My heart stand called another company to fix our Air conditioning. They didn't even look at the unit and said I needed a new compressor. I felt I needed more information. I remembered Robert Hall and Sons and called them. They arrived quickly and I could tell he knew what he was doing because he took the cover off and started troubleshooting....he fixed it!!! They are knowledgeable, have integrity and very professional. Highly recommend! Five stars happy customer here read more

My capacitor went out at night. Called them and got a call back within 5 minutes. They gave me 12-4pm same day. Repair guy showed up at 12:45pm. Even got a text that he was in his way about 15 minutes in advance. He diagnosed the issue quickly and fixed it. Everything was good to go within 30 minutes. The price range came right on the high-end of what ChatGPT told me. Considering that this is LA, that was what I expected. read more

We asked Robert Hall to verify/review an expensive service quote left by another vendor. We found that quote surprising and excessive due to the age of the unit. Joseph was on time, pointed out relatively minor issues that were ignored by the other vendor and performed service that solved the issue at a small fraction of the quote from the first vendor. We are thrilled to have found a new local vendor to service our HVAC system into the future! read more

Our AC condenser stopped working late afternoon Tues. 7/14/'26. I called R. Hall Wed. morning about 8:15am. Service Tech, Joe, took the call and said he was working nearby and would come by right after finishing his service call. He showed up about 20 minutes later. He verified power was off to the unit, opened it up and quickly diagnosed the problem as a failed capacitor. He had the correct replacement in his truck. Condenser up and running by 9am. Wow! Best service call I've ever had. read more

I highly recommend Robert Hall & Sons! From the moment I called, they were responsive and professional. They showed up right away and went straight to the problem without trying to upsell anything we didn't need! Our air was back up and running without any hassle. It's such a relief to find a company that truly cares about their customers. We will definitely be using them again and highly recommend them to anyone needing A.C service. read more

Excellent experience both times I've used Robert Hall A/C. The first visit was for a repair, and the second was for an inspection and minor repair. In both cases they were prompt, polite, and easy to work with (text system kept me informed). They explained the issues clearly, handled things quickly, and were genuinely helpful. Best of all, there was no upselling - just honest, professional service. Highly recommend. read more

I can see why Robert hall and sons has a perfect score on Yelp. We moved into our flipped home two years ago and noticed we were consistently getting more air on one side of the house and almost no air on the other. The lack of even flow of air became even a bigger issue during the winter with the heat in the already dry California weather. Our kids were always getting dry skin and nose bleeds from the ov while the other layered on for warmth. We knew this fix was not going to be cheap bc we had homeowners warranty and insurance who sent our and ac guy. Basically our ac unit wasn't big enough for our house along with other minor issues. We could get a second unit or replace our unit. I researched on Angie's list, home advisor and yelp. I had 4 different people come out. One company that was referred from Angie's list would not give me a break down of the estimate and what it all included. Terrible manners. Another company I found from yelp who had high reviews and over 109 reviews, came out, checked out the ac and the attic but simply said this is a winter job and passed up the job. Another company was from a contractor and it was going to cost a lot AND I wasn't confident that they were going to be hands on and on the job site. So I contacted Robert hall & sons and mike came out to give the estimate. He went to the attic and assessed the situation, was professional and followed up. After a week of back and forth and more questions/ answers, we decided to go with Robert Hall & sons. They (his team of three trucks) showed up two days ago at 7am ready to work. You can sense unison in the way his team worked. No loud music or unnecessary convos...just focused work and communication from his team, In and out in two days. The job was suppose to take 3 days. I also made one change (the location of the second ac unit and talked to mike mid way through the process and he was accommodating about the change. They also cleaned up appropriately inside (no trash outside). I can appreciate who will treat my home with respect and not leave their lunch or drinks behind. It's just as important as the job you were hired to do. NOW I'm sitting here in my cooled room writing this review. Good quality, manners, attitude. read more

After having several bids for a new HVAC system including new ducting, we went with Robert Hall and Sons. They were the most transparent re their bid and they are a joy to work with. The installation of our system was hassle free. It was so great that I hired them to replace two air conditioners for a property I help manage. They are responsive, friendly, and most importantly super competent! You cannot go wrong using them for your HVAC needs! read more

This company has replaced 2 AC/heater units and provided other services in the last 17 years. I have found all their technicians to be honest and prompt with any service. read more

