The technician Michael is extremely rude! Received a voicemail that he would be at our house between the hours of 9am- 5pm on a Monday. I called back to ask him if he could provide a time frame as I had other appointments and would need to make arrangements. He responded with "Mame, I can't tell you till Monday". I asked him if I could tell him what time my sons CHOC (hospital's specialist) appointment was on Monday figure out if Monday would even work and He said " Ma'me, I can't help you and hung up on me". Seriously?? So Sorry my sons medical condition is an inconvenience to you...? After reading Michael's reviews on this site, his attitude seems to be on par with his service of their treating customers base as disposable. I can only imagine how bad they treat you once they have your money in hand or if they make a mistake on their end. Yikes! Good luck using this company! read more

I had an HVAC system in my residential townhouse where the heat would turn on fine, but the air would not cool (the heat exchanger outside would turn on, but cold air would not blow from the house vents). I checked the air handler unit in the attic and determined that it was getting cold, but that the fan was not blowing. Since I knew the fan worked with the heat, I knew it must be a wiring issue. The house is not old, and the wires are solid copper so I knew the wires did not need replacement. Whomever was to do the repair just needed to move a wire from one screw terminal on the circuit board strip to a another screw terminal). There were only five or six wires running from the thermostat to the air handler, most of them were already working properly, so it was clearly an easy job. I figured why not pay a professional his or her service call fee, just to make sure it's done right. I called Summit based on Yelp reviews. When I called Summit, I was advised of the approx. $100 service call fee. That was reasonable in my book. George said the service call fee included 45 minutes of troubleshooting and fixing. With the unit generally working, the wires clearly not needing replacement of any kind, etc., any professional could have easily fixed it within that time. Well, this is where the problem occurred. GEORGE TRIED TO UNNECESSARILY UPSELL ME. He showed up, looked at the unit, agreed it was a miswire issue, and then said he would need an additional $225+ to fix it (that's in *addition* to the service call fee). I thanked him, told him to put it back the way he found it, and I paid him for the service call. I went up into the attic, moved *one* wire (from Gh to Gc, which was one screw terminal over, maybe a 1/4-inch away), and all aspects of the system functioned properly. The time it took me, including moving the wire, testing the system, and putting away my screwdriver and ladder, was 20 minutes. I am *not* an HVAC professional and the fix was that easy. Summit's been licensed as a sole ownership C20 contractor with the CSLB since 2008, so I have to assume they knew what they were doing. read more

After our first quote of $2800 to install a new electrical box by a different contracto, Matt and Ryan were in and out within an hour with all our problems fixed and no new box needed. They could have hit us with the same fees, but we're more than honest with what we really needed at less than $150. Summit will be our go to for any future air or electrical needs. Thanks so much!!!! read more

The technician Mike was so incredibly rude. He yelled at me and my tenant over an issue that had taken over a month for them to complete.

During an OC heat wave, our a/c stopped working. We called multiple repair companies and they all said it would be days or weeks before they could do an inspection. Meanwhile, we were melting inside our house. Enter George. He called us back to say he could swing by that same night and he was courteous, competent and thorough. (Plus has a great sense of humor.) Although he didn't have the part we needed, he was able to make a temporary part to get the a/c working again. Super impressive and he definitely went out of his way to help. He will switch out the temp part with the new part once it arrives, but for now we're set! George has been in the business for more than 20 years and definitely knows what he's doing. read more

My 3rd call to George. Not as successful as the others. Was here from 7:30pm until Midnight. Then had to come out the next day after from 7:30 to 10pm. Yes, his time was extraordinary...but he could not diagnosis the problem or offer an acceptable solution. I called an A.C. company 2 days later, and within 5 minutes, the issue was uncovered and decent solution offered. read more

My heater gave out before Christmas, so I called Summit Air our, because of the excellent service I had with them years prior. George was very thorough in his troubleshooting and went above the call of duty to resolve the issue. I highly recommend. read more

This guy is absolutely fantastic. Knowledgeable, educated, very experienced, informative, and interested in doing the right thing rather than cutting corners. He definitely knows his trade, and it shows in the quality of the work that was done. Highly recommended, and will be referring others in the complex to him. read more

It has been since the winter of 2014 and I still think of the experience I had with the service of "Summit Air Heating & Cooling". However, I did get a partial refund with his deduction of $20.00 for his cost of travel. The fireplace is gas with fake logs and it was old. The knob was so hard to turn and the gas just would not turn on. I paid for the visit, He was poking around and checking all the parts and the solution presented was to buy a new one. I was told that it would be very difficult to find those kinds of parts and he would have to take the whole thing apart and take it with him and then said something else could be found wrong, too. He left and I was disappointed. Later, a referral came from the neighborhood web site www.nextdoor.com and the man asked me to take a photo on my mobile phone and he set an appointment. He brought the parts he needed and fixed the old thing. I would refer, "thefireplacetechnician@gmail.com (714) 927-6031 read more

