Honest, reliable, reasonable pricing, and just a genuinely nice guy. I wanted to repair my gas furnace (original from 1995) and since John specializes in repairs and not replacements, I knew he was the guy I wanted to call. He was able to quickly identify the problem and had all the parts he needed in his truck. He was not pushy on selling anything, he simply had a couple of suggestions on small parts to replace before it went bad as an optional fix for an affordable price, and I appreciated that. If you're looking for an honest HVAC tech who will genuinely try to repair the problem and not tell you to replace anything, call John! Be sure to check out his website if you want to learn more about his pricing. He's the best! read more

I was very pleased with the service. The technician- John diagnosed the problem, replaced the failed capacitor, and checked the system afterward to make sure the AC was operating properly. He was professional, explained the work, and got my AC running again. I appreciated that he did not pressure me into unnecessary repairs. The price was reasonable, and I would use this company again. read more

John to the Rescue AGAIN! Unfortunately, our AC's refrigerant leak was much worse than we hoped, and it stopped working during the heat wave. It was hard for me and my husband to deal with the heat, but it was so much harder for my dogs. When I reached out to John, he did not only get back to me right away but quickly came to add more refrigerant to our AC. Now my dogs are so happy and comfortable that they have been playing all afternoon. He also provided us with some advice as to how to chose a new AC unit, installers, etc. John is so knowledgeable, and I am so grateful that I have met him. He is honest, trustworthy, and very fair. Oh he is super punctual too (so that you don't have to waste your time on wondering when he shows up). I definitely recommend him! read more

High Performance Heating & Air - John is working on our AC. Thank you, John! - Heating & Air Conditioning/HVAC Near Me

So happy I found John on Nextdoor! I read through his website and decided that this was the person I needed to diagnose my ac. My ac is from the 1980's and was making a very loud sound so much that I couldn't run it. John fixed my ac and it's been running great. Read through his website as it will answer a lot of your questions. Trust his judgement if you are looking for someone to give you an honest diagnosis. read more

Caveat: John did not work on my house, but spent a good 15 minutes talking to me on the phone about options for my situation, and gave me some information about furnaces and changing CA laws of which I was unaware. If I *did* have a unit that needed repair, I'd call him. read more

I've used John for a couple of A/C fixes. He's extremely knowledgeable and transparent with pricing. He has also been very responsive and generous with his time to explain things on the phone. A fine addition to the Rolodex for your "A/C guy". read more

This is my third time using High Performance Heating & Air to repair our central air conditioner in several years. I have no doubt in having John service my AC unit. He is exceptionally bright, knows his craft and very honest in dealing with his customers. He does not try to upsell you on buying new products or additional service. Our AC was not blowing cold air two days ago when the weather was reaching over 100 degrees. I reached out to John the next day and he promised to do the service call first thing the next day. I told John that maybe our AC needed refrigerant because it was not blowing cold air, but John caution me that it could be something else besides refrigerant. He was right, it was a blown fuse after his diagnostic investigations. He also help discovered that we had some air flow blockage and that turns out we had a very dirty air filter. He gave us a new air filter to change the old one out. Overall, I am very impressed with John's technical expertise on HVAC and I trust his judgement and recommendations. I will use his service again whenever I have problems with my HVAC unit. read more

I called Johnathan on a Sunday expecting to leave a voicemail and hear back on Monday, but he picked up right away and immediately began troubleshooting my furnace issues over the phone. He asked direct questions and requested photos. From the limited information I was able to give him, he determined that the system was overheating and provided an extremely reasonable quote to fix it. He showed up the next morning within the time window he had given and sent multiple updates about his arrival time, which, as a mom of a 9-month-old and with two excitable dogs at home, I really appreciated. The system turned out to be overheating, just as he suspected. I stayed nearby while he worked, and he explained everything he was doing and why. Johnathan was able to dial the furnace into perfect working condition and offered helpful tips to keep it running smoothly. It's very refreshing to have a true subject matter expert working on your home. I will absolutely hire him again in a heartbeat. read more

Simply put, John is the best, and always has been when I have had to call on him. Prompt, very knowledgeable and a nice guy. What more can you ask? read more

John is great! He fixed our furnace and explained what needed o be replaced. Unfortunately I was away the last time we had an issue so we went with another company. I'm sure we were overcharged. Up front pricing-no BS. Highly recommend him! read more

Aside from expansive HVAC knowledge and seasoned expertise, what's equally impressive about John is his strong work ethic. As a substantial number of reviews note--and ours will as well--he's dependable, committed, punctual and possesses great integrity. Unlike other HVAC contractors who upsell their customers, John's central focus is providing quality work at a reasonable price. In fact, he initially troubleshoots via phone to help guide with fixes customers can potentially do themselves. However, for us, the furnace repair was more involved and required John's mastery. He swiftly diagnosed the problem and invited us to watch/learn about the repair he was performing, just as he does for all customers. Without question, John is exceptional and thus highly recommended for anyone in need of HVAC repair. read more