I initially called Robert out for a simple repair on my older system, and he handled it quickly and without any hassle. Then, just before the recent heat wave, we had Robert and Sons replace our entire HVAC system, including all ductwork. Their team (about 6-8 people) showed up and immediately laid down drop cloths throughout the house. They were respectful, professional, and unobtrusive the entire time. What really stood out was how mindful they were about keeping our home clean and comfortable while they worked. The entire system was installed, charged, and fully operational in about 6 hours--my wife and I were honestly amazed. The level of thoroughness and care they showed throughout the process was exceptional. Robert Hall & Sons is a true 5-star business. I can't say enough about how satisfied we are. Thank you Robert! read more

After really bad service from a different a/c company, we called Robert Hall & Sons. We felt good after talking to Joe on the phone, but we were pleasantly surprised during Joe's visit. Honest, fair, polite, prompt, and professional - all the things we always want from a repair person, but rarely experience. All of those values are here at RH&S!!! We couldn't have more pleased with the service call and with Joe! We've already recommended them to several people and we'll be clients for a very long time. read more

Excellent customer service!!! Robert and his company replaced the rooftop HVAC system for my parents. They were very professional: excellent communication, arrived on time, and did an amazing job. Joseph also fixed my wall heater. I strongly recommend them!! read more

Consistently amazing whether it is for my winter needs or summer needs and heating and air. They are superb their professional, their timely. They are caring. They are truly one of a kind. I recommend them to everybody. I use them in my home and my business and will continue to read more

We are really pleased with the work Robert Hall & Sons did on our home's air conditioning. We needed all new ductwork due to poor circulation from our original setup. They were very good communicators, scheduled the job quickly, and completed it in less than 4 hours! We immediately noticed a difference in our airflow and are really happy we chose to go with Robert Hall and Sons. read more

Mike and the team were honest, prompt and professional. They provided fast, efficient service.

Robert Hall & Sons are amazing, my air conditioning unit stopped working the night before , it was blowing hot air. During a heat wave I called them at 7:45 am they returned my called within 15 minutes. Told me they would be out between 9 am and 1:00pm. Showed up around 10:15. I honestly thought my compressor went and I was gonna pay atleast 1,000. The tech went up came down and told me it was the capacitor and would cost 375.00 to replace. I was so impressed. They were honest, reliable and super professional. Had the ac working within 15 minutes. They are my new AC company. read more

5 stars! Stop searching--these are the guys you want to come fix or install your HVAC. I've relied on them for years and it's always a great experience. They're super fast, honest, their prices are exceptionally fair, and it's an all-around pleasure doing business with them. A friend recommended them to us way back in the day and it's gotta be one of the all-time greatest recommendations I've ever received. These guys do such consistently excellent work. Special thanks to Mike on this last job! read more

Heat went out in the middle of the night. Called for a service call this morning and was told between 11 and 2. He showed up at 5 minutes to 11, asked a few questions, and went up to look at the system. Quickly pinpointed the problem and explained it clearly without talking down to me. Fixed it in about 20 minutes. Service charge fee of $135 was extremely reasonable for prompt, polite and knowledgeable service! And they even take Venmo. read more

Excellent customer service! We run a property management business and Mike helped us narrow down an issue with ease! Professional attitude, great knowledge of the trade and very quick response times. What more could you ask for in an HVAC company? Thank you Mike! read more

Mike Hall responded to our problem, troubleshot, and repaired in quick time and replied to all phone calls in the same manner. Excellent service read more

First time serviced by & Sons and had a great experience, Robert Hall had done a good job teaching the next generation. Replaced my condenser in and out in a couple hours, works perfect and reasonably priced! read more

This is the place to have your hvac done. I had a new install and Robert, the owner, personally came to my house and discussed a plan and gave a quote that was very fair. Work was done as planned in a timely manner. His crew was amazing and Robert was on hand on the first day to make sure things went smoothly. They offer free service for 2 years. They took the time to explain everything. I am super pleased! read more

How many stars can I give? Only 5?! Just not enough for the outstanding job this company did in replacing my HVAC system. Excellent experience and outstanding customer service. I really can't say enough about them. Thanks Mike!! read more

didn't use them, but talked to Robert on the phone while getting quotes, & he was super helpful and gave me good advice. seems like a trustworthy company! thanks!!! read more

