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.

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.

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!

Not only did they completely fail to show up, but there was also absolutely no heads-up, no follow-up text, and zero respect for my time.

Save yourself the headache and call someone else.

I chose Air Max because of past Yelp Reviews that were largely positive and also because of their…read moreaffiliation with Lowe's who offered interest free financing for two years. The Air Max staff and workers were courteous and responsive to my questions and concerns. However, the quality of work was somewhat disappointing and I give them an average rating. During our in home estimate, the Air Max rep explained to us in detail about the equipment that would be replaced and the amount of work involved. One of the items he included in the contract was a "flat roof pad" on which the several hundred pound HVAC unit would be sitting on. After the installation of the unit, I checked the work and saw that the workers did not install the "flat roof pad" per the contract. Instead, they placed two 2"x 6" boards (which they found on my property and used without my permission) under the front end of the unit to level the HVAC on the slightly pitched roof. The boards were positioned perpendicular to the direction of rainwater drainage. At the back end of the unit, the metal framed HVAC sat on bare asphalt roofing. Thus, this several hundred pound unit was installed on my roof with only two points of contact to support its weight and one of these points consisted of a three foot long, 1/8 inch wide edge of metal frame. I showed a photo of this to a licensed roof contractor and he said that was not an ideal situation. Earthquakes, strong winds, and vibration from the HVAC could cause movement and damage the asphalt roofing. I called Air Max and the workers returned a week later to remedy the install. They installed 2"x4" boards (they brought their own wood this time) and positioned them parallel to the flow of drainage and added vibration dampeners underneath the front end of the HVAC. They secured the HVAC to the 2"x4"s with steel straps but left sharp pieces of steel strap cuttings on the roof. Since the HVAC was now raised about 1 1/2" with the 2"x 4" boards underneath it, I checked the main duct connecting the HVAC to the attic opening and saw a 1/2" gap between the duct and the attic opening, a large enough gap for small critters to access. I didn't want to deal with Air Max anymore so I just sealed the gap with expanding insulating foam. The representatives and workers from Air Max were courteous and professional and the Lennox HVAC they installed delivers strong cold / heated air. Air Max also installed new ducts and registers to two of our bathrooms without charge which I appreciated. If you hire them, make sure you check their work! Ensure that their work is done to your satisfaction, that they clean up after themselves, and perform the job according to the contract.

Though we had our entire roof replaced one year ago, and our HVAC roof conduits were also replaced, a pesky leak reappeared coming down one of our events in the back room. We thought this had been resolved with all of the new materials on the roof. Apparently, the sun decided to degrade some of the seals over the summer! My gut instinct was to contact the roofing company, Specialist Roofing & Repair, and have them assess the situation. I also called Go Air. The roofing company fairly quickly determined that it was a breach in the seal attached to the HVAC conduit. Offir, from Go Air, kindly agreed and took care of the situation promptly! More recently (mid-November, 2025), we had a more significant leak come down through the return vent inside of the house. Long story short, Offir and his team came out once the rain subsided and thoroughly took care of the situation (some new cracks in old sealant on the HVAC junction box). Ever since my first interaction with the entire Go Air team back in 2019, they have been friendly, attentive, and professional! I continue to highly recommend them!
