HVAC reviews in Houston, Texas

Great staff

Maybe don't ride people on the hwy ! You will still get to your destination

The drivers of this company suck, they are careless drivers and they will don’t even care if you have the way

Worst company ever. Company is completely unorganized. They have more excuses then solutions. Over half the company are not certified, and can’t complete a job on time due to all their under qualified staff and equipment not arriving on time. I would think twice about ever using this company. And Blake helms is a Project manager for the company. That’s why he is the only 5 star rating.

On my way to work this morning and truck 154 is cutting in and out of traffic driving extremely bad. Please be more aware, the job will be there.

Not dependable at all. Due to the pure lack of Infinity Systems ability to be professional, or even slightly customer focused, I have submitted a request to cancel any future expectations or understandings of us having a contract with them.

Not only is Infinity Systems, Inc. incapable of returning multiple calls, but they also are incapable of scheduling a technician as stated. I filled out all paperwork immediately as requested on 7/31/2023 for Donna to be able to schedule a tech to come out on 8/1 because there was not availability on 7/31. I was told a tech would be out to our office the next day.

Beginning this morning (8/1), I started my day with calling to speak to someone to be given a time of arrival. At 8:49a, I called back and was told a dispatcher would return my call to let me know. Of course, that did not happen. I then called back to ask again, at which point I was told no one would be able to come today because a tech called in sick. I asked if our tech called in sick, Donna then confirmed a tech called in sick. I then asked if any person had been assigned to our call to come out today, at which point I was told yes. Donna then stated that a person was assigned to us but he had to be called to another job because the repair tech assigned to that job is the one who called in sick. I then said that we needed someone here today and that we are 28 floors up, not able to open a window and have a secure room that does not have air conditioning. I said that it is not acceptable to push us to the side for another day because “their” repairman called in sick and not ours. She then said that she could get someone out at 5 or after today. I said great! She then responded with saying it might be 7, I said I didn’t mind at all that my priority is to have someone come fix the issue that their guys were supposed to have fixed three times previously. Donna then said it might be as last as 9, and I said that is fine also!! Not a problem, I will wait for the tech to show up and she confirmed once again that someone would be out, and that she would call me at 4:30 to confirm one last time if they are able to make it or not. I told her thank you because I really did not want to wait around the office until 9 with no one showing up.

Donna then called me at 4:07p confirming someone would be coming this evening after 5 today. I have since called 3 times and been told the call center has not been able to reach the on-call rep. I have now called Donna's cell and left a lengthy voicemail explaining why I am not wanting to continue being failed by Infinity Systems. I had yet to come across such an incapable customer service company, until today. Disappointing would be a gentle phrase.

Infinity was the default ac maintenance provider at my business. 12 hours after they came out for the first time my ac stopped working. I had another company come out who determined loose cables had impaired my unit. Infinity also sent me a $1000 bill despite having a contract for maintenance at a set rate of $295. I do not recommend this company at all.

Please check driver, who ever is behind this wheel is literally about to run you off the road driving reckless and terrible, why hire someone that put others in danger, terrible and ridiculous…

5/26/22, 6:44 AM on 45-N in rush hour traffic. This individual was driving wreckless. Perhaps he had an emergency, I pray everything is alright. Turn on your hazard lights. It is not worth it to drive wreckless.

Perhaps you are the owner, or just an employee. You are representing your company and in a VERY poor way. I hope it was worth it. From the looks of the reviews it seems like you all have a problem.

I would and will never do business with a company that treats potential customers and human beings, in general, the way that this gentleman did. I will also make sure to spread the word of my experience.

PLENTY of other companies to choose from.

God bless and take care.

I stopped by this location while searching for another business in the building and had a very unpleasant experience. When I approached the entrance, I was met by a red-haired woman who appeared to be in her 50s. Before I could fully explain why I was there, she stepped outside and abruptly asked if I needed help and whether I knew why I was there.

As I attempted to explain that I was looking for someone to complete a notary service, her reaction and body language were dismissive and hostile, and she looked at me with what felt like clear disgust. The tone and behavior came across as rude, unwelcoming, and unprofessional, and honestly carried the energy of microaggression that people of color are unfortunately familiar with.

As a local resident, small business owner, and Black professional in this community, the way I was treated was unacceptable. I walked away feeling disrespected rather than helped.

I would caution anyone considering doing business with this company to pay attention to how they treat people—not just customers, but the community members around them. Professionalism, respect, and basic courtesy should be standard, and unfortunately that was not my experience here.

Good service. Thanks

It was incredible work they had done to our house. We were strangling to find good company who can able to fix our coil system. They are amazing finished work fast and also they are so nice and clean. They vacuum all around the AC area and set up our AC before they leave. Very good and affordable price. Trustworthy people. Thanks to them our AC working very well now. Definitely recommended.

I am a real estate investor-
After a horrible experience with another ac company I was recommended to Markor. During my initial consultation I was impressed with Muddassir’s knowledge about how to get my AC system to blow efficiently in the entire home. During the consultation He literally climbed in the attic to view all the ac parts and evaluate the location of the ducts and then explained to me in terms I could understand what needed to be done. He even installed my new AC Alexa thermostats. Since he has done work I have not had a single complaint from any of my tenants. I ended up needing an additional unit as the current tonnage of the existing AC wasn’t enough.

Muddassir is EXCEPTIONALLY professional. He was calling me! He always kept me updated on manufacturer part availability and gave me options if a certain brand wasn’t in stock. As with many contractors you have to hunt and chase them or they just flake also you don’t always know if the parts are new. For me Markor picked up supplies same day as he did the work so I know they are new.

Added bonus that he’s also hands on and INSURED. Even though he is an engineer he is very active on the projects and ensures it will be done correctly. He actually reminded me that they needed to check on some unresolved duct work and fixed it for free!

Tired of flaky contractors, uninsured? Or just giving you the runaround? Use Markor and thank me later!

i had posted an earlier negative review for this company but am happy to take this down and report that Mudassir came back and made a number of attempts to resolve the problem. First the condenser coil was replaced, then the evap coil replacement. This is really rare in this market. Appreciate their follow up to resolve a complicated AC issue.

One star for L&S, five stars for Harold. We had just purchased a brand new house on a Wednesday. A problem was noted with the HVAC system when we moved in on Saturday. When we contacted L&S, they indicated it was not an emergency and would send a tech out on Monday. I’m not impressed with the company at all. On Monday, Harold was sent out and was very good at diagnosing and fixing the problem. Two units were wired incorrectly. Harold reworded the units correctly and no problem has been noted since that time.

Rory is the best. Knowledgeable, and respectful. L&S is lucky to have him. He has been sent to my house on a few separate occasions and each time did an outstanding job.

Came in to fix a hose on my dishwasher. He was fast and knew exactly what to do and explained to me everything he did. Very professional! Will recommend this company to everyone!

We scheduled L&S Mechanical for HVAC and Plumbing. They responded quickly, and both service techs were friendly and professional. We have them scheduled annually for routine maintenance. Definitely recommend!

He was here in a timely manner. Found the issue and resolved it quickly and then explained the process of my drywall being replaced with the home builder very well. Recommend 10/10

L&S Mechanical is very professional and addressed all of our concerns. Our technician, Joseph Mets, was very knowledgeable and very informative about what our issues were. Even though we are out of warranty, he still treated us and our problem as if it was. If we ever have more issues, I’ll make sure to ask for Joseph!!

Will Barker Jr. repaired some warranty items at our house and he was professional, had a wonderful attitude, smiled and did an amazing job! I give him and this company 5 stars!!!
