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.

It's rare to find a company that combines professionalism with this level of care. Would absolutely recommend them without hesitation.

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.

I had four different companies come out to provide estimates for branching off an existing HVAC…read moresystem to add a new supply vent to an interior room. Robert handled the initial evaluation and was very thorough and professional. Although So Cal Air's estimate was not the cheapest, it was the most comprehensive--including drywall patching and painting--which ultimately made me feel the most comfortable moving forward with them. Other companies either tried to upsell me on a UV lighting system or suggested opening up the entire hallway ceiling, which felt excessive for the scope of work. After accepting the estimate, there was a delay of over two weeks before I was contacted to schedule the service, and I do think communication during that time could have been improved. That said, once they reached out, they were able to schedule the work for the very next day. Victor and his crew were professional and efficient, completing the job in about half a day. They left the space clean, and the overall quality of work met my expectations. Thank you, So Cal Air!

I would highly recommend So Cal Air to anyone looking for honest, thorough HVAC service. This is…read morethe second time I've used them this year, and I couldn't be happier. Last month, they fixed a relay switch that -- with some adjustments -- started working again. The technician noted the part in case the problem returned, rather than just replacing it outright. I was happy they saved me the unnecessary expense AND conveniently noted the part so I could just call if it happened again. Since that first visit went so well, I scheduled my yearly spring maintenance with them. I always have my HVAC serviced every March, but I can say that David (I think it was David) did a noticeably more thorough job than I've experienced in past years. This appointment reinforced what I already thought - that I would certainly reach out to So Cal Air for any HVAC issues I have again. Fingers crossed I don't though!

I highly recommend Lindsey's for anyone who needs heater or AC services! 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! I highly recommend this company and I greatly appreciate Christine, Ryan, and Genesis!

However, I wasn't satisfied with the estimate I received for the repair. I decided to call around for a second opinion and had the pleasure of speaking with Andrew from Air Flow Bros. After explaining my situation, he took the time to clearly break down why a Freon refill might be necessary and what I should be looking out for with my A/C system. He also shared some helpful tips to keep in mind moving forward. What really stood out was his honesty. He actually encouraged me to go with the best price and mentioned that if I needed anything further, he'd be happy to come out and take a closer look. Overall, I really appreciate Andrew taking the time to provide thoughtful guidance over the phone.

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!

I see them at least once a year for regular maintenance, and sometimes more often if any issues come up as my system continues to age. No matter the reason for the visit, they are always prompt, friendly, and fair. One thing I've learned over the years is to schedule maintenance visits ahead of time because they do get busy--understandably so, given how reliable and skilled they are. Their pricing is more than fair, especially considering the high quality of their work. Recently, we were dealing with uneven cooling in different areas of our home. Their team came up with a smart, effective solution by installing dampers, and the difference it made was amazing. They've also suggested a few improvements to help make our system more efficient, and I'll be seeing them again soon to take those next steps. If you're looking for a company you can count on year after year, I can't recommend The Air Conditioning Guy enough. They truly care about their customers and stand by their work.

SERVICE: Andy left a strong positive impression - friendly, professional, approachable, respectable, helpful, informative, knowledgeable, competent, not pushy, and explained everything in a very easy to comprehend manner. He had shoe covers prepared and wore them inside the house, showed up right on schedule, is respectful at all times, left our house cleanly without leaving any trace, explained recommendations & areas of improvement with upfront pricing, offered insightful and useful options to improve our indoor air quality, showed us instrument readings and photos of what he tested/diagnosed, offered a suggestion of what to replace first in the order of importance, and explained technical things so simply that even a 90 year old grandma can easily understand. I really appreciate this about him. Excellent interpersonal relationship & communication skills. I'd say Andy should be the star employee of the YEAR for making his company look so good! I came across Aire Serv of Pasadena at their Taste of Arcadia event last month. From everyone I met that day, to the phone rep who scheduled my appointment, to the technician that came out today - in unison, they left a trustworthy and dependable impression. PRICING: $120 for inspection and cleaning, and additional $150 for out-of-area travel fee (they're based in Arcadia, kind of far to Hacienda Heights). Andy worked on my unit for two hours straight. Discounts available for recommended service/parts if it can be replaced/done during the same visit. Additional discounts available if you're a teacher, first responder, etc. They also have an attractive $20 per month membership option where they perform free annual service plus you receive discounts on parts replacements if needed. A nice peace of mind for an affordable price. OVERALL: Aire Serv of Pasadena left a very positive impression and they would be the first I'd think of calling up shall I need my Heater & A/C serviced, despite being just outside of their usual service zone. I would strongly recommend them to friends of mine who live in the west San Gabriel Valley area. (To the owner: Andy is a keeper and deserves a raise! :) You wouldn't want to ever loose this star employee working for anyone else!)
