Marcel was amazing from start to finish. I called in the morning and he was able to come out by noon the same day, which was a lifesaver during one of the hottest weeks. He was straightforward, honest, and gave no-nonsense recommendation, something I really appreciate. He quickly diagnosed the issue, replaced the capacitor, and suggested adding a compressor saver since our AC unit is nearly 20 years old. No pressure at all, just helpful advice. We decided to go with both and the pricing was very fair. Everything was done efficiently within an hour and our AC is running perfectly again. Highly recommend Marcel if you're looking for someone reliable, honest, and fast! read more

I called a bunch of companies on Yelp with great reviews, and while they were helpful, their quotes were super high. I finally called Marcel. I noticed some mixed reviews, but after working with him, I realized he's just a straight shooter who gets the job done fast because of his expertise. He charges a fair, standard fee and doesn't play games. Marcel came out the next day and gave me a zero-pressure quote. Although my AC and furnace were from 1989 they were still technically 'working,' but I noticed the heater wouldn't always kick on and the AC would struggle. Marcel was honest and said they were fine for now, but you never know when units that old will finally go. I decided to change them now rather than wait for an emergency. Even though I just got the quote, he had an opening and was able to get the AC installed just two days later! A few days after that, I decided to do the furnace too. This is where they really shined: because of how that 1989 Carrier system was built, they had to do almost double the work to modify the setup they had just done for the AC. They came back with no issues, handled all the modifications, and put in the new furnace. Now, everything is running whisper-quiet and they cleaned up perfectly. The crew with Renee, Enrique, and a third helper were super fast and very respectful of my belongings. They answered all my questions. l always prefer to support small 'mom and pop' company instead of a big franchise. You get a personal touch you can't find elsewhere. If you want someone highly knowledgeable who understands your needs without pressuring you for extras, call Marcel. I'd highly recommend them to anyone. read more

We had Marcel and his team replace our ancient A/C and all the duct work.

Date of service was December 2025. I reached out to Marcel to check the carbon dioxide levels on my furnace. I cannot recommend American Air Advance highly enough. From the first phone call to the completion of the job, Marcel demonstrated professionalism, integrity, and skill. The gas company had sent out a "technician" that ended up shutting off the furnace. The first HVAC company I called wanted to charge $1200 for fix a supposed leak. I knew they were corrupt. Thankfully I ran into Marcel at American Air Advance. Marcel was able to schedule me quickly, arrived right on time, was courteous, and got straight to work. What impressed me most was his absolute honesty. After a thorough inspection, Marcel clearly explained the problem, showed me the issue and presented all my options without any pressure. There was no upselling. In a world where it's hard to know who to trust, his transparency was incredibly refreshing. The repair was done correctly and quickly, with minimal disruption. He fixed the issue in less than one hour! The work was spotless, ie no footprints left on carpeting, no garbage left behind, etc. The pricing was fair and exactly as quoted, with no surprise fees. If you're looking for an HVAC company that combines expert knowledge with old-fashioned integrity, look no further. I will be certain to call Marcel for Air Conditioning needs as well. Thank you, Marcel! read more

American Air Advance is a great company. Told me exactly what I needed and didn't try to sell me something I did not need, very very great customer service and by far gave me the best price by far. I highly recommend them and I'm gonna recommend them to all my friends and family. Thank you ( Marcel) great job. read more

The best! Highly recommend American Air Advance. They came and fixed my AC during the heat wave. They're knowledgeable, reliable and affordable. Thank you Marcel! read more

They went out of their way to help me after I got in a pickle from another company removing my old ducts and damaging my old furnace. They got my new system and ducts up and running right before a huge heat wave. Thanks!! (Work was done 2 years ago and I'm slow on reviewing, everything is still going amazing 2 years later) read more

I am beyond thankful to Marcel. I called a dozen places to help me fix my ac and they were all booked out 1-2 weeks. I needed my ac fixed right away because I'm a sensitive sleeper and I haven't slept in days because of the hot weather. Marcel was also booked out for a week but he felt bad for me and said he would call his customers to see if he can squeeze me in same day. I also had a crazy schedule due to picking up my kids and he worked around that. Going above and beyond is an understatement. He replaced a part on the compressor unit and rewired and replaced my thermostat. He faced many new problems along the way but he always managed to quickly troubleshoot the problem. I also appreciate how he didn't pressure sell me to buy a brand new ac system like previous techs. He worked well past 7 pm but was all smiles and cracking jokes. Not just competent but such a nice guy. I'm so thankful I was able to finally sleep last night. Thank you Marcel. You are a godsend and I'm going to recommend you to everyone I know. read more

