Used reliant for the $85 maintenance tuneup. Tech Scottie was great. He kept me informed every step of the way. He showed me pics of everything he was doing. Lots of good info. Some stuff i needed to address before they became more serious. Overall very good experience. Will continue to use them for all of my HVAC maintenance and repairs. read more

Update #3 -- As I previously stated I've used Reliant for the 4.5 years. They put in the new unit I purchased 4.5 years ago. Things were running smoothly with my unit, absolutely no issues. I get a call from Reliant asking if I would like for them to come out and to my winter service. I said yes, and we scheduled for Friday, January 19th, 2026. They were supposed to give me a 30 minute notice prior to their arrival, but nooooo, they call me when they are already at my house. So I have to rush hone from my job to meet the technician. The technician was there for a while does his thing and then leaves. Well about 15 minutes after he left, I noticed my thermostat was totally black, would not come on. I immediately call back and tell them he needs to come back as the thermostat will not come on. He comes back and after an hour he tells me the problem is the breaker ; that it is too small for the unit. and I need to call whoever put in the unit to fix. To which I replied "Reliant put in the unit". Not only that, but you guys have come out twice a year every year and checked the system and no one ever said anything about about the breaker being incorrect -- EVER! The most frustrating and annoying thing of the cluster fuck was when the supervisor Matt proceeds to talk to me in the most condescending manner and tells me, "well at least we are not charging you. To which I replied yes you are charging me, $250 for yall to come out. He said well at least we are not charging you to to trouble shoot the problem -- well hell no being that your technician caused the problem; and we are not going to charge you to replace the breaker; and you shouldn't! Because if another breaker was needed that should have been done at installation. I don't see how that breaker worked for 4.5 years and them WHAM breaks after your tech jiggles with my system! MY system was working just fine before the TECH touched it! They finally jerry-rigged the system to work to get me through this current winter storm, but I was informef that I would have to constantly run it in auxiliary mode until they get the issue resolved, which means my electric bill is going to be through the roof! So quite naturally I want them back as soon as possible to get it fixed. Was told someone would call me on Monday...didn't happen. So I call them today (Tuesday) and the lady that answer the phone said her supervisor doesn't know anything about it. I said ma'am, you were the one I talked to, to get the tech back over to my house, so you are aware about this and so is Javon and his supervisor Matt. So that's who you need to talk to. I was told by Javon that the order was already entered (and he also told that to the second technician that showed up at my house on Friday). A simple tune-up has turned into a total clusterfuck! Someone is supposed to call me tomorrow and I will update from there. But I have a feeling they are going to try and get out of putting my system and breaker operating condition the way it was -- I pray I'm wrong. But right now I have little faith in them. Because 1) I loath being talked to in a condescending manner and 2) Once you break something you are supposed to be fixing once, my radar is already on high alert. Stay tuned. UPDATE 4: I am happy to share that Reliant kept their word, replaced the breaker and got my system back to its original state. The best part was the technician Johnathan didn't speak to me in a condescending manner and treated me with respect. read more

Reliant Air Conditioning - Voicemail from Technician on 9/22 - Heating & Air Conditioning/HVAC Near Me - Irving, Texas

See all

I'm extremely disappointed with how this situation has been handled. We had a brand-new HVAC system installed recently, including a heat pump with a 15 kW auxiliary heat kit upstairs. Once temperatures dropped into the teens, the upstairs system could not maintain the setpoint and fell into the 50s overnight. I contacted the company to request urgent service given the cold weather, but the response was dismissive, and no effort was made to address the issue promptly despite the system being brand new and under warranty. A new system with electric auxiliary heat should absolutely be able to maintain indoor temperature during freezing conditions. At this point, I have no confidence that the system was properly commissioned before sign-off. I hope this gets resolved quickly, but based on this experience, I cannot recommend this company for installs that require attention to detail or post-install support. read more

Reliant Air Conditioning - Heating & Air Conditioning/HVAC Near Me - Irving, Texas

I've now had them out 3 separate times for the exact same issue, and every time I schedule another visit they want to charge me an additional diagnostic fee. Extremely frustrating to keep paying diagnostics when the original problem still hasn't been resolved. At this point it feels less like customer service and more like being charged over and over without an actual fix. read more

Jeff Stewart who us really the owner but calls himself the business manager said a few days ago that they understood my frustrations that I have had with his company but they were here for me. Ten about two days later I was told that they would no longer service my account. I had paid for their Hero service and for the second time in just a few years the did not do the service even though it was paid for in advance and had been for many years. Just calling in to see about the service they were very snotty. So now lets go a little further. They recently told me about a service that I needed and they would charge $5.000.00 just for the labor and me not really trusting what I was being told got second opinions from the following. Carlos Martinez who works for a local architect George Wayne Mechanical Daffan HVAC All three of these opinions told me I did not need that service so what does this tell you about Reliant. I could go on and on about different things that were out of pocket. Just remember Hero service is just there to hook you if you fall for their B.S.. read more