Short Review: Quick to respond. Come sooner than later in the given timeframe. Courteous. Helpful. Share knowledge of the situation. A high recommend. Long Review: Well, hell. It's hot. It's been over 95 degrees for about 10 days. And of course the air conditioning stops getting cold. After sleeping with the windows open and drinking 4 bottles of water overnight just to stay hydrated, we called Robert Hall & Sons to come out on a holiday weekend. And they did! They gave us a 4-hour window on a Sunday, and then came within the first hour. Thank goodness. We weee melting! The courteous gentleman who came assessed the situation and quickly found the issue and corrected it. He explained everything that was going on and some of the steps we could take to try and fix the problem ourselves first. That is not the normal service we usually get from these guys, so I was pretty excited about that. Here's the best part..... I had been using a different Air Conditioning & Heating company for over 15 years - and I think these guys are much better! Robert Hall & Sons are now my go-to company! Very happy with their service. read more

By far the best service i've ever received by a A/C contractor. Went above and beyond to make sure my nest thermostat was wired properly and working as it should. Joe was very patient and had great communication. Thanks for your help! read more

I was in the market for a new A/C coil and condenser. I got professional estimates from 3 other HVAC companies, but ultimately chose Robert Hall & Sons because of their fair prices, great reviews on Yelp, Angie's List, and also directly recommended from the manufacturer! How about that!!?? We wanted to relocate the existing 2yr old furnace and the A/C coil from a closet inside the house to the attic. And the condenser was on the rooftop, and needed a change out. This is not an easy job and you need to hire someone that has years of experience and knows what the heck they are doing!! Installation is the most critical component of your new HVAC system and if you hire the wrong company, you will be upset and disappointed with your new system and also wasting money!! Mike Hall came to my property to see the scope of work. He was professional and straight forward. He provided a verbal quote as we discussed options on site, and followed up 2days later with an detailed quote. When we moved forward with the job, Mike said that his crew could bang out this job in one day and that he does this type of job all the time (other HVAC companies were going to take 2-3 days). On installation day, 5 guys and Mike showed up at 7am on the dot, wearing company sweatshirts and t-shirts, were a synchronized team, and Mike even pitched in. That's 6 guys attacking this project. By 8am, the old condenser was out, and new one in. No crane needed. ($500 saved right there!!). By lunch time, the units inside the attic were all in place. Installation was completed, tested, and running perfectly by 3:30pm!! A short time later, I had a few issues with the dampers and vibrating noises from the condenser. Mike came to the house within a few days and made the adjustments at no charge. I am writing this review 7 months after the attic relocation/installation and the furnace worked great in the winter time and the new A/C works wonderfully in this hot summer !! I have only good things to say about Mike and his guys. Fantastic team and great workers! Awesome company, excellent follow up and customer service! Hire them. You won't be disappointed!! read more

I cannot recommend this company enough! It's summer and our AC just wasn't working. I did a Google search and tried my own troubleshooting. I noticed ice on our refrigerant line and Google said we should change the filter. It helped, but still wasn't cooling down our house. So we called Robert Hall & Sons and they came out the next day to take a look. I thought we needed more refrigerant. But after the technician looked at our system, he noticed the fan wasn't blowing as much as it should. So after a few minutes of investigating, he noticed that unit was WIRED INCORRECTLY. He opened up the unit and after a couple of minutes or rewiring, our AC has never worked better. These guys are fast, friendly and courteous, but most importantly, EXPERTS at their work. Thanks again!! read more

Thermostat wasn't working....called Robert Hall. Responded quickly and came to replace thermostat this morning! I'm always impressed with their reliability, fair pricing and friendliness. We've used their services for the past few years and will always do so. Highly recommend! read more

I wanted to take a moment to leave a very positive review for Robert Hall and Sons heating and air-conditioning. I had a big job with two air conditioning units. Robert Hall personally came out and started the job and and that allowed other contractors to do their work; basically saved the project. He was very professional, experienced and knew his trade. Later his crew came to finish the job and connect the units and set them up. Everyone was very professional, knowledgeable, timely and detail oriented. Overall their ac service exceeded all expectations. Besides setting up the AC the crew with Wilson were very upbeat, entertaining and funny. read more

I want to give a shout out to Robert Hall & Sons. My A/C stopped working last night (it's 95 degrees right now here) and I left him a message. He was at my door at 8:30am this morning, on a Sunday, fixed it and I'm back in business. I have been their clients for several years now and they are always fast, clean and reliable. I strongly recommend them. read more