1) You quoted me $400 to re-work the 4 year old pump and flush the air. The latter was not needed. 60 seconds of work we could have tested it to see that everything was fine. You either misdiagnosed on purpose or have no idea what you are doing with hydronic systems. I fixed in 1 minute after my own research which is infuriating that you tried to take advantage of me. 2) Re-worked. Yep. Took maybe 60 seconds as I have already said. 3) You do not need to open the hydronic system to unjam or service it. How do you not know this? I encourage you to click the youtube link I provided. 4) Irrelevant. My building was re-piped 9 months prior to your arrival. 5) I inspected it further. It was not damaged at all. You spotted some marks on the wall behind the motor and said the motor must be damaged. Again, misdiagnosis - it is in great shape actually. Look at it from my point of view. Paid a "professional" $80 to take a look at my unit for 30 minutes. Had they truly been a professional they would have simply un-jammed the motor in 60 seconds and been on their way. Instead this professional quotes me over $400 for an unnecessary flush and says maybe more if the motor needs replaced. I discover this when I fixed it myself. Why would you quote for a flush when we should be first testing to see if the 60 seconds of maintenance worked? It is as if you quoted me to replace my car engine when all it needed was some fuel. You either do not know what you are doing with hyronics or you are dishonest. If you had some integrity, you would have refunded the $80 for your misdiagnosis. read more

We have gone through 2 AC companies. George is very honest... yes, he is busy, but he takes his time to listen and assess the problem. He takes his time to educate and explain his findings. He is practical... He is helpful. The honesty is very important in this type of business. We don't know anything about AC, pipes, ducts, air vents, etc etc... This guy knows his stuff and he is NOT trying to rob you... If you want an honest business to do the job, this is the company!!! read more

I just finished working with George Valerio, of Summit Air Heating & Cooling. George arrived promptly at the scheduled time. He was very Cheerful and professional. My furnace was not working. He found the problem, burnt circuit board. Was able to get the part next business day. Installed and found second problem. Igniter was burned out as well. Next day Replaced and all working well. Mr. Valerio is A very nice gentleman and you will enjoy working with him. Jinsen Michael Davis read more

Can't speak highly enough of Summit Air Heating. It took me a while to figure out that although my thermostat was switching on there was no warm air coming out of the vents. After almost 5 hours of troubleshooting and identifying that my furnace was perfectly fine, it was narrowed down to my Nest thermostat being faulty. Ahhhhhhhhhh. Frustrating. Simple fix. Inexpensive. Thoroughly recommend using them. read more

I cannot say enough to describe how satisfied I'm with George's service. I called on Saturday, right after the Thanksgiving for an issue with one of the gas furnaces at my place. He explained on the phone possible charges, his current schedule and how the assessment charge can be applied to a small job. He kept me updated with text messages for his arrival time. Once he arrived, he quickly identified the issue and fixed. It was covered with the assessment fee. He also gave a very detailed write up with steps taken and recommendation. Beyond his technical knowledge, what I am really happy with is his attitude and honesty. It was a pleasure to receive service from him. Very highly recommended. read more

George came over to look at my AC issue where we had the breaker tripping multiple times a day. George is extremely thorough and honest when it comes to describing the issue and the potential solutions. He was completely upfront and transparent every step of the way. Ultimately George was able to get our AC back up in working shape, even though he acknowledged that our system still has some unresolved issues. read more

Owner/Operator George Valerio does a great job. His excellent customer service began before he even came out to do the job: he promptly returned phone calls, was realistic about his availability (he is quite busy in the summer), and showed up at the agreed upon time. George clearly communicated the fees for his services before he arrived so there were no surprises. He did a quick diagnosis of the system and took the time to discuss the options for the necessary repair. In this case, our A/C unit was low on freon, but before simply beginning to add more, George ran pressure checks on the compressor to verify that there was not a larger mechanical problem. Following the initial diagnostic work, George clearly walked through his plan of attack; detailing each element of the process and his associated fee (again; no surprises). Once he got started with the agreed-upon plan, he was methodical and thorough. He identified the suspected leak point and then performed multiple checks on the compressor suction and discharge pressures to correlated them with the air temperatures at the vents inside the house and that at the return to the air handler. He carefully recharged freon to the unit checking and re-checking all of the various readings along the way. Did I mention that he finished all of this work at 8:30 PM? It is an important point because at no time did I feel that George was in a rush to leave. His work involves precision and attention to detail, and he patiently worked until the repair was complete and his customer was satisfied (not to mention cooler!). He wouldn't even accept a cold drink until he had "earned it." If you need some HVAC work in Aliso Viejo or the surrounding area, you will be in good hands with Summit Air. George is licensed, bonded and insured. While those qualifications are likely par for the course, the quality of his work speaks for itself. read more