I had heard great things about Reliant but our experience has been disappointing. The crew threw our Christmas decorations on to the exposed insulation in the attic, they left insulation in the vents that then blew all over the house, including our kitchen where we prepare meals. There is also a very loud rattling in our bedroom vent that was not there before the work. I contacted the sales person and CRICKETS. No follow up whatsoever. If you plan to spend the price of a mid size car with an AC vendor, I would be careful with these guys. $30k in work apparently doesn't mean much. read more

Technician was polite and professional. I had them repair my AC unit. Price was a little higher than I expected. Service charge + the repair. read more

Unethical, Incompetent, or Just Plain Lazy? You Decide I called this company to service my AC because it wasn't cooling properly. The technician showed up, diagnosed that the system was low on refrigerant, and immediately refilled the Freon--without even mentioning that he suspected a leak, much less checking for one. Here's the kicker: the refrigerant leaked out AGAIN just days later. Only then did I get told, "Oh yeah, there's a leak in the system." Seriously? Why wouldn't you check for a leak before recharging it? That's HVAC 101! Turns out (and I've since learned from others and online HVAC forums), recharging a system without checking for leaks is a common scam tactic. It guarantees another service call, more money out of the customer's pocket, and does absolutely nothing to actually fix the root problem. So either this company is wildly unprofessional, or they're knowingly running a cash-grab operation. I feel taken advantage of--charged for a temporary band-aid and left with the same broken system. Now I need to pay someone else to do the job properly. Avoid this company unless you enjoy throwing money into the wind. Mr. Quiroz (The Customer Service Manager) will call you t say tough luck if you call to escalate. DO NOT USE THIS COMPANY FOR ANYTHING!!!!!!!!!!!!!!!!!!!!! read more

I bought an A/C unit from Reliant 3 years ago. They have been out to service it 3 times and it has been a complete disaster! The first time he said I needed a part replaced and then proceeded to quote me a price. I told him I had 10 years parts and labor warranty. They NEVER had it listed in their system. Glad I kept all the paperwork. The second time they NEVER showed up! I called and they said they would have to reschedule because he was running behind. No text, no phone call, NOTHING!. I wasted 4 hours waiting. I have waited a couple of months to have the A/C tuned up and they were supposed to be here this morning. I never heard a word from them the day before confirming the appointment so I called and was told he would not be there till later in the day. Again no phone call, no text. It is as if they are a company living in pre-technology period. I still have 7 years left on my warranty with this clown show. The owner on the radio sounds great but i would not trust them AT ALL based on the way they treat their customers. read more

Dre did a great job while I was stuck in a compliance call. He even waited a bit at the door for us to answer - couldn't get a break. Thanks!! read more

My technician, Dre, was helpful and very polite. He worked quickly and was thorough in his report to me.

Thanks, Dre, and thank you Reliant! read more

Horrible customer service, they don't call to confirm appointment. Spent all day waiting on them on Veterans day and took the day off from work to find out they would be out between 5-7 pm. I cancelled appointment and Service contract. This company is not a HERO but a ZERO. CALL SOMEONE ELSE!! read more

Taylor was very professional and explained how the AC system works. Reliant has knowledgeable and experienced technicians. Thanks Taylor read more

I have a saga going on. First let me say that we have been using Reliant for more than 20 years (since we bought the house) and have always had excellent service and positive experiences. We had a complete replacement system provided by Reliant a few years ago. My wife scheduled our semi-annual tune up on Friday July 18th. It should have been simple. Unfortunately when the tech left our upstairs unit would not run. In fact, there was no power to the unit at all. They sent another tech and he said the switch in the attic failed. I thought that is an odd coincidence. He put in his notes that he told us we needed an electrician. I called Reliant again and explained what was going on and they sent another tech that the breaker failed. The breaker and switch have been replaced and apparently there is a short somewhere. I am having the electricians determine the problem. Here is my issue, my expectation was that when the first tech completed the tune up the system would work at least as well as before. The system was working fine before the tune up. This could all be a coincidence, but the odds of all those failures occurring at the same time seems astronomically high. I am hoping for some solution, but I believe I will be on the hook for some serious electrical repairs and looking for a new a/c service provider. read more

