We called L&S when our AC suddenly quit working this summer. They quickly replied and came over to see what needed to be fixed. Their prices are fair and the crew was on time, tidy, and stayed until the job was finished. We continue to use L&S because of their fantastic customer service!

I’ve been building homes as an independent builder for about 40 years. During those years I have hired many different different HVAC companies. I’m currently in the process of building a workshop and I got six different bids with excessively broad price differences. After much discussion I made a decision to hire this company. I was very impressed with the quality of work they did. The crew was very respectful and easy to work with. They went the extra mile to do things right. I’ll hire them again and recommend them without hesitation.

Want to take a moment to thank Fersa. Great customer service. The guy were clean and efficient. Very nice people in and out the office. I picked their name out of the Yelp pages and I'm glad I did, they are fantastic.

I cannot recommend Luis enough, Im a first time home buyer and I knew I had to replace the air filter every couple months but had no idea about the drain being an issue. The AC shut down today and Luis came out and not only took care of it but took the time to educate me on how to maintain the drain in the house. Will definitely be using him for any future issues.

Our furnace went out the day of the freeze which is coming to Dallas tonight. I called L & S heating and air conditioning And Luis came out and diagnosed and fixed the problem and his price was far lower than I expected.

Responsive and reliable. Came out on a Sunday evening in the middle of Texas summer to help repair my HVAC, within 45 minutes of my call. I could not find anyone else to help me. Fast and efficient, went above and beyond to help make the necessary repairs. Highly recommended.

Luis came out within 30 minutes because he was in the area. My AC was down less than 24hrs since he was able to fix the problem right away. Quick, efficient and great customer service.

We just had this company install our new HVAC system due to a coil leak from our old system. We did not need to go with the new system, but decided that due to the old age of the previous system (over 25 years old) plus the multiple repairs we have done in the past 4-5 years. Luis gave three options for replacement that gave us the flexibility of deciding which one fit our budget and our preference. He was very professional and communicative throughout the process. I will try to get some updates to this review as time goes on.