American Air Advance - New thermostat - Heating & Air Conditioning/HVAC Near Me

First off, Marcel showed up same day and on short notice! We had several companies that were referred to us come by but all of the quotes we received were way higher than what we anticipated for. Marcel showed up and immediately found the problem and with a few tweaks here and there he had my AC back up and running on the hottest weeks of spring! We are so thankful for his honesty. Although he explained this was just a easy fix for the time being, all of the other guys that had came by before him didn't even bother fixing the small issue and leaving it up to us to figure out how to prepare for the bigger problem which is getting an entire new system, eventually! With someone so honest and willing to help us we will definitely call him back when we are ready for the bigger fix. Marcel is very reliable and we recommend his work. We are so glad we were referred to him and will be working with him again in the future!!! read more

Honesty honesty honesty. A different company straight up lied to me about my problem. I called these guys and could tell instantly I wanted them to check my problem. It's a hard decision to call a second company and risk another 100 bucks for a diagnosis but I'm so glad I did. Marcel saved me anywhere from 3 thousand for a band aid to 8000 for a new system, both that I didn't need. I am so happy I called this company. And he showed up with 2 other guys and that made things go even better and more efficient. Thank you Marcel, you deserve all the goodness in the world. read more

Our air conditioner of 25 years decided to stop working this past weekend. We called out the company that had installed it. however they had been bought out by Dial One Sonshine /Avis. They sent a technician out who ran all of the diagnostics and told us that the repairs were going to cost $7000 or we could replace the unit. We decided if we were going to pay $7000 to have something repaired just to have something else breakdown on the unit that we would get a quote for a whole new unit. We let them know that we did want to get a couple of other quotes and so happy we did. Marcel from American air advance showed up same day. We called ran his diagnostic test and told us that we did not need a new unit at this time and he was able to get it running for $550. That was parts and labor. Marcel was so wonderful and very informative. If we ever do decide to get a new unit, we will definitely be getting it through American air advance. Thank you, Marcel for being such a honest and respectable company. read more

Our central AC unit gave out on a particularly hot day. I called American Air Advance at 5pm and Marcel showed up 30 minutes later. Immediately diagnosed the problem, explained the solution and gave some advice for future maintenance. They were so good, I signed up for their twice annual service package. read more

I am so glad to have found Marcel, he is now my go to professional for AC needs! He is an 'old school' professional with decades of experience, offers no gimmicks, but just old fashioned expertise and honest work. He is always knowledgeable, prompt, transparent, and offers very reasonable pricing just like what the many other reviewers are saying. Last year he replaced the AC ducts for my whole house and provided very thorough explanation of the status of the AC system, and the possible need for a mini-split system. And just today after just calling him at 2pm about the AC not cooling well, he came at 3pm, found low freon in the system and a leak, and provided a solution within an hour and now the AC is cooling very well and is ready for the hot weather. Give him a call- and you will likely be highly satisfied! read more

I have an older historic home in Whittier that did not come with central air or insulation, so summers have always been unbearably hot. After researching several contractors, I decided to go with American Air Advance. Marcel stood out from the start--he was straightforward and reasonably priced and not aggressive in trying to work with him. I wanted to go with a small business that didn't have a lot of overhead and pushy salespeople. I found his company listed in a few of the city's building and safety permit HVAC records, which gave me confidence that his work was legit. The installation process went incredibly smoothly. I was surprised by how clean and careful his team was--we didn't even have to leave the house during the work. They managed to complete the entire project in just one week. During the install, I realized that an addition to my house, which gets a lot of sunlight, could benefit from another vent. Marcel agreed to add it without any extra charge, which was awesome of him. After the install, we worked with a HERS tester to verify the system's efficiency. A bit more insulation was recommended, and Marcel also took care of it right away. The whole project was fully permitted, and the city signed off on the install right away. It was a clean, seamless install--you can't even see the lines or any signs that the system wasn't always part of the house. The system itself is fantastic--it uses a slim-line compressor that's compact, quiet, and hidden away, so it doesn't distract from the look of the house. Best of all, it cools the house quickly and evenly, making it comfortable even during the hottest days. One of the things that really stood out was Marcel's honesty. I had been paying him through Zelle in increments because of my daily transfer limit, and I accidentally overpaid. He immediately noticed the mistake and sent the extra money back--no questions asked. That kind of integrity is rare and very much appreciated. Overall, I'm extremely happy with the results and would highly recommend American Air Advance to anyone looking to install or service their HVAC systemc. My house has never been this comfortable! Marcel is honest, efficient, and truly cares about his work and his customers. read more

