From the initial consultation through installation, Menooa and his team were professional, knowledgeable, and easy to work with. They also enlarged one of my return air vents to meet the higher airflow needs of the new HVAC system. The work required widening the opening in the ceiling and installing a new return grille. The crew handled it neatly and professionally. When they finished, it looked like new. The new system is working great, airflow is noticeably improved, and the entire project was completed fast and as promised. It's not often that a major home improvement project goes this smoothly. I would recommend So Cal Air to anyone looking for HVAC installation or replacement.

We received multiple estimates and Sasoun stood out from the pack. He is on time, honest, provided fair pricing on quality equipment (carrier) and was just wonderful from estimate to install completion. We have since used CalStar to do repairs on our main home AC. He was quick to get parts and repair before an upcoming heatwave. We always appreciate how prompt and honest he his with any questions or issues we have with our systems. We also used him to install mini split in our garage. Every job we have done with Sasoun we have been very happy with.

Between…read moregetting charged $3,000 every few months for, "topping off freon" (note: my system was installed new in 2018, so I'm not even sure if freon was the refrigerant the system needed), to proposing a $20k install of a new unit while mind was under warranty (twice), to claiming that my warranty was invalid until I set up an email thread with my HVAC company and my repair team to prove that my system was under warranty, to finally claiming that the local supply shop was "out of parts" for 6 months straight (I eventually called the shop, and they confirmed that they haven't been able to get a response from the repair team.). LONG STORY SHORT, I've been through HVAC hell, and finally decided to go with a new, local company with stellar reviews that recognized my system's warranty. Mario came to inspect the system, identified the repairs that needed to be made, was in and out within 2 hours only a day after I requested service, and not even $500 later I'm enjoying a cool, air-conditioned home. Extra points for not trying to upsell me on an entirely new system (lol - happened to me twice since buying my home, neighbors actually warned me about non-local HVAC companies), AND I can safely say that when I DO eventually need a new HVAC system, I'll be going with Manny's. To the team: You are doing things right. Between your expedient responses (even when my only free time is in the evenings), your honest, transparent communication, the fact that your repair man noticed my slippers and threw on booties before coming into the house, and your prices all denote S-Tier service. I couldn't be more pleased, and you've earned a new customer for life. I will be telling all of my neighbors about your company - truly a breath of *fresh air*

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.

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!

Martin from Air Tech provided a very competetive quote for a direct replacement including new curb and ductwork. Martin mentioned that this type of HVAC is more for commercial use, but this suited my needs best. The new Goodman unit and curb Martin's team installed looks so much better than the old unit which was rusting and missing panels. The new drainage pipe was even installed in such a way that there is no unsightly white pvc sitting on the roof (pipe ran through attic with exit at side of house running down along gutter downspout). The old registers and return inside the house were also replaced, plus a Nest Smart thermostat installed. All of which added to the modern look and feel inside our new home. I am impressed by the nearly instantaneous heat or cool air that is produced at the press of a button. Martin was easy to get a hold of and he addressed every concern I had during this upgrade. I am a very satisfied customer.
