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

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

If you're not 100% sure that you really need a new HVAC system talk to John at high performance before you get sold a new system you don't necessarily need yet. It almost happened to me. There are a lot of unscrupulous HVAC companies out there that May not even know how to diagnose a system but are good at selling new ones. I know because it almost happened to me 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

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

Johnathon provides world-class service! I've consulted with him twice about furnace issues, and his expertise is second to none. (He even took my last call while he was waiting for his dad in the Kaiser parking lot) He diagnoses problems with surgical precision and offers honest, effective solutions. If you want a professional who truly enjoys his craft and treats customers like gold, Johnathon is your guy. Customer for life! 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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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 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

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.

A/C and fan stopped working. Of course I called John again. And just like before, he was prompt, professional, smart, and as helpful as could be. All at a reasonable cost. Recently a neighbor called John at my suggestion and was also amazed at the service. I'm sure there are some other outstanding heating and air folks out there, but the way things are going I'm never going to meet them! read more

John has been helping me with our HVAC issues for many years. Our system is very old but John, magically, keeps it going! John is extremely knowledgeable about everything that is HVAC (vendors, brands, systems, operating matters, etc.). He is also very passionate about sharing his knowledge and advice with his clients. I consider him as an exceptional authority and a great advisor on HVAC matters. John has also been very prompt in responding to our service needs. Moreover, he is honest, trustworthy, and a great human being!! read more

John is top notch. Straight to the point and provides a transparent assessment of what is going on. Well organized service van (with no advertising adorning the outside) and good compliment of high quality tools and parts. He communicates effectively and provides a good summary of what happened, what is going on and what to plan (not expect) for the future. He has developed a long list of satisfied customers through his integrity and hard work. read more

I'm leaving this review for my daughter. She has an 805 sq ft condo, and her air conditioning and heating systems are over 30 years old. She got a quote from a very well known firm to replace her systems for $18k! Her cooling system was the problem, but they said she needs to replace both the heating and cooling systems. There is no question she will need them replaced sometime soon, but we were shocked by the quote- and how they conveyed a sense of urgency to replace it now. Also, she needs the smallest systems they make and that sounded like the kind of quote I would get for my 2200 sq ft home! I told her she needs to call John! John came out , looked at her systems, allayed her fears. He did say that yes, she will need to replace it someday- maybe tomorrow or maybe a year from now; but he was able to get it running to hopefully give her time to look around, and get competing quotes. She also didn't need to replace the heating unit at all this time at all. Whew. He's the best. Thank you John! read more

I wish I could give 10 stars :) John is fantastic and I personally recommend everyone use his repair services for any HVAC issue. He is prompt, honest, efficient, and reasonably priced. You won't find a better HVAC repair person anywhere! He has been our goto person for all heating and cooling for everyone we know for the past 10 years and every experience has been perfect. read more

John was responsive, helpful, and reasonably priced. My husband replaced the circuit board on our 29-year old furnace. He was stumped by a few remaining wires, but John was able to guide him via phone on placement. Just in time for a recent heat wave in the East Bay. read more

My AC had stopped working and after asking around for recommendations the group of home owners in my area recommended John from High Performance. He called me back promptly on my phone and was able to find the root cause over the phone. Basically the AC unit was working fine . There was an issue with the thermostat which had to be replaced. I replaced the thermostat and ran into human error on my end- sent him pictures and he helped me find the issue. And now I am enjoying cold air in this heat. Thank you John! You are the best! TLDR- if you have AC issues call John, you won't regret it. read more

I cannot recommend this company enough. It is one guy and all he does is maintenance and repairs. What I like about this is he will give you the truth about everything and because he doesn't do installs he won't try to upsell you. If all you need is a repair or maintenance, please go to him because every other company we checked out told us we needed a new system, even though ours was only six years old. read more

My furnace failed and I call John at High Performance Heating and Air. I told him the symptoms and the fault and he know immediately what the problem was. When he arrived, he got a new capacitor out of his truck and went up the ladder to where the furnace was. He tested the old capacitor, and sure enough, it was bad. So he replaced it with the one he brought with him. When we turned the power back on and it started right up. The total repair time was about 5 minutes. For him to know what was wrong from just a phone call I find quite amazing! He sure knows what he is doing. I suggest you call John first before you waste your time with others. read more

HPH/John's phone number has been added to my list of numbers not to lose for my home. In addition to his high quality of work and his effort to help us as soon as possible, I was especially impressed by his transparency as to the expected costs for his services. HPH's website is a great read and listen for this issue and others items including providing advice as to a wide variety of HVAC items. Overall, HPH provided great value with a clear understanding of the costs for services. In the same fashion as my referring neighbor, I will pass along HPH/John's contact information in the future if anyone asks me for an HVAC repair referral. read more
