Spoke to Roger from stability. He is detailed and amazing with his explanations. The amount of insight I received is holistic. Stability gives out free quotes on its assessments and does things by the book. I am confident that his way is the right way to go. Make sure this is your first stop! read more

Excellent customer service! Honest, reliable, reasonable! I needed help with replacing a thermostat on my heating/air conditioning, and Roger did an excellent job! I highly recommend! read more

Roger was everything you could hope for from a service provider. Very knowledgable, conscientious, timely, and straightforward. He took time to explain the problem, fixed our furnace and gave us tips for future care. A plus! read more

Strong recommendation for Roger Cornavaca at Stability Hearing and Air. In the midst of our last heat wave, our AC fan stopped working. I selected Stability because he's local and had consistently good reviews. He answered my call right away and came out the next morning at 8. Both days he had to come out he was on time. His truck was well supplied and he was tidy doing his work. He assessed the situation as a bad capacitor which he had with him. He noticed the fan motor was leaking oil so I had him replace it since it was 18 years old although he said it might last awhile longer. By then I trusted Roger. He called 4 places to find an original new motor and drove a long way to get it. He arrived the next morning on time. He made sure the unit was holding coolant pressure and gave it a thorough inspection and cleaning inside and outside. Roger explained my options, costs and the process. He was trustworthy and I will use him to service our heater when the temps get colder. As I mentioned, the heater/AC are 18 years old so they finally deserve some care. I highly recommend Roger, family guy, local, owner. Tell him Santa sent you. read more

Of course as soon as we turn our heat on this winter it didn't work. Our landlord called Roger but he didn't have availability for 2 weeks. In the interim another company came to fix the issue which only resolved the problem for 4 days. We ended up waiting another week for Roger to come and I'm glad we did. Not only did he restore our heat, he wore shoe covers (which I am so appreciative of as the other company did not), and he swept up the small mess that was made before he left - both inside and outside! He and his team went above and beyond. If I ever need heating/cooling work done again, I know who to call! read more

They never showed up. What can I say here. We were left with hot air for says. They are not stable-ity Heating Nor Air !

I was very impressed and satisfied with our experience with Stability Heating and Air. From the first phone call to get a quote for a package unit A/C "tune-up" to the completion of the job, Roger was professional, courteous, and clearly knowledgeable. He arrived a few minutes early to ensure he could arrive at our door right on time and was even polite enough to wait in his van until the scheduled time so as not to disturb us. That goes above and beyond courteous in my book! Roger was articulate and polite--something so rare these days--so I was fully comfortable that I could communicate clearly with him. He was even sweet to our 2 year-old, letting him "assist" him with light equipment during his work (to our son's delight!) He worked efficiently yet carefully. Afterward, he took the time to explain what he did and what he found, inviting my husband to join him on the roof to show him exactly what he was talking about. And for all this, a very reasonable price! I called several other companies and no one even came close to the rate Stability charged. But, in the end, it was the professionalism and courtesy evident in that first phone call that made my choice. I highly recommend Stability Heating and Air! read more

Great job, professional work, amazing people. They did a upstanding job. We're 100% satisfied Very affordable price We recommend to anyone Thank you so much read more

Having been in the service industry my entire career, THIS is the company you want!!! I had a problem with my AC and called Stability Heating & Air. Roger came out on time and with his 18+ years of experience professionally diagnosed the problem. I needed two parts, one that he didn't have, so he called and went and got it. His price was very fair and he didn't try to oversell me on things that I didn't need. If you need repairs on your heating or AC, you'd be foolish not to give Stability Heating & Air a call. read more

Professional installation of a furnace in our home. Would recommend Roger for heating.