Jon is simply awesome! He was able to figure out the issue in a minute ! Whereas the other HVAC company spent a lot of time and recommended to replace everything. He saved us a ton of money and time read more

There aren't many tradesmen like John around anymore. Honest, knowledgeable and friendly. I called John about my AC suddenly not blowing cold anymore and he carefully walked me through what could be the issue since he couldn't make it out until tomorrow. I'm a DIYer when I can but I was prepared to pay someone for diagnostics at the very least since I was out of ideas. In the end John was absolutely right, it was the dual capacitor failing on the herm/compressor side. I was able to fix and replace it myself with John's expertise. Highly recommend! Although he didn't come to fix the issue, I can tell that John definitely takes pride in his work, fixing and helping people. I'm not sure how expensive he is, but I know he'll always be cheaper in the long run because he knows exactly what's he's doing and will do it right. Thanks again John! read more

Excellent at what he does, you can count on Jon - honest, reliable, & obviously very knowledgable .. you can't go wrong.

John with High Performance did an incredible job fixing my AC! He was highly professional, thorough, and knowledgeable from start to finish.Quick tip: Don't let his straightforward demeanor through text discourage you from using his great service! Once he arrives, he is fantastic to work with.I was so impressed that he had all the necessary parts on hand right in his van. He diagnosed the issue and fixed it immediately during the very first visit. On top of the fast service, his pricing was very reasonable when the job was done.I truly appreciate your excellent service, John! If you have any AC needs, I definitely recommend calling John. read more

I've used John several times to service our furnace and air conditioning. He is a great communicator, explains what the issues are and is very thorough in his repairs. He responds immediately and always tries to fit us in to his schedule as soon as he can. Lastly, his truck is stocked with parts, so he has always had the repair parts available. I've recommended him many times to friends. There is no one else we would use! 5 Stars!!!! read more

After having another tech top off my HVAC coolant, my HVAC line froze. This was when it was 100 degrees out in August. The tech didn't know what was wrong, so I called John at High Performance. I wasn't even a customer yet, but John was diagnosing my issue over the phone and suspected it was lack of air flow. I had John come out and he looked at everything. It turns out the air flow was an issue because there was dirt and plastic bag debris (from previous owner) inside the control unit next to the furnace (happens from not using air filter). This thing could have caught on fire! That whole part of the unit was taken off and cleaned. He also replaced the capacitor. The coolant was also not completely topped off! It has been many months and no issues so far. John is highly knowledgeable and takes pride in his work. I wished I had called John in the first place, which would have saved me money and stress from not knowing if my issues can be fixed or if I need to replace my HVAC! Plus, we had to endure the heat! read more

The first storm of the season hit today, and I turned on the heat for the first time in months. After an hour I realized the temperature hadn't changed, the furnace wasn't working. I called John (who fixed my A/C in 2017). He asked a few questions, told me the most likely causes and range of costs, and was able to come by in the afternoon. I watched him do the diagnosis, and his guess was right - there was a failure on the circult board on the 25-year-old furnace. He had the part in stock in his van and was able to replace it. John only does repairs, not installations, so he has no incentive to sell you a new system. Meanwhile, I got an education from him on the problems with newer state-mandated furnace and heat pump technology, and on how to improve air flow. One example - if I do decide to or need to replace my 25-year-old system, he recommended sealing the wooden platform under the furnace so it stops pulling air from the garage instead of from the return register that connects with the platform. read more

If you want a professional who truly enjoys his craft and treats customers like gold, Johnathon is your guy. Customer for life! read more

Quick response and very professional service. I appreciated the honesty and documentation of the work as I couldn't be there personally to check. I will be using John going forward. read more

We were told by another big service and repair company that we needed to replace our furnace right away due to various things. We called Jon for a second opinion and after a very thorough inspection, he basically told us we had been handed a plate of hooey. He found none of the problems we were told the furnace had. He also cautioned that wasn't to say nothing will go wrong in the future, but there is no way to know that. He saved us thousands of dollars. Jon is extremely knowledgable, he explained things clearly and is a man of high integrity. read more

John is extremely knowledgeable and helped me understand the type of heating & air unit I should install in my home. He has a strong background in the business and I admire how dedicated he is in his line of work. He is not "salesy" and was a pleasure to work with. John, thank you for everything! read more

Look no further john is who your looking for, great guy and knows what he's doing and knows how to convey your issue. Im usually pretty skeptical of contractors but there is nothing about john that gave me that feeling. Only hvac guy I'll call going forward, thanks john read more

John delivered personalized and responsive service with a quick turnaround on communication, inspection, and repair - exactly what I'm willing to pay for. No BS, no upselling, no fear tactics, just honest communication and deft hands on action, exactly what I needed/wanted. read more

After years of having issues with our heating we started looking for an honest and reputable HVAC. We are so thankful for these reviews as that is how we decided to give High Performance a try. We are new happy costumers and appreciate the expertise and knowledge we found in Johnathan Youngs. He is truly the best in the area!!! read more

