He took the time to clearly explain what he and his team would be doing, which made me feel confident moving forward.

On installation day, his team was professional, easy to work with, and worked efficiently to get the job done in a timely manner. After everything was completed, his team walked me through what was done on the roof and made sure I understood the work. Overall, their confidence, professionalism, and clear communication made this a smooth and stress-free experience. Thank you for the excellent service!

The EZ Breeze team was incredibly responsive, communicative, and easy to work with. You can immediately tell they're passionate about what they do--they take pride in their work and genuinely care about their customers. Everyone I interacted with was friendly, honest, and transparent, which made the whole experience stress-free. They went above and beyond to make sure everything was handled properly. It's rare to find a company that combines professionalism with this level of care. Would absolutely recommend them without hesitation.

Quan I think that is his name, answered quick, and gave me his pricing which was very competitive. He also showed up in two hours, he pinpointed where the possible leak was coming from, at the condenser showing a darker spot so I leaned something new, he added in a sealant and charge for that was reasonable. He was done within an hour, even showed me how much refrigerant was injected. Highly recommend.

My AC recently stopped blowing cold air right before the heat of the summer here in the SGV, so I…read moreknew I had to get it fixed before things got to be too hot! This was my first time having to get it serviced so I had no idea where to look. Enter the old reliable Yelp whose reviewers led me to Quan AC Services! It was easy to get in touch with Quan, who got me set up with an appointment within the next 2 days. He was communicative, professional, and friendly, and worked with my schedule to make sure that I could be helped in a timely manner. During my service call, Quan was the consummate professional and took the time to ask me questions and explain the steps in the process to troubleshoot the issues with my AC. He even took off his shoes before entering my home! After just a couple of minutes, he had identified the issue after conducting some tests and I was fortunate enough that he had a replacement part available in his truck. I paid a very reasonable sum for the service call/diagnostic, his time, and the replacement part and was pleasantly surprised to walk away from the experience without an exorbitant bill and/or days and weeks of waiting. Weeks later, and my AC is blowing nice and cold as it should be. Thanks again, Quan! 2 thumbs up!

I woke up one Sunday morning to a nightmare scenario: something in my attic was leaking directly…read moreinto my kitchen. I assumed it was the AC unit sitting right above it, so I contacted Pioneers in a mild panic. They quickly put me in touch with Tomer, who showed up that same afternoon to take a look. From the moment he arrived, Tomer was calm, kind, and completely professional, which is exactly what you want when you're stressed about water dripping through your ceiling. He diagnosed the problem efficiently: our AC drip pan had overflowed due to a clogged drain pipe. He walked us through everything as he went, answering every question we threw at him without making us feel like we were slowing him down. He needed a couple of additional parts he didn't have on hand, so he promised to return Monday morning to finish the job. And he did, right on time. When yet another part turned out to be needed mid-repair, he didn't reschedule or leave us hanging. He went out, got it himself, and came straight back to finish what he started. No drama, no delays. While he was up in the attic, he also flagged some rat droppings and other pest concerns. But not in a pushy, upsell-y way, but just as a heads-up. "Here's what I'm seeing, I can get you a quote if you want." Refreshingly straightforward. Tomer turned a stressful Sunday emergency into a resolved problem by Monday afternoon. Thanks Pioneers H&A!

After the review was posted, the owner, Motti, contacted me to better understand what happened and to address the situation. He offered to refund the service fee because I was dissatisfied with the experience. While they were not the ones to fix my heater, I do appreciate the effort to follow up and their apparent commitment to customer satisfaction. I hope others will still consider giving them a chance, and if issues arise, I'd recommend reaching out directly to discuss possible resolution.

We recently had our HVAC ductwork replaced in our 1920's house and couldn't be happier with the…read moreresults. Juan had a complicated project on his hands since all of our ductwork is contained underneath the house, with very little clearance. Not only did the old ducts deteriorate over time, but many areas were also no longer up to code. From start to finish, Juan was professional, punctual, and incredibly knowledgeable. The installation was smooth, and he kept everything clean and organized throughout the process. Since the new ductwork was installed, we've noticed a huge improvement in airflow and indoor comfort--each room now cools evenly, and the system runs more efficiently. What sets Juan apart is how much pride he has in his work, and it truly reflects in the final results. He basically remapped the entire ductwork to maximize the potential of our heating/cooling system. I would highly recommend his services to anyone needing HVAC work. We have recommended Juan already to several of our friends and family. Quality workmanship and excellent customer care!

