responsibility afterwards read more

Rendon Heating & Air - The conversation with David about the heater after they repaired only running short time! - Heating & Air Conditioning/HVAC Near Me - Vacaville, California

My thermostat suddenly decide not to work last Monday, Rendon was able to come out next morning for the repair, Chris was professional and knowledgeable; unfortunately after the repair, another part failed later that day, but they come out again the very next day to repair. After two repair, unfortunately, the issue was that my system was just too old and needs to be replaced. They gave me a quote within a few hours (totally reasonable after received competition quote). Accept the quote on Thursday afternoon before 7/4 long weekend, and David was able to help me getting schedule first thing Monday morning!!! The installation team is professional, efficient, and friendly. Highly recommend!!! read more

Rendon Heating & Air - AC unit/Heat pump system - Heating & Air Conditioning/HVAC Near Me - Vacaville, California

Fast to show up, faster to overcharge -- beware of Rendon Heating and Air. Called Rendon Heating and Air for our rental property's A/C with temps expected in the 100s. They scheduled quickly, which I appreciated. We were told the service call was $75 and would be applied to the repair. When billed, we were charged $89--the owner later said it was supposed to be $72. Prices seemed inconsistent from the start. The tech diagnosed a failed capacitor and contactor. He said the 2001 unit might need a $14,000 replacement but could be repaired for $750--possibly just a temporary fix. He had the parts on his truck and said it would take 30 minutes. I called the owner to confirm, and instead of addressing the price concern, he boasted he could do it in 10 minutes. The parts cost $50-$100, so at that rate, the labor came out to $1,300-$3,900 per hour. The owner justified the price by listing his trucks, advertising budget, and operating costs. I understand running a business isn't free, but that doesn't excuse gouging. My mechanic provides itemized estimates for parts and labor--this company didn't. In the end, I declined the work. They were quick to respond, but the pricing lacked transparency, the charges were inconsistent, and the focus felt more on making the sale than treating the customer fairly. read more

I called Rendon Heating and Air because my small Williams wall heater stopped working. I found their ad on Yelp and chose this company because their ad displayed a "Zero Service Call Fee." At the time of the appointment, Allante showed up, spent 10 minutes looking at my heater and told me it couldn't be fixed and the replacement heater would be around $2800. I said "No thank you" because It seemed like he didn't spend enough time inspecting my heater before he said it couldn't be fixed and gave me a pricey replacement estimate. So, Allante left. But a few minutes later, he came back and said that the office asked for $125 service call fee and that he couldn't leave until he got paid. That's called "Bait and Switch" folks and its illegal! But there he was, staring me down, waiting for payment, so I wrote him a check. Then, when he left, I called the company and spoke to Maria and told her that the ad on Yelp said "Zero Service Call Fee" so why am I being charged for the service call now? She said "Well Yelp is kinda confusing. The fee was for the work that Allante did on my heater." What?! I explained that there was no work done on my heater and I wanted my $125 back. Maria assured me that she would not cash my check and instead, she would mail it back to me. I agreed. Then, the next day, I checked my bank account and guess what? The check was cashed! So I called Maria and she said someone else deposited the check by mistake. By the end of the day, I got my $125 back via a Zelle payment from Rendon. I called another company called Creative Comfort Systems. They came and looked at my heater and fixed it for $164! I won't be calling Rendon again and I do not recommend them! read more

Chris came by my house today and fixed my ac. He went over and above showing me how to adjust the vents, educating me about the difference between the register temperature and the output temperature. He changed my capacitor and recharged my system in less than an hour! My schedule was busy and Chris worked with me and found a time to save my ac. Thank you so much to Chris a d Rendon Heating & air. Definitely recommend! read more

Extremely disappointed with my recent experience with Rendon air. I had scheduled an appt with them & they sent over their service technician Justin. Justin quickly "found" the reason our a/c was not working and I was told that they "just needed to buy the part & they would have cold air blowing for me that day." So I paid the diagnostic fee of $125 & then paid $750 for them to repair the part. Well that DID NOT fix the issue. When Justin left my house it was 73 degrees inside & we set it to 70 degrees...It did not lower one degree by the time he left to the evening. It actually went up to 77 degrees. I was calling/texting because Justin told me if it's not working to give a call & they will come look at it. Then the owner David I believe was his name, called me & was being extremely rude to me over the phone because I was not willing to pay yet another diagnostic fee because I was told it would be fixed. Then he rudely proceeds to tell me "we technically don't work on systems older than 20 years old to begin with" this was NEVER told to me. After I kept telling him how it's rubbing me the wrong way that I was told it was fixed after spending $750 & now you want to charge me again to see what may be the issue now- He told me "fine Zane I will send someone out there for free since you want us to work for free just for them to tell you you need a new system." It was truly disgusting how he spoke to me but it's even more disgusting that I was told I will have "cold air blowing that day" and that was not the case at all. That $750 could have went to a new system but no, it was wasted money & now I am getting a new system through someone else because I refuse to give anymore service to someone who scams you out your money, poor communication & down right disrespectful to their customers. For someone who "doesn't work on systems 20 years or older" was sure quick to take my $750 knowing it wasn't going to fix the issue. I do not recommend this place. read more