I've known John for many years now. Ten, in fact. During those ten years I have observed a continued effort on John's part to solve any problem set before him cleanly and efficiently. He does not make promises he won't be able to keep. He tells you exactly the truth of your problem, and what he can reasonably do to solve your problem, all within a very reasonable cost. It is therefore clear to me that my initial impressions of John when I had met him a decade ago have remained consistent throughout the years, namely that he is, first and foremost, a logical and intelligent mind, and a problem solver at a very high level. I suspect that he enjoys solving the puzzles, and gets satisfaction of doing a job well done on behalf of his client, and (at the risk of sounding too saccharine) of also making the world a little bit better of a place than when he first found it, taking the problems that we find frustrating and confusing, and eliminating them in his usual stoic manner. If that isn't the very essence of professionalism, then I really don't know what is. John is an expert, plain and simple. If you want a job done right, then you're going to want a true professional, and that is John from High Performance Heating & Air. Save yourself the hassle, and call him before you call someone else. read more

As always John was very responsive and got my heater back on-line on the same day I called. I especially appreciate that he explains what he is doing and why so I can maybe avoid having to call th next time. read more

John was able to give me a good idea of what was possibly wrong and estimated cost over the phone. At the appointment he was very efficient and had the air conditioner repaired quickly. His fees are reasonable and he had a lot of good advice. He changed the furnace filter and looked the unit over and made adjustments at no extra charge while he was there. Great guy! read more

My HVAC stopped generating cool air so I reached out to several vendors. The first tech from a company named Jazz came out and for $59 they basically told that me I had a short circuit (not true) with R22 refrigerant (hard to find) and needed a new unit. The tech said "I can get you a quote if you are ready to replace it today" Shortly I was given a $18k quote for the HVAC plus furnace.... I decided to get a second opinion with John from High Performance. In 30mins he repaired the capacitor and my unit was up and running. What a world of difference... I highly recommend you call John if you need a repair. read more

The service was prompt, and my heater was repaired the same day. John is very knowledgeable, quickly diagnosed the issue, and saved me a lot of money. I highly recommend High Performance Heating and Air. read more

John is the person who is truthful and honest. You can depend on his analysis and judgement. He knows everything about any HVAC and will explain in detail to us. It's so interesting that we feel that even we did the work with him. He doesn't charge you unnecessarily and only to the work done. Final verdict. John is awesome, smart, dependable, honest, truthful and no over charges ( thank you). I have been knowing him since 2015. You will never regret calling him to analyze any HVAC and he knows his stuff. Thanks John for always helping us out. read more

Once again John came through for us. He even put us in touch with an HVAC contractor to install a new coil after he diagnosed the leak.

John was great from the beginning to end. Didn't cut any corners and was very knowledgeable. Felt very comfortable that he was doing the right thing and he provided great feedback and recommendations. His prices are more than fair. Highly recommend! read more

I highly recommend John. All the 5-star reviews echo the same thing about him. He's very knowledgeable, straight forward, meticulous about his workmanship and very honest. I'm very particular about contractors and can tell within 5 minutes of talking with them if they know what they're talking about. John is a highly knowledgeable and skilled HVAC technician. If you need to service / troubleshoot your HVAC system, call him first before engaging with anyone else. Everyone else wants to upsell you a complete new system because they don't have the skill and knowledge to service your HVAC system like John. read more

Had an issue that had been lingering for about a year, with another company coming out around six times, unable to fix it. Called High Performance and John came out and fixed it in one afternoon. Was very pleased with the pricing as well. His diagnostic fee was higher than most, but he tells you that upfront. When the repair was complete however, I still came out paying less than prior repairs by, "Less expensive," vendors. I was pleased to do business with him and I will definitely use his services again if the need arises. read more

John is one of the few servicemen left with honesty and integrity. He was very prompt on answering his phone, getting back to me and coming out Monday after a weekend call.He was very straightforward about our options which I appreciated. He recommended a company I could trust for installation and get an estimate for the work needed. So if you are looking for someone who is honest with you and no BS John's your guy.

High Performance Heating & Air - Heating & Air Conditioning/HVAC Near Me

John knows his stuff. He was there to answer my questions and walk me through a possible fix. When that didn't work, he was available the next day to come over. Helped get my A/C up and running. Thanks John. read more

Needed my air condition unit check so it will be ready for the summer grind. Called John to get a price qoute on the check up and right away John taught me on how this other HVAC companies work when it comes to air condition unit check, i was impressed with how thorough and honest he was and so i decided that he would be the right guy to check on our Unit. We agreed on the date and John was able to check our Unit and discovered that it was low on freon as well as a capacitor that was not the industry standard. He was able to add the freon and replace the capacitor with a better one . The price that he charge was pretty reasonable as well. If you need HVAC repairs i would highly recommend that you call John. Thanks again John. read more

We have always had an excellent experience with John. He is very responsive and has always had the parts my old air conditioner needs with him (so no waiting for repairs). As well, he charges a very fair rate. He will continue to be our first call for all HVAC repairs. read more