TLDR: my experience with this company has been an absolute nightmare and I would give negative…read morestars if I could. Kevin took $4500 from us, didnt buy any material for the project and didnt do any work. He promised us a refund on text, and then stopped responding and never gave back our money. The most unprofessional and dishonest person I've ever met. On August 25, 2025, my partner and I paid Kevin Lee from let's chill HVAC a 60% deposit for HVAC installation. The invoice did NOT state that deposits were nonrefundable. We paid five days in advance of the agreed start date because he said he needed money to pick up the equipment. By that date, after following up to confirm, he finally responded -- hours later -- that he hadn't picked up any equipment all week and now the warehouse is close for Labor Day weekend. Instead, he tried to upsell us on a different unit than what we originally agreed on, then admitted he didn't have a truck to transport equipment and couldn't perform the job on time regardless. At that point, we asked for a refund to hire a more reliable company. Mind you, we've been without AC for an entire week during the hottest months of august. During this time, he ignored multiple calls and texts from us, but I confirmed through my own Yelp account that he continued responding to new customer inquiries. This shows he was selectively avoiding communication with us. Finally, after 12+ hours, he said he would return only $3,500 of the $4,500 deposit and said that the law allows him to wait 30 days. That deadline has passed, and I have not received the refund despite his written promise. No material was ordered and no work was done and he wants to keep thousands of dollars from us. After talking to other contractors and researching online, under California law (Bus. & Prof. Code §7159.5), contractors are prohibited from requesting or accepting more than 10% of the contract price or $1,000 (whichever is less) as a down payment. So technically, our down payment should've been $750. In this case, the 60% deposit was well above the legal limit so I will report this accordingly. This experience was frustrating and Costly. HVAC is a saturated field so please speak to multiple people and go with someone that's trustworthy. Also, you should always verify a contractor's license status with the California Contractors State License Board (CSLB) before paying any money because it's illegal to do HVAC work in California without a license.

Brand new AC system- absolutely HIGHLY recommended company!…read more I went with Connor AC based on a friend's recommendation (used for their AC system) and because they were local to me and easily accessible. Consult and walk thru was done by Jarred- absolutely professional in all mannerisms, dress, prompt, follow up, ...and easy on the eyes as well. I put the job off for a year bc it was just too much - cost too much and too much invasive work. I have a separate upstairs and downstairs AC units and the downstairs one literally breaks down every summer, electric bills skyrocket, house never gets cool, different guys adding all kinds of freon and tinkering around trying to get our house to cool down in 100deg Cali summers! Finally my downstairs one just broke down 80-85deg inside the house on a 100deg day. I called back Connor and asked them to update the proposal (post- Trump and tariffs) and was determined to make it work this time. My job entailed taking out my 2 old outdated builder's grade 10SEER fans in the backyard, then having the concrete that was custom built underneath them re-done. Then a whole new 16SEER Lennox top of the line system would be installed. And then it rained. Literally never rains in Cali but all 4 days of my proposed job showed forecasted rain!! Day 1- John and his helper Sebastian came to start the job. Work hours were about 8-2ish. They took time to prep and lay out floor covers to protect my carpet and tiles. Then they removed my 2 furnaces inside the attic thru a tiny 2x2 trap door in my closet! John and Sebastian work quietly and efficiently and really surprisingly make the most of their time! 4 days later I had 2 brand new AC units, got the heat working in these colder winter temps, John even re-routed my ducts to improve airflow and basically cleaned up my attic - which now resembles a fully functional clubhouse! Such clean and detailed work! I'm so happy I went with Connor AC and so impressed with the work done by John and Sebastian. They're quiet and clean and so professional. John just seems like such the can-do guy - so highly recommended and Connor AC is so lucky to have him. Please don't ever retire John, in case I ever need any follow up AC work!

In this regard, Jesus came out to look at our AC system yesterday, which has been working only intermittently. Following a very thorough diagnostic assessment of the overall unit, Jesus suggested that we hold off installing any new parts at this time, as the system is somewhat old and doesn't provide any specifics concerning what needs to be replaced. Indeed, I appreciated Jesus's honest and straightforward assessment, as opposed to relying on guesswork to resolve the problem. At this point, I expect that we will likely be replacing our aging unit sometime this year....and, without a doubt, Manny's will be the company I call to do the job. Along with providing prompt and excellent service, the three technicians I've met from his company have all been very professional, courteous, and personable.

They came to us highly…read morerecommended by our friend who had used them in the past and boy are we happy with the recommendation! They are professional and very experienced. They were able to fix our heater problem when our prior HVAC guy could not. And they fixed the problem with less costs than what we paid our other/prior HVAC guy. Further, because our prior HVAC technician could not fix our heater problem after 3 visits, we were recommended to replace the whole HVAC unit and the ducks. However, when Lindsey's came, they told us that we would not need to replace our HVAC system or the ducks because, after much investigation, they found that it was just a roller switch that needed to be replace and all they needed to do was to try and find that brand of switch then we should be ok. And they did it! Not only are they very experienced with the various types of heaters and AC systems, most importantly of all, this is a vey honest company! Because we had to wait for the switch and while waiting the temperature got cold, Christine made sure that we got a discount for their visits. Also, when our heater had another problem again, they were very patient and they came back right away to check what was wrong. This is a honest and professional company. They are very experienced and most importantly, they won't over-charge you! Their prices for the quality work they do are very reasonable and fair. I especially appreciate Christine who helped us schedule speedy services, made sure that we were not over-charged, and she provided very valuable recommendations and insights regarding the problem of our heater. Our technicians, Ryan and Genesis, were also super great! They were courteous and they explained to me what was going on with our heater with great communications! They assured me that I do not need to worry as if anything goes wrong again, they will come right back. They made me feel at ease with the situation and I greatly appreciate that they were able to fix our heater without us needing to switch out our whole HVAC system! What a lifesaver!