Got five quotes from other places to install central heating and air and they were the cheapest. Came on time and were very professional. Got things done quickly. I'm very happy! read more

Sent a service request with my home warranty. Total rip off. They said they don't make the part anymore which was a lie. Called the home warranty company to have someone come out again because my heater only worked for a day. The home warranty company told me that in the request it states that they ordered a new parts and came back the next day and fixed everything which was also a complete lie!!! Thank goodness that fire and ice heating and air came out and fixed what rendon didn't. If your home warranty company sends rendon, do yourself a favor send them back and request fire and ice heating and air. For the record no I do not own or have any ties to the company. Just a very upset homeowner that was lied to and found out the truth. read more

Rendon Heating & Air - You guys are saying you have no record of servicing my home???? That's crazy!!!!!! - Heating & Air Conditioning/HVAC Near Me - Vacaville, California

Ok it was a hot day and needed fast help...We called Rendon AC for a home in downtown Vacaville. The owner David answered promptly and provided over the phone solutions for our Mini Split unit! Super helpful and friendly to start. Air conditioning Technician was then sent out, and was on time and professional. Chris from Rendon AC then helped our tenant and spent quality extra time explaining the system and how to best use it. This was great 5 star service and beyond. They were On time, fixed the issues quickly, and communicated well.. definitely will call back Service tech Chris and David again for our AC needs. Thanks guys for great service! Price was definitely fair and especially for a quick response- read more

We just bought a house in the Vacaville area. Chris was timely and efficiently cleaned our dryer duct. Chris went above and beyond and taped up a part of our HVAC system that showed up on our inspection report for free! He also educated me on more ins and outs of other HVAC related parts of our home and related maintenance. Family and locally owned! read more

Rendon Heating & Air was dispatched to my home to perform an annual furnace tune up through Fidelity National Home Warranty. I received timely communication and responses from them prior to the appointment confirming date and time as well as the name of the Tech who would be servicing the system. Anthony came within the window of time provided. He was extremely professional, courteous, and knowledgeable. He answered all the questions that I had and was able to take care of the issue efficiently and effectively. I'm on the fence about renewing my home warranty but I'm glad they were able to send me a company that I can refer to on my own that is reliable and great to work with. I just wish I had called them during my AC tune up window via my home warranty earlier in the year! read more

Chris was amazing !!!! He helped me get my A/C back up and running. He was super helpful and understanding I didn't feel like he was just trying to get one over me. He took his time and did everything he could to get it to work. I'm so grateful and appreciative for Chris. The whole Rendon Heating family thank you read more

Dave Rendon was fantastic. He introduced me to heat pump style of heating and air. If you're looking for an honest , someone with integrity, I would certainly recommend Rendon Heating & Air. The heat pump I purchased far outperforms my old HVAC system. The filter system has reduced dust and dirt dramatically. Great job Dave read more

Our furnace stopped working this past Saturday. I immediately contacted two companies in which one never returned my phone call. David did so and I conveyed the situation to him. On Monday he came out promptly and diagnosed the problem. David then ordered the new part and installed it this morning. It's difficult to find reliable non-price gouging services. Well, if you're in the market or need for such services this is the business you want to provide such. David is quite personal, listens diagnoses the issue(s) with NO up sales! This is truly a 5 Star Business! My, wife and I will continue to use if needed and differently refer family and friends. Regards Bruce read more

Mom has cancer and just left the hospital and the AC stopped. We called Monday night and they were here the next day! Chris was very polite and quickly diagnosed and fixed the problem. I would highly recommend their service. read more

We have maintenance insurance through Fidelity. They dispatched Rendon Heating and Air to fix our heater. It needed a new panel on the HVAC unit! Anthony came out and replaced the panel. He is a very nice and professional. He was great and now we have heat, just in time for the cold weather!! We recommend this company! read more