I decided to start my research for furnaces by visiting Ferguson Enterprises since a friend of mine who distributes Trane products in Louisiana said they were excellent. Of course he is biased but a quick online search confirmed his claim. A Ferguson representative introduced me to Roger who happened to be shopping. After receiving Trane brochures from the store Roger showed me photos of his work and stated that he would be happy to give me an estimate after he finished shopping. Of all the estimates I received, Roger's was the most comprehensive and walked me through areas where he thought he could add additional value beyond just replacing our aging furnace. After I described my issues with the old furnace, Roger described what would make the greatest impact and built my quote around those suggestions. He is also very proud of his work and his excitement shows when he shows you pictures off of his ipad. On installation day, Roger placed tarps wherever he needed to step and was very careful in removing my old equipment from the attic. At the end of the day, Roger is very conscientious about cleaning up and organizing his work area. Construction being what it is, I still vacuumed after he left since I wanted to make sure I got as much of the attic insulation as possible. I ended up installing a Trane XT80 furnace, adding a new vent in my living room and replacing all the ducting and register vents. The old furnace was oversized, not properly secured and had leaks at each vent that attached to the plenum. The old ducting was laid across the attic and looked disorganized. Roger suspended the furnace and ducting from the roof which opened up the attic and made a large platform that could be used to service the furnace. Roger's price was very reasonable when compared to the competition after considering their quotes only included the furnace replacement. The new furnace is extremely quite. Roger took extra steps to make the return ducting longer and added rubber bumpers from where he suspended the furnace to reduce noise. I highly recommend Roger for his honesty and experience. He does accept credit cards but passes his transaction fee that he is charged back to the customer. read more

With temperatures in the nineties, my AC suddenly went out. It's an older unit, installed 13 years ago. I called around and was told everyone was too busy to come out for a week or longer and it would cost me at least $100 to make the trip. Roger at Stability however made a quick trip over within the hour to give me a free estimate. He quickly identified the problem. Instead of trying to sell me a whole new unit, he showed me how the old drain pan under the evaporator coil in the attic was leaking into the secondary (backup) water collection pan, causing the unit to automatically shut down. Given the age of the unit, and my financial situation, he suggested I could simply remove the cutoff switch and redo the plumbing to route the water out of the secondary pan to the drainage system. That would avoid the cost of replacing the indoor assembly. Good enough until I do replace the whole system in a few years. I tried to pay him for his time, but he refused. Instead, he said to remember him when it came time to replace the unit. I will. What a prince among men! read more

This is a delayed review of work that Roger Cornavaca and Stability Heating did in replacing a furnace and old flex ducting. Roger's bid was well toward the low-end and his statement of work clear and understandable. Any questions were answered in detail and it is apparent that he understands the trade very well and is equipped to provide options and trade-offs with regard to equipment and installation. He provided a new 2-stage furnace and all new flex ducting with multi-adjustable registers. He removed the old in-attic furnace, made some changes to the mounting for sound isolation and ran duct to some difficult areas of access. He explained the purpose of doing things a certain way and relocated registers for better heat distribution. In all aspects of the job, he was meticulous and sensitive to our concerns and questions. He cleaned up each day and left the jobsite in good condition. He did a few things out of the scope of work with out charge. Though this work was performed in September of 2017 and he warrants installation for a year, he came by today to make some tweaks to the air distribution by adjusting dampers and registers and making recommendations to optimize the furnace performance. The furnace carries the standard manufacturer's warranty. We are quite pleased overall with our updated heating system and would unconditionally recommend Roger and his team. read more

Roger is amazing, fantastic service and repair. My air conditioning unit went out, he was prompt, knew exactly what the problem was and fixed it!! He is my go to guy for all my heating and air. I highly recommend him! read more

If I could give more stars I would, Roger is great, very knowledgeable and patient. He explained everything in detail, and was very reasonable. Would recommend Roger in a heartbeat. read more

All I have to say is Stability HVAC is LEGIT. Prior to calling Stability, out of desperation (for 1 month it was so cold in my home I had all four kitchen burners on), I called a random HVAC company out of telephone book to come out. They were 6 hours late!! And quoted me a price into the thousands!! And before doing any legitimate troubleshooting, stated that I needed a new furnace. They used a scare tactic stating that my furnace was old, that it would emit deadly CO2. Not cool. Not feeling good about any of that, I looked on Yelp and found Stability HVAC. Spoke to Roger, who was super nice. Over the phone, I had good feelings about him. I've been relying on the feels lately and they haven't let me down. Not only that, he was able to see me the same day and was on time! Can't overstate how being on time here in Los Angeles/Southbay is so important. That made me feel even better. Roger came out. Unscrewed some panels, poked around, and troubleshooted the problem. He had the part in his van and fixed it right on the spot for 1/4 the price the other company quoted me. On top of that, I mentioned that my AC wasn't working. While he was in there, he noticed a plug was loose. Plugged it in. And my AC worked!! I couldn't believe that I was sweating in my home for the summer of 2016 because of a loose plug. Stability's service and honesty is on point! Thanks for the good feels Roger and Stability HVAC. No more huddling around my stove this winter in a beanie and fingerless gloves. read more