I called Reliant on May 24th, 2025 for service on my AC Unit. The unit was not cooling the house but the outside and inside fans were still working and I had just replaced the capacitor about a year and a half ago. When I replaced it back then both the fan and the compressor did not turn on. At the time I was not aware that the capacitor was a duel capacitor so this time I did not expect it to be out since the fan was still working. I instead thought it may be the the unit was either low on Freon or the compressor failed. Since I had my son's graduation that day I did not have time to thoroughly investigate the matter. When speaking with the operator she offered to give me a discounted diagnostic fee which I really appreciated. Reliant did send out a tech that day and he did diagnose the issue quickly and replaced the faulty capacitor. I was really happy with the quick service and the AC unit did start to cool down the house. The one issue that I had was besides charging me the diagnose fee they also charges me $340 for the capacitor. The installation took about 10 minutes and the tech stayed around 20 more minutes to verify the system was properly cooling and that the Freon levels looked good. I am not sure what amount of the $340 charged for the capacitor was for the part and what amount was the labor. I do know that the retail price I had paid before was about $16 for a capacitor but that was a year and a half ago so the price may have gone up a bit. I feel that they over charged for the capacitor, but since I did not exactly remember what I had paid I did not realize the over charge at the time. I caution readers of this post to be aware that they had over charged me for this part. I understand the cost of doing business but I think a total bill of $409 for the repair is a bit much considering if I had done it myself it would have cost me under $25. In general they did fix the AC Unit quickly and the repair tech was very knowledgeable and professional. I did want to add that I had used Reliant several times in the past and their pricing seemed very fair at the time. Also as stated above both the repair tech and the operator did honor the reduced diagnose fee which I am extremely grateful for. read more

We bought a 16k unit that was installed less than 2 years ago and it recently went out because a part failed. We were told that we would be notified of the status of the part and updated on the process then contacted for a revisit to replace the part. By the way, even though its still under warranty, we had to pay 100 dollar fee for him to diagnose it and we still have to pay 300 to have it replaced. We went all week long with no response or contact so I reached out that Friday. They had already closed for the weekend and the system had no mention of my part. So, we waited through another weekend with no climate control. I had to call them back again this week to ask what was going on when I was finally advised that the part had been ordered and they would reach out to schedule when it was on hand. Yesterday, they contacted me that the part was in and the tech would be coming in the afternoon to install it. They just dropped the part off at the front door outside while no one was home with no communication about it. When the tech arrived, he worked for a while and then told us that the new part would not sync to the unit for some reason or another related to an app that is necessary. He told us that we would be contacted to schedule a revisit some time today. When they reached out, they talked like they had been expecting me to be sitting there waiting for them. I explained that I was not able to waste a whole day while they figured out when they would address it and asked for a time frame. They couldn't give me a time frame unless I made another appointment further out. So, I told them I could leave my job at noon and be home by 1230pm. I was told that no one would be there before 1230pm. I just got a message that the tech is expected to show up at 1150am. This company has shown us, and I imagine others, that their concern is not about providing honest and reliable service after the sale of honest reliable products. Their focus is on selling new units to clients they can cast aside when it all falls apart. Do yourself a favor and explore other options if you want a reliable product and good service after the sale.​ read more

Problem was finally fixed, even though it took them years to figure it out. I say they figured it out... We will find out next season. It takes a year for it to rear its ugly head again. Every year I was having to pay them to come out and put Freon in one of the units. And of course that was not free. Also, it was very expensive today. Labor was almost $850 an hour. Yes, just labor! And that is not a typo. Not $85 an hour, $850 an hour. read more

Wonderful experiences every time over the last 8 years as customers. We've had 2 systems installed in the last 7 yrs at 2 different homes. Great specials each time, thorough discussion of our needs, budget and air quality goals. Our sales lead both times was Allen and we trust his expertise and have never felt oversold. He tells us what we can achieve with a minimum unit or with bonuses. Very responsive to questions and walked with us every step of installation and follow up adjustments. Both homes we went with a variable system. Love them! Whisper quiet and big savings on utility bills. Our first home was all electric, this one has a gas furnace. We had a Lennox in first home and Carrier in our current. Also highly recommend the Hero program. I forgot to set up autopay with last units purchase after first year expired that came with system ... and they didn't penalize us for it when we called for our spring check up. All of the technicians over the years are professional and knowledgeable. Always explain what they're doing, any issues addressed, etc. A+ all the way. read more

I have been a long time customer, 16 years, and have been a Hero Club member that amount of time also. Each year, I schedule my spring and fall tune ups like clockwork. Today, once again, Reliant Heating and Air called to reschedule my Fall Tune Up the day of the appointment an hour before the appointment window. Once again, I took a day off from work to be home. As a teacher, my days are precious because if I don't have days to take off, I lose a day of pay. So, I don't waste them. Calling a client, whether new or loyal, like me, an hour before the arrival window opens is unacceptable and shows a lack of understanding, as well as an inconsideration for customers time. You withdraw my Hero Club membership amount on time each month but can't provide service that I've paid for a thousands of time over. Now, I have to wait the entire month of December for you to honor your contract. I certainly am not wasting another one of days. After 16 years of being a loyal customer, I am sure I'll be looking for another company to not only provide timely tune ups but to replace my HVAC system when it's time. read more

