Reviews frequently mention fast scheduling, with several customers noting same-day or next-day service. Communication from office staff and technicians is highlighted, including clear explanations and written estimates. There are a few negative reviews citing delays in receiving estimates or dissatisfaction with workmanship. Overall ratings trend positive with praise for professionalism and punctuality.

I am with military over seas. My wife called and said the ac was not working. We looked online and saw great pictures and reviews. We called for a estimate they came out that same day. Tech was great he spoke to my wife and also talked to my over the phone and answered all my question and concerns. We got a typed estimate within 1 hour to our emails and text message. We chose the best option for us they were installing next day.
It was a easy process and I was always informed of everything even though I'am overseas. I high recommend this company.

After several unsuccessful attempts to have another company inspect our HVAC system, I contacted Texas Lone Star, and I’m glad I did. It was refreshing to communicate with a well-organized and professional company. Belinda was friendly, efficient, and knowledgeable. I was very impressed with her attention to detail. She arranged for a technician to come to my property on the same day as my call. The technician arrived on time and resolved the issue. I also really appreciated the before-and-after pictures.

I Called about an estimate for a new hvac system for my home. They sent out a tech to chk out what i needed. That was a week ago. 7 days later- no estimate, no email, no call back. Nothing. Nada. Nice way to do business ??

Don't bother with them. My 16 year old could have done a better job. And they wanted over $900 for this.

Overall great company! Liza provided great customer service from answering all my questions to setting up an appointment. The technicians were very punctual and right to the point. They trouble shot my ac unit while explaining everything they were doing and answering all of my questions. The job couldn't be done in one day so they did what they were able too and I was scheduled for another day to complete the work. They came back and finished everything in a timely manner. They have earned a lifetime customer with me and I will definitely be recommending them to friends and family. Keep up the great work!