David is amazing! Please refer to my review for reo mechanical for part 1. I went through home warranty to get my hvac fixed back in November. They sent our REO (which I believe is a scam and they really don't know what they're doing there) and it was a hellish experience, for both me and my warranty company. But after 5 months of no responses, the warranty company finally caught on and sent out Rendon! I could cry. They were helpful, and quick, and best of all, responsive lol. Thank you so much for doing your jobs so well and making me feel valued as a customer! I will definitely be recommending them to all my family and friends and only using them for any future AC/Heating needs. Fixed our system just in time for Sac's infamous summers. :) read more

I did not use his HVAC services however this man single handedly saved Halloween. My son's costume was an inflatable dinosaur that ran out of batteries as we reached Rendons doorstep. He saw that my son's costume was deflated along with his spirits and said not to worry that he had batteries to spare. He ran into his house and to his shop truck to retrieve a screwdriver and batteries all the while still handing out candy to the trick or treaters. The man went above and beyond and it speaks volumes to his character. I'm sure that if you do find the need for HVAC services, your experience will be as genuine as mine. It's rare to find people who actually care anymore, and those people take that quality into whatever they do. Thank you again, my son had a blast and I wish you a blessed life. read more

These guys are terrific!! Professional and competent! Very responsive and respectful- nothing like Fire & Ice company who didn't even have the courtesy to leave a voicemail. I will insist on Rendon next time I need any kind of HVAC service. These guys are for real! read more

My AC stopped working suddenly. With a 4 month old in a heat wave, it was critical to fix it. David Rendon called me same day and tried to arrange immediate service (A+++) When that didn't work for me, we agreed to a time interval the following day. He showed up and fixed my unit in 20 minutes in spite of an emergency on his end. This was a warranty call, and home warranty companies are notorious for shafting the vendors, which sometimes causes vendors to take it out on the client. Not with David. David was polite, professional and flexible, even though he had a pressing personal issue. I highly recommend this service!! read more

10/10 would recommend Rendon! Our air conditioner went out 11 days ago and we were going through our warranty to get it fixed. They sent out some shady companies & ultimately couldn't locate the part to get our AC fixed timely. My husband contacted Rendon on Friday and they obtained the part and were at our house Monday morning (today!) to fix the AC. They were timely, friendly, and very helpful! I am currently 33 weeks pregnant and having our AC fixed was a high priority, and it was clear it was a priority to Rendon as well. We will definitely be using them for any future services needed. read more

I completely understand Rendon Heating and Air being unavailable because they are booked up. We live in an area with very hot summers, and a lot of people have HVAC issues. No problem at all. My issue is with how this business spoke to me. I told Rendon Heating and Air that I was worried because we were about to go through a heat wave without air conditioning and my wife is 30 weeks pregnant. Our pregnancy is a high risk pregnancy. In response to this information Rendon Heating and Air told me "look man we're booked up for weeks, everybody has dogs, everybody has little kids, everybody has problems". Again I completely understand being booked up for weeks. The "everybody has problems" part was a strange thing to say, and I was looking right at my pregnant wife while he said it, knowing that the heat wave was coming. read more

Calling David, not expecting much because I've been calling everywhere for someone to come check out our AC unit on the same day but none have the availability. But David was able to fit our house into one of his technicians, Lupe. Every interaction with both David and Lupe was very professional, knowledgeable, and friendly. When Lupe show up he knows right away what wrong with the units. Everything was fix within hour Lupe show up and my AC unit work as normal again. Very love the service from Rendon heating & air, I will call them again if something else comes up. 10/10 very recommend this place. Give them a call!! read more

David Technician installed the thermostat before calling the insurance company. Then I found out it wasn't covered it was already installed. I had no choice so I paid him. Technician and David's hostility is what got me going. I just told him that it (our heater) still wasn't working after new thermostat. He said I called 10 times which was a lie. I called three times trying to save him a trip. I was trying to explain to him about it wasn't the new thermostat that wasn't working it was that my heater was still having the original issue. He told me f u and hung up the phone would not take my calls again he's a liar. Terrible customer service and communication. My wife reached out to David that conversation did not go well. UPDATED FACTS: Also sent you emails There are always two sides to this matter. David you and I were not there, You choose to believe your technician. I choose to believe my husband. My husband is 81 years old and wears hearing aids. It may appear that he is yelling he just talks loudly. (I attempted to explain this to you during our conversation. You chose not to hear it) The one thing I know for sure is my husband is NOT a liar. Your technician installed the thermostat prior to informing my husband that our Home Serve coverage did not cover the thermostat replacement. Since ours was old my husband paid the $250. My husband admits he did get upset because you and your technician dismissed his repeated calls trying to explain to you that replacing the thermostat did not fix our original issue. Brand New thermostat in off position. Heater fan periodically comes on have to unplug from outlet. Your unprofessional conversation with me went from bad to worse. You bad mouth the company that you are contracted with. Told me you would hit my husband. Threatening me that if I stop payment on the $250 check "you will get your money you know where I live"! Yet you are calling us liars. You cashed the check you have your money. We have a brand new thermostat. But our heater is still not working properly. read more

