Mr. Adam Chambers (the AC in the company's namesake) was recommended to me by another HVAC tech to…read morehandle regular preventative maintenance on my leased warehouse. I have hired many HVAC professionals, but Adam is now my go-to guy. Besides maintenance, he has: - serviced my large 711-style drink fridge - optimized our HVAC zone ducting - safety-checked and started a retrofitted electric-heating system that had not yet been run under my lease term - replaced a dying compressor on our 3-ton unit - recharged our coolant ...and he has done them all at a consistent and fair cost. Much lower than the previous techs I've hired. He has plenty of experience, as I have heard from the tech who recommended him: they setup full systems for big companies such as Garden Ridge together. After one service appointment awhile ago, Adam mentioned to me he was excited about starting a project with a chain restaurant's kitchen and dining setup. Turns out they loved his work so much that they wanted to contract him for all the new restaurants as they expanded across state-lines. To me, as a businessman, I was surprised to later learn that he turned such a huge opportunity down because it may draw him away from his existing customer base and ability to respond to their service needs in DFW. He has earned my respect and trust by doing right by me and others. Therefore, I would not hesitate to recommend this company to anyone in need of HVAC service.

This was the first time I have used these guys but won't be the last!…read more I called early morning and left a message to have a technician call me to schedule an appointment. Adam called me back about 10 minutes later to say he was in the area and would be right over. I have never received such a prompt response! Adam was excellent. He was knowledgeable and friendly. He discussed everything he was doing and answered all of my questions. As a single mother, and the owner of a "money pit" it's very important to me that I find someone that I can trust. Adam ran through my repair options without pressuring or trying to upsell me. I would highly recommend this company and Adam Chambers in particular!

1 Star -- The worst customer service experience I have had with an HVAC/plumbing company…read more I would strongly caution anyone considering Lyons AC & Heating, especially for a major installation. We purchased a new AC system from Lyons last year, and ever since the installation we have repeatedly had problems with the condensation lines backing up into our bathroom sinks. We have had technicians out approximately FIVE times trying to address the issue, and it is still happening. This week was the final straw. I called Monday and was scheduled for Wednesday. Wednesday morning, Lyons canceled because their technician had a personal issue and rescheduled me for Thursday. I confirmed that I would be home all afternoon Thursday. At 1:30 Thursday, while I was on a work call, they called me. They called again at 1:38. They also texted at 1:31 and 1:39. At 1:48--only 18 minutes after the first call--they texted saying they were CANCELING my appointment because I hadn't responded to reconfirm it. At no point when the appointment was scheduled was I told that I needed to answer a same-day call or text within minutes or they would cancel my confirmed appointment. I had already confirmed the day the canceled and rescheduled that I would be home. What made this even worse was learning that because I am not a "member," another higher-priority job was given to the technician and he would be there for the rest of the day. Meanwhile my sink is over flowing with water from the condensation lines. So after Lyons canceled my Wednesday appointment, I rearranged my schedule AGAIN for Thursday, only for them to cancel a confirmed appointment because I didn't respond to multiple calls/texts within an 18-minute window while I was working.Then when I called them back at 2:09 after my work call, they said they could not reschedule me until next Thursday!! I've also previously paid approximately $500 for them to clean out a dryer line--an amount that, in hindsight, left me questioning whether I was being upsold rather than being treated as a long-term customer who had already purchased a major system from them. My biggest issue isn't that schedules change. Things happen. It is how Lyons handles its customers when they do. After being a multi year customer, purchasing a new AC system, dealing with repeated service calls related to the condensation lines, having Lyons cancel once themselves, and then having them cancel AGAIN because I couldn't respond within 18 minutes, I have completely lost confidence in this company. Customer service should not depend on whether you pay an additional membership fee which I was very unaware that was their business model. I would not recommend Lyons AC& Heating based on my experience.

The only good part of their service call was that they showed up in 3 hours. After that downhill…read more Their strategy was to try and sell me a new unit. They pump up the estimate and try and convince you that maybe you shouldn't invest in the older unit. This wasn't a difficult issue, bad outdoor fan motor. Told me the unit was so old they might not be able to get a replacement (that was false). Then it was, we can get it but it costs $800 (also false) and add labor and maybe a new blade. Seemed outrageous for a pretty simple motor. Told them I had to think about it. Tech said had to charge me for the diagnostic call but if I would authorize the repair right now he would waive the fee. I said no thanks. Went inside and found I could get the motor delivered to me for less than $300 delivered. Found another company that repaired it for less than 1/2 that had been quoted to me.

Sharjeel was extremely detailed, professional, courteous, and thorough. He took the time to make sure the drain line was completely cleared and that everything was functioning and draining correctly before finishing the job. I especially appreciated that he went above and beyond rather than simply completing the minimum required service.

We have used them since 2018 and referred friends, neighbors and family to them. They have always been terrific. But our last routine maintenance on 5/15/26 resulted in our large AC system not working. We called and were told we could schedule an appointment for 5/21/26. We certainly expected they would send someone to us that night since they caused the problem. It was a working system prior to their routine checkup. They did say we could 'try to get on the list' if we called Saturday morning. Otherwise we could make an appointment for 5/21. I called to talk to Tiffany (owner) this morning and was told she was not in today. I asked to have her call me as soon as possible. I was then told she did not work there anymore. I asked if she or the family sold it. I was given a runaround but was eventually put on hold and then the phone call was dropped. When I called back they admitted new ownership and that they no longer offer 24x7x365 service. I pointed out it is on their phone
