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!

Update: To be fair, I did not reach out to the company to discuss my concerns before posting my…read moreinitial review. 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!

Kevin was referred and recommended to me by a community group. And I would recommend him as well!…read more I was looking for someone to repair/replace the AC at my rental unit. He was easy to talk to and work with. After he went to check out what the issue was, we discussed the options available and he got started as soon as he could. His quote was reasonable and fair.

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.

We're sitting inside cool and comfortable on a hot June day, thanks to the incredible team at…read moreDiamond who replaced our old broken 5-ton AC with a smaller, more energy efficient modern Mitsubishi heat pump system. A huge thanks to Anthony and Tiffany for coordinating all the logistics, Anthony in particular was so helpful from start to finish, always available, responded immediately to any question, and just made the whole process incredibly easy. An especially big thanks to our installer Bobby and his crew who did such an exceptional job carefully removing the old system and doing a beautiful install of the new one. They also completely reworked the AC closet, moving the system forward and sealing everything off cleanly, what was once a poorly converted linen closet now has potential for usable space behind it. Whereas the old system sounded like a jet engine taking off, the new Mitsubishi is astonishingly quiet, the condenser is outside our bedroom and you hear literally nothing. It works flawlessly and has been keeping the house perfectly cool through what's shaping up to be a hot summer. This was not an easy install either. The house, like many older homes, is full of quirks and Diamond did an amazing job working around all the pitfalls that come with squeezing a central HVAC system into a house not originally designed for one. Everyone at Diamond was a total pleasure to work with and have in our home. Their pricing was fair and reasonable and the quality of their workmanship is just excellent. If you need any kind of HVAC work done I highly recommend reaching out to Anthony and the Diamond team. Thanks so much guys!

Their team handled the install with real expertise, and everything was up and running couple hours later exactly as promised.

Highly recommend Diamond Air Services for anyone looking for qualified HVAC work.

I dealt with 4 individuals during that whole process, from start to finish, each was kind, thoughtful, friendly and super competent. The crew was here 3 days. My home and yard was treated well and they cleaned up at the end of every day. To add a huge bit of advanced credibility, was my dear friend and pastor of a local SGV church, when I mentioned I was getting mini splits installed the next day, said that he has used Connor Air for the church and school for years and was extremely happy with them. I was doubly assured. One of the moments in the estimation conversation, Jarred, son of the family-owned business, said to me they only offered the best, Mitsubishi, to be used. That was a deal-maker for me. Their pricing was competitive too. Thank you all at Connor!

Although I have used Manny's several times, I continue to be amazed at the truly superb service…read moreprovided by his highly trained technicians. 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. Thus, for anyone in need of AC service, Manny's should definitely be the first business to call.
