Reviews of local pros in Melissa, Texas

We installed our new Nest thermostat yesterday, and I’m honestly impressed! The temperature in the house stayed perfect all night — not too warm, not too cold — we slept like babies. It’s amazing how much difference it made right away.

Thermogrid HVAC did a great job with the installation — quick, professional, and super clean. Definitely recommend them if you’re looking to upgrade your system or install a smart thermostat!

Had an amazing experience with Thermogrid HVAC Corp during my LG mini split installation!
The team was extremely professional — they installed the LG ArtCool Mirror system perfectly, tested the refrigerant lines, and made sure the airflow and cooling were balanced throughout the rooms.

I had a few installation questions about LG multi-split systems and ductless units, and they explained everything clearly — from vacuum pressure testing to condensate drain setup and wall bracket mounting.

If you're in the Dallas-Fort Worth or Allen, TX area and looking for professional mini split installation, service, or replacement, I highly recommend Thermogrid HVAC.

Fast, clean, and detailed — exactly what you want when installing a ductless LG air conditioner or heat pump system.

I hired Thermogrid HVAC Corp in McKinney, TX to service my Rheem water heater (2015). They flushed/cleaned the tank and replaced the anode rod. Everything is working perfectly now — hot water is back to normal, the system runs smoothly, and the water pressure is restored. Professional, on time, and explained everything clearly. Thank you, Paul!

Ray is wonderful technician. I would hire him without a second thought.
He did a great job, finding and fixing my plumbing problems. Thanks Ray

We have used L&S on our personal houses for the last 8 years. Cookie is a dream to work with. Her sweet voice and awesome customer service is so welcome in today's world where that's hard to find. Ray has been out to help on our last 2 houses, and he is such a delight. He is so kind, knowledgeable, and professional. We couldn't be happier with L&S!

I’ve had them out twice now for warranty work. First time turned out to be nothing, but the second time the plumber (James) had to put in some work. He was very courteous and professional both times, and did a great job.

I have issue on my hvac unit thats was installed in a new built house i bought few months ago.Everything went smooth from the representative who took the call and setting an emergency appointment the next day. Mr. Wellington from L&S company came early today didn’t expect that they will be able to send someone this early at 8am. I was happy with the outcome. both my hvac and AC UNITS ARE WORKING PERFECTLY!! In addition he was very patient and very polite . He gave me a good explanation what was issue and how he fixed it. He took the time to answer all my questions..I hope you guys have 100’s of employees like him . He knows what he was doing ,only an experienced personnel have that dedication. I appreciated what he has done 100 folds! my attic is like third floor and climbing up the stairs multiple times is not easy !! Thank you so much L&S truly a great service ! thank you Mr Wellington for a job well done!! I bet he was your finest employee!! thank you thank you!!

Ray was professional and did a great job explaining what he would do to troubleshoot the issue each step of the way. He had our plumbing issue fixed and working again in under an hour.

Jose was very helpful and explained everything that was needed and fixed the issue he had came in for. Very nice and professional.

Ray entered our home with respect and care. He took off his shoes before entering our home and kept his mask on the entire time he was here. He was very knowledgeable and knew right away what the problem was and knew how to fix it. He was professional and provided us with a means of further communication, if ever in need. Thank you Ray!

Ray was very nice and thorough. Excellent service he provided!

Ray was super nice and clearly wanted to get to the root of the problem. Took his time and explained things to me very patiently if how we could approach the situation, even though it was a late evening appointment. Thanks.

Ray came to properly install a dishwasher drain hose. He was very professional and clearly explained the issue and how he fixed it. He has come to our home a few times and each time he is awesome!

Wellington did a great job. Very courteous and having high helping attitude. Though problem at my place was not a big in nature, but he still took his time and make sure all is fine.

The very first thing I noticed about the technician (Wellington) was his professionalism. He was extremely polite and sincere in his service delivery. He quickly diagnosed the issue and our repair was complete in a matter of minutes. I appreciate that Wellington fully explained what went wrong so that I can monitor and prevent future problems.

Ray did a great job! He fixed everything super quickly and took his shoes off before entering without me even asking.

I received great service on the issues we discovered after moving into a newly built home. Ray did a thorough check on all the showers, sinks, tub and resolved the outside drain blockage. Very professional, quick and courteous service!!!

We built with Perry Homes and L&S is the only contractor that has been hassle free and extremely knowledgeable with the services they provide. Jose was exceptional, he deserves a raise! Highly recommend L&S Mechanical if in need of any electrical, plumbing, or gas needs.

Mr Ray did an excellent job in installing Toto in my bathroom. He is trustworthy, professional, and smart in installing Toto. Thank you Mr Ray. 5 Star.

Ray did an awesome job. He cut back our hot and cold supply lines and reset the drain for our new IKEA wall mounted sink cabinet, then assembled the faucet and drain lines from the new sink to the new lines and drain in just 2 hours. Thanks Ray!

Ray was hands down one of the best plumbers I’ve experienced. Very knowledgeable and helpful. He’s a great asset to L&S.