Reliant was absolutely incredible. From my initial call, to my consultation with Chris Morrison, and subsequent installation in a two day turnaround. The installers worked diligently all day, and even into the dark. They also took the time to help shore up an existing system that was improperly installed a couple of years back. My only concern, and subsequent recommendation to the company would be that at least one of the team members be proficient in English. I don't expect poets, but a functional ability to communicate in their area of expertise is vital. Functional language capability in a specific metier can literally be achieved in one week of immersion. It makes everything flow smoother, and shows respect for the client. read more

We purchased a new air conditioner and it was installed May 14th. May 15th they come back out to put in a new thermostat because the one installed the day before isn't working. The attic ladder was not reinstalled correctly, and the ceiling and frame are damaged, which prompted me to contact Reliant again requesting the unit be inspected to ensure the unit was installed correctly. They schedule this for May 22nd. May 20th, it's not running correctly and blowing hot air. Technician supervisor came, for all of 10 minutes, and "fixed it". I'm told a manager will still be coming to inspect the unit to ensure everything else is installed correctly on May 22nd (no time window at all). May 22nd comes, 4:30 pm I get a call saying the inspection needs to be rescheduled. A technician supervisor and the city inspector come May 23rd. Another 10 minute "inspection", no problems. May 29th, the contractor hired to fix the attic ladder and ceiling damage comes and confirms it is not installed correctly. He fixes it but the cosmetic damage is still obvious. At this point I'm over it and will just fix that myself because I've already taken too much time off work. June 6th, the air conditioner is again not working, just blowing hot air! Somebody else comes out at 9:30pm. There's a leak in the attic. And nobody has caught that. The technician isn't able to correct the issue, so someone else has to come back out to fix it and they will reach out to us the next morning. June 7th, Nothing. June 8th, I reach out again and am told they will get me in the schedule. Nothing. June 9th, I was told they didn't even have me on the schedule for a call back or anything. June 10th, two technician supervisors came and were here for about 4 hours. June 30th, we notice the outside attic drain is flowing water like a faucet. Luckily my husband was able to correct that. So 1 1/2 months of issues AFTER installation of a brand new unit. It has been a nightmare, extremely frustrating, and has cost us time and money. I cannot recommend Reliant to anyone. Customer service manager, Richard, reached out 2 days after leaving my review "to try to make things right". He said the issues we had were minor inconveniences and nothing substantial, and sometimes these things just happen. Definitely didn't feel like he was genuine. Still wouldn't recommend! read more

Got it fixed! Part had to be ordered and we received updates along the way. Thorough service until our unit was repaired

Jeff, It has been 4 months since I left that review, and you are just now getting to it? Look, I am an easy going guy. When your installers came out to do the initial installation, they broke down about 4 miles from my home. I went to their location, picked up the crew and made 3 trips to get all the materials transported to my home. I also provided a small propane heater for them to try to warm up during their breaks. And, later that day, the business vehicle was brought to my place where they replaced the fuel pump in my driveway. I didn't call your company to complain about them being late, and having to help them get the job done. I tried to be part of the solution. I would expect something like, "I am terribly sorry to hear about your problem, and I am glad it was brought to our attention so we can train our employees, provide them with the basic information for the product, and have at least one person on staff that can answer basic, technical questions about the systems we installed for our customers." read more

Best Customer Service, highly recommended for all AC needs, my Technician was great!

Top-notch service to keep my AC system running. The technician thoroughly checked and cleaned the equipment. He showed me photos of each part of the system that was checked, and he thoroughly explained why he recommended replacing two parts. He was able to replace the parts and inform me of the warranties. While I was not glad to have to spend money on new parts, I am glad that my AC system is set up to function at full capacity and that I won't be surprised by any AC failures this summer. read more

They got here promptly asked a few basic questions and went directly to work. Got both ac and heating taken out and installed new. The installers were highly skilled, efficient and wasted no time. Six hours to do a take out and new installation. Upon completion they took the time to explain everything, and conducted a walk through of the components and operations. Im really glad i went with Reliant, who has been in business for decades and will.be around for a long time. Im glad I got a American name brand in Lennox, and the price was not outrageous. Reliant honors military and provides discont. An Most of all, my wife is extremely happy. (Going from window ac units to central air) read more

After a 3 week trip came home to no A/C. My a/c is 20 yrs old. Called reliant (i have used them in the past), they tried to get someone the same day but could not. They came promptly the next day. Never tried to tell ne the unit had to be replaced just diagnosed the problem in my case a bad switch and replaced the part. Service tech (Yorman) was extremely courteous, knowledgeable and quick. Got me up and running quickly. The price of the switch was more than I expected but quality of service outweighed the price. I will always recommend this company read more

Made an appointment 1+ month out for A/C servicing. They could only give a 5-hour window (12-5pm), so I stayed home from work and even moved work meetings.