I called a number of companies about my thermostat resetting/rebooting and the other companies could only make appointments about two weeks out. I called George from Summit Air and before talking about booking an appointment, he actually took some time to walk me through some easy things I could do over the phone to see if that would fix the issue. I actually did find something wrong as a result of that phone conversation which was great. The original problem still remained though so he said he would swing by even though it was 7pm on a Friday night (same day service!). When he came, he methodically went through the various issues in a pretty efficient way and narrowed it down to a clogged evaporator coil. During his troubleshooting he actually pointed out a duct problem that another contractor made and helped me to fix it. He was very open about his pricing and let me know what the price was throughout the troubleshooting. His invoice was also very detailed and not just a two word scribble. My only one very slightly negative comment (just to be fair) is that he is really friendly and talks a lot (which is good), but perhaps the work could have been performed a little faster at times so that the troubleshooting call would be cheaper. With that said though, I still think I got a good deal that avoided "hunting and pecking" to determine the issue. Great job! read more

George is a very honest and true professional. Our AC went out on a hot Saturday, and George was a life saver! He is really passionate about his work and is extremely knowledgeable. He approached our AC issue like a good scientist would approach a tough experiment....he was very thorough and was able to fix our AC issue. Very knowledgeable....honest....highly recommend! read more

George from Summit Air Heating & Cooling is awesome. He deserves 10 stars. Our heater was not working after we came home from vacations, when Aliso Viejo is super cold during December-January 2015. He responds right away when I call him. George examines the ac/heater thoroughly & he knows exactly what was going on. George is not a salesman! He's not trying to sell you anything unless it's really major/important. He is local, very honest, professional & very understanding inside and out about this matter. He will educate you and explains what you can do in the future (maintenance, etc). His work/craftsmanship is very meticulous; he won't go home until everything is perfect! This is dedication. Plus my kids love him because he's fun! We trust him 100% with our heater/ac. - Donny & Amelia read more

I was in a bind with a very hot day and family just arrived for a visit. I called Summit and spoke with George, he tried to help me over the phone after explaining the issue. When that did not work I called back and he fit me in even though it was close to closing time, which I greatly appreciated. He explained the basic charges for coming out to diagnose the problem so no surprise later. He came out and spent some time in my very hot attic to diagnose the problem. After figuring out that it was my thermostat he offered solutions, was honest about options and installed and programmed my new thermostat. George is a man with integrity and I would definitely recommend him to anyone who needs AC or heating work done. read more

George is incredible! So thorough and goes above and beyond. He researched the exact system we own and found all of the exact parts it was made with and worked directly with the manufacturing brand of the unit. I cannot say enough great things, he also got our AC working during the terrible heat wave this year. We can't thank him enough for his hard work, honesty and integrity! read more

Outstanding and very personable service from George, and real skill and innovation in solving our AC problems. All this at the end of a long working day and he still took the time to come over because we have a little baby who was not sleeping well in a hot house. AC fixed, the house is chilly, and the baby is sound asleep. This guy is such a superhero he should wear a cape. read more

Thanks George! This guy is outstanding. Use his services. Seriously. Call him. He is knowledgeable, experienced, and answers his phone! I found George to be a man with business integrity and superb work ethic. He found the problem, was upfront about the cost, and went over and above in providing professional service. Highly recommended! read more

George is a class act and very professional. He communicates very well and does a fabulous job describing in laymen's terms, what is going on. I would highly recommend!!! read more

George is an amazing technician. Caring and careful, he always accomplishes his jobs in a timely manner. One of the few that can be depended on! read more

George fixed my AC unit in the summer so when the heat went out I called George and the next day, Dec 31st 4pm George is diagnosing my heater issue. Well, he finds the cause which is a 3 hr job to replace the controller in the attic. George informs me he has a New Years party at 8pm that night so he gets started right away. Well, heater works at 7:30 and George made his New Years party that night and celebrated in style. Thanks George for keeping us warm!! read more

Needed someone to come out and take a look at a/c unit and do general inspection. Left a message but never got a call back. Disappointing because they had such good reviews on Yelp. read more

