Was having issues with AHS home warranty. Called Lonestar AC and they came out same day to look at my system. They were professional and very understanding. Wanted to fix the system but after looking at costs we decided to get new unit installed with them. And WOW the service was great. Within a few days had my AC running and the new system is so quiet and the house is cooler than ever!!! Highly recommend Lonestar AC for anyone!

Verified PurchaseLone Star installed a whole new energy efficient green energy Carrier system with the inverter variable speed for the best bid over other air condtioning companies. The ripped out my 17 year old carrier infinity system that had been installed very poorly and installed my new system on a while new base with stands and didnt nickle and dime me to death. Put 2 brand new plenums on the air handler also. I am so very satisfied, Brittany made everything right for us and we feel in good hands for the next 15-20 years, and mist of all on the way to saving $$ on electric bill. I highly recommend Lone Star A/C and Heating, everything done was flawles professional and right.
