Thanks to yelp, I found Thomson Hvac The tech and I thought it should be a simple fix. He inspected my entire system, diagnosed the problem, and quoted the job. We moved forward with the fix, and it worked fine, and then it didn't. After a few more visits, and some more parts and tinkering, it finally started working properly. Although it was a strange and difficult situation, they stuck to it until the problem was resolved. The techs Danny and Mark went above and beyond to make sure everything was good. Another thing to add, the way the company communicated back and forth with me was great. They answered every call and every text. Most of the time I spoke with Stacey and she was great. If you're looking for an honest and professional company, this is it.

My mother recently engaged a service provider for routine maintenance on her air conditioning unit,…read morewhich included the installation of a new Honeywell thermostat. Subsequent to this service, she has reported that the air conditioning is not effectively cooling the premises, with only the fan operating. I advised her to adjust the thermostat to a lower setting. Given her advanced age of 90, her discomfort with the warm air became increasingly pronounced. Today, in collaboration with my brother-in-law, we investigated the issue. We observed that while the unit appeared to be functioning, it was not producing cool air, despite the outdoor fan operating correctly. During our investigation, we contacted the service provider, Thomson. A representative stated that only the thermostat had been replaced and that a service technician could be dispatched for a fee of $159, suggesting a potential wiring issue. Upon reviewing the Honeywell thermostat instructions and wiring diagram, we identified that the thermostat had been incorrectly wired to the "W" terminal. After rectifying this wiring error, the air conditioning unit resumed normal operation, producing cool air. I subsequently contacted Thomson for clarification regarding the initial service. Their response repeatedly referenced a previous replacement 14 months prior. While their online reviews are predominantly five-star, our experience suggests a lack of professionalism. This incident raises concerns about the necessity of recommended services and the quality of workmanship, potentially indicating errors or intentional oversights during the initial installation.

I was slotted for 12 to 2 and they showed up at exactly 12 on the dot. They even had shoe booties ready so they werent walking through the house with dirty shoes. Rebooked them again later for AC maintenance and a different employee showed up right on time for that appointment too, so it wasnt just a one time thing. What I appreciated most is how knowledgeable they were. They took the time to actually explain what was going on with the AC instead of just throwing terms at me. Ive had techs in the past be condescending or vague on purpose, but that wasnt the case here at all. Customer service was great throughout the whole process. This is going to be my go to for any AC or heater issues from now on. Thanks Andrew and Peter!!

My A/C needed repair during the recent Los Angeles heatwave, so I had an HVAC technician come out…read moreto diagnose the issue. It turned out there was a leak and the system needed a Freon refill. However, I wasn't satisfied with the estimate I received for the repair. I decided to call around for a second opinion and had the pleasure of speaking with Andrew from Air Flow Bros. After explaining my situation, he took the time to clearly break down why a Freon refill might be necessary and what I should be looking out for with my A/C system. He also shared some helpful tips to keep in mind moving forward. What really stood out was his honesty. He actually encouraged me to go with the best price and mentioned that if I needed anything further, he'd be happy to come out and take a closer look. Overall, I really appreciate Andrew taking the time to provide thoughtful guidance over the phone. I would definitely reach out to him again if I have any future concerns, and I highly recommend giving him a call if you need A/C service. Thank you Andrew!

Kirk was FANTASTIC! Our unit is 20 years old, we have never really had regular maintenance on it. He showed up super early (they asked if that was okay, and YES thank you). Before he arrived they sent a text with his name and photo. I absolutely love this! That extra safety is so important. Kirk looked at our unit and asked some questions. He explained all they do with the "family plan" so we signed up. I am one of those that needs to be reminded of scheduled upkeep so this is perfect. He gave us the estimate before he started and I asked for a very rough estimate of a new unit (having no idea) so we decided to go with repair and hope for the best. The repair wasn't cheap but considering all the work that needed to be done as well as it being an older unit, I feel it was a very fair price. I think we did have the best with Kirk. He was able to repair our unit and give it some much needed TLC for our AC unit and furnace. He even installed our pre-purchased thermostat! Kirk was polite and considerate. He took time to answer all of our questions and ensured us that we could reach out with any questions, I believe him. Service people can often be rushed, there is a lot of work out there, but not Kirk. He didn't waste time either, I felt like he was in and out in no time at all. By the time he left we understood all that was done and what we need to do to get some additional service from our current unit. I could not be happier with the call I made this morning. I picked the right people to call!

Someone was scheduled to come out two days later. However, at the end of the call I was informed that Veteran Air was no longer in business and had been acquired by Dial One. I thought it was a bit odd that they waited to long to tell me considering I told them I was referred by a prior customer. Anyway, two guys showed up on the early end of the window and did their thing. I was told I would have a quote by end of day and they would follow up with me to go over the quote and answer questions. Five days later, I haven't heard a word. Weird way to conduct business. If they didn't want the job, they could have told me when they were on site.

The owner, GUSTAVO CANO, reached out to me, and we discussed my issue. He convinced me, that the reason I was having problems with my unit, was because I did not agree to allow him to replace the ducts. He said the solution to my complaint, was for him to replace the ducts. *August 15, 2024 - GC HEATING & COOLING replaced my ducts, and I paid them $5,200.00. I took down the bad review on YELP. *September 17, 2025 - I called Gustavo Cano about issues, and he was visibly upset, and combative. He said he was coming, but that he would charge me if my complaints were unfounded. He never showed. My issues are the following: 1. The strap of the duct fell off. 2. SEALP Plenum duct sealing - NOT FULL SYSTEM 3. Type of Ducting/Condition : MYLAR not sealed. My AC system was installed July 10, 2020, six (6) years ago. Now, apparently, it has a leak. My old YORK air conditioner was twenty (20) years old when I had it replaced. It never broke down. I religiously have my unit cleaned, and turned up yearly by professionals. GC HEATING & COOLING is just very disappointing. If you value your money, then please learn from my experience. DO NOT HIRE THEM. Olivia Soriano