Can't thank Marcel and his crew enough for the fast, clean, great job they did. One night my AC stopped blowing. Found Services Champs on Yelp and they came out to see if they could fix our ac. They came out and said my main motor and second motor blew and needed to be fixed they advised to replace my whole furnace at that point. Few days later they sent another guy to go over pricing. We were looking at $12k to $15k for a brand new furnace. $2k in just parts to fix the motors. They advised that the whole ducting system needed to be redone as well $9k for that. Called Marce when he got to my house he actually got my AC running again. Told us not only were both my motors NOT broken but we did not need a new furnace. However he did agree that my ducting system needed to be redone. Fixing my ac and the update with everything new less than $7k. AMAZING, HONEST, AND FAIR PRICEING. His guys worked the whole time kept my house clean and were respectful. Definitely recommending Marcel to everyone I know. read more

AC was not blowing any air last night. Called Marcel and he was able to come out this morning. Inspected everything, walked me thru what he was doing and what issue may be and resolved it very quickly. I found him thru reviews here that seem to consistently say that he will be upfront, honest, diligent, professional and prompt. All true from what I could tell. My AC unit is really old so I know I'll eventually need more work on it if not need it to be replaced and I know I'd go directly to him. Highly recommend. I will be recommending him to my friends and family as well! read more

Marcel answered my call and came out to diagnose my heater the same day - in a heavy rainy day. He gave me a reasonable price to replace the vent and relocate the drain pan. Marcel and his crew completed the work the same day, cleaned up thoroughly, and were very respectful throughout the process. Marcel is reliable, punctual, and truly takes pride in his work. I highly recommend him to anyone in need of HVAC services. Thank you. read more

I'll start review No. 2,700 by saying upfront that American Air Advance is absolutely and categorically unrelated to American Airlines, despite the similarity of the two companies' logos. It's also a pretty bleh and unspecific name for an HVAC company, but that's the sole criticism in this review. The star of this review is the man, the myth, the legend himself: Marcel. Marcel is the nicest, friendliest, most efficient, most honest, and most ethical professional you'll ever meet. Our family has been using his services for probably ten years now, and he has never let us down. Just a couple of weeks ago, my parents were having an issue with their heater, and Marcel arrived within an hour in the afternoon even though my dad hadn't made an appointment in advance. Marcel fixed the problem within twenty minutes. We have recommended him to family and friends, both within the Gateway Cities and in the wider San Gabriel Valley, and Marcel's customers are always surprised at how reasonable his rates are. Marcel knows what he's doing, but he's also always checking up afterward to make sure his installation or repair was completely successful. If we have any issues whatsoever, even if it's something as insignificant as a slight rattle or an unusual noise, he'll come back out and fix the problem. I can't count the number of things in my parents' house he has installed and/or fixed. He's so good at his job, in fact, that the the inside joke in our family is that when anything breaks, even if it's outside of his area of expertise, we should just call Marcel. And the truth is, he would probably show up just to try to fix it--and he might just succeed! If you're in the area and need any sort of heating or cooling repair or installation--including new construction--call Marcel. Unlike many other contractors, he always arrives on time and is very responsive. He's also very honest. He will tell if you if a particular time frame won't work, and he doesn't take on tasks that he can't complete. On more than one occasion, he has recommended to my parents a different course of action that was cheaper for them but meant less work and/or profit for him. In short, he always has the customer's best interest at heart, not his own. I cannot say enough about this fine gentleman. read more

When my AC stopped working--neither blowing hot nor cold air--and the condenser refused to turn on, I was worried I'd be facing a hefty repair bill. I got quotes from a few companies, and most pushed me to replace my entire furnace at a steep cost. Then Marcel came to the rescue! He quickly diagnosed the issue, explained everything honestly, and offered a fair price for the fix. Not only was he professional and friendly, but he worked efficiently and had my AC running like new in no time. I'm beyond pleased with his service and highly recommend him! read more

American Air Advance - Furnace - Heating & Air Conditioning/HVAC Near Me

Exceptional service! We called for an AC repair. Marcel answered and was able to respond in 2 hours. He is very knowledgeable and was able to diagnose the problem right away. One of the parts was no longer functioning and needed to be replaced. He went right outo his business van and grabbed a brand new part. He also recommended an additional part for better maintenance at a very reasonable price. My husband and I really appreciated his honesty and professionalism. We plan to call him back before winter for our heater maintenance. read more

Same day service! Called at around 8:00 am and was able to get a service appointment that afternoon. Marcel arrived on time, was friendly and knowledgeable, and really went above and beyond to get my AC up and running again in no time.