George came to our rescue the first day our AC went out. He is very responsive, responsible and super knowledgeable! It is refreshing to find someone who you can trust to do the right thing and fix the problems rather than over charge you. We discovered George last year when we had a problem with our heating unit and we didn't hesitate to call him this week when our AC was not working. We truly appreciate his work ethic and truly recommend him! read more

George is an amazing guy! He spent countless hours at our place trying to fix our (extremely messed up) AC unit and setup so we didn't have to shell out thousands for a new one. The previous owner messed around with everything so much that George said it was the second worst situation he has seen in his 20 years. In the end he got it working! We are eternally grateful for this hard-working, honest, and reliable man. He could have easily said "forget it, it's too messed up to fix, just get a new one", but he chose to work his magic instead. We recommend him 1,000% read more

George has got some serious skills. He was able to repair my 40 year old a/c unit without any trouble. The unit is working better than ever. I would highly recommend George if you require any HVAC repairs. read more

WOW - George is absolutely the best!! Called him with an ac issue and he came the same day to help our family. He's accurate and a very nice person to work with! I would HIGHLY RECOMMEND him to anyone and will refer anyone I meet to him. Thanks George! read more

George located my a/c issue within 10 minutes. He was honest and very informative. I would definitely recommend him for any HVAC issues.

I am so impressed with the exemplary service I received from George at Summit Heating & Air. He was able to diagnose my heating issue and resolve the problem on the spot. I had someone else look at my heater and he quoted me 3 x what George did. Not to mention I'm getting a brand new digital thermostat in the price! I'm so impressed and appreciative of the service I received today. Thanks George!! read more

Thank you George for taking extra time out of your day to check in on my elderly parents' air conditioning unit, especially during such a crazy heat wave in March!!! We appreciate your kind and professional courtesy. We are thankful that there is someone like you that has such integrity with your service and pricing. We hope to be able to utilize your services if ever a need arises in the future. read more

George is proficient, skillful, and professional. He is passionate about what he does and it shows-EVERY TIME! He is the only person I would recommend for any HVAC repairs or problems. read more

Absolutely the best. We called this gentleman George who responded by telephone promptly and came over & fixed our AC unit (it needed a capacitor to be replaced), and he explained everything throughout the entire process. His pricing was very good & we found him to be honest & professional. Thank you, George! read more

It was my first time using George and Summit Air Heating and Cooling. I got his number from Yelp. The reviews are exactly what they say he is: thorough, honest and he will go out of his way to explain and show you what is wrong and needs to be fixed on your unit. He came 40 minutes after I called him...he was all booked up for tomorrow so he came over after normal work hours and got the job done. His number did change...its now 949-205-8845. I live in Aliso but he services the surrounding cities. read more

Prompt Honest Thorough Trustworthy Quality Work Respectful Kind Fair George was awesome. He weighed all options and kept us in the know the whole way through. He was extremely fair with his pricing. George went out of his way to get us a new motor for our dinosaur rusty AC unit when we thought all of the parts were as extinct as our unit! He saved our fan that was rusted onto the old motor which saved us a ton of money. Thanks George! If and when issues arise with our HVAC we will be calling you! read more

George is awesome. I called him based on these yelp reviews and he delivered. Although my particular issue is not his core business, he was VERY helpful in pointing me in the right direction, and donating time from his busy schedule at no charge to help me on the phone. George is as great as advertised! read more

If you're looking for a "honest expert" to work on your air conditioner or heating system look no further ...George the owner and operator of Summit Air Hearing & Cooling is your guy. George arrived at my home at the promised time to assess why my heater stopped working. I really appreciated the fact that George told me that he "hates" replacing costly parts and with that he spent time to meticulously check the computer board, igniter, etc, before determining a small motor fan was not creating enough vacuum necessary for a switch to ignite the gas burners. George carefully removed the motor and told me he would call me the next day with a cost estimate for the part. Indeed, George called me the next day as promised, however he told me that when he examined the motor on his workbench a small piece of fiberglass fell out. George told me the cone shaped piece of fiberglass was more than likely blocking the duct inside the motor explaining why his test meter was not detecting the proper amount of vacuum. George said before he orders an expensive motor for my furnace he wanted to reinstall the motor. Later that day George arrived at my home to reinstall the motor fan and sure enough my heater clicked on and it worked perfectly ...saving me a lot of money!!! George could have easily run up my repair bill by ordering a new motor fan, but he doesn't roll that way ...he's an honest technician. I have no hesitation to call George in the future and I can unequivocally recommend him to anyone having heating or cooling problems. read more
