    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 am so happy we found Robert Hall and Sons!…read more We had a very old, but still working, HVAC system. This summer, after going through our warranty company for a check-up, the technician ended up blowing our compressor. We then spent four visits trying to get the AC working again. It never did. Unfortunately, we realized too late that we had been completely scammed. While trying to get it fixed in August, we were also ghosted by another company right in the middle of a heatwave. Needless to say, I was stressed and overwhelmed. At that point, we decided to replace the entire system because we no longer trusted putting more money into repairs. That is when we called Robert Hall and Sons. Mike came out for an estimate, and right away, we felt like we were in good hands. He patiently answered all of our questions and, true to his word, we had a written estimate a few hours later. The estimate we received was beyond reasonable. After we submitted the signed contract, we were scheduled for installation about a week out. A few days later, I saw that another extended heatwave was in the forecast. After everything we had just gone through, I was not prepared to go through it again without working AC. I explained the situation to Mike, along with our HOA requirements, and he worked with us to make sure everything could be done as quickly, quietly, and efficiently as possible. His crew was amazing. They worked quickly, but thoroughly, and had the entire system installed in under three hours. I honestly could not believe how smoothly everything went. I cannot stress enough how professional Mike has been throughout this entire process. After the nightmare we had just experienced with other companies, it was such a relief to finally deal with someone who was honest, responsive, and did exactly what he said he would do. We now have a new HVAC system, a cool house, and peace of mind. Most importantly, we trust that if anything does go wrong, Robert Hall and Sons will be there and make it right. I would absolutely recommend Robert Hall and Sons. After everything we went through this summer, finding a company we can actually trust means everything.

Jerry diagnosed that it was a low capacitor and freon leak, and that the fan motor was not broken like others have said. Other companies needed me to purchase additional parts to get it fixed but Jerry was able to get my AC working the same day. My HVAC unit was nearing it's end of life so I was also comparing bids on what made the most sense for my condo. Jerry offered to temporarily 'lend' us a new capacitor and pumped freon into my system at no charge while I made the decision whether I wanted just the fix or to replace my system. If I decided to just go with the fix, I would pay for it of course, but if I went with replacing the system, they would just take back their capacitor and reclaim the freon. This was a hugely appreciated gesture. Their HVAC replacement proposal was also very competitive. I ultimately decided to replace the system. The experience was pleasant from beginning to end. Cecilia is the one who helps schedule at the office, very friendly and responsive. Jerry was the technician who helped us diagnose the issue and coordinate the HVAC team. He was friendly, transparent, and always responded quickly to my texts/questions - great communication. The day of, the workers Juan, Victor and Andrew were very professional. Maintained constant communication the whole time, kept me updated on the process and what they were doing. They wore booties inside, protected the floor with tarp, and were just very careful in general. The installation of the unit itself is very professionally done, and they vacuumed everything and cleaned up afterwards. They even explained how to register the units for warranties etc. They were able to remove the old AC and install the whole new system the same day, roughly ~5-6 hours including the crane to get the units on/off the roof of the condo building.

    This might be a long review but here goes. We were very pleased with the quality and…read moreprofessionalism of Manny and his crew back in 2025 We replaced our old 3 ton HVAC that came with the house, to a more modern 4 ton unit.