Roger and his assistant last month replaced my 30 year old a/c unit and furnace. When Roger came to my home to do an estimate, he explained everything in detail and showed me all the options and did not pressure me to anything. I had 3 previous estimates from 2 mayor stores and another small company and they were all over-priced, did not explain the details, did not make any measurements and did not give me options for my units to be more efficient. I felt as though these companies were just interested in the commission and tried to pressure me to sign a contract the same day. When Roger from Stability Heating and Air quoted me for the job I was extremely shocked at how resonable his prices were and I told him twice are you sure that is the price for everything and he explained that there were no hidden fees and his work was guaranteed. After looking at all my options, I knew that Roger was the right guy for the job and showed me his credentials for the past 15 years and all the residential and commercial work he has done. I strongly believe that every unit will work exceptional in any home but what really matters is the installation of your units, this person has to be highly qualified and provide quality work too and I knew after discussing all our options that Roger was going to do the job right especially with the whole relocation of our units. After accepting Rogers offer with no hidden or extra fees I loved all the extras he put into this job to make sure my units were going to be at their best performance and he relocated the units as they should have been in the first place and did not charge me extra as the other companies would have. Roger was always on time for the job, cleaned up after himself, and worked on the job like he was working on his own home. Roger made us feel like he was family and I knew I can trust him and his crew as I had to run errands throughout the days. If Roger felt there was going to be any hiccups in the attic of putting certain vents or pipes that needed to be moved, he always gave us more than one option to accommodate for the unforeseen work. I would definitely be using Roger for years to come and will also be accepting his yearly maintenance on the units. If you are truly looking for reasonable price but high quality work then he is your guy, he is truly honest and a pro at his work. Roger my family wants to thank you for coming in and doing an exceptional job, we are extremely blessed and happy with our new ac unit and furnace all because we had the right company do the installation Stability Heating and Air you rock!

I highly recommend Stability Heating and Air. Roger and his team put a brand new air conditioning and heating system into my house, including all new piping and vents as well as the electrical and gas lines. They were extremely professional, thorough, and efficient. I had a number of other places come out to give me an estimate. Roger's estimate was very competitive and he took more time than any of the other companies to walk me through a very detailed plan. His follow up and attention to detail gave me a lot of confidence going into an installation process I have no experience with. The installation process was very smooth. Roger consulted with me at every step of the process, making sure I was fully on board with all decisions being made. He and his team went above and beyond to make sure things were done right and Roger took the care as if he was working in his own home, not just trying to get through the job. I definitely recommend Stability Heating and Air. read more

Roger is top notch! This past winter our heater went out. I called Stability, unbeknownst to me that Roger, the owner, picked up the phone at 6:30 PM on a Friday night and was willing to come out and check my furnace by 8:00 PM that night! Who does that!? I was in awe at his commitment. Roger showed up early the next day, performed a thorough inspection, gave me plenty of options and answered all of my questions. My instinct said go with him immediately. He could have installed a new furnace within a day or two. Sadly, I contacted two large companies to get additional estimates, thinking I'm doing proper due diligence. Their visits were the following week. The first appointment was a NO-SHOW! When I called the office, the tech said he would be about an hour late. Still, an hour later no one came. I cancelled the appointment. What a waste of my time and my house was still cold! How could I pass up Roger? I cancelled the other appointment for later that week and called Roger immediately. Now, Roger is booked all week and I know why - he's an ace! The installation was set for the following Saturday and he had to drop by the house during the week. Roger called to inform me that he might be a few minutes late. *Large corporations take note! Common courtesy and professionalism is imperative to happy customers and excellent reviews!* I didn't care that Roger was running behind. I care very much that Roger had the decency to call and give me an update. What a great guy and very professional! Installation day came and sure enough, Roger and his team showed up early. His installation was exactly how he said it would be. His team was courteous and professional. The area around our new furnace was cleaned better than when he arrived. Our house has a powerful new furnace installed impeccably by a courteous and professional company. Roger, you're the best! I recommend you highly. read more