I have been a customer for about 5 years and if you can get a response they do a great job. On their site they say responses are 100% and the response times are about 20 minutes. In 5 years I have never experienced that. It's always several calls and days before a response even during mild weather. Over the last few days I have called repeatedly and left messages with zero response. I know they must be very busy but a response for a future appt seems to be the professional thing to do. I can't complain about the work and the people but what good is it if they never respond. Desperately looking for another company. I have changed my review to 5 stars because Robert came out personally to get the system running again. Apparently they have been inundated with calls and the phone system has been overwhelmed . My system is not the best but Robert did get it up and running in less than one hour. As I mentioned these guys are busy because they are good at their trade. I will definitely continue to use them. read more

I can't say enough good things about Robert Hall & Sons! After a recent lightning strike hit a powerline near my home, my A/C stopped working. Another company told me that the entire system was completely fried and needed to be replaced, which was a huge and unexpected expense. Feeling quite stressed, I decided to get a second opinion and called Robert Hall & Sons. They responded promptly. The technician was courteous, professional, and extremely knowledgeable. He took the time to troubleshoot the issue thoroughly and kept me informed, which I appreciated. To my immense relief, it turned out that only the transformer needed to be replaced. The charge for the part and the service call was very reasonable, and I was thrilled to have my A/C up and running again. This experience saved me a ton of money and stress. What really stood out to me was the tech's honesty. It's hard to find companies that don't try to upsell or take advantage, especially as a woman and someone without specific knowledge about HVAC systems. I feel like I can trust Robert Hall & Sons. They are the only HVAC company I will use going forward, and when my system does eventually need replacing, I know exactly who I'll be calling. Thank you, Robert Hall & Sons, for your exceptional service! read more

Fabulous, responsive, and fixed the problem with no attempt to sell additional items or services. Already passed their contact information to a friend. Would definitely recommend. read more

Of course the AC quit in 105 temps.... on a Sunday. Called and got an 8-12 window for Monday AM. Robert called and arrived shortly after 8 and quickly diagnosed a failed capacitor and (fried hard start kit) Lucky it wasn't worse. He had the parts and got us back in the cool in about a half hour total. not cheap, but you pay for the know-how, experience and response. All Good. Thanks Robert. read more

My AC was making some odd noise while running so I called Robert Hall & Sons based on amazing yelp review. Mike was able come in 30 mins since he was in the area for another job, and he was able to figure out the issue within 5 mins. I am always going to call them as my regular HVAC team from now on! read more

I've used this company a couple of times to keep my ancient AC & heat system going. I was never given some big sales pitch or told I needed a new system; they always got it running each time. Prices were so reasonable and they arrived almost same day each time. During the super cold weather, I was finally ready to upgrade to install a new HVAC as ours was so old and we'd been saving up knowing it was on our list for a new one. They came out and gave me a quote, scheduled it within a week and did a great job. They changed out the whole system, including the ducts. It was a great job and works fantastic. I appreciate reliable, honest companies that aren't trying to constantly up sell you. This company is a keeper, although now that I have a brand new system I may not see much of them. read more

Like everyone else in LA my AC decided to die last weekend. My normal AC guy is only M-F so I frantically was calling anyone and everyone to see if someone could come out. I left a message and Michael called me back within 20 minutes and was responsive and professional on the phone. They were completely booked that weekend but were able to fit me in Monday morning which I gladly accepted. Joseph came right on time and diagnosed the problem (faulty wire) and had my AC back up and running very quickly! My thermostat was also mounted a little crooked on the wall (something that had always bugged me) and he took the time without me even asking to fix it which I thought was a nice personal touch. In the end, he only charged me for the service call itself and it was super easy to pay them by Venmo. It's always nice to know a good contractor and I would not hesitate to call them in the future. read more

Mike Hall helped me by replacing a motor that had failed in my HVAC system. He was prompt and responsive, and the quote he gave was very fair (I did some comparison shopping to confirm). Once I confirmed I wanted to move forward, he ordered the motor and installed it the day it arrived. He was careful in the space where he had to work (a wine storage closet) and made the entire process completely easy on my wife and me. I hope I won't need HVAC work any time soon, but if and when I do, I'll definitely reach out to Mike. read more
