    New, super efficient "Nest" thermostat!
    Freddy D.

    Jonathan from "Just one call" just came out to inspect and tune up our A/C unit. Arrived at the designated time A friendly greeting and he went to work. The last folks here, last year, over filled the coolant above 500psi where it should be in the 300 range. Jonathan adjusted the pressure which avoided damaging the compressor. Pretty cool state of the art diagnostic tools pinpoint any problems, when discovered, Jonathan makes the fix. We now have a great new "Nest" thermostat that is amazing. In addition to his professionalism he also scored big, by saying hello to our 19.5 year old dog, she liked him, she can be pretty discerning Anyone that likes dogs is usually a good person! We will be sure to Recommend "Just One Call" to our friends and family

    Free Nest through LADWP!!
    Nigel P.

    Can't say enough positive about using this service. I contacted Just One Call through the LADWP AC Optimization program and have been extremely happy with the results. Greg showed up early and on time, he was very nice and calm, metered even (no pun intended). He worked efficiently and was committed to making my AC work properly which I greatly appreciated, because I like AC. The Nest provided through this program is super clean and easy to use, and I couldn't be happier!! Thanks Greg, thanks Just One Call!

    Woow! What can I say about the service that Just One Call provided to my folks._ First I want to say thank you to ASHOT for being punctual, fast and patient on answering my Dad's questions and checking out the entire system at the house. ASHOT came through the DWP program and was very helpful and had a great attitude. He even helped my Dad to download the NEST app on his phone and thought him how to used it. Thank you ASHOT for helping my parents. I am giving you a five start review for your excellence service.

    bogus claim that there was an electrical short
    Zoey W.

    This company should be called "Just Multiple Calls." Our furnace went out, and our insurance company AHS, sent them. 1st visit -technician was on his cell phone for 20 minutes dealing with a personal car insurance claim. After waiting for him to be done with his phone call, I asked him what the diagnosis was. He said everything was fine and left. (Even though I told him it was the inducer motor because it kept going on and off). 2 days later it went out again, so the insurance company sent JOC back. 2nd visit, it was a technician named Greg. The furnace is in the attic. When he arrived, he tried to say he could not get into the attic. (even though all technicians that came before him, including from his own company, had no issues. Just requires a ladder). After "forcing" him to go to the attic, he got on the phone and was facetiming someone at the company (not speaking english). I asked him what the diagnosis was and he wouldn't say. I explained that we'd been through this already, and I couldn't have him leave without a diagnosis to report to the insurance company. It was simple, the inducer motor and it needed to be replaced). He tried to leave without providing any info, an invoice or diagnosis. I had to chase him to his van. He was on the phone the whole time with someone at the company. Since was taking pictures of his van (as evidence he was there), he finally wrote the diagnosis and said he'd come back to fix it. They never called. After multiple follow ups, they made a bogus claim and said it was a problem with electrical. They knew this would trigger another appointment, but I had to go through the process with the insurance company. The electric company came, and said there was no issue with the electrical and nothing was tripped. They were confused as to why Just One Call made that claim. They also found the furnace was unplugged and a nail had been jammed into the inducer motor. Shady. Once the electric company reported their finding to the insurance company, it was cleared for Just One Call to come back and fix the furnace. Surprise surprise, after several calls, the job got transferred to Global HVAC because Just One Call denied it. (I'm glad they did because Global HVAC ended up being awesome, but Just One Call is shady). I think they make money on bogus visits through the insurance company. They just keep making appointment after appointment. I guess they get paid by visit. I'm not sure if JOC is paying marketing companies for these fake 4 star reviews, but they do not know how to fix furnaces. Global HVAC ended up replacing the inducer motor in under an hour, while these clowns at Just One Call made appointment after appointment. Don't call these guys at all they are frauds

    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!

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!

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!

I hope others will still consider giving them a chance, and if issues arise, I'd recommend reaching out directly to discuss possible resolution.