Roger was recommended to us by friends that recently got their furnace replaced by Stability Heating & Air, the day that Roger arrived to our new home to give us an estimate to replace our furnace, we knew that we were dealing with a professional and honest individual. Roger and his assistant replaced our 25 year old furnace all in one day, what a job well done! I must say that Roger takes pride in his work. Not only was the job completed in one day but the cleanness and detail of the new furnace installation was remarkable, would highly recommend to anyone looking for honest and efficient work. Thank you Roger for an easy and pleasant transaction. read more

These guys are great!! After calling a few place to check my hearing and AC unit in my new place, Roger was available same day to come and check things out. I really liked that as he was troubleshooting my system, he would tell me step by step any issues and if he would charge for the fix. At the end of the day I ended up getting a new Trane furnace and AC units in my condo and Roger gave me a very fair and reasonable price. He started the work with his assistant 2 days later and was quick and thorough. He did such a great job one of my neighbors asked him to stop by after he finished with my installation. Stability is the real deal and I would definitely recommend them for all of your heating/AC needs. read more

Roger recently installed new vents and central air conditioning in our home. Even providing the quote he was very helpful and spent time explaining the process to us. His work was meticulous and he made sure we understood what he did and why. We highly recommend him. read more

Roger was great! He was very helpful in explaining all the options and making us feel comfortable about what we were purchasing, especially as first time homeowners. The process was super easy and he was clean and efficient. Would totally recommend to anyone looking for someone honest and knowledgeable! read more

I came across Stability only by chance when I searched for a commercial A/C company on the internet that services Torrance. Roger was knowledgeable about my situation and the 18 year old commercial A/C unit I currently have on my rental. Roger took his time, explained everything to me as he went along, and was forthcoming with his fees which kept from any surprises. I would certainly use Stability Heating and Air again and would highly recommend them to anyone. read more

Roger was recommended to us by a friend and we were very happy we reached out to him! He and his team completed a new installation at our house in March in about a week's time, also completely removing a 50+ year old floor furnace. He explained everything that he did along the way and even made sure to clean up each evening before leaving. Highly recommend! read more

I was referred to Stability heating and air by a couple of reputable guys in the hvac industry. After contacting Roger from Stability for a free proposal on a 2 ton unit for my home. I was sold within the first 5 minutes of Roger's explanation and science on how a proper system would be beneficial for my home. Prior to having Stability over. I did have 3 other proposal that range from $5800 to $15000. None of these company reps. had nearly a fraction of knowledge that Roger from Stability had. He was professional, clean, though rough and very knowledgeable. After all that he finally showed me pictures of his completed projects on his iPad. I was very impress on how neat his work was. I almost thought many of the pictures he showed me were photo shop. My wife and I did not have to discuss much. We both knew Stability heating and air was the company to hire. After all said and done Stability was cheaper than every company we had over. Our unit was installed and fine tuned by Roger and his crew 4 days later. My wife and I are super happy with all of Stability's work. Hands down! The best and easiest hvac contractor I've ever dealt with. Highly recommend Stability heating and air for any hvac work. read more

I had the pleasure of meeting the owner and his Forman after requesting an estimate for a furnace overhaul. I was overwhelmed by the amount of information required to make proper decisions. Roger really took his time and explained everything. He could have sold me equipment that would have been overkill and costly. He measured every room and researched my needs intensely. Once completed, Roger and Richard explained very patiently as to how our new system worked. Even after he left, I called him hours later because I was confused. Without hesitation he said he would be right over. I would highly recommend this company as we were thoroughly impressed. read more

Super reliable, great service and very reasonable prices! I highly recommend them! It's been a struggle to find someone so glad we found this place! read more

I highly recommend Stability Heating and Air to anyone contemplating replacing an existing furnace unit. I called to inquire about an assessment of our existing unit which was making a very loud "clicking" sound and spoke to Roger. Based on my verbal description he described the possible issue however, we scheduled a time for him to physically come over and assess in person. His inspection was thorough and he explained and showed me the issues. I had done some previous research and his assessment was consistent with my finding as well. I elected to have our unit replaced and the whole process from that point was flawless. The job executed in a very professional and neat manner. read more

Roger with Stability Heating and Air did a fantastic job in installing an AC unit in my two story home. He is honest, reliable, and completes a very clean job. Thank you so much, I would highly reccomend Stability Heating and Air. read more
