Very happy with my experience

Best experience with the company as they replaced our AC/Heater system. Very professional and informative as they answered all my questions.

Great company!

I had to call Lex Air for some warranty work. Jonathan did an awesome job! He drove all over the metroplex looking for the OEM part I needed to make sure I didn’t have to stay in the hot and humid house muck longer. Thank you, Jonathan!

Val O.


I would highly recommend them.

Lex Air did a great job on the installation of my brand new unit! Great customer service, technicians were friendly and I will definitely be using them to purchase my other unit when it goes out.
