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.

Amazing service, did everything perfectly as promised! 100% recommend! You won't be disappointed!read more

J Martin Indoor Air Quality provides exceptional customer service and superior quality…read moreworkmanship!!! We were referred to J Martin by a colleague of ours, and it was the BEST decision that we have made when it comes to HVAC. We are writing today to both share our past and present experience and to praise Jared Martin and his team, whose knowledge and dedication were absolutely invaluable in the service process. For years, we were constantly making repairs to our AC systems. Every summer we would be stressed out about the AC no longer functioning, so we would set the temperature higher than a comfortable level as to not strain the system and in hopes that it would not fail. But every summer something would go wrong and we would go days waiting for a temporary repair. If the upstairs AC went out, we would bring a mattress downstairs and sleep downstairs for days. Thankfully we have 2 separate systems to be able to do this. After 10 years of stretching out our old systems and constantly stressing on these components in our home that are meant to bring comfort, we were blessed to have discovered J Martin. Upon our first contact with J Martin in September of 2025, we had the pleasure of speaking with Ruby over the phone. She is such a kind and sweet person with phenomenal customer service. When we first began looking into repairing our Air conditioner, as with most people, we were a bit overwhelmed. Ruby and the other customer service staff were easy to get in contact with and they scheduled us very quickly. She was extremely transparent with coordinating our requests. She scheduled an inspection for our non-functioning downstairs system and we were blessed to have Jesus Ochoa come to our home. He is an absolute Gem of a human being. He didn't try to sell us on a new system at first, but instead he simply educated us on how the systems work and what the deficiencies in our systems were. The coolant was sub-level, our ducts were undersized and our condenser and furnace were simply old. He informed us that he could fix it and provided the cost to repair the system, but we would run into these problems again in the future (as we had been for 10 years since we purchased our home). The fact that he educated us with things we never had knowledge of helped us to make the decision to just purchase a brand-new complete system. New condenser, ducts, furnace, Merv 13 air filter, etc. When it came down to the day of our install, we felt so comfortable with the lead installer Santiago Nunez and his team Chris and Frankie. They were so courteous, professional and polite. The install went SO smooth and they patiently answered all of our questions and addressed our concerns. They did a great job of protecting our belongings during the install, including protecting our floors, carpets and clothing in our closet. Santiago, Chris and Frankie are the dream team! Last year we knew that we would eventually need to replace our Upstairs system as well sometime soon. We contacted J Martin again in June 2026 and Jesus showed up like a hero. We were already comfortable with his honesty and sincerity. He put together a system for us based on his knowledge of our home and we moved forward with a brand-new complete system. We were SO happy with the Lead installer Irvin and his crew Kevin, Oleyvo and Pablo. They were ALL extremely professional, kind and so considerate. Irvin and his crew went out of their way to make sure we were happy and they even did things pertaining to the system that they didn't even have to do!!! This new system is amazing. We got all of the components as with the previous system downstairs and in addition we got a new attic fan which helps a lot. J Martin also provides maintenance plans for AC and Heating systems as well. We purchased the plans for both of our systems and it is a valuable and necessary option for peace of mind. Shout out to Jared (Jr) for our last tune up!!! A/C repairs can be a very stressful and a scary process. Jared the Owner thoughtfully kept us informed and at ease every step of the way, and with the assistance of Jesus, Donny, Ruby, Satiago's crew and Irvin's Crew, they made the repair process an enjoyable experience. The company was never too busy to answer our questions, and promptly returned each of our phone calls. J Martin earned our trust and respect, and we will not hesitate to recommend them to our friends and family for their Heating and Air Conditioning needs. In addition, we will continue to speak highly of J Maritn because of our experience working with Jesus, Santiago, Irvin and their team. In closing, we would simply like to reiterate that J Martin team are valuable assets to their customers and company. We are confident that J Martin Indoor Air Quality will provide the same unparalleled level of service to their other customers and hope that their excellence is duly recognized.

This is my follow up review…read more I would like to start by thanking Jimmy, the owner of the company for reaching shortly after I posted the review. Jimmy is a professional, a man of God, a pererson with integrity, and a humble heart. Quickly did he offer to make things right and I gladly gave him the opportunity. He checked my file and clarified the financing wonky loan statement by the finance company. Everything was cleared after I spoke with the goofy finance company. After I explained to him my first day experience and my zoning situation, Jimmy refunded me $419. Jimmy when beyond and with persistence to make thinks right and have a happy customer. I live and work by the same standards and he highly deserves 5 stars. Thanks Jimmy! You're a great businessman and a Godly man. You have won my future business and I will highly recommend you. Thank you & God Bless you, your company & Family!

My AC started leaking out of nowhere due to a blockage and Airflow Bros was able to squeeze me in…read morefor a last minute booking. 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!!

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!

Definitely not substandard quality. Definitely not "Mickey Mouse" work. *2019 - I had new air conditioner ducts installed, because the old one had asbestos. Although I was informed that as long as you do not touch the asbestos, it was "safe", I decided to replace the ducts. *July 10, 2020 - GC HEATING & COOLING installed a new AC system *Jan. 19, 2021 - GC HEATING & COOLING adjusted the offset pressure at gas valve because it was not working. *Feb. 12, 2021 - GC HEATING & COOLING had to replace the inducer motor. *August 9, 2024 - I posted a bad review of GC Heating & Cooling on YELP. 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