Highly recommend the work Al and Marcel did for me. I have an older home a little over 1,000 sqft that has no ventilation system and no attic access. Marcel suggested a mini split system install which ended up working perfectly for my needs. They came out and looked over my home and gave me a few options to work with. They were super friendly and helpful and not at all pushy. They even suggest seeking out competitors to ensure I was getting the best price for what I was looking for. With summer coming i was sure scheduling would be busy but they were able to squeeze me In early and work around my schedule to get the work done. His team came in and was highly professional and got the job done fast and neatly. The system works fantastic and I couldn't have wished for a better outcome. Highly recommend using them for your heating and air condition needs. read more

Our AC was blowing warm air so we were cooking in the LA summer heat. I finally had enough one day and decided to find help to service the unit. I called in the morning and Marcel came in the afternoon to take a look. Less than an hour later, our AC's refrigerant was refilled with a mix of leak-stop solution, and our house was cool inside again. Marcel clearly explained the problem and solution, and charged a reasonable price (in my uninformed opinion). I definitely recommend working with American Air Advance. read more

Marcel was excellent at proving detail information on what can be wrong with my ac unit in my condo and gave me options in what he can do to make the ac working properly . Him and his staff are friendly and clean and communicate effectively . read more

We just hired American Air Advance to do a brand new AC installation for our home. They did an amazing job, and were professional all around. Marcel communicated with us the whole time and answered any questions we had. He also has the best prices around! We got quotes from over 10 HVAC companies and no one even came close to American Air's prices. One guy even told us that it seemed too good to be true. But it definitely is true! Go to them for any of your HVAC needs! 5 STARS ALL AROUND FROM START TO FINISH! read more

Marcel came to diagnose my AC that stopped working suddenly over the weekend. He was very thorough at explaining what he found and recommended the best course of action. I felt that he was very honest with me and wasn't pushy to upsell. I decided to upgrade to a Smart thermostat with him and use his company to do maintenance on my central heat and air system. It's important to me to support local mom and pop businesses like Marcel's. Now my AC is running better than it has in years and I have someone to look after it every year. read more

Last year Marcel install a new heat pump HVAC system for us and move it from ground floor to Attic. This was April 2024. Been very happy with his service and professionalism. Come summer and bedrooms are hot, really hot. At first, I reached out to him and letting him know about the heat in the bedrooms, he send his guy and made some adjustments. But still the same. Other areas of the house are good. We just move in to this house which was built on the 50's and does not know better. Later on after some research, found out the wall do not have any insulation and the part where the bedroom are is in direct afternoon sun which I found out that it was hot to touch in the afternoon inside the house during summer time. We are actually in a warm oven. Got Marathon Insulation to do the insulations (another excellent company) for the outside wall. AND!!! solve the problem. The inside temperature of the house is now very manageable. I mentioned this to just mention... not all problem is caused by very obvious reasons. Today, after more than one year of install. I called Marcel for maintenance service and as usual... a wonderful guy with a wonderful service. This review is a long time coming... read more

Just called this place. If you're looking for a free estimate like the listing says, ESTIMATES ARE NOT FREE! Marcel said that diagnostics will cost a fee, so I guess this is the old bait-and-switch. Just an FYI for people looking at places to call for service. read more

Marcel was very prompt in his response and came out the next day to do a thorough inspection! He checked all possibilities of a leak and was quick to offer his help if any new issues came up with socalgas. He was knowledgeable and trustworthy and didn't try to make us fix anything unnecessarily. read more

Its so refreshing to have well experienced technician with great customer service and Honesty!! Not trying to up sale or pressure me into purchasing items not needed. Marcel was upfront and educated me of the possibility why my AC unit was not working. I was surprised that he was able to service my ac unit same day I called. When speaking to him on the phone he mentioned he had a full day but would try to diagnosis my unit today or tomorrow. The soonest other places could come to my home was 2weeks! Greatly appreciate Marcel for coming over same day and was able to fix my issue and now have cool air! Pricing was very reasonable. Definitely keeping him on my contacts for any future repairs read more