I called David through my home protection insurance and David was able to get to me very quickly! He was able to diagnose and help me fix my home's AC unit on the same day that I called and coordinated everything smoothly. I would highly recommend him to anyone and would definitely come back again with any future issues! A+ service! read more

I have been a Real Estate Broker for over 30 years and always have dealt with many, many trades people. When we decided to add air conditioning plus change out our old existing furnace we called David Rendon. Liked the fact he is a vet plus a family man. I was glad to see that David himself with one other tech showed up on time. The installation was quick and efficient. David and his tech were professional, courteous and personable. This was a few months ago. Since then both heating and air are operating perfectly. David also explained to me how I could easily fix a wobbly ceiling fan that had been that way for years. I highly recommend Rendon Heating & Air! read more

Excellent service from start to finish! We had a concerning issue with our A/C. David was out the next day and located the problem. Within a week the new parts were ordered and replaced. Easy communication throughout the entire process. He was extremely responsive. Avoid the big guys and save yourself a lot of time (& money) with Rendon. read more

Saw their ad on Facebook. Stood out to me because all of the other ads looked the same, an a/c unit, a van, etc. and Rendon's was a picture of their family. Simple but said something to me. Gut feeling told me to send a message to see if I could have our a/c unit looked at. David, the owner, messaged me back ASAP and scheduled to come out Saturday around noon. Checked out our unit, taught me a few things I should know. We needed a new filter and he even drove down the street to pick up one for us. Service = 5 stars. He's an honest guy and I would completely recommend him. I know we will contact him if we need anything else in the future. read more

David and his company were assigned by our home warranty and I couldn't be happier! He went above and beyond to fix our problem with a leaky furnace, squeezing us into his schedule. He's pleasant to work with and explains everything he's doing. I look forward to working with him again on my next HVAC adventure! read more

David came to my home (via my home warranty co.) due to a problem with my furnace. He diagnosed the problem exactly and was back at my home within a week or so to fix it after the part came in. Great service and great guy to chat with. I will definitely be requesting him in the future through my home warranty company with I have any other HVAC issues. read more

We requested An A/C checkup through our Old Republic Home Warranty policy, and we were fortunate enough to have David Rendon respond to our request. He went above and beyond by making a simple attic fan repair and changing the cold air return filter, which he supplied to us at his cost, receipt provided. He invoiced and submitted the cost of service and materials in accordance with the home warranty's requirements, even speaking to a representative on site to get preapproval for extra needs. Highly recommend. read more

Came out within an hour. Found furnace drain line had popped of. Re installed with a hose clamp and we are back in service. Getting price for full replacement. Happy with all aspects of service call. read more

Highly recommend this family owned business for your HVAC needs! Great communication, very knowledgeable, reasonable pricing, and thorough in their work. They were recommended to me by a friend, and they did not disappoint! read more

Our heat was shutting off, seemingly randomly, and we submitted a request through our home warranty to have this resolved, and Rendon Heating & Air was the company that was contracted. Rendon fit us in the earliest possible availability and came out on a Friday to attempt to fix the issue with our furnace. Within a few minutes the technician, Chris, had addressed the issue, discussed what he did, and went on his way. I was happy with how he performed and also how he explained what he thought was the issue. Part of the solution was based upon my description of what I had noticed happening. So we were happy it was resolved so quickly. Unfortunately, the same issue came back that following evening and I messaged Rendon the following morning (a Saturday) to see if they knew what else might be happening. I was a little bummed that the issue recurred but also realized that their solution was at least partially based upon my description of something I had noticed. The issue I described might have been partially to blame for entire problem, so was something that had to be addressed. So I do not fault the technician for possibly missing a different or larger issue. Rendon replied early the next workday (Monday) and we scheduled for just two days later, which was entirely reasonable to me, especially during Thanksgiving week. The same technician, Chris, came out early and helped fix the main issue and were on their way only after staying around a bit longer and having a second technician, the owner David, stop by to verify the fix. We were not charged for second service call, which honestly might have been justified. I really appreciated that they quickly set up a second visit, including having David stop by, resolved the issue, and then explained to me the main issue that they addressed. Lastly, both Chris and David were friendly and responsive during all communications over texts or in person. I would highly recommend Rendon Heating & Air. read more