Several HVAC companies came out to look at our old, nonfunctioning AC this summer. They mostly said that based on age, we should just replace, rather than repair. One company did a repair but it lasted about 10 days before the unit stopped working again. I read good reviews about American Air Advance, and specifically about Marcel so called him, figuring that he would also tell me to replace. I was very pleasantly surprised when he said he could do a repair, with a different and better part, and if it only lasted a few weeks, and I decided to replace, he would credit what I spent on the repair towards the replacement. Well, it's been about a month now and the AC is still going strong. Feels like it's actually blowing colder than before! When the unit stops working for good, and I know that day is coming, I'll be calling Marcel to come out. And I hope he brings his daughter with him then, too =) read more

My air conditioner stopped blowing cold air. Everything else seemed to work though. Reached out to American Air Advance and a few others, but Marcel was the first to reply. Got a time set up and he was on time. He pretty quickly was able to tell that my condenser unit wasn't properly turning on. He popped the panel off and tested my capacitor, which was good. He then saw that I had a soft starter and tried disconnecting it. Lo and behold, the condenser turned back on. To make sure everything was good, he also temp tested the air vents. I'm overall satisfied and will use American Air Advance if the need arises again. read more

I called American Air Advance, and Marcel picked up immediately. I explained to him that my air conditioner was no longer blowing cold, and the valve behind my condenser often freezes. He shared a few ideas of what could be causing it, and I asked if he could come over later in the day. A few hours later, Marcel arrived and hooked up all of his gauges. He determined that my system needed Freon, and most likely had a very small leak somewhere in the system. When I asked him if the leak could be repaired, he explained the detailed process to locate the leak. He said it would be very expensive and even after the whole process, there is a chance the leak might not be found. He looked at me directly in my eyes and said if he were in my position, he would try something less expensive to keep my system running for a few more years and possibly fix the issue. He recommended using a can of leak stop and filling the system with Freon. I explained to him that I was a teacher, and anything he could do to save me money and keep my system going will be greatly appreciated. After doing what he suggested, the air blowing out of my ducts went from blowing 73 degrees to 54 degrees. The house is cool again, and I'm hoping the can of leak stop may have fixed, or at least slowed down the small leak. Marcel could have easily suggested fixing the leak, or attempted to sell me a new unit, but his honesty and consideration to save me money and keep my system running for a few more years has won me over as a loyal customer. Thank you, Marcel. -Ray (the teacher) read more

We bought a house last year without central A/C and immediately scouted for bids. The thought crossed our mind that the previous owner never installed A/C so maybe it's not so bad in the summer and decided to give it go. Terrible idea. We ended up buying portable unit and camping in our living room for a few nights it was so bad. We knew we needed central A/C before this summer hit. American Air Advance not only had the best pricing out of all bids, Marcel stood out from the rest by being completely transparent and only suggesting what's needed to ensure my house was ready for the heat. He gave us a "good" option and a "better" option. Considering the better option was still cheaper than the next company's bid, we went ahead and splurged. I was a little concerned hoping it's not a "you get what you paid for" situation, but the stellar yelp reviews and Marcel put that thought to rest pretty quickly. At the end of the project I had a new roof mounted central air unit that's insanely quiet (I had to ask them to make sure it was actually working, I couldn't even hear the condenser turn on) and all the work done was clean with high attention to detail. All promises made were kept (including stuff I never asked for but Marcel thought would improve air flow so he threw it in the contract). If you need anything HVAC related, you'd be doing yourself a favor by calling American Air Advance first. read more

I can't recommend Marcell and company enough. I reached out during one of the hottest days this year. My AC wasn't starting. We scheduled an appointment for the next day. I let them know I was available all day if they had a cancellation. Luckily they did. Marcell came out and was very professional and kind. Took a look at the AC and gave me an honest and very reasonable quote. I agreed to the work. Not only was he quick, but he showed me the parts he was replacing and the new ones he was switching them out with. All done before it got too hot too! Do not hesitate to give them a call. Businesses with such professionalism and honesty are hard to come by. read more

We had just purchased a home and the air conditioner was not blowing cold air, and it was going to be a warm weekend. I called Marcel in the morning expecting for him to not have availability, but he immediately said I will be there in 30 mins to diagnose the issue. Once he got here, him and his partner went to work and quickly found the issue, no freon. He explained everything to me and how it works, then we discussed the cost to fix it. He was very reasonable, upfront in what was needed and honest. I was extremely happy with the outcome, and would recommend him to any friends and family. Thank you Marcel, you really helped us out. read more
